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.

CarComplaints.com 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.

I have taken my car into Hyundai 3 times for the same repair on the steering column. I have clicking and chunking in the steering wheel and now my key will not release. I was told this time by Hyundai that it would cost me $150 for diagnostic and thousands if it isnt a related issue. This car is a lemon, and im stuck with it.

Our 2011 Hyundai Sonata gls 2.4 engine caught fire as my wife was returning home from taking our son to school. My wife smelled gasoline and then it burst into flames. This was the second replacement engine covered under warranty and had less than 6000 miles on it. Hyundai mall of Georgia has performed all warranty service work on this vehicle. After the second engine and many other warranty repairs tried to envoke the lemon law but was denied by hyundia case #9412898.

Airbag light on dash board turned on few months ago, the car has never involved in any kind of accident. It is 2011 Sonata and has never been in an accident. The dash board light turned on few months ago after 5 1/2 years of owning the car. I took to the dealer and they ask for $160 for diagnostic and that amount will apply to the cost of fixing the problem if I decides to go ahead of fixing the airbag lighting problem, the dealer gave a rough estimate between $900 to $1200 to fix this airbag issues. They also said the the airbag only warranty for 6 years or 60,000 miles. I though the airbag should be 10 years and 100,000 miles as Hyundai always advertised that. I searched on the web and there are a recall on airbag for elantra but not Sonata. It is definitely a manufacture defected because this is the original airbag and the car has never been in any kind of accident as I mentioned above. I seemed like the 10/100,000 warranty is just for advertisement purpose and they are not really stand behind their product or quality. Btw - I exchanged some email with Hyundai corporation but it did not go anywhere.

About 5 months again I notice that I can not leave my light switch in auto mode because after locking my doors and engaging the alarm I would always get a knock on the door in the middle of the night with my neighbors letting me know that I left my lights on. I did not leave then on because they go off after I hit the alarm but apparently they are coming back on by themselves. I see other people has had the same problem. I don't understand Hyundai at all how many complaints do they need to realize that they made a huge mistake manufacturing these vechicles. I will never by anything thing Hyundai makes again.

Periodically the car unlocks all doors at startup (push button) and you can't manually lock them. Also there have been times that you could not lock the car after exiting when this occurred. The only work around I found is to "reboot" the car. The technicians have run various tests and did not come up with a cause or a solution. This is very unsafe for anyone with small children. This has been an issue with this vehicle since I bought it in July 2010. The last date this occurred was on 9/15/2016. I just entered all the issues with this car, including this safety issue related occurrence on www.carcomplaints.com.

My car would have trouble starting, I would turn on the car but the engine wouldn't start, the lights and radio would turn on and nothing. After the starter being installed on 10/22/2014 the car was fine but then it happened again this year and had the starter replaced again. Then it happened later again and finally had the neutral safety start inhibitor switch replaced. My airbag light turns on and now I have to replace the clockspring. I have other issues with this car like for example my front drive axels being deformed which causes a rattling nose when I turn while driving. I would hear clicking noses on the steering column and had the steering coupling replaced. So far as of 8/12/2016 I have had 15 recalls and I have one to do next week. I'm driving a death trap.

I have had this car a little over a year now. It has made the same noise since I've had it. I've been to the huynda dealer many times. They don't understand what's wrong. When your car is between 2000 RPM and 3000 rpms or steadily at 2000 it makes a continuous raddle noise coming from the engine and continues until you take your foot off the accelerator. You want to know my opinion about the damn car? anyone who owns one should be given a new one. Because the car is a piece of crap. Now I also saw a complaint about someone having to replace the coupler. I have documentation that shows I paid the Hyundai to replace my steering coupler. It was over 300 dollars. When your driving down the road the steering is hard to control and the wheel makes a clicking noise. So I took it in and they coupler needed to be replaced. I want reimbursement and you guys should implement another recall about replacing everyone's coupler. You guys should make Hyundai give everyone a new car who has gone through al the mess we have.

"takata recall"I believe that I owned a defected vehicle. Since day 1 there was one electrical problem after the other. My radio comes on and off by itself, Hyundai fairfax found no problem after three visits, until I just gave up. I replace 7 - 8 blubs in my car, a airbag, and now a socket for my brake light because my came on and off, like other items in my car. It's like I have a shortage or electrical problem with my vehicle. After, they replaced the clock sensor in the steering wheel for the airbag, now my passenger door locks and unlock sometimes. Every time I complain to fairfax Hyundai, they deny that anything could be wrong with my vehicle. I understand that Hyundai desire is to meet safety regulation and customer satisfaction by providing good product. Unfortunately, things sometimes happen. It's when a corporation takes the complaints seriously and addresses the customer concerns, is what grows a business. I have yet had anyone contact me of my concerns since I had this vehicle, after making many complaints. I will appreciate someone taking this situation and my concerns seriously by contacting me with a resolution.

While driving at night, the headlights will turn off when using the turn signal or turning on the high beams, I have to wiggle the headlight switch to get them to come back on. I have sent Hyundai an email concerning this problem as it is a very serious safety issue and the problem is getting worse, but of course there has been no response from Hyundai. With all of the complaints on the internet about this problem. Hyundai needs to issue a recall.
