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.

While driving, the sunroof busted out. Glass went all unside the vehicle while I was in heavy traffic on the interstate. I almost wrecked the vehicle and the glass scratched up the paint sourrounding the vehicle and the trunk.

On Thursday 1/5/17, upon starting my vehicle, my engine light was illuminated. Today, I had a diagnostic test done and was told the turbo component was not working. My vehicle has approximately 46,000 miles. I read online and this has happened to others with the same mileage. Is there another recall?

While putting my car in drive and in park, there is resistance in shifting. This happens every time I shift my transmission from park, to drive and from drive to park, this issue occurs. I contacted my dealer to get this repaired, and the dealer said it was a known issue but will cost between $500-$700 to repair. This is my sole vehicle that I depend on to take me to and from work, so I have to get it repaired for my safety even though it will create a financial burden.

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.

On multiple occasions my vehicle has been serviced by a Hyundai dealership in South Florida. After "repairing" the air bag signal, it has reappeared on at least four trips to the dealer. After multiple repair (including the replacement of the cables) the following issues still occur; 1) the oil indicator lights and the tachometer lights go on and off periodically, 2) the air conditioner goes off, the comes back again in few minutes, 3) the low air light comes for my tires, 4) engine light, and 5) speedometer indicator went up and down with the vehicle traveling at the same speed. The vehicle is close to 76,000 miles. The above indicated events occurred primarily while driving in city streets. However, some of them were experienced in highway traffic.

My driver side tail light fell out of the casing, driving down the highway during the summer of 2015. Luckily, the wires kept it holding on or it would have flown into traffic. Now, a bit over a year later, in September of 2016, and out of warranty, the passenger side has done the same thing. The dealership refuses to do anything since I am out of warranty. According to Hyundai forums, there are a lot of cars that are having this issue. See this link: also, there is an issue with a $3 clip in the steering wheel. I get a lot of clatter when driving down the road, and turning my steering wheel according to Hyundai forums, my car isn't the only one this is happening to. I have been told it isn't a safety issue, and can wait a bit to get it replaced. It is highway robbery for them to charge $237 to replace a $3 part. But, because it is in the steering column, no other auto-repair places will fix it. I cannot document this as I have not had it fixed yet, and I cannot record the sound while driving...

Takata inflators: Had a car fire from fuel line per fire dept information. I was on the 405 West bound fwy when I started to smell gas and the front hood of the car I noticed black smoke coming out. I got out of the fwy and then parked the car, when someone driving of the opposite direction yelled for me to get out of the car. I turned off the car and ran out to the side walk within a few minutes the car when up in smoke and then it exploded twice. People from the surrounding businesses came out to see if I was alright. The owner of the flower nursery came out and called the fire dept. They arrived and turned out the fire.

I bought my Hyundai Sonata gls 2011, in 2010, and since then there have been several recalls on it. I have done my research, and have found that a manufacturer must repair, replace, or supply a new vehicle to the owner when a recall is mandated. I have taken my vehicle to the dealership for each recall, and what they do is inspect the vehicle, and in most cases, tell me my car doesn't apply to the recall as they find nothing wrong. I am disturbed by this because again, everything I have read, everyone I have talked to, etc... tells me that the dealer must do something in order for the recall to be considered complete. I am driving around in a vehicle with things wrong with it, transporting a toddler, and am stuck with finding resolution on my own. How is this fair to the consumer? the manufacturer has all of its money, as my car is paid off, and my car isn't worth anything for trade or resell due to negligence. If I can make a difference by filing a complaint, and possibly save someone's life, I am willing to try everything and anything in my power to do so.

I made a previous complaint NHTSA # 10896943...I just wanted to confirm when I picked my car up from the shop because my brake lights would not go off which caused my battery to die and multiple other problems, this was actually my 4th recall to be fixed on this car. They confirmed the rattling and lose steering wheel is because the steeling coupler needs replaced. There is no recall and it is going to cost over $300 to get it fixed. While the car was in the shop I found out there was 2 other recalls 6 total recalls since I bought this car. The shop had to order parts for one of the recalls so I am having to take my car back when the part arrives. There needs to be a recall on the coupler as well, if I do not pay to have this fixed and it breaks while driving it could cause me to lose steering which obviously is not a situation I want to put my family or myself in!! this needs to be addressed before someone get seriously hurt or killed due to all these failures!!

Every time I go over a bump in the road even a bump so small most people dont even feel, a rattle comes from the steering column. While in the shop for multiple other recalls I ask them to look at this and he tells me the sterring coupler has been a major issue and probably needs to be replaced but I would need to pay to have it checked. This same issue has occurred on many other 2011 through 2014 Sonatas. It is going to cost over $300 to get it fixed. Given the many issues with this part, it appears to be one of the recalls. I love my car but this is starting to be a bit much seeing how I only have 67,000 miles on the car. Ready to sale it and get something else if Hyundai cant provide a safe and decent care for me and my family!
