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.

Grand Prix 4WD 6-cyl

  • miles
I purchased a pre-owned 2004 Grand Prix in good condition & with low miles in 2007. Shortly thereafter, I noticed water collecting in my passenger side floorboards when it rained. I did not address this when I should have, but that does not dismiss the current facts. The time before this latest flood, I contacted GM and started doing research as to what might be causing the problem. I found many other consumers complaining of the same issue, and found a direct answer from a non GM website, but which has GM 20+ year certified mechanics answering questions. One stated the problem was in 04 & 05 Pontiac Grand Prix's, and the leak/flooding was due to a water deflector kit not having been installed. I printed the information where it showed this being the problem, as well as the 7+ pages from consumers who experienced the same issue. I then took my car to a GM certified dealer in which I was directed by GM to get the auto inspected. The manager in the service department declined to look at the paperwork, stating they do their own diagnostic test. The latest flood had water standing in my back passenger floorboard and caused my blower motor to stop working. After an 8 hour work day, I had not heard back from the dealership, and when I called the mechanic said they still could not find where the leak was coming from. I had a collision in 2010 and they assumed that's what caused the leak, though I repeatedly told them the leak began 3 years before that. The next day I received a call from the dealership confirming what I tried to show them, that my car needed a water deflector kit, and to install it and repair my blower motor would be $400. They blamed it on the age of the car, and the collision I had in 2010. I am surprised and dismayed that GM will not admit or correct this problem, as it is obviously a defect upon manufacture of the auto. I would like this investigated.

Grand Prix

  • miles
I bought a 2004 Pontiac Grand Prix GT2 and I have had a =few problems with it that appear to be quite common the problems are below through 1quart of oil approx every 1000 miles *trouble starting when it has already been warmed up. Ie after I drive around town and go into a store I come out and try to start and it dies right away. It can take up to 6 tries to get it started. I usually have to press the gas to get it going. *headlamps bounce *blower motor keeps blowing even when the car is shut off. After research I have noticed that these problems are all very common in the 2004 Pontiac Grand Prix. I do not think its right that Pontiac has not taken responsibility for this. I bought my car about 3 months ago, I paid $11,000 for a car that is burning oil like crazy and obviously has a bad motor. I think Pontiac should be held responsible.
