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.

do you believe that this is a problem that started from the factory? I do! and I think that they should fix this problem with the cars and for the ones that has already fixed there cars should be repaid for the pain they suffered and the days they missed from work.

I have a 2003 Pontiac Aztek with duel climate control. When driving down the road with the heater on, the heater stays hot. But when my speed drops below 25 mph or I come to a stop, the heater begins to cool and even become cold.
