Hyundai Santa Fe Transmission Problems



  • Correction: My 2010 Santa Fe, SE. 3.5, was manufactured on 19 Dec 09.
  • a few weeks ago I noticed what seemed like slight slippage ? when driving and the tranny was shifting from 2nd to 3rd or whatever.didn't think much about it but yesterday I started out driving about 30-35 kms when it seemed like it went from drive into neutral for a couple of seconds . Before I realized what was happening there was a very loud bang or thump that was felt and heard by every one in the santa fe. Any ideas what happened.Will dealers even look at the tranny if I take it in or I'am I wasting my time and just wait till the tranny blows up ?
  • Well count me in as another with tranny problems on a 2010 Santa FE. We bought in March of 2010.

    I have the 2.4L engine.

    No problems up until last week. Wife came home and said the car was making a thump sound under her feet. I had just driven the car home from work and noticed nothing. Next morning on way to work I was listening for this thump. Sure enough, not more than a 1/4 mile while braking or giving it some gas, I could hear this thump. Almost sounded like the ABS was sticking.

    Anyway, proceeded on and within the next 1/2 mile, the tranny totally blew. This was after stopping and making a right turn into traffic. Bang. Then a mashing of gears. Metal on metal and no engagement from the driveshaft. Coasted to the side of the road and called Hyundai roadside. My car is 6 months old with 20K on it. Yep, we've had to make few trips so the miles have added up quickly over the summer.

    So, they come and get my car. The grinding is in all movement gears, with Park and Neutral silent. Although the car will not hold in Park.

    Get to the dealer and he basically brushes it off. I am more than P.O'd. This is our second Santa Fe and the first had a premature alternator failure but the tranny in it at 100K was starting to slip.

    Without to much investigation, they order a new, so they say tranny. Say it's the first they have seen! Ya right!

    So they give me a loaner Santa Fe SE. I drive it for one day as it has 5K on it and the TPS tire senor lets go and the tire goes flat. I mean the entire valve stem disappeared into the tire or was shot out of the rim. They are clueless as to what happened.

    Anyway, while getting that problem fixed, I told them Hyundai apparently has a tranny problem as many are reporting problems. They say they have heard nothing. I say to TSB's are out on tranny issues so there must be something going on. Meanwhile folks in the waiting area are looking at me as I grill the service rep. He just shrugs it off and says Warranty! Nice.

    He said not to worry because if the tranny fails again in 20K miles we will replace it again. I said, not with me. I will bring the car back and you can have it. I've had about 10 new cars and about 10-15 used cars over my life and this is the first car that I've had were a tranny has blown in so few miles.

    What is even more disturbing is that when I questioned them on what the damage was, they said they did not know yet. But they knew enough to order a new tranny! I said why have you not pulled it and looked at the driveshafts to see if there is any damage to them? They said, "Oh, we've never seen any damage on those."

    So, on Monday my new tranny will be in and they will begin the process of fixing my car. If I get a call and they tell me there is more damage that they did not know about, I will blow a proverbial gasket. They should have removed the damaged tranny and inspected all the drive components so that they could have ordered all the parts at one time. Silly me for thinking proactive.

    My car is sitting in the exact same spot in the same position as when I left it. They have not looked at anything besides putting a tracking number on my rearview mirror. So they must have seen more than one of these before.

    Now Hyundai needs to come clean and do a recall.

  • I have the exact same issue. Not as bad thru summer when hot, but cool mornings it is back. And no the computer cannot replicate it. Anyone want to buy it? <7,000 miles.

    Purchased new 2010 Hyundai Santa /fe on June 18,2010. At less than 1000 miles, vehicle when cold made loud banging noise in shifting from 1st to 2nd and sometimes from 2nd to 1st and only one time during the day. Problem repeated 2-3 days later, always in AM after setting all night. This is identical to the problem many on this site are complaining about. First trip to dealer (kept it 24 hours). Said they reset computer, raised RPM to about 750. Vehicle ran okay for about two weeks when banging returned. Dealer kept it for 24 hours again, duplicated the problem and reset the adaptive values of transmission per TSB 10-AT-011. Vehicle ran fine until yesterday, Oct 2, 2010 when banging from 2nd to 1st returned even louder and with more force. Do we have a manufacturing defect here? Is Hyundai in denial just like Toyota? Live in California so have recourse to Lemon Law, but perhaps not just yet. What do you think?
  • I think you definitely have the same problem lots of us have. As I have stated in earlier posts, my only "fix" so far is to allow the car to warm up - so that the rpm idle is down to close to 500. (my car cold - starts up idling at 1500 rpm). Once "warm", i do not get the bang.
    I would say there is definitely a defect here -whether its the transmission itself, or the computer, or something else I cant say - but yeah...this is definitely not right.

    The most frustrating part of this story is no one on this board has yet to post that their problem has been completely resolved. There are dozens of posts in which people got brand new transmissions (with the problem quickly returning) - so that tells me its either not the transmission (or they are replacing defective trannys with another defective tranny). There are also dozens of posts mentioning computer resets (and I don't think anybody has said this really worked either). And of course, there are those most disturbing posts in which people say Hyundai has never heard of this problem and the computer doesnt show it and its not repeatable at the dealer and so....there must be no problem...its just in our heads i guess.

    Bottom line: I continue to hope that someone here will post that their dealer FIXED their problem by.............(fill in the blank Please!)

    Hyundai finally changed my transmission at 8000 KM. This has fixed the slipping from 2nd to 3 rd gear and banging when in Reverse. But, this has introduced a new intermittent problem. When starting the engine, 1 out of 10 times it feels like the transmission is engaged. The vehicule does not move but I can feel it shaking.
    Mentionned it to the dealer and they told me to wait for another 2000 KM to see if problem will go away by itself !!! Wow I am very impressed Hyundai!

    Well, I finally turned my 2010 santa fe in to the dealership to hopefully remedy the transmission problem. They used TSB 10AT006 which referred to TSB 09AT002-1.
    They checked the fluid level=GOOD, then RESET TCM ADAPTIVE VALUES and drove vehicle to perform RELEARN PROCEDURE. They stated in the paperwork-"vehicle is shifting correctly at this time" "no further action needed at this time".

    The vehicle is shifting smoothly in all gears(for now!). I still have, however, the delayed " metal clang" from somewhere under the vehicle about 1 second after shifting into 3rd gear (even though it is now a smooth shift). It only does this ONCE-the remainder of the trip(local driving) I do not have the problem-no clang. If I restart the car after about 20 minutes at 500 rpm's(still warm) it is also okay. After a cold start (I wait for the rpm's to get to below 1000 rpm's from the cold start 1500 rpm's) it will "clang" again-and only ONCE. I'm" guessing" that it could be that there is not enough tran. fluid circulating until after the 1st shift into 3rd gear due to the purportedly defect of "tight clearance" between the clutch packs. Anyone else have this problem (with/without otherwise smooth shifts?)

    Rplatner seems to be correct in waiting to get the RPM's down to 500 to temporarily minimize these problems (takes about 30 seconds on a cold start to get it below 1000-haven't yet waited to get the rpm's down to 500). Bottom line: We SHOULD NOT have to endure the inconveniences of looking for ways to help minimize our problems! Who's job do you think that might be!?!?
  • Thanks for that update. It sounds like TSB 10AT006 did seem to help - though all is apparently not perfect.

    I bought a 2010 Santa Fe on May 30th of this year and it has had the transmission problem since the day I got it. I stopped at my dealer and asked if they have had or have heard of any Santa Fe transmission problems and they denied any knowledge. I am researching the Iowa Lemon Law and I am notifying the Iowa Attorney General of this problem and Hyundai continuing to sell these vehicles when they know there is a huge problem with the transmission. I have 7,000 miles on my Santa Fe and the slipping is getting worse. I do not want a new transmission if it will not cure the problem plus it really makes me mad that they will have to tear my new car apart with the possibility of damage while at the dealership. This is a huge disappointment for me and this is the first and last Hyundai product that I will buy.

    Now! If I could also get the passenger front seat to stop rattling on non smooth roads-said they could not DUPLICATE the problem-didn't know Hyundai hired hearing impaired techs (can't miss hearing that rattling seat!) Oh, well-Transmission is more important.

    My transmission failed over 2 weeks ago as I posted what happened in here. Since then, I have gotten a loaner, the loaner has blown a TPS sensor causing a flat and my car is still not fixed.

    Yep, it has now been 15 days and counting and still no fix. Talked to the dealer last Thursday and they have not gotten a transmission from Hyundai yet. Or so they say. Makes me wonder if Hyundai is not having huge tranny problems and none are available, or are hard to get. Maybe mine is being rebuilt, I don't know.

    At any rate, I have begun to check into the lemon laws. Not sure if they are based on what state you bought or what state you registered in. Since I live in SC and bought in NC (I live real close to the state line) it will make a huge difference. NC's lemon laws are much better than SC's. NC's state that 20 working days is the limit within 12 months. So far I have 15. I might go ahead and contact a lawyer just to find out.

    What is distrubing apart from the fact that my tranny went out at 20K (6 months of ownership) is the fact that the dealer has not contacted me at all. I have been the one to call. Yep, I am driving their loaner, but I find it odd that they are not checking in with me.

    We will see. If I don't have my car after Monday, the wheels will start to turn on finding out about my exact position in regards to the lemon laws.

  • This exact thing happened to me last night (2008 LTD AWD, 11K miles) right in front of Portland International airport. It's awesome to sit in front of the terminal, waiting for a tow! I'm disappointed to read that others have experienced this same problem.. repeatedly. Have any of you had the problem resolved permanently or is it still an ongoing issue?

    Hey there everyone,

    I had sort of the same issues as others. I had 18000 kms on my 2010 Santa fe and Sept 23rd when i was driving to work I started to slow down under 40km/hr and the car felt like I went over a huge bump. I didnt think anything of this. The second time again was when I was coming to a stop under 40km/hr again and this time it was a distinctive jolt forward and bang. I had to stop and get gas and when I restarted my car going from Park-to Drive it felt like the whole car just dropped, loud bang, and a jolt forward.

    I had the car towed to my dealership as I was working a night shift. I told my boyfriend what had happened and he looked up this website and told me. The next morning I took it to my dealership and told them what was happening... they never heard of it... and it couldnt possibly be the transmission because it's a new car... the service department was very rude told me I couldnt beleive what I saw on the web and they would call me later. They did give me a rental at this point.

    They called me in the afternoon and told me what I had already known that they will be replacing the transmission and the right front drive shaft. They also told me that when they put it on the hoist that the drive shaft looked like it was shredded... someone please tell me if this is possible since I know nothing about cars, only what I have researched! They supposdily opened up a ticket with Hyundai Canada and sent the pictures of my car to them.

    21 DAYS LATER..... is when they call to tell me my car is finally ready. I have only had it back for 4 days and so far things are back to normal. The reason it took 21 days was because the parts were apparently on back order and had to be ordered from South Korea because they had none in Canada... likely story which they are sticking to and telling me this is an issolated incident. Everything was fixed under warranty and the car rental was paid for by Hyundai oh and did I mention that they had tried to get me to use their shuttle service instead of giving me a rental but I stated that was not good enough not to mention I work 30 mins out of town.

    As I said so far so good, will update if there is anything further.
  • After replacing same sensor 3 times the thing is still doing the same thing , hard jerk as if hit in rearend.Last sensor was ordered online from dealer in Washington state. Really getting pissed on this. Only went 3 blocks last time when check engine light came on this time :mad:

    I have been checking the forums since early summer when my new Santa Fe, all wheel drive Limited started having the problems discussed. The transmission has been shifting smoothly but upon startup it slams and rocks the whole car. My temporary solution to this has been to click the starter momentarily, thus rotating the engine and tranny a little, and then do the regular start; it almost always keeps it from slamming. Since this is a defect, I took it to the dealer here in Ohio, and while I was telling the service rep about the problem I heard a mechanic that was behind him, whisper in his ear that they all do it. Great! He noted the problem in the computer and said he would call, needless to say I have not heard a word in over 2 months. My problem today and the reason I am writing this in the forum, is because I was going up a small incline at about 20mph to 25mph,after the engine had warmed up, and the transmission slipped and then slammed back into gear. This is a serioius problem for longevity, and I am afraid about taking a long trip which may result in a breakdown. I will attend to this with a more serious attitude with the dealer immediately. My car has about 10,000 miles, and has run perfectly. I really like the quality other than this serious transmission problem.
  • we have the same problem except for it does it when you are driving any where from 40 mph to 70 mph and does it without any warning. Had it do this three times on way Chicago this weekend and thought it was going to break down. We have over 100,000 miles and the first sensor was replaced prior to expiring warranty :mad:

    I have a 2010 Sante Fe with similiar transmission problems, hugely disappointing. I looked at lemon law and the service manager tried to dissuade me by saying there is no acknowledged problem to complain about. That after I handed him volumes of posts and notes about the issue. Just today I discover there is a service bulletin finally out that supposedly addresses the problem. I am suspecting a shoddy coverup at this point and will act appropriately.
  • mike519mike519 Posts: 16
    Am in same boat here in Sarasota, Fl. with my 2010 Sante Fe. At this point sorry I bought it-dealer denies a problem. A definate problem with the new 6 speed transmission for Hyundai. They best address it or risk their reputation. I'll file lemon law after next trip to get a fix, the issue is well documented,
  • mike519mike519 Posts: 16
    My previous posts documet the banging issues I have experienced since taking ownership in May 2010. Today the dealer told me he is replacing the transmission. I HOPE that means the problem has been identified and solved, not just avoiding a recall by trading transmissions.
  • changing the transmission does not work, I had mine changed in February and the noise came back, they are replacing the computer module that communicates with the whole vehicle, try to avoid the transmission change it will not fix it, and you will be inconvenienced again. Might want to let your dealer know to check the bulletins sent to hyundai dealers andservice workers, get them to order a new computer instead.

    This is 234 updating my transmission problem to 235,237,240,242,243,245,247,248 and 250 plus any others. Last two days the transmission went from banging to very hard slamming. Took to deler yesterday morning. They are keeping auto to take transmission apart. Service rep admitted that they will likely replace the transmission. He is not specific but says there is a service bulletin out on this vehicle. Mine is a 2010 Santa Fe fwd 6 cyl with 1900 miles. Although there is no firm commitment on part of dealer, I am optimistic.
  • Hello folks. Just finished reading all of your posts. Its disappointing to some of you taking your Santa Fe's to dealers who are poor representatives of the Hyundai Motors company. Just to make some clarification, yes there is a technical service bulletin out for shift quality in this vehicle. And yes, there is a PCM reflash (computer software update) to address those concerns. However, there are instances where that reflash may not work. Thus, you'll return to your dealer for further diagnosis. As a tech, I'm sorry it has to be that way, but its either that, or we KEEP your vehicle for a few weeks to drive and diagnose it (although, some of you have posted you've been without your vehicle for almost a month for transmission replacement? You need a new dealer.) Which would you prefer? So then the next step for us is to verify whether or not it could be a faulty PCM or even a valve body problem inside the transmission itself. Now it does vary from case to case, so jumping to conclusions and condemning a part right away isn't the proper way of getting these things fixed. At my dealer, there has been 3 customers with the same complaint in the last year, and 2 of them were transmission replacements. The other was a faulty PCM.
    The point is, as frustrating as this is, to have transmission problems in a brand new vehicle, please try and remain patient with the rest of us (who aren't trying to inconvenience you, that is) while we get this problem rectified for you. And as a reminder, there are service departments out there who really do care about their customers concerns! :)

    I am fortunate to have a supportive (so far) dealer, so I'm inclined to agree with your perspective. Just the same, my '07 slams into first on cold start every time, but then it doesn't do it again. I just assumed that it was typical of the design, and am hoping that it doesn't turn in to a problem. Is there a connection between this and the problems of the '10 models? I'm presuming that the TSB just covers the new cars.
  • So as I posted before I had the transmission replaced, the computer reset three times and now the computer has been completely replaced and my vehicle reprogrammed so far no issues. They are confident it had something to do with the computer module in the vehicle, hopefully they were right and I never have this issue again its was on going for almost a year.

    I bought my 2010 Santa Fe V6 AWD last month, and already have had transmission problems. Twice the car has jerked very hard and lurched forward when driving about 15mph. The jerk was so hard that at first I thought someone had rear ended me! We have also noticed that it is often hard to put into reverse and the car sometimes lurches very hard when shifting from Park to Reverse and shifting from Park to Drive. This is so dangerous! A recall is urgently needed
  • If I remember right, there is a seperate TSB for your 07 Santa Fe. I tried to view it on the HMA Service web site, but apparently its down for whatever reason. Your problem is not related to the 2010 model year, because you have a 5 speed automatic, the 2010 uses a 6 speed.

    If you're still inside your warranty, I'd recommend taking the SUV to your dealer and talk to them. More than likely there is a PCM reflash to ease the harsh shifting.
  • We wanted to buy a 2010 but couldn't find one we wanted. Then we heard about the transmission issues. WTF. Can't they resolve this effectively by now? What is the problem? It's only a transmission for crying out loud and they've beem making these things for years. Does it apply to the AWD or V6 models more so? What percentage of vehicles are affected?
    I stopped a few people I've seen with Sante Fe's and they had no trouble so they said. One salesman I spoke to who says he sold tons of them, never heard of the issue (of course).
    Lastly, the 2011's are coming out now - is it fixed?
    Sorry for all the questions but just trying to sort it out.
  • Unfortunately for the consumer and Hyundai, this transmission problem varies. What I mean by this is it has ranged from being a PCM software issue, to being a valve body issue in the transmission. Personally, I haven't heard whether or not the AWD transmissions are part of this problem. So far in my experience, it has been the 6 speed transmission on V6 models. 2010 was the first model year to feature the 6 speed transmission, which is Hyundai's first ever 6 speed. This same transmission is used in the 2011 Sonata, 2010 Tucson, and the 2010 Azera, however, the transmission problems only affect the Santa Fe (so far) which were built early in the production year (don't know the dates off the top of my head). As far as I know, none of the other vehicles, such as the Sonata and Tucson have been affected. But then again, 99% of those vehicle will probably still have less than 5000 miles on them.
