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.

2003 Jeep Grand Cherokee Owner Comments

problem #6

Oct 042006

Grand Cherokee 4WD 8-cyl

  • Automatic transmission
  • 60,000 miles


The contact owns a 2003 Jeep Grand Cherokee. While shifting out of neutral, the vehicle surged forward. The contact depressed the brake pedal with both feet, but the vehicle failed to stop. The vehicle crashed into a pole, flipped over three times, and landed on a business sign. Smoke began to rise from the engine and the fire department used the jaws of life to rescue the contact from the vehicle. She sustained injuries to her back and left leg. A police report was filed and the investigation concluded that the failure was due to the accelerator pedal becoming stuck. The speed and engine size were unknown. The VIN was verified and appears to be valid. The vehicle was destroyed, therefore no current mileage was available. The failure mileage was 60,000.
