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.

2002 Pontiac Montana Owner Comments

problem #1

Feb 182011

I bought a 2002 Pontiac Montana last year. I didn't have it a week and the intake had to be fixed. There was nothing warning about it except the smell of coolant. It took two weeks for the mechanic to fix this problem. I think GM should fix this for the owners. Canada formed together and sued GM and they replaced the intake on a recall. Why can't the United States get together and do that.

Since I got that fixed, everything and anything is going wrong with it. The present thing is the t valve on the cooling system. It melted about three weeks ago--lost no coolant, but had a lot of steaming going on. Today is March 5 and I have the same problem for the third time. I have to have it replaced again. It isn't very easy to get to and is kind of time consuming.
