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. Notes: The 2002-2007 Chevrolet Trailblazer is known for many things, but perhaps it is most famous for its faulty fuel gauge.

This gauge flip-flops more than a politician during election season. Some report that the gauge says "empty" after a fill-up, while others report the gauge says "full" when they're running on fumes. Either way, there's one thing everyone seems to agree on: the darn thing is just wrong.

Following hundreds of complaints and a few accidents allegedly caused by the malfunction, the National Highway Traffic Safety Administration (NHTSA) opened an investigation into the issue in May 2011. Unfortunately for frustrated owners, no recall has been announced.

The contact owns a 2007 Chevrolet Trailblazer. While driving at 76 mph, the low beam head lamps illuminated intermittently. In addition, the contact stated that the thermostat became stuck in the open position. As a result, the vehicle took a longer time to warm up. The vehicle was taken to a dealer where it was diagnosed that the thermostat needed to be replaced. The vehicle was not repaired. The failure recurred on numerous occasions. The manufacturer was notified of the failure. The contact was aware of NHTSA campaign number: 14V755000 (exterior lighting); however, the vehicle was not included. The failure mileage was 90,000.

I was driving my truck heading home and noticed the road looked dark. I pulled over into a parking lot and realized I had no low beams. My blinkers, fog lights and high beams all worked properly. I had to drive home with my high beams on, blinding other drivers. My headlights and daytime running lights have intermittently went out off and on (approximately 4 times) over the past year. I had the dealership look into it the last time I was there and they couldn't find a problem. When researching what could cause both lights to fail at the same time, I came across the latest recall info. I called Chevy and gave them my VIN and was told my vehicle is not affected by this recall. Strange, since I have all the exact same problems listed in the recall and my vehicle has been affected by all of the other recalls on it so far.

Both headlights went out at the same time while the parking lights remained on. The high beams would work when activated. After about 5 minutes both of the headlights came on for another 15 or so minutes then failed again. Again after several minutes the lights came on. This happened at night which limited visibility to see and be seen.

I turned on my car at dusk and my daytime running lights weren't on, and my lowbeam headlamps would not go on either. Blinkers, brake lights, and every other type of light worked, but I was unable to see on my drive home because of the headlamps that would not turn on.

The left turn signal starter failing intermittently sometime last year. Three months ago it started not working most of the time, and now it has failed working at all. I am unable to signal a left hand turn at all. Quite dangerous in a large city with lots of traffic!!

  • 11,600 miles
Low beam headlights went out while driving at night. This is the 3rd time this has happened and it almost killed me because I was on a winding road with no street lamps. It was pitch dark. I threw on the high beams and saw that I was about to crash into the center divider. I was able to maneuver the vehicle and get it back on the road without an incident. I called GM customer assistance center and spoke with [xxx] ext [xxx] and he told me that the recall that is out for this issue does not include my VIN number. I explained to him that I was experiencing the same problem that the other Trailblazers are having and he told me that I would have to pay for this issue myself if I wanted it to be fixed. I need GM to know that my vehicle is having this same issue and it needs to be recalled for this issue. He also told me that your Agency notifies them of when a recall needs to be addressed, not the other way around and that he would do nothing to help me. I have a wife and a son. Our life is in their hands. Please help me get this recall through so other families don't experience the near dead experience that we did.

I was coming home at night and the headlight didn't come on. Tried to manually turn them on and nothing. The running light came on just fine just the headlight wouldn't. changed the light bulb and checked the fuses and no luck. Found out there is a headlight driver module that went bad. That is dangerous if you cant turn them on manually if the auto don't work.

I can smell as if something burning, on different occasion.the headlights would randomly shut off, while driving. I would switch to high beam in order to see. The back hatch window, locks when it wants to. The airbag indicator lights come on and stay on awhile. The vehicle will stall and then accelerate at times. The tire pressure lights, does not come on when pressure is low. The check engine light comes on, and stay on awhile, and then goes off, and comes back on. The climate control heater system blows cold air. At one time the key would not come out of the ignition. Had to continue to giggle the key to get it out of ignition. Noticed my headlights did not come on when I used the remote entry to unlock or lock the door. The windows stall when going up or down. I have contacted GM, but they are telling me that my make, model and year are not part of the current recall. And that the letter they sent me, was to purchase warranty for the vehicle. I feel that this vehicle is not safe due to this electrical problems.

This has happened a couple of times before while I was driving at night (fortunately in well lit areas), I thought I had inadvertently turned the headlights off. When I turned the headlights off then back on the low beams came on. Last night I came out of the grocery store and noticed my headlights did not come on when I used the remote entry to unlock the door. It took a few moments to realize my low beams were still not on once I started the vehicle and put it in drive. My hi beams, parking lights and tail lights are all working. Twenty-four hours my low beams still are not working.

Traveling at 65 mph at 9pm on a unlighted, remote highway the low beam headlights went off. The headlight switch was in the automatic position. I tried all headlight switch positions and determined that only the parking lights worked. I did not try the high beam switch. I was behind a large truck which I followed since there was no location to safely stop. I planned to follow this truck to the next town about 6 miles away. After about 4 miles the lights came back on. I had not noticed any others issues with the lights in the past. I have left the headlight switch in the automatic position all the time.

My headlights went out and would not come back on. About 10 minutes later I was able to turn the lights back on thisis the 3rd time it has happened. I am also concerned because my passenger side window in the front will not roll up or down and I have read about recalls due to a danger of fire / recalls on electrical systems in 2007 Chevrolet Trailblazers.
