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.

problem #3

Nov 122012

LaCrosse CXL

  • Automatic transmission
  • 18,000 miles


My LaCrosse CXL engine has aluminum block with cast iron heads; two metals that cool at different rates allowing coolant to leak into cylinders causing carbon buildup on a 'cold' start. GM knows of this problem; first discovered in the Enclave. Engine no longer in it, but they continued to put it in the use up inventory??

OnStar identified the problem of a 'cylinder missfire' when a diagnosis was requested while driving and the light wouldn't go out. Three visits in two weeks for this problem; the engine can't be fixed and GM knows it !

The engine can't be switched out because of the computers; they identify with a particular vehicle and its pieces and parts.

Force the issue with the Service Manager; have GM provide a solution.
