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.

I bought this car about 4 years ago and it has been nothing but an elecitrical mess. First my head lights would go out once a month, then a couple times a month, then once a week. My brake lights started doing the same. Our famliy mechhanic couldn't figure it out, he just kept replacing them and sending the bad bulbs in for warranty. A couple times the pigtails and lamps had to be replaces. Also 3 seperate occasions both headlights went out at once while driving. And I had to drive home in the dark with no head lights on. I took it the Chevy dealership after the third time abd apparently my fuse box was melted and needed to be replaced. Spent over $1000 doing that and it worked okay for about a year. Then headlights started going out again and brake tlights as well. Not once a week, but still about once a month or every other month. Recently my drivers window stopped working and I couldn't control the master switch to lock my car or roll up my windows. The cluster panel in the door needed to be replaced. Also, had two sensors that needed to be replaced because my 4 wheel drive, parking brake, and crusie control would stop working all at once and the lights would be lit up on the dashboard. I wasnt' able to use any of them until the sensor was replaced. Also the power shorted out in my side mirros, so I can't adjust the mirrors with the control or they start tiliting back and forth like crazy on their own. I have to get out of the car and adjust them manually. GM needs to do a recall, this car is not safe and I will not be buying a GM car while I look for a new car soon.

The driver's side window relay switch is bad. I have had several quotes from dealerships and looks like the cost is around $400. (for them to replace and reprogram). There is a huge safety issue if you cannot roll down your window on the driver's side and roll down and lock or unlock any of the doors or windows from the driver's side as well. I have read many complaints on various websites from consumers with the same problem. With the majority of these switches going bad, they need to recall this, as it is very costly andnot at all safe. Especially if an officer needs to approach you and you have to open your door first. That could lead to an unsafe incident toward yourself as well as any law enforcement agent. If you can please address this issue, it would be greatly appreciated. I have researched any recall on this and have not had any luck. Thank you for your time in addressing this issue.

I have a 2004 Chevy trail Blazer. The locking mechanism for the window failed, allowing my dog to put her foot on the control and roll the window up on her head. As soon as she was trapped I tried to free her, but the window had gotten off the track and would not lower. I stopped the vehicle in the middle of the road and tried to force the window down but that would not work either. Fortunately there was a police officer behind me when this happened and he shattered the window with his baton. If the police officer had not been right there, my dog would have strangled to death. There needs to be some sort of sensor to prevent the windows from rolling up if there is an object in the space. I know children as well as pets have been killed by this and it needs to be corrected. Another possibility is to position the control vertically on the door to make it less easy to accidentally trip.

Blower will go on by itself when manually turned on, the blower will go off for a few seconds and back on. The back windshield wiper will go by itself, the clock will turn to 12:00 when turned off, headlights flicker while driving, when using anything electrical in the car such as the electric windows, the head lights dim.
