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 #1

Optima 4-cyl

  • 100 miles


2011 Kia Optima LX. Car pulls to the left at all speeds but most significantly at speeds above 60mph. This can make for very dangerous situations as the car drifts in all situations to the left. If the road is crowned to the left the car will pull almost violently to the left. I have almost hit median barriers and/or gone veered off the road several times. I can consider myself a good driver without any accidents in the past 12 years and this is unacceptable. Kia has been notified of the issue and is working on the problem. However, Kia has not come up with a fix for this problem.
