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.

2001 Pontiac Montana Owner Comments

Montana 6-cyl

Intermittently when air conditioner is operating, we get a noxious chemical smell from air vents. Odor lasts for several minutes. This is not coming from outside because we are circulating inside air. We see no pattern to this. It happens at times when the temperature is very hot and also when temperature is moderate. We have had the Montana to the dealer three times. They cannot come up with any fix. We are concerned that this may be detrimental to our health. The car stays cool, it's just the awful smell. The cabin filters are perfectly clean.
