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.

Went to dealership and advised of a transmission problem. Supposedly a service flag was sent to dealerships and just "flush" the transmission. 5 days later and 550 miles from home, the car broke down, was towed and advised I needed a new transmission. Still sitting out of state waiting for the part to arrive.

The contact owns a 2008 Hyundai Sonata. While the vehicle was parked in the contact's driveway, his child was able to place the gear into neutral. The vehicle rolled backward, struck a utility box, and drove over a bicycle. When the vehicle struck the utility box, the passenger door was almost torn off. There were no injuries. The dealer sent a packet with paperwork asking for the vehicle description, insurance reports, and pictures. The vehicle is currently at the collision center being repaired. The entire passenger side was damaged. The failure and current mileages were 19,000. Updated 06/23/09. Updated 06/23/09.

problem #1

Dec 242007

Sonata 4-cyl

  • Automatic transmission
  • 186 miles
The contact owns a 2008 Hyundai Sonata. When a passenger is seated in the passenger seat, the air bag light dimmed. The passenger weighed 105 lbs. The dealer stated that the air bag remains off because of the weight of the passenger. While driving 40 mph, the vehicle shook and made a noise. The dealer stated that the failure was caused by a torque converter shutter that was causing the transmission to shift into overdrive. No repairs were made because the dealer stated that the failure was a fuel economy feature and the repair was not allowed. While driving 50 mph, the contact heard a lot of wind noise. The failure mileage was 186 and current mileage was 1,900.
