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.

1999 Pontiac Montana Owner Comments

problem #2

Dec 012007

Montana EXT 3.4L V6

  • Automatic transmission
  • 12,100 miles


PONTIAC SHOULD RECALL EVERY POS 3.4 V6 WITH DEXCOOL.I'm really disappointed that I have to replace a cheap plastic intake gasket that melted away under pressure due to the intake bolts losing torque causing gaps were dexcool can eat at it. The solution to this is: replace with new gasket made of steel @ the customers cost,OH YEAH DON'T get it from gm they think the PLASTIC IS GREAT!!!!!!!!!Hopefully we will all get our money back so day.
