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.

Trailblazer 4WD 6-cyl

  • 10,000 miles


Multiple times my Trailblazer has stalled without warning. It tends to happen when I am in a stopped position. Whether it is at a stop light or just stopping in general. It takes a minute and then restarts. It has also multiple times lost head lights. The last time was at 9pm while driving home with my children in the car. My headlights went out I had to pull over and the only way my lights would work was if I held my high beams on.

The date, mileage and mph were either estimated or just ut in since options did not include "unknown". when driving at night headlights sometimes turns off. Only the lowbeams turn off, but when driving with high beams it is dangerous but necessary (especially when on the highways). I called GM and they pretty much claimed that no one had ever complained about it. But I did research and it happens a lot.

Vehicle's headlamps will power surge, dim while driving periodically. Fuel sensor showed constant empty until repaired by the recall. Vehicle will occasionally surge forward revving on it's own at random times. The blower resistor pack has burnt up twice, the blower motor has been replaced as well as the melted the vehicle will not start. The power windows, locks, radio, dome lights, dash lights are inoperative and the vehicle will not attempt to turn over. Seems like this vehicle has had a lot of electrical issues.

I went into town to grab dinner and as I am driving along, my headlights shut off. The only thing that remained on, were the orange turn signal lights. I frantically turned the headlight knob on an off and nothing happened. I was looking for a place to turn off the highway, however it was night time and I had no headlights. I ended up pulling over to the gravel side of the road, and turned the car off. Now I am stuck on the side of the highway at night time, with no working headlights. I turned the car off and got out, tapped the headlights and looked for any physical damage and did not find an answer. Upon starting the car again, it sounded like someone had turned on a vacuum cleaner. The noise pitched up for about 5 seconds before pitching back down. After re-starting the oil pressure gauge moved from its normal position at "12 O'clock" to an abnormal "6 O'clock". I tried to call onstar for a vehicle diagnostic, however now my radio would not work either. I tried the headlights again, and they still would not turn on. I turned on my high beams, and proceeded back home. While en route my speedometer was reading 10mph over my actual speed. When I pulled into my driveway and turned the car off, the speedometer stayed at 10mph. I find it very hard to believe that all of these things happened all at once as a coincidence. This is a huge safety concern as I lost the ability to see at night, as well as the ability to monitor my speed all while trying to drive. Not to mention all of the motorists who were blinded by my high beams on the way back.

Sometimes while driving my vehicle at night(and during the day), within (15-20 minutes into the drive) my headlights go off and do not come back on for a period of time. When this happens I usually have to pull over and let the vehicle sit for a period of time(15-60 minutes). This issue is intermittent and I can not predict when it will happen. But it happens enough that this poses a great safety risk to me and other drivers on the freeway.

While driving it appears that my headlights are receiving a surge of power which causes them to blink as if I am flashing my headlights. This has happened on and off for a couple of years now. Since this has started I have had to replace my headlights about every 6 to 8 months. After the third time I replaced the same headlight my mechanic showed me the fuse and stated that it seems there is a surge of power that causes the fuses to blow. I explained to him that my headlights seem to blink on their own every now and then and we did some research online and noticed that this seems to be a common problem in mid 2000 model Trailblazers. I contacted GM to make them aware with nothing more than a, "sorry for your inconvenience". I have also experienced issues with my door electronics. You can hear the power windows and door locks make a clicking sound as if they are being engaged without being operated. The speakers in the doors do not work after it rains or in very humid conditions. The power windows and door lock button lights work on and off and blink. The door/key chime rarely works. It seems to me that there is a serious issue regarding the electrical system of this model. I recently heard about the recall starting with 2006 models with electrical issues and I really believe this problem is not just isolated to the electronics in the door, but the overall electrical system in these vehicles. Considering the amount of complaints I have researched online it seems that these are common problems with these vehicles. Please for the safety of the consumers consider an investigation and recall into the full electrical system of this vehicle as it could be a serious safety hazard risking fire.

I was driving on the freeway when I noticed my speedometer suddenly went to 100 miles an hour. I knew this could not be the case as my gps showed I was traveling at 55mph. It then went to 120miles an hour and flip. Flopped back and forth. I went to the Chevrolet dealership and they informed me it was the electrical cluster and even though there were many complaints, Chevrolet would not pay for it. The cost to me would be over $500 I live on a small social security check, so could not afford to repair it. Next at 85,000 miles the fuel gauge went haywire and would not register any fuel although I would fill it completely. Also, the lights blink off and on when I am driving at night, so, I am afraid I will be stranded somewhere in the dark with my car quitting all together. This was my last car purchase before I retired and I am just sick that the Chevrolet company will not fix these defects...they fix the same cluster in their Chevrolet trucks....why not in the cars? by the way, I just got a letter last week saying they would "split the cost " to fix the fuel gauge...(my cost is $200 1/3 of my social security check!!

First was the right tail light caught fire and blew fuses, then I get power surges that cause the vehicle to accelerate randomly at the worst times and/or will also stall out, which can be potentially very dangerous or end in a fatal accident, it drops in rpms and lights dim then it accelerates... and the last thing is that the fuel gauge fluctuates dramatically and you can never tell how much fuel you really have... drive 10 miles at quarter of a tank and it either stays close to the same spot or drops and the light comes on for low fuel.

Headlights just shut off while driving. No rhyme or reason to it. Pulling over and flicking the lights on and off for a while usually gets them back on. Exact same problem as the current probe into the same model year of Dodge and Chrysler minivans!
