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.

2004 Pontiac Grand Prix Owner Comments

problem #2

Nov 182008

Grand Prix GT 3.8L V6

  • Automatic transmission
  • 88,000 miles


I had an accident in the winter of 2008 and after the accident i found out that my thermometer was broken and the car was not running at proper temperature. After a while i started to notice that the heater was not working as it used to. The car would not warm up at more than a luke warm temperature. After I got the Thermometer fixed the cars heater worked as well as it used to and it would once again get hot enough to make you sweat on the coldest of days.

problem #1

(reported on)

Grand Prix GT2 3.2L V6

  • Automatic transmission
  • 25,000 miles

Thought I was being too picky that my heater doesn't seem to get very hot until i heard a couple people talking about the same problem a few days ago. I asked them what kind of cars they had and they said Pontiac Grand Prix and one had a Pontiac Grand Am. Curious if there are others out there with this same issue and if anything can be done to correct it. I have to run the heater on full blast all of the time in the winter, and also have to run the A/C full blast all of the time in the summer.
