Hyundai Sonata Transmission Problems



  • WTF...just stick with the crappy Honda if you got so many complaints about the Sonata!
  • That's not a very kind or helpful response to someone who has already purchased the vehicle and is dissatisfied. This isn't a Sonata Fan Forum - it's for members to express their experiences and opinions, regardless of whether they're positive or negative.

  • My message was 277, I took the Sonata to the dealer who was very helpful, they did the computer flash reset for the transmission (and washed the car), and I have had no further issues, and have put 1000 miles on since the service.

    You my friend qualify for lemon law in most states so I would in act it immediately. Hyundai had more than enough attempts to get the problem resolved and their solution does not seem to be working. Best of luck to you.
  • Sadly the lemon law in my state only covers it if it happens three times in the first year and it has to make the car inoperable. Having the transmission slip does not qualify otherwise Hyundai would have to buy back many cars.

    I have had it with Hyundai and next time will be buying American.

    If I may suggest, do not be surprise you run into similar issues with American vehicles as well. What many do not know is that parts suppliers sell across the board in many different shapes and sizes. I understand the transmission for the Sonata is built in Grand Rapids, MI. Wonder who is supplying the parts for it. I had a Lincoln MKS. At less that 27,000 miles I had the steering wheel column go out, electrical problems, heated seats go out, had to be repainted, left front bearing went out, and a transmission leak. Think about it for a sec, these cars now look so similar why? Same process and supplier? I purchased a Sonata as well and I have had some minor issue that was fixed right away. So far I am impressed with the car and like it was said earlier by someone, it is not perfect. The ride is surprising well and the power it produces (Turbo) is nice. I agree with others about the seating so if I take a trip that will take more than three hours, I will pad the seat some or shop around for some custom seating. Win lose or draw I plan on keeping this one. I am tired of car payment. :shades:
  • The transmission on the one I have was made in Korea it says so o the sticker that comes on the side window of the car-maybe not the later ones but at least this one is made in Korea but the rest of the car is from the U.S.
  • Just bought a 2011 Hyundai Sonata 1.5 weeks ago that was dealer demo w/ 1500 miles on it. Wife called me this morning on her way to work after driving at speed on highway when car lurched made loud noise so bad she thought she may have hit something so she pulled over and got out. After seeing all was well got back in car started it put the car in drive and car would not change into higher gears. >Lashawn, REALLY?? Why not report it?? Well just for the safety factor alone. Not to mention the manufacturer, and any safety boards etc. need to know just this kind of information to prevent any personal injury or death due to problem as well as if its a known issue then people wont have such a difficult time getting the vehicles repaired. Anyways I will keep you all posted as to what I find out.

  • I just changed the 3rd brake light in my 2010 Sonata - what an ordeal! But I did save the $50 the dealer wanted to charge me!

    1. In the trunk, unplug the wire that feeds the 3rd tail light.

    2. Remove the rear seat. Remove two 12mm (I think) bolts about 1/3rd and 2/3rd across seat in crack between seat bottom and seat back (where your rear end would be if you were sitting on it). Pull forward on the two plastic clips in the front of the seat bottom (where you would put your hands to lift up the seat - where the backs of your calves would be). Pull seat out.

    3. Remove left and right seat back end cushions. Remove 12mm bolt at the bottom and wack upward (I did this with a rubber mallet) to unhook it from the top hook. Note: these will be a bear to put back in.

    4. Fold down both rear seat backs.

    5. Remove the thin, black plastic "frame" around the opening.

    6. Remove the small "SRS Airbag" medallion in both “C” pillars to expose the philips screw. Remove the screw and the plastic cover from the “C” pillar. It is held in by the one screw and many clips. You might have to pop some of it out with a screwdriver. Be careful, the side airbags are in there.

    7. Now you can remove the rear deck. It is just held in by one clip (looks like a small yellow drywall anchor) which is visible and accessible in the trunk.

    8. Now all you have to do is remove the housing, I think by removing just 2 small screws, and change the light bulb (bulb #921).

    Hope this helps. Good luck.

    all that just to change out a lightbulb?!!!

    I would trade the car in first!
  • just that to change a lightbulb???-well unless you want ot pay the dealer to do it, then you have to do it yourself
  • I also have a 2010 hyundai sonata which two months after i bought it the transmission did the same thing took it in they computer flashed it. Ten months after started doing it again took it in they did it again. Month after that started doing it again. Now there telling me because its over 60,000 miles its not cover but i took it in the first time when it was under the warranty. I honestly wish they would do me right. But they are trying to give me the run around. Any advice anyone can give me would be appreciated.
  • Looks like they did not fix it correctly the first times so you should file with the BBB first then if that does not resolve it try posting on every internet complaint board, like ripoffreport. When filing with the BBB reference out forums like this to show there is a know precedence that a problem exists.

    Hyundai has a know issue that they have a design flaw and will not "man up" to their customers.

    Good thing to do is also post complaints on all the local reviews of that dealerships, as they will looses tens of thousands in sales. Just complain to everyone a one every where you can and make Hyundai loose a lot of sales.

    Also call Hyundai directly and tell them about this and make sure they know about all the dissatisfied people posting here.

    People do not realize the power they have, especially as consumers - if you don't buy from Hyundai because they have bad products, they will cease to exist.

    Remember their CEO made millions and you got a defective product! Make sure they know you will not tolerate this! Good luck!! :shades:
  • We bought a 2009 Hyundai Sonata and have had the issue of the "jerk" when at low speeds recently, every time we drive. We dropped it off at a dealer late yesterday morning, and they were not even able to look at it before the end of the day. This after saying that they might charge a $115 diagnostic fee! Needless to say, we are not planning on going back to this location. This is unfortunate since (1) it's in a convenient location, and (2) we were planning on purchasing perhaps another Hyundai, Sonata or Elantra, THIS WEEK! Do these issues occur with the Elantra as well?
  • I have the same issue.. I work in a shop that builds vehicles, thought i might change the fluid and see, but from reading here, I decided to call the dealer and find out whats up!
    To many people saying the same thing to be a fluid issue.
    Ill keep you up to date on my issue.

    I also have the same issue with the tail light.... Im going threw bulb afer bulb, until I realized that the socket is bad... If they dont fix it under warrenty Ill fix it myself in the shop.
    I love the car, but Im really thinking I may have to trade it in if issues like these start happening.....

    I just got off the phone with the dealer, they will run the software update for me under warrenty and look at the bulb issue... cross your fingers!

  • ...."cross your fingers!"

    Actually get mad and call Hyundai and ask them why when they have known so long about the defect in their software have they been ignoring it and loosing repeat customers!
  • alexkprojt

    ..oh believe me, I will be asking!. I prefer to do things face to face though, not over the phone, not in a letter, and not on a forum... Im sure it will be fixed to my satisfaction.

    Don't expect Hyundai to really do too much, they already either have your money or know you are legally bound to pay them over time.

    In-fact, within a month of getting my Sonata the driver's seat belt would not lock, it took over a month for the dealership to fix it. I had to put up with risking my life and that damn annoying dinging. When complaining to Hyundai they contacted the dealership and the dealership said it was fixed the same day, however I had paperwork showing they had to order parts and I was waiting three weeks. Hyundai really never did anything to help me and after several calls seemed to get annoyed I was complaining.

    When I called Hyundai about the transmission they just appear concerned that it was documented and wanted to move on to the next complaint. Perhaps they pay or treat the workers at their call center or whomever they contract bad.

    I will never buy a Hyundai again. Like I said they have your money and the money is all they seem to care about! Just make sure the next car you buy is from their competitor and over time if everyone does that they will loose millions in sales and have to listen.
  • alex alex alex.... all is good my freind... maybe you are dealing with a [non-permissible content removed] of a dealership....
    To tell you the truth, when I bought my Sonota the dealership couldnt wait to get me into it, bent over backwards to take care of me...comes to find out they were going bankrupt and needed to get rid of their inventory... so be it... the dealershio that bought them out was Larry H Miller here in Oregon....they rock, took great care of me, and covered the issues I had under warrnty..they even washed and vaccummed out the car.
    I gotta say I had a great experience with them.
    Car is working great more transmission slams !
  • The dealer ship is definitely not one I would recommend however every time I contacted Hyundai trying to get things resolved their customer care phone center did not seem to care too much. I got the impression that all person on the phone wanted to do was be able to close the complaint as quick as possible. They must have orders to get people through fast. Whether or not the issue was truly resolved appeared to take second place.

    The dealership did get me a great price but then their repair department was where they seemed to fail. (Boucher Hyundai / Waukesha WI. More than once I had to come back (especially with the transmission) and several times I had to tell them what was wrong and how to fix it (k up tables in the microcontroller not updating correctly). Tell them it shakes at high speeds and it is was a good chance they would not check it except around the block at 20MPH, get an alignment and I had to come back as it would then pull left.

    I was told later by an employe they were having pay disputes and that is why the mechanics are unhappy. It then reflected in the quality of work. I also think they get bonuses for selling you useless work. With the car we bought a prepaid oil change service plan (big mistake!!). A few weeks ago my wife took it in just to get the oil changed. She called me all flustered as they were pressing her to get work done they said it needed. So she called me and I had her put them on the phone. I was told the car never had the required service maintenance of a front end alignment and that it needed brakes. I then asked what about the front end alignment done a few thousand miles ago that they did and also informed them we had the brakes checked when we brought it into our regular mechanic for a winter check just a month ago and he said the pads are fine. He shut up instantly. Actually had they really did the multi-point inspection they supposedly do with the oil change they would have seen we had a light out which I would have said no to anyways as I already had the replacement bulb in the trunk but had been putting it off.

    Perhaps the same is with the Hyundai's consumer affairs department - pay little and get unhappy workers. However sell a bad product and give second rate customer care and you get your customers leaving and buying from your competitors. Sad to say, many repair trips later and calls to their customer care and it still slips. What a junk car (company)!
