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.

I placed the car in park when I got home from work went inside my house for a few minutes came outside, when I turned the car on and tried to take it out of park it would not change gears. I tried it for almost 20min. I had to turn the car off and back on a few times for it to work. It does it almost everyday. Yesterday 09/14/2011 I had to drive the car away from my job due to an emergency and it would not change gears. I tried after 10min and just left the car behind and had to get a ride from a coworker. If this was a life or death situation I would likely not make it due to this safety issue. This is an ongoing problem.
