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.

Grand Prix SE 3.1L V6

I'm confused about the cooling/heating system on the inside. My husband changed the heater coil (I guess that's what it's called), and yet it still doesn't get warm unless it has been driven for a prolonged period of time. We followed directions specifically from our booklet that came with the car. The low coolant light stays on continually, even when full. We are tired of freezing in the winter and burning up in the summer!! Yes, this car has been a pain in the ass, to say the least. Very disappointed.
