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.

  • 55,000 miles


1. vehicle made a moaning noise when turning at approximately 55,000 kms (and 3 years old). Replaced power steering pump and steering rack. 2. random clunking from the front end at approx. 56,000 kms. Replaced front bearings and transmission mount. 3. car lost power, had to be towed to dealership. Dealer couldn't find a problem, insisted the car was fine. I insisted on them taking it out again. Car broke down, had to be towed back to dealer again. Replaced catalytic converter and fuel ignition switch. 4. burned through 4L of oil and puffed out black smoke. Dealer couldn't locate problem. Happened again approx. 2000 kms later. Faulty piston rings, engine replaced entirely. At 61,000 kms. Now at over $11,000 cdn warranty repairs on a well maintained low mileage car. 5. random clunking noise in front is back. Going to dealer tomorrow. Warranty: Expired.

Cavalier 4-cyl

  • Automatic transmission
  • 10,000 miles
The contact owns a 2003 Chevrolet Cavalier. Safety defect is automatic transmission. Vehicle rolls back while on a hill. While it is in drive it acts as if it was standard transmission. Happened on and off since 2003. The consumer stated the vehicle idles too low which caused the vehicle to roll backwards.

Cavalier 4-cyl

  • Automatic transmission
  • miles
On moderate inclines the automatic transmission rolls backwards and continues, even accelerates until you brake. Dealer and manufacturer both say this is a design feature and is not a defect. The computer module has already been replaced for other reasons but this unsafe defect continues.
