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.

2002 Pontiac Bonneville Owner Comments

problem #2

Nov 102004

Bonneville 6-cyl

  • Automatic transmission
  • 18,500 miles


The consumer lost steering control while driving at 45 mph. The consumer was able to bring the vehicle under control without being involved in a vehicle crash. The vehicle was towed to the dealer, who informed the consumer that the high pressure hose for the power steering assist erupted. The consumer was concerned since a similar incident occurred before. The intermediate steering shaft was replaced, both front window lift motors were replaced, water leaked in the front passenger door, there was an extreme amount of engine noise as well as heat and exhaust entering the passenger compartment, there was two inches of play in the steering wheel, the steering locked up, there was a lack of power steering fluid in the reservoir, high pressure hose fluid leaked all over the underside of the vehicle and throughout the engine, the upper nut and the bolt that held the intermediate steering shaft to the steering wheel assembly was extremely loose.

Car was brought into otto Oldsmobile dealership with 64K for a warranty replacement of a waterpump and for a squealing noise. Was told the intake manifold was leaking and the estimated repair was 600, with the serpentine belt and the waterpump labor total repair was 1100. Car was driven twice after repair, less than 200 miles when squealing returned and engine seized from coolant entering cylinder number four as a result of the manifold leak. Car sat in dealership for three months while we haggled with them and GM for replacement costs. GM denies responsibility and car had an engine installed from a junkyard at a total cost of 350. Car is currently still squealing.
