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.

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.

Car makes a loud clicking noise in the steering column when going over 60 mph and when slowing down. When parked, there is also clicking noises when turning the steering wheel. When in reverse, it makes a clicking noise when turning. Gas gauge doesn't work. It now will run out of gas when there are "60 miles" left until empty. The cruise control button will not work. You have to keep pressing it to come on. Also, the button to see trip miles, trip a, trip B etc, does not work on the 1st try. It takes many pushes to get the screen to change.

At around 107,000 miles the motor on my 20111 Sonata shut off on the 91 East freeway while traveling about 70mph. I was forced to pull off on the hard shoulder of the road and the vehicle had no power steering or power brakes. The motor started back up eventually but was making a loud noise and failed completely shortly after. I replaced the motor in the Sonata with a used motor and repaired the damage to the suspension and tires.

When starting and moving into a drive gear from park, or while at a stop in drive, the vehicle will suddenly lose its drive letter display and will feel like the transmission is not engaged. This is still occurring after the dealership inspected the vehicle for this issue. This issue has occurred repeatedly. After the vehicle is turned off then on, the drive letter display reappears with the drive letter that I moved the transmission shifter to. When the transmission is moved to reverse, the drive letter disappears again. Sometimes this happens 3 or 4 times immediately in a row. It has also happened while in drive at a stop and has required that I turn off the engine then turn it on again to see the drive letters.

Immediately after starting the car the transmission gear indicator letters in the dashboard were blank and the shifter gears letters were not illuminated. A temporary remedy was to shut off the engine and restart the car. This problem is erratic and cannot be reproduced at will.

Gear shift display on dash board goes blank after shifting from one gear to the next desired gear (I.e. car is in reverse and put into drive, D appears than disappears) or while trying to shift (I.e. car is in park or neutral and shift car into drive and the display goes blank without D appearing first). After the display goes blank, the car feels as though it is going to stall and check engine light appears. Putting the car into park and turning the car off and then back on does not fix the issue right away. After waiting a few minutes with the car off and turning it back on fixes the issue with the gear shift display temporarily but check engine icon remains illuminated.

Vehicle in motion randomly turns on check engine light for a second, will hesitate and then suddenly surge as if trying to catch up. Transmission seems to be the main issue.

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.

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.

After taking my 2011 Hyundai Sonata in for engine recall my steering wheel is now making noise and it moves to the left on its own now. Also my right axle is leaking grease and the car has about 69,000 miles on it. I bought it new.Hyundai dealer said the noise is coming from a coupling and would cost $270. They also said it was not part of the recall for steering column intermediate shaft which I took the car in for when that recall came out.I dont know what they do or if they do anything when they supposedly look at your car due to a recall. My car was doing great when I took it in for the recalls until the last time. Also when I took my car in for engine recall my oil dipstick was yellow. But now I have an orange oil dipstick. Back to the part about the steering noise it makes noise sitting still and moving and sometimes it gets louder if the road is not as smooth.also how do they know it is the coupling and not something else such as what the recall was for when they just listened to my car and not inspect it to be sure. The coupling should have been included in the recall and if not it needs to be recalled.this sounds dangerous. The noise also gets louder when I turn the wheel while driving. Sometimes it sound like the car is rattling and sometimes sounds like a shock absorber starting to go bad.
