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.

  • 53,667 miles
The A/C on my 2002 Montana van was blowing warm in April 2006. At that time my van had 54K miles on it. Since summer was right around the corner, I brought the van to my mechanic and an A/C leak test was performed. $961.91 later, the A/C condenser was replaced along with the necessary parts for it. (official diagnosis = replace leaking A/C condenser. Evacuate and recharge system to specs) August came and once again the A/C was acting up. The air was not very cold and there was a hissing / fluttering noise coming from the vents. I brought the van back to my mechanic. At this time the mileage was 58K. This time it was the rear A/C line/hose that was the problem. My mechanic stated that he typically sees the rear A/C of Montana vans having issues first, not the condenser. And he had checked the rear first back in April and it was fine. So, $482.64 later the following had been fixed: "remove & replace leaking rear evaporator feed A/C tube. Evacuate and charge system to specs." After reading the other complaints, I feel that there may be a pattern here or at least GM did not use efficient parts when they put the A/C units in these vehicles.

(1) bought vehicle as a certified used vehicle with 20,000 miles on it. Just before 32,000 miles, the A/C started blowing warm air. The condenser was replaced due to a crack in it. (2) vehicle now has only about 75,000 miles on it. Once again, A/C started blowing warm air. Dealer is telling us that condenser has a leak again. As an aside, the dealer says if we pay for replacement it has a lifetime warranty, but previous service under vehicle-warranty does not have a lifetime warranty... inconsistent!

My van only had 70,000 miles on it when the air conditioner went out on it, I have only purchased GM vehicles and have never seen this so early in the mileage. My repair man is telling me he is seeing this more and more in 02 Montana's and it will cost over $900 to repair. Will there be a recall on this?
