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.

The contact owns a 2002 Hyundai Sonata. The contact stated that while braking, the vehicle suddenly accelerated without warning. The contact was unable to maneuver the vehicle when it then crashed and traveled up the side support wires for a telephone pole. The contact was not injured. The vehicle was not taken to the dealer. The manufacturer was made aware of the failure and hired a third-party Agency to further inspect the vehicle to determine the cause of the failure. The manufacturer would not provide a cause for the failure to the contact. The vehicle was not repaired. The failure and current mileage was 200,000.

The contact owns a 2002 Hyundai Sonata. When fueling the vehicle, gasoline regurgitates from the fuel tank. Also the check engine warning light was illuminated on the instrument control panel. Sometimes the vehicle will hesitate when attempting to accelerate, as if there was no fuel available. The dealer was notified, and a technician concluded that she would have to pay $900 to repair the vehicle. No repairs were made.. the failure mileage was unknown and the current mileage was 82878.

  • Automatic transmission
  • 80,000 miles


On 09/04/07 I bought a used 2002 Hyundai Sonata and on 09/05/07 the car lost 1st and 4th gear it seemed as if the transmission were going out, but when I started reviewing other consumer related issues I noticed over 900 consumers had the same problems with their Hyundai's, but the cause ended up being the output speed sensor. Which in some cases took consumers up to 6 months to locate one. Unfortunately I financed the car as is with no warranty.
