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.

problem #4

Aug 032006

Optima 6-cyl

  • Automatic transmission
  • 87,000 miles


When I first brought the car and drove it, the lights became dim in the inside and the headlights. The radio turned off and on, took it to dealer 4-5 times for problem and they could find nothing wrong. The car doesn't pick up spend when going over hills not even little ones. The gas needle does not read full even when the tank is practically overflowing with gas. Reading a full tank of gas happens every once in a while. Check engine light comes on. Have taken to shop and was told that my spend sensor is going out and that is why the car is going from 1st to 3rd gear and skips 2nd altogether I've only had the car for one year the warrinty is gone and I was never offered the extended warrinty and really didn't think of it since the car was only 4 yr old. Back brakes have also gone out at least I think so they started grinding with no warning 2 days ago I'm going to have them checked this weekend. Air (never used befoe this summer)doesn't get cold like it should. Door lock making a crazy sound on drivers side, believe the motor is going out on power locks they also tend to not want to unlock sometimes. Atenna broke.air bag light came on and won't turn off. Also how can I find out if any recall items have been fixed on my car or not or if they still need to be replaced.

A/C system takes 15 minutes to start blowing cold air and even then air is not as cold as it should be. I haven taken to two Kia dealerships and both of them say they can find nothing wrong.
