  • Lashawn , What do i use to lubricate the Calipers . My daughter's 2009 Sonata just started experiencing the same grinding noise symtoms as discussed here on this post . Also, with only 45000 miles , if the brake work is needed .. is it a warranty issue?
    Thanks

    No it's not warranty, wear and tear. Typically on most vehicles that's about the right mileage brakes start to wear down, also depends on driver braking habits. You should expect to pay no more than $240.00 to have pads replaced, rotors resurfaced and calipers greased/lubed. If you plan on doing it yourself make sure you buy some lubricated brake grease, any parts store will know what your're talking about.
  • I'm an owner of a 2007 sonata and from day one my back brakes have been a big dissapointment. When I first heard the high pitched noise at 15,000 miles to took my car into the dealiership they said that nothing was wrong and it was in my head. I let them know what I thought. I don't know how many times I have change my back brakes but I still have not change the front ones yet. I still have 30% let on the front ones. If you own a sonata BEAWARE I just change my back brakes two weeks ago and yesterday a grind could be heard from them again I inspected them only to found my driver side inside pad was completely worn off. And the outside pad was dust which happens at very high temps. Look at my brakes my drum must of keep on pushing and worn out the brake pads. I'm shock to see how many others have had the same issues only for the dearliership's to say not our fault.
    Here is the easy solution I'm buying another car and you can bet it will not be a Hyundai

    My mother's 2009 Sonata needs rear pads at 25,000. The dealership gave me the same mumbo-jumbo about rust, etc. and tried to tell me that mileage was the norm for rear brakes. You have to be a real theif to be a service writer. They quoted me $290 for the rear pad job and said it wouldn't need any rotor grinding as i had caught it in time. I was getting the same grinding sound with turning the wheel to the left as I drove and also at start up I would get the same. I took it to my regular mechanic and they quoted me $220. My Mom is pretty conservative and bought the Sonata because of the warranty. She thought she could keep this car longer with the long warranty. She now wants to dump this car as soon as possible after reading the previous posts.

    Wow. If you can do your own brakes, the rear pads are a cinch to change, and they're cheap. The job only takes me an hour and $50, and that's probably rounding up. And 25k miles sounds right, I think. FYI, I get a grinding-while-turning noise in my 07 Sonata every once in a while. This is from the pads getting hung up in the slides. If the dealer "fixes" it, they just take everything apart and clean it all really well, so I now do this myself. Easily the hardest part of a brake job on my Sonata is removal of the front rotors, which I still have not attempted (there's a bolt is a real tight spot).
  • I had an 08 Accord and got rid of it because it ate back brakes for breakfast. I don't know if you all will buy this story but it made the most sense to me. Ever since cars have had electronic stability control people have complained about back brakes wearing very fast. Well someone on the Honda forum suspected the electronics were pulsing his back brakes every time he went around a corner. Makes sense to me but who knows. Honda blamed bad parts Hyundai blames bad parts maybe its really the dreaded electronic glitch. Just a thought and I am sure the experts will chime in.

    Not an expert on the matter but it is my opinion that older cars (pre 2000 anyway) had rear brakes that never wore out because they mostly went along for the ride and contributed very little to actual stopping whereas the fronts did most of the work. Now there is a brake proportioning system in play that distributes braking force more evenly between front and rear therefore it stands to reason that if the rear brakes are now being actually asked to help stop the car they WILL wear out at roughly the same rate as the fronts. Additionally, the change in pad materials that is now mandated because asbestos has been removed (a good thing) has affected brake pad/shoe life. I have a friend who owns and operates a small garage and he has seen brake pad life both before and after the change in materials. He swears brakes do not last as long as before and has to field complaints such as these from his customers. These observations are from regular customers whose cars he serviced before and after the removal of asbestos. So, all these small but important changes have, in my opinion, caused rear brakes to wear quicker now.

    Not sure when you think the change-over in materials happened but I suspect it's been quite some time ago. With that in mind I have a 2002 Mazda Protege with 103,000 miles and about 50% of the original brake pads left (4-wheel disk) in both the front and rear as of about six months ago. This is per a shop inspection. I live in missouri and we get plenty of road salt. So I would beg to differ with people stating that 25,000 is normal. I have had the same type of car from Mazda for the last 20 years and the brakes are always long lived. For what it is worth I think there must definately be an engineering problem with the car. This whole web sight has made me rethink what kind of car i will get next at the end of this year. Should have been a slam dunk with a sanata but not anymore. I don't feel like dealing with some moron who says this is all normal. Been there done that.

    I have an '07 GLS with almost 58K miles. At 49.5K miles I had the front brakes replaced by my Hyundai dealer so they also resurfaced the rotors, serviced the calipers and slides. Since that time when I'm braking or turning at a slow speed I hear a clanking or clattering sound from the front brakes, similar to the sound a CV joint makes when it's in need of replacement. It has no adverse impact on the car's ability to stop. I've had it in to the dealer, they've heard it but can't identify what is causing it. They've also taken the brakes apart and said everything seems to be OK, just keep listening to see if it goes away. It hasn't. Taking the car in next week for inspection and mentioned to my service writer trhat it's still there when I made the appointment - said they'll look at at. Anyone have any idea what it might be?
  • targettuningtargettuning Posts: 1,371
    Yes, it has been some time since the US government banned asbestos from all commercial use and yes, I still maintain that the alternative materials might not last as long but in the end the length of time anything lasts depends on the consumer and their driving habits, good or bad. I just spoke with my sister who lives on the west coast in Portland and inevitably I asked her about her car...long story short, she mentioned she just had to replace the brakes on her 2003 Elantra (a Hyundai product you will notice) at 167,000 miles. When I expressed amazement she said she always downshifts to slow the car (manual transmission). For the record I NEVER got anything remotely near this type of mileage but I have an automatic and routinely drive in the mountains, so is my car defective...I don't think so. So is 25K normal for some? probably.
  • Hi All,

    I am an owner of 2010 Sonata, which ran for just 30,000 miles. Recently, I noticed that during braking (from any speed above 20 mph), there is a sligtly shock or chattering (from breaking system) when the speed reduces to about 20 mph (especially when is car is cold). When the car is warm up or run for a while, this shocking or chattering becomes smaller. When this spedd is below 20 mph, the braking is smooth. I brought this car to the dealer, and they did not find any mechanic issues with the brake pads or rotors. Does anyone have similar experience? How to fit it?

    Regards!

    Joseph
  • I agree with you on the proportioning system as part of the reason for increased rear pad wear. I also think that electronic stability control plays its part, however the design engineers are at fault as well. By not increasing the size of the friction surface for the rear pads to equal the front, it stands to reason that smaller pads, asked to do the same work as the larger fronts, would wear faster. In this case "SIZE DOES MATTER".

    Finally had a chance to leave my '07 overnight at the dealer, they drove it around the parking lots and then on the road ultimately duplicating the noise when turning right/left. They think they've found the source of the problem, worn out bushings on the struts which they're replacing under warranty. Hopefully this corrects the problem, we'll see.

    Wondering if this was ever fixed for you. I am having same issue. Also, how many miles do you have on your car? Did they fix under 100k warranty? Thanks

    target: We have a number of vehicles and have tried to buy those with larger brake rotors front and rear after a cadillac dealer clued us in to "big brakes" or cars with larger rotors and therefore pads. Those cars dissipate heat faster with the larger surface area relative to others of similar weight.
    The 2012 Sonata GLS we have had for 3 months has good size rotors all around so pad life should be average or better. Big heavy truck with small
    rotors and pads seems destined to wear quickly esp. with poor driver.
    Mileage at 2700 miles and the last tankful was 272 miles and 11.33 gallons for 24.0 MPG (computer readout 25.3 or 5% higher with all city driving). Our city includes lots of limited access roads that maximizes FE and limits S&Go.
    24 vs 18 on old car gives us a 33% reduction in gas usage in town. Good car!

    2007 Sonata owner here, had persistent problem with rear brake rotor/pads.
    Many others apparently have this problem, as evidenced on this board and
    this class action suit for 2006-2010 Sonatas in New York. See this link
    http://classactionlawsuitsinthenews.com/class-action-lawsuit-complaints/hyundai-- sonata-brake-pad-rotor-caliper-class-action-lawsuit-complaint/

    We first heard squeaky noise coming from the rear, took it to dealership (24k mi). They said it's rust, and worn pads damaging the rotor, so rotor/pads needed replacement, no warranty! Same problem a year later. They fought tooth and nail to AVOID warranty repair. It's rust blah blah, you pay for it! It's plain for me to see that it's a design flaw, but Hyundai USA/dealers won't admit it.

    I am thinking of taking action contacting state consumer protection and also possible legal action. Just researching now how to get started.

    Honda/acuras had a brake problem which caused a class action suit. End result a reimbusement of $150.00 after buying new brakes and. Sending receipt and some form. To Honda.

    My Hyundai Sonata only has 22,400 miles on it (well within the warranty) and the rear brakes froze and burned up. After braking, the whole wheel assembly became red hot and the extreme overheating resulted in burned pads and a warped rotor. The overheating was caused by the assembly being locked in a braking condition and not releasing. This was due to a DEFECTIVE POORLY ENGINEERED part.

    I asked Hyundai to be reimbursed for my repair based on the fact that the braking parts were defective and prematurely failed. It was NOT a case of wear and tear or misuse or accident. I always have the car maintained by professional shops and I had the entire car, including brakes, inspected at 20,000 miles. The brake pads and rotors were good at 20K. I have never had a car develop brake problems at 22,000 miles! This was definitely a case of defective or poorly engineered parts.

    Here is Hyundai's response: "We have received all of the necessary documentation we needed in order to determine your request for reimbursement. Unfortunately, upon further review of the submitted documents and your Sonata's warranty, we will not be able to assist with the cost of the repair. We apologize for any inconvenience this may cause you."

    I will never own another Hyundai! They don't back up their product. That's probably why there is a class action lawsuit in New York over this exact problem. Maybe we should file one in Ohio.

    Be persuasive and persistent. In my case, I documented all the service record and complaint in writing. Hyundai sent my case to their district rep who decided to cover the parts under "goodwill" repair.

    If you had your repair done at a Hyundai dealer, you might want to start with the service manager to convince Hyundai to repair under warranty. But be prepared, they would kick you like a football to avoid doing that.
  • nj2pa2ncnj2pa2nc Posts: 813
    depends on the dealer and the service manager. The hyundai dealer we use has an excellent service manager. He goes out of his way to make things right. We have dealt with him for almost 10 years now.
