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 #2

Jun 152004

Sedona 4-cyl

  • 10,000 miles


Took Kia, Sedona 2004 4 times to dealer for brake failure. The brakes squeaked a lot, and the problem has not been fixed properly. Consumer took vehicle to the dealer and the problem was fixed. But, then again one could hear a sound on the brakes. Consumer was taken back vehicle to dealer for the 5th time. To see what could be done. Also transmission when in drive around 5 mph, wanted to stop, then jumped to normal. Also when the car was idling in park or stopping it shook.

Sedona 4WD 6-cyl

  • Automatic transmission
  • 1,825 miles
While driving 50 mph vehicle stalled. Vehicle was still driveable. Dealership informed the consumer that there transmission failed. Dealership was notified, but did not resolve the problem. Dealer stated problem was caused by electricl harness. Also having multiple failures with output speed sensor; transmission 3 times; thermostat assembly; power steering leaked; input speed sensor; low ground voltage failed; fuse block problems; cruise control. Consumer was advised that due to the design of the cruise control, the vehicle accelerates often while on an incline at 45 to 55 mph as if vehicle's engine/transmission was racing.
