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.

2004 Buick Rendezvous Owner Comments

problem #2

Rendezvous 6-cyl

  • Automatic transmission
  • 63,629 miles


Service engine soon light came on and the service technician found the mass air flow sensor was not properly connected after the fuel system was serviced. The technician subsequently found the fuel tank harness was corroded and needed to be replaced. The service manager advised that this connector was exposed to the weather elements and if the connector failed the engine would shut off while driving. This is a serious safety hazard in my opinion. The connector was replaced at a cost of $199.50.
