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 a 2011 Hyundai Sonata. My engine is really loud when starting and when idling. When I start my car from the remote start sometimes it will randomly cut off after 2 mins and will cut back on and cut off again. The recall for the engine was made aware in September 2015 it's now January 2016, I know my engine needs replaced and there's something wrong. Every time I get a regular routine oil change I'm told that the oil is very chunky and it doesn't seem to be distributing throughout the engine like it's supposed to. It's taking the manufacturer way too long to fix this issue. This recall with the engine is very serious and I don't want to be injured or die from this recall and waiting for the manufacturer to get things together to fix the problem. I also have a child and I'm currently pregnant and I'm very concerned about this problem. I feel that we've waited long enough for the manufacturer to fix this issue.

Takata recall this has been the worse experience of my life. In may I was driving West on hwy 40 towards raleigh nc when my car just stopped and made a funny noise, when I pulled over and tried to restart the engine smoke came from under the hood. I had it towed to southern Hyundai in raleigh on wake forest rd. It initially took three months to get a response from the manufacturer to pay 50% of the cost. Then 2 months later or around October when the car was ready I didn't have the other $4500 to give them being a single parent of five. When the notice came out I asked them to see the manufacturer for the remaining balance. It is now December and I still don't have my car. I have been through so much and barely hanging on to a car making payments and haven't driven it in 7 months. The dealer still has possession of the vehicle, why can't the manufacture pay for the cost. I feel like I have been a victim of some cruel crime. What to

"takata recall" I was driving on the interstate the other day and my car was shaking, so scary. I'm not a mechanic, but I know when something is wrong. The lights on my car gets so hot that they keep going out and the car is a drifter. I just happen to enter my VIN# in the system and I was shock. I have been driving this car not knowing my car has 4 recalls on it. I would like to get another car because at this point I do not feel safe driving my family even if they serviced it. Just hearing all the problems that wrong with this car, I do not feel safe. Who do I need to talk to about this matter?

My husband was driving home from work and the engine started making a horrible knocking noise. This was on a Friday. We had the car towed to our mechanic the following Monday and he told us the whole bottom end of the engine had failed. Hyundai wouldn't honor our warranty because we didn't have all of our maintanence records for the car. We ended up paying for the engine to be replaced out of our pocket. When hyundia sent our mechanic the new engine it was the wrong one. My mechanic spend the next 3 weeks arguing with them over his fact. Finally after 6 weeks, hyundia agreed to source a second new engine and install it themselves. Even with this decision, they still wouldn't cover it under our warranty. They took an additional 4 weeks to install the engine. We paid for a rental car out of pocket while this was being taken care of. So ultimately, this cost us close to $6000 out of pocket when it should have been covered under our warranty. I will never purchase another Hyundai, nor will I recommend their products to my familiy and friends or anyone else I come in contact with. This has been an horrible experience.

I have a 2011 Sonata, complains of excessive oil burn and loud noise.car burns around 1 quats per 1000 miles.dealer done a oil consumption test and found out its burning too much oil.they wants me to replace the engine.I have done all the oil changes at 3000 miles and its well maintained.dealer said everything is fine with my car as per the 2015 engine recall is concerned.they want me to pay for an engine replacement, when its well known that 2011 Sonata engines have manufacturing defect.I found lot of people having same issue end up in engine stall.its a matter of safety.nobody expect a new model car to burn oil like this and dealer will never say that I was low on oil, when I take the car for an oil change.I found out the problem after randomly checking my oil level.it was well below low.all other cars we have need no top up between oil change.I request NHTSA to take this matter seriously.

I am having trouble starting and completely shutting my car down. When I hit the button to start it I get a rattle noise and the the engine doesn't turn over. When I try to shut it off the display in the car will tell me to shift to park when already in park and the radio will not shut off. I have to re-start the car and move the shift lever from park to drive and back to get it to shut down. This goes on several times some days. Also when I'm driving in automatic, the car will suddenly go into manual first gear and I will have to shift over to manual and back to auto to put it in drive. I had a recall for shift lever problems before but I think there is more to the problem then what they are fixing. This car seems to have many electrical problems. My HVAC also has quit working while driving and had to shut the car down before it would work again.

Case number 8404334 : hi my name is desiret canales I purchased a car on September of 2010 not even a year later started to hear knocking in the engine in 2012. Took the car to mid island- Hyundai in centereach NY 11720 was told that it was due to "lack of maintenance" that the "short block, gaskets tensioners" needed to be replaced. Dealer didn't not give loaner car had to wait 3 months for repairs to be done in the amount of $3889.43. Then in Oct of the same year while on a trip same knocking noise was heard then engine stopped running. Had the car towed to a dealer in Canada, dealer told us that it was engine failure. We told them that according to mid island Hyundai we got a "new engine". repair were made on the car no charge, had to return to new your in a retail car that was was paid out of pocket. Last month we receive a letter stating that car is being recalled do to the "short block" and other issues with the engine. Letter states that if knocking noise was hear coming form the engine to immediately take it to be serviced. I'm sending this compliant letter so I could be reimburse the full amount of the previous repair done in 2012 of $3889.43. Do to the fact that it wasn't my "lack of maintenance" but do to poor manufacturing of Hyundai. Spoke to a rep regarding this issue, she gave me this case number 8404334. Please contact me at 631-872-1587 or email me at sedano09@hotmail.com I'm also uploading all paper work regarding repairs and recall letter.
