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.

2015 Kia Optima Owner Comments

When I am driving my 2010 Kia Optima and go to slow down at 20 mph (only at 20 mph and only when slowing down) my car does a jerk or lurching motion, with a hard down shift to 1st gear.this happens no matter where im driving. From what ive been told theres a transmission update software which when updated. After being updated the dealer has to rset/lear the relearn procedure. Both steps must be done to eliminate the lurching/jerking. I feel there should be a recall for this problem.
