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.

2011 Kia Optima Owner Comments

problem #3

Dec 252013

Optima 4-cyl

  • 22,000 miles


Moonroof on our 2011 Kia Optima ex model exploded while traveling at 60 mph December 25th 2013 - evening. Outside temperature was 36 degrees F at the time. Incident also caused body and paint damage to our trunk as well as peppered vehicles behind us with glass fragments. Upon reviewing multiple forums on line it appears this is not an isolated incident for Kia/Hyundai as I learned multiple models made by this duo have also suffered similar scenario's. I'm sure NHTSA is quite aware that the Hyundai veloseter has recalled several thousand vehicles mfg. For this potential issue and we're coincidentally made during the same time frame our vehicle was assembled.
