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.

Contact statesd the windshield wipers will not work except on high. The service dealer stated a bad air conditioning cycling switch caused the windshield wipers to fail. They stated the ignition switch module, windshield wiper module, and the air conditioning cycling switch needed to be replaced, and the computer program needed to be updated. The engine lost all power while driving; there were no warning lights or indication that there was any thing wrong with the vehicle. There was a recal 04V046000 on the windshield wiper motor, the recall was serviced, but the consumer stated the module was already broke. The vehicle will be serviced, but at consumer's expense. The consumer has already filed a complaint on the ignition switch module.

In Oct. 2003, I was driving to work in rush hour traffic and upon coming to a traffic light my Envoy stalled out and instrument panel went blank; car would not restart & message displayed to service engine & contact onstar, I was unable to get Envoy off of road & sat there for 45 minutes waiting for tow truck to tow vehicle to royal Oldsmobile where they said they replaced computer system; since that time in Jan 2004 vehicle was in garage & would not start; vehicle was pushed out of garage & battery was recharged with jumper cables; vehicle was taken to royal Oldsmobile & I was told that battery was leaking & that they had replaced battery; this vehicle has been the most unreliable vehicle I have ever had; I am leasing this Envoy & I am afraid it will stall out again; also last summer without warning, the air conditioning just quit working while driving on vacation; after Envoy was cut off & engine cooled, then air conditioning started working again; this is a leased vehicle & I want to know who I can talk to about turning vehicle in early & also what information is available about Envoy stalling out without warning.

My air conditioner worked fine for one week and after that it takes times when it will cut off and only blows out hot air. Sometimes you can drive for about 30 minutes and it will cut off and other times it takes longer. The fan still blows, but as I say it only throws out hot air. You can stop and cut the engine off and restart the vehicle and sometime it will make it run right again. I have had it at the Chevrolet company to be worked on twice and they finally told me the second time after keeping it for a week and a half that they could not fix it because they didn't know how. They told me they were waiting for GM to let them know what to do or send them a computer chip to place in my computer that would make it work, I think this is unsatisfactory because I called GM and they said that they new nothing about the problem. I spoke with cory jackson at GMC customer assistance center and he is the one who gave me this address to send in a complaint. Could you please let me know if there is a problem and if so when do you expect to have it corrected.
