Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: The 2011 Sonata has a seriously defective engine that seizes without warning. It was awarded the dubious honor of being the first CarTalk / CarComplaints Turd of the Week in late September 2015.

A class action lawsuit was filed in May 2015 against Hyundai that claims the 2.4L Sonata engine is defective. More info here.

As I was driving on the 405 freeway the car shut off. I was able to make it off the freeway but the car would not start again. After having it towed to my mechanic, he said it has something to do with the engine. I looked up the recalls for this car and see this is a problem others have had. Is there anything I can do to fix or get another car?

Engine seized and I had it replaced at a cost of$3,620.04. As per the agreement they made regarding the engine failing due to metal objects being in the engine that was their fault, they would reimburse owners for this cost. I have been waiting over 6 months and when I called, they stalled by requesting me to prove I owned the vehicle by submitting my registration or insurance for the vehicle. I traded in the vehicle last fall and do not have the the items anymore. My name is on the bill I paid for the engine replacement, this is just another way they can try to not pay even they agreed to pay.the engine failed at the savannah airport.

I took my car in to len stoler Hyundai at 11275 reisterstown road owings mills md on Feb 08 2016 for a recall campaign 132 and campaign 136. I was told everything had been inspected and was fine. On Feb 14th 2016 I was driving home late at night on a residential street when I noticed a noise, clicking sound when suddenly the car stalled. I called my son and he tried to start the car. The oil gauge indicator was on and when he inspected it indicated that oil was very low. Which was unusal because at the time of the recall, I was told my oil was low and I also had an oil and filter done. There was no indication of any leaking from the bottom of my car then nor at the time the car stalled. My son put more oil in the car. The car wouldn't start and he pushed it to the side of the road. The next morning I called aaa and took it back to len stoler Hyundai.its been three weeks and they are still fixing it.

II had a recall on several things on my car. Took the car back to dealer I bought it from had the recall stiff done and two week later my starter went out. I informed them there was also a recall for the starter and they argue me down that it was not. Well several people I know with the same type of car year, make and model and they received an notice but when they took it in the recall was found. I had to get my car towed and pay for the repairs in the amount of $575 at for they were trying to charge me over $700. I should not have had to pay for a recall and now trying to find how to file a claim for a refund. My car stop on the street in front of my place of employment I got a jump it made it home and died again on the street call aaa and had it towed to dealer.

Car will not start when I hit the start button. Sometimes it will and sometimes it takes 4 or 5 times to start. Car makes an electrical rattle like noise but doesn't turn over. Also, when I try to shut the car off, my display will tell me to shift to park and the radio will stay on. I've had the car in for the shift lever cable recall but I believe there is more to this. The car is doing the same thing before and after the recall fix. I commute 200 miles to work so the miles I post will be high.

My steering wheel has become increasingly loose and shaky over the past months when driving or stationary. There is a very distinct (and getting worse over time) "clicking" or "knocking" sound when I back up and turn my wheel either way. I was told by my mechanic that something is wrong with my steering gear box/shaft sector and possibly some of my axles. He told me this was dangerous, and that the recall campaign number 097 should cover me. However, I was told by Hyundai that my specific car does not fall under this recall, even though I my car has the exact symptoms of the recall. I was also told that because of recent recalls, my warranty would be extended. However, Hyundai has now told me that my warranty extension only covers the sole engine, and not the axles though they are part of and covered by the initial engine warranty. Hyundai has told me there are "kits" to fix these problems, but I have to pay over $1000 for the kits to fix, even though these were faulty parts by Hyundai. The Hyundai service manager I spoke with told me flat out that my car had faulty parts, but that the kits could fix them. I asked him whose fault it was that they were faulty, and he said that all car companies deal with this and it wasn't because of my driving. But even still so, I have to be the one to pay for Hyundai's faulty parts and non-existent recall help. I'm beyond frustrated after reading so many reviews and forums online of people with the exact same car symptoms as mine who are unfortunately also not covered by the recall. If I cannot get a better response and answer from this, I will be contacting the main lawyer who others have also contacted about this and filing an official lawsuit. I expected way better from Hyundai and am disgusted and disappointed at the lack of service, truthfulness, and integrity from this company at this point.

First, this is my 2nd complaint I've filed. My car has been repaired many times for recalls (one is being done currently for the second time) and other warranty repairs. This is the list so far: Idler pully, tensioner arm and belt, steering column (which broke while driving after I had to get 4 new tires and 4-wheel alignment (24000 miles) that they said I had to get), premature starter failure, short block, leather around gear shifter wore hole in it, and my car has now been in the service dept. Since Dec. 17th because the engine failed again. They ordered a long block for it but Hyundai motors America cannot keep up with getting the engines manufactured and sent to all the dealerships fast enough for the recall.I am now the 12th car down on the list. I still have another outstanding recall for the brake stop pad, and I noticed recently the rearview mirror is faded in spots (dark worn areas). I contacted Hyundai motor America public relations hotline. It took them 2 weeks to get back to me. The man that called me asked for information from me, he called the dealership, and then sent me a letter stating they would only reimburse me a portion of my repairs I had to pay for. In the letter, also was a release of liability for me to sign. That's not going to happen!!!! the release would have made them not liable to past or any future situations, including death. How stupid do they really think we are? they've had well beyond an acceptable amount of time to take care of these recalls. It's time to buy the vehicles back and rebuild their image. If not, there will be more recalls or events that could lead to death. Holding them accountable is the only acceptable way to handle this.people are still out there driving unsafe vehicles!!
