    Ok for the brake problems it is obviously with people living in the snowy states. I live in Maine. So if your car barely sees any snow please don't say you don't have a problem with them. If you see snow and still don't have a problem with you brakes keep it for your self and enjoy your luck. The rest of us don't make it up. If you think so you can trade yours for mine. The dealerships are also aware of that problem and they know about it. And despite the over dozen problems I've had with my car I still like it enough. And if you wish to know in the first year the problems I had are:
    1. Center console was rattling so it got changed.
    2. Mode button on steering weel was stuck and fixed (twice)
    3. Changed rear suspension due to too much noise when going over potholes. And it took me abouth a month to make them understand that this was the problem.
    4. Air bag sensor under passenger seat. (twice).
    5. Splashing sound from the gas tank when full (due to bad design and they know it).
    There were other but I don't remember them on the top of my head. I was every month for something to be fixed the first year. And we got to the point where on the next problem they were gonna give me another car. Well it never happened untill last week. So people that have no problems with theirs we know you are out there but keep it for yourself and don't brag about it pls.

    I don't see anyone mentioning the wheel types they have. I have an 07 Sonata with the "European style" 17" wheels with the 5 big spokes. You can practically see the entire rotor and caliper assembly just looking at the wheel so I'm not surprised that there would be a greater tendency toward development of rust with all that exposure. I live out in the country in the midwest and do, on occasion, have to drive through some pretty deep snow. I replaced my own rear brake pads at 60,000 miles when they started making a rubbing noise and that seems to have fixed the problem for now. I find it interesting that the newer models don't have that wheel type any more, but instead have gone to something a little more "substantial".
  • bhmr59bhmr59 Member Posts: 1,601
    I would think that driving through snow and salt, or whatever any state uses to treat road surfaces in snowy conditions, would get all that gunk on to the rotors, pads etc. regardless of the style of wheels. That stuff gets at the brakes from the inside/underside not the outside.
  • haidonghaidong Member Posts: 17
    I would go small court with hyundai to claim the reimbursement of rear brake repair ( more $400 for the pad and rotor in 32000 miles). It needs 20 minutes statement. Anyone has experience to make the strong statement?
  • newowner10newowner10 Member Posts: 227
    How long do you expect these components to last would be the first question you will need to answer before you go to court.
    You wound have to determine what the industry standard is.
    What does the average Hyundai Sonata get.
    How will you determine these two things?
    Are you going to hire experts?
    The average Sonata get.32K does not sound like a defect to me. 20K indicates under-size brakes to me but I have no data to support my conclusion
  • haidonghaidong Member Posts: 17
    I will not hire experts.

    I found out my brake had defect after I bought the sonata 2 days and the dealer had to do several cut to resurface the rotor. This was the first time they tired to fix my car.

    I asked the mechanic guy to check my brake on 30,000 miles, and he told me the rear pad had 70% left. At 32,000 miles, I heard the grinding noise from the back and sent the car to the dealer. The dealer told me the rear pads were gone and the rotor could not be resurfaced. So the whole real brakes were changed.

    I contacted with Hyundai, they refused to do anything, So I try to seek the help from BBB, Hyundai still refuse to do anyting, BBB arranged the abitrator for me.

    From the begining, Hyundai customer service is pretty bad altitude to me. And they have no intention to solve any problem.
  • newowner10newowner10 Member Posts: 227
    Maybe I missed the beginning of this post but I did not see where you had the brakes inspected at 30,000 miles and at 32,000 they are metal to metal. That is an important part of the story. I would have assumed they wore evenly for 32,000 miles now they wore down from 70% to 0% in 2000 miles. Was the wear even on both rear brakes? How about the front?

    Was the "mechanic guy" the Hyundai dealer or a independent mechanic?
    Someone lied to you if the pads went from 70% to 0% in 2000 miles. Either the mechanic was lying to you about the 70% left statement or he screwed up your brakes. How where the brakes on the front of the car?
  • haidonghaidong Member Posts: 17
    The Front Brake is fine.

    The "mechanic guy" is the independent mechanic. he said the front brake is 50% left in 30,000 miles.
  • newowner10newowner10 Member Posts: 227
    Your original post said 70%. Maybe you should be going after the independent mechanic.
    If I was Hyundai I would say "So your brakes where worn to 50% in 30,000 miles and you had a non-Hyundai mechanic work/Inspect them and 2000 miles later the pads wore out. That sounds like the braking system was damaged/mis-adjusted by the independent mechanic"
  • targettuningtargettuning Member Posts: 1,371
    If I track this failure timeline correctly the rear brakes were inspected by an independent mechanic @ 30K miles...pronounced to have 70% of the useable lining available at that time yet approx. 2K miles later both? rear pads were worn to the point they destroyed the rotors?? I find this to be impossible UNLESS only one side wore in that fashion which to me would indicate a caliper problem. Exactly why do you blame Hyundai since you did not see fit to return to the dealer for at least some services but instead trusted "your mechanic guy" who appears,to me at least, to be less "mechanic" than just "guy" (unless I am missing a whole lot here) then when a major problem appeared you DO go to Hyundai. Then when they tell you that an expensive repair is indicated (but won't pay for your "mechanic guy's" mistake) you start proceedings against Hyundai. I will tell you that unless a caliper stuck no car will blow through the 70% of the remaining brake lining in 2K miles. Not possible!!! If a caliper stuck there would be several symptoms not the least of which would be a drag since essentially the brake would be applied at all times on one wheel that you should have noticed when driving followed closely by the smell of burning brake material next the flames and smoke and last the grinding you finally noticed.
  • billwardbillward Member Posts: 154
    I find that hard to believe, too... if you went from 70% brake left, to 0% brake left, in 2K miles after it took 30K to go 30%, he just blew through 70K of brake pad in 2K miles; what kind of gas mileage did he get? 5MPG? 10MPG? If I see a drop of four MPG for two fillups without a reason, I would assume an issue with the car and would have it in the shop; he's talking gas mileage HALVING or even QUARTERING, and he just went on his merry way. I just can't see it; there would be too much indication of a problem for any driver, even a clueless one, to not say something is wrong. Since I would expect the rear brakes to wear out in 45-50K miles on a modern car, the 70% sounds VERY fishy... unless it was "70% WORN, 30% remaining". If that's the case, Haidong had a bit of bad luck (probably a stuck caliper or something) he compounded by not bothering to pay attention to the signals his car was giving him that something was wrong.
  • haidonghaidong Member Posts: 17
    My original post said 70% left in rear brake and 50% left in front brake.

    Independent mechanic only take a look at the brake. If there is no dust cover, I could take a look at by myself. the only independent mechanic is lifting my car, so we could take a look at the brake.

    when people ask me about hyundai sonata "Cash for Clunkers", I told them should not consider hyundai. 2 people took my advise and buy other cars.
  • targettuningtargettuning Member Posts: 1,371
    Although your reply was directed at "newowner10" I can't help but wonder exactly what has happened here since it has become too convoluted for me to follow. I don't believe you quite know yourself. Since Hyundai didn't respond as you believed they should have to whatever damage or failure occured to your car maybe they didn't for good reason.....Ya think??
  • haidonghaidong Member Posts: 17
    " I don't believe you quite know yourself."

    You are working for Hyundai?
  • newowner10newowner10 Member Posts: 227
    The problem is that the important details come out one at a time. So with your posts mixing with other posts it is hard to get all of the details without writing them down. I think people need to be in-tune with their car when something changes you can immediately react to get it looked at.
    I hear cars go by that are making all sort of noises and it appears if the car moves it is not a concern.
    It was important who said the brakes were good and when.
    It appears Hyundai's part was they built the car. They never said the brakes where good at 30,000 miles and had a complete failure at 32,000 miles. It is important to know if both rear brakes failed or only one side. One side would indicate a problem.
    As i recall a non-Hyundai mechanic look at the brakes at 30,000 miles. This is who you should be after but his pockets are not as deep. If you want yo enter the complete story in one post people could give you an opinion.
  • haidonghaidong Member Posts: 17
    Actually, We pay special attention to the car since most people have the bad experience with brakes. This is also the answer from Hyundai customer service, you have to let the Hyundai trained technician check the brake twice the year. Do you really spend $100 every year to check your brake?

    When I heard the grinding noise, I bring the car to the dealer the first day. When I found the brake, the first thing come to my mind it that Hyundai is using the defect part (do not have the heat treatment right in the process, not right certificated material)

    We should hear the noise ( warning sign) before it is gone, but it does not happen. I think this is the reason that we are not happy. Also we got all kinds of explanation.

    If you check all the posts in this forum, anyone got the warning signs?

    We are not the car specialist, If the car is old, we know it could be wrong. Most people buy Hyundai because it is cheap. So finally we found out it is using cheap materials and cut the manufacture process to make it cheap.

    We could tell everyone that we know how bad Hyundai is. and so less and less people will buy Hyundai.
  • djado_yotsodjado_yotso Member Posts: 4
    I changed my rear pads and machined the rotors few days ago. The funniest thing at one of the dealerships they asked for $450 and the other did it for $160?! WTF. I never got the warning noise before the pads were gone. I kept my old pads. On the left tire I had over 1/4 of an inch left on both. But on the right side one of the pads is gone and it was all metal showing. Now that is far away from normal. Plus when I called Hyundai CS the said they never heard a complaint such as mine about rear breaks. And I'm not trying to convince anybody not to by hyundai but to convince hyundai to do a better job.
  • LASHAWNLASHAWN Member Posts: 303
    I'm sorry dude, but your mechanic blew it on this one or you didn't really pay attention to what he said. There is no way on God's green earth that brakes wear out in 2k miles if 70% were left, 30% maybe but not 70%. I changed my front brake pads at 55k miles because I could feel and hear them going bad. I'm currently at 62k miles and my rear brakes have yet to be replaced, hell my tires still have about 40-45% life left. Hyundai should not do anything for you and if you take them to court with this information you will lose, which means more money out of your pocket for a very simple and inexpensive repair.
  • targettuningtargettuning Member Posts: 1,371
    I do NOT work for Hyundai but I still believe that either you don't know or cannot articulate what it is you think you know so that others here can make reasonable stabs at what your "problem" might have been. I have a modicum of mechanical knowledge and based on what I do know about the workings of ALL disc brakes (meaning most manufacturers because they all work the same) what you state happened is generally impractical unless there are things you did not state.
  • targettuningtargettuning Member Posts: 1,371
    I throw up my hands in dispair....Hyundai is bad, uses cheap materials, a 6x12 inch sign should have popped up in your line of sight telling you "warning your brakes are kapoot" but in the meantime you wait until they are totally worn ruining everything in sight. Yeah, the first thing that came into your mind was Hyundai used defective parts. Yes, you are NOT the car specialist you are the typical car driver who drives on regardless...what owners manual?? Good luck on your next car.
  • newowner10newowner10 Member Posts: 227
    I read the posts again every time I read I realize there is another detail i missed.
    The rotor where cut twice by the dealer first two days. I assume this was a used car. So at that point the rotors where to the minimum thickness and should have been replaced. How many miles did you drive it since you purchased it? The person before you could have been a "Speed Racer" or abused the brakes. Other then the brakes wearing out sooner than expected the car is OK.
    It surprises me when some people have a list of defects on a single car where others have no problems.
    You tell people not to buy a Hyundai because your brakes wore out to soon not knowing what the person before you did.
    I see oil smoke out of Honda's but I see they also have the loud muffler hanging from the back and they are running the car like it is designed to be raced. I would never judge Honda on these cars.
  • targettuningtargettuning Member Posts: 1,371
    Yes, I have been following these posts about this rear brake "failure" and must admit that one single person having terrible problems with one single car leaves a lot to be desired, especially when that one person cannot articulate the whole story.... curses Hyundai...and starts a word of mouth campaign NOT to buy them based on what could be his "independent mechanics" mistake or his own mis-interpretation of what that mechanic told him. Seems that the posters native language isn't english so who knows?/?. I/we DO NOT KNOW if Hyundai had any part in this at all and maybe the blame could be better placed elsewhere. But, I maintain the story as I understood it with its timeline doesn't compute with me anyhow.
  • mfpattersonmfpatterson Member Posts: 3
    With 24,000 miles on my 08 Sonata I started to hear some nasty noise out of the rear end, went to the dealer and they showed me that the rear brakes had worn down enough to hit the rotor! Looks like the inside pads did wear faster than the outside.

    AND the fronts had cracks starting to form. Their quote $430. No thanks!

    I just went and picked up new pads, the rears are small enough for a motorcycle! No wonder they wore out so fast.

    I called the 800 number to share my experience. I still like Hyundai, this is my second one.
  • bchris6648bchris6648 Member Posts: 5
    I am saddened to hear that one person has had an issue with the brakes on their Sonata. I have a 2007 Sonata 2.4L 5M with 32,000 miles on it and after reading this thread I became concerned and immediately went out to my car with a flashlight to see if there was any pads left on my brakes. To my delight there was pad (keep in mind I could only see the outer pads) visible on all 4 corners. I purchased my car new and have never been back to the dealership or any mechanic for that matter yet. I have done all of my own oil changes (I do keep receipts) and tire rotations and find a great deal of satisfaction in this. I will keep it in mind next time I rotate my tires to look at both pads on each wheel a little more closely just in case. On a more personal note, even if I had to pay $450 for new pads and rotors, which would never happen as I would change them myself, I wouldn’t be too upset (i.e. not invoking the lemon law ;) ) because I only paid $13,900 for the car.
  • abramsmmabramsmm Member Posts: 1
    You are not alone regarding rear brakes on 2007 Hyundai Sonata. I bought the car with 31K miles and now it has 53K miles. The brakes never made any noise and never pulled the car to the side, but I always thought the car took too long to stop. Therefore, I had the brakes checked often, and was always told 50-70% of the pad life was left. Both Hyundai and independent shops gave same response.

    Today I had tires rotated and was informed that one side was almost down to metal because the calliper had seized (which suddenly caused one pad to wear very quickly). I received ridiculous quotes in the range of $600- $750 from the dealer and a large independent, to replace all the hardware on both rear wheels.

    I went to a smaller independent who offered a more reasonable quote of $300. He then realized that the other side had frozen pistons. Essentially the front brakes were stopping the car with no help from the rears.

    Once repaired, I stepped on the brakes and almost went through the windshield..... amazing what 4 brakes can do. My assumption is that they were never right in the time I owned the car. Hopefully this was repaired correctly, and not an indication of what I have to look forward to as the car ages and accumulates miles.

    By the way, other than brakes, the car has been OK but not great. Issues with air bag system and some interior parts, etc. coverred by warranty.
  • haidonghaidong Member Posts: 17
    Thanks your post.

    It explains a lot.
  • targettuningtargettuning Member Posts: 1,371
    Stuck or frozen calipers are almost the only way brake pads can suddenly go from 70% pad material to near zero in a very short time. In all my answering posts to one of the others here who complained about just this I used that caveat...that is, the question was asked "did your calipers stick" For the record, stuck calipers are not unheard of in any brand of car. The question to which I have no answer is "do Hyundai calipers stick more frequently than most?" Yes, we have a hand-full of complainers here but overall the number is miniscule. And yes genuine Hyundai replacement parts are expensive as compared to aftermarket offshore (Chinese? Indian? etc) manufacturered parts. As always the question remains are they "as good as" as well as cheaper? Personally I think not.
  • haidonghaidong Member Posts: 17
    You know this is not one person and you said you are not working for Hyundai

    People could read your post as you are expert, you do have free time on the forum everyday and education people. This is the owner responsibility to do bla..bla..

    People need to speak out.
  • etoyocetoyoc Member Posts: 3
    My daughter came home last nite telling me her 07 Sonata with 18,000 miles was making a weird noise from the rear end. I drove it and the driver's side brake is hung up. Called the dealer, first thing the service manager said was that was a maintenance problem and not a warranty item. I am 52 yrs old and have owned dozens of cars with disc brakes without this ever happening. Don't tell me it's not poor design. Can hardly :mad: wait to see what they want to sock me as I'm sure it's cooked the brakes as she drove home about 10 miles with the brake dragging.
  • mfpattersonmfpatterson Member Posts: 3
    You just hit the nail on the head! My friend and I did the brakes on my 08 Sonata and the drivers side rear, inner side, after 24,000 miles was paper thin. The pads had hung up and were always touching the rotor, the rotor also needs to be replaced. I plan on changing the brake hardware too.

    Thinking back I do recall a smell from the rear brakes each time I got home, should have checked them!
  • etoyocetoyoc Member Posts: 3
    Dealer called back and said the pads were gone and backing plate was rubbing on the rotor. Caused by stuck caliper. Said I was "lucky" because it did not gouge the rotors so they could resurface them and replace pads for "only" $150. Right, I feel lucky. Service Mgr said this was a maintenance item on Sonatas. I asked her to show me where it was indicated in the owners manual that this was a maintenance item, of course it isn't. She said I should have them do "brake maintenance" (for $50) approx every 20,000 miles to remove corrosion and brake dust and lube the pad slides. This is poor design andnothing but. Isn't the NHTSA interested in brakes prone to fail such as these on Sonatas? Sounds like a recall is in order here....
  • targettuningtargettuning Member Posts: 1,371
    I am NOT working for Hyundai in any capacity. As far as being an expert...I am not, but do have some common sense. As for the rest of your post I do not know what you are talking about!
  • targettuningtargettuning Member Posts: 1,371
    Check around, there is one basic design for disc brake calipers....THEY ARE ALL BASICALLY THE SAME. Some expensive luxury cars and a lot of sports cars have a 4 piston caliper but no common car has them. If there really is a "design flaw" on late model Sonatas I am unaware of it (that is, nothing I have read in any trade publication says so) despite some here insisting there is. If you feel so strongly there is a problem send your concerns to the NHTSA complaint site. Oh yeah, I still do not work for Hyundai or in the automobile industry. I am an electronics engineer working for the ARMY. Just because I am interested in all things automotive doesn't mean I work there.
  • iggypopiggypop Member Posts: 3
    I have the same problem as as lot of other Sonata car owners with the back brakes.
    I changed the pads and rotors and within a month I was getting a high pitch squeal and abnormal wear. I changed the brake pads to a better type and still get noise.
    The stainless holders for these brakes seems VERY tight and does not let the pads loose.
    Has anyone removed these holders or modified the pads to fit better?
    Thanks
    :mad:
  • haidonghaidong Member Posts: 17
    So you owned Hyundai?

    why do you have so much interest to stay hyundai board? And you do no know people are talking about. But you do know the brake has no design problem, no materials problem, ....
  • targettuningtargettuning Member Posts: 1,371
    Why so much interest "to stay Hyundai board" ?? Yes, I owned Hyundai....I happen to have had two Hyundai products personally (2003, 2004 Santa Fe), my son had a 2000 Elantra that when sold had 193,000 miles with no significant problems, my daughter still owns a 2003 Elantra GT. I happen to like Hyundai and plan to buy a 2010 Sonata hybrid (if they release it for 2010) trading in a 2006 Civic that we do not like. Beyond that, I like automobiles in general and yes I can figure out what people here are complaining about but do not know why. I could be wrong but have seen no evidence elsewhere (yet) there is a large problem. Many, not all, complainers have "previously owned" Sonata's that may have developed brake problems that could be the result of having been mis-treated or neglected by a previous owner and while there may be a sweeping problem involving all 2006-09 Sonata's it doesn't seem likely. So, you too can register your specific complaint with the NHTSB...
  • ayeuayeu Member Posts: 41
    Targettuning - regarding your assumption about previously owned Hyundais, please see my comment #24. Mine was brand new - 21,000 miles in 11 months, i.e., lots of highway driving and not much braking. I might add that I take meticulous care of my cars, driving them all over 100,000 miles. Furthermore, I usually do my own brake work. You mention neglect. I don't understand what could be neglect other than ignoring pad/rotor replacement when needed. My brakes seized and had to be replaced way too early. Good luck with your new Sonata. Your older models may have had less corrosive pad bracket material. It's the pad brackets that are the problem. Perhaps you live in the south, or somewhere where road salt isn't used? I would invite you to call Great Lakes Hyundai at 330-422-1212 and ask the Service Dept. what brake maintenance is recommended on a Sonata (and why). Last spring I was on vacation in St. Augustine when my power seat switch stuck (later became a recall). Hyundai of SA replaced it under warranty and I took the opportunity to ask them about Sonata brakes. They said they get a lot of northern Sonatas with seized brakes. Feel free to call them, too.

    Please do not make this personal. You are free to accept or reject any information you find here at your discretion and you should be careful not to accept things posted "on the internet" at face value, absolutely. But if you aren't crazy about any particular member's posts, the thing to do is just skip them.

    Thank you for your cooperation.
  • etoyocetoyoc Member Posts: 3
    Tell you what targettuning, if you are really in the Army all I can say is God bless you and I hope you remain safe and thanks for what you do. As far as the brake issue, I realize all brakes are fundamentally the same, however there is something about the Sonata rear brakes that causes them to fail at a rate much higher than other vehicles in the Salt Belt. I've had enough cars in my life with rear discs and NEVER had them wear out or fail. I talked to a woman at Hyundai Consumer Relations who told me they couldn't do anything because the brakes are a wear item. I asked to speak to a Supervisor, waited on hold for 15 minutes, then she said Supv would call me back later. Still waiting. I did submit a problem report on the NHTSA site. I think a rear brake lockup is worthy of that. Hopefully everyone else with the problem will do the same because Hyundai is ignoring us.
  • LASHAWNLASHAWN Member Posts: 303
    I live in Savannah, GA and I'm glad we don't have that problem down here. I have an 06 Sonata LX with over 60k miles and I had my front brake pads replaced at 55k miles and the rear pads have not needed replacement yet. I hope everything works out for you.
  • targettuningtargettuning Member Posts: 1,371
    Please note..I said "many, not all" may have been pre-owned and the context of my "neglect" comment was regarding those cars who may have been pre-owned since according to you there is a recommended brake maintenance. Also, I happen to live square in the middle of the so-called "rust belt" (in Pa.) I also concede that there may be a little known brake problem on rust belt cars and rest assured that if it is a result of material too prone to salt corrosion Hyundai will soon modify or otherwise correct it since from what I can tell they (Hyundai) seem to be "on top" of problems e.g your stuck power seat that became a TSB issue (probably this instead a recall). With that in mind I have little fear in buying a new Sonata or any other Hyundai product. In fact I wish I could justify (and afford) a new Genesis sedan!!!
  • targettuningtargettuning Member Posts: 1,371
    Thank you, but although I have served (USAF, Vietnam war) I am currently a civilian working for Uncle Sam (Dept. Of The Army). As I posted recently I concede there may be a "material type" problem that renders these rear brakes more prone to quicker wear-out due to some type of sticking than other makes. But, if the rears are subject to this type of failure why not the fronts? I assume Hyundai utilizes the same materials and designs for all calipers/pads/and related hardware both front and rear. Not to mention these materials and designs are possibly used on other products within the Hyundai line up. This begs a further question....are these types of "failures" showing up on Sante Fe's, Elantra's or any other Hyundai product??
  • ayeuayeu Member Posts: 41
    Target - I'm serious when I wished you good luck. Doesn't PA use only cinders? Anyway, when you buy your Sonata, do yourself a favor and check your brakes at about nine months, though. Regarding a Genesis, I would check timing belt replacement cost before buying one. The Sonata has a chain which never has to be replaced (I know - never?) but the Azera, for example, is a $1000 timing belt replacement every 60,000 miles - mostly labor. I don't know if the Genesis is the same engine but many are not aware of such maintenance costs before they buy. Don't get me wrong - other than the first premature set of rear brakes and a seat switch (dealer called it a recall as opposed to a recent stoplight bulb TSB), my Sonata has been problem free. I just drove it to FL from OH for the sixth time (those highway miles again) and got 33+ on the highway. The brakes definitely are a problem though. They are very noisy when turning and braking because of the earlier preventive maintenance. Regarding the noise, the service tech told me "that tells you the pads are moving and they're not sticking". Not sure I'd buy another one but haven't ruled one out. Maybe pre-negotiate the brake service! BTW - looking at comments for the Santa Fe and Kia Optima and Sorento, they have the same thing going on. Good luck and thank you for your service to our country. Back to PA - when did they start using salt?
  • targettuningtargettuning Member Posts: 1,371
    I have lived in Pa all my life (62 years) with the exception of military and misc. short times spent in other states for schooling and various other reasons and it seems there hasn't been a time Pa didn't use salt. Depending where in the state you live (some areas get much more snow/ice than others e.g. the mountains and around Lake Erie) its use varies from merely a lot to ridiculous. Pa road crews would much rather salt than plow it seems. Worse yet, there is a combination of salt and small "rocks" so not only do you get salt corrosion but the rocks chip the paint allowing corrosion a foot-hold. Cinders? I wish..and now the state is using a "liquid pre-treatment" so corrosive it rusts the (large diameter) bolts holding the sprayer and other attachments to the truck off in one season. In fact after this happened to their trucks the state changed to stainless steel hardware. So, corrosion is a large issue here, now more than ever.
    Regarding the Genisis..both the engines, the V-8 and V-6 use timing chains. Also, I was/am unaware of rear brake issues with other models in the line, will have to research more before shooting off. Still cannot figure why the front brakes don't suffer from these problems using the same materials and designs.

    I agree. The only theory I can come up with is the front wheel leads and kicks up the spray that coats the rear wheel assembly. How's that for a shot in the dark?

    @ayeu,

    I think you're mistaken on the timing chains. Azera, Sonata & Genesis all use Timing Chains & not belts. A timing chain doesn't need to replaced during the normal life of the car.

    Wobbly - maybe semantics, but the guide below calls for replacement of whatever it is (belt or chain) at 100,000 km(appr. 60,000 mi). It is >$1000 cost. When I bought my Sonata I was looking at a Tucson. The salesman erroneously told me the Tucson timing belt cost $1000 to replace. After I bought the Sonata, I asked the Service Mgr. why the Tucson belt cost so much to replace. He said "The Tucson belt costs about $400 to replace. It's the Azera that costs about $1000 because it is so hard to get at"

    I like the tighten "under carriage nuts and bolts " every 3 months or 5K kilometers. I have never heard of that.
    Does anyone "Edmund's" calculate the cost of maintenance in the price to own?

    Fuel pump Filter screen replacment? What does that cost?

    @ayeu,

    The website you're pointing at is Hyundai Phillipines. Maybe there Hyundai suggests replacing the timing belt. However, I'm looking at the manual for US spec Azera & it doesn't mention anything about it. Infact, I even called a mechanic friend of mine & he told me that timing chains aren't meant to be replaced before 100k miles (if at all).

    The timing belts need to replaced at 60k miles. The belts are made from rubber/asbestos/polymer compounds. The Timing Chains are made from metals & are designed to last longer. The reason why it costs 1000k replace the Timing Chain in Azera is that it isn't meant to be meddled with unless there's something wrong.

    Add me to the list of 08 Sonata owners with shot rear brakes at 19,000 miles. I should begin by stating the assistant service manager told me it would me cost $115 just to have them LOOK at the car, although he admitted he heard the grinding when we first drove into the service bay. The brake job cost $295 and that was only because the rotors were still okay. The front brakes still have 80% left. Later in the day the service manager gave me a lengthy speech about how the "slide pins" on the brakes need to be cleaned and lubed every 7500-15,000 miles and that if we had had the "15,000 mile routine maintenance" performed on time "this would never have happened". I asked him if this "slide pin" maintenance need was unique to Hyundai because in nearly 40 years of owning cars I have never heard of this. In fact we own a Toyota with 100,000 miles on it and it has only needed the brakes redone once...and like all our other cars, it has never needed any type of "brake maintenance". Obviously these service managers think we are all idiots.
