Print this page 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 headlights work then shut off. (on the way to work in a downpour, no less) dashboard lights partially working. (if I go over 40 mpg can't tell what my speed is) was working correctly for a couple of days now nothing. I checked for recalls and there are recalls for 2006-20xx (NHTSA 14V755000 ) just wondering, after finding on the internet, numerous 2005 owners with same problem, why this model wasn't included in the recalls? I would like to file a complaint on the potentially deadly problem of the 2005 Chevy Trailblazer that should be corrected and included in this recall. Thank you

Multiple times while driving the headlights will malfunction and turn on and off, at random driving speeds under many different conditions. I continued to drive the Trailblazer even after this occurred. Just not as often. If the heater was on while driving and the headlights would short the heater would stop and then turn back on. The fan turns on at random, first it turns on when driving at random times. The fan will turn on at random times with a higher speed and sound. I have had the inspection completed multiple times with a mechanic re-assuring the issue although it has been happening frequently. The check engine light is on all the time due to computer error and is a $500 fix. This has all happened and been reported within the first year I bought the vehicle from kendal motors in lewiston Idaho. I find that the amount of work to fix this vehicle is overwhelming and to see that this vehicle was under 100.000 miles is financially distressing. I have already had the fuel pump portion removed and fixed twice, I had to purchase a locking cap. The stereo repeatedly jams with new cd's even.

Low beam headlights have flashed on multiple occasions in the past. On the night of October 2, 2014, while driving home with my entire family in the car, the low beam headlights went out completely. I turned on my fog lamps to get home. I checked all fuses and relays and there were no problems. I also took it to a mechanic, who secured a loose ground wire. This did not help. Then I heard that GM was doing a recall for this exact problem, but it is for models 2006-2007, and mine is a 2005. They will not honor the recall on my vehicle. I am afraid to take my vehicle anywhere at night or in the rain. I do not feel I should have to pay for the repair when they know it is an issue.

While putting the truck into 4X4 hi, lo, or all wheel drive, the transfer case never does fully put it into 4X4. While driving, the dim lights turn completely off. The brights work, but the dims do not. These will not turn back on until the truck is shut off or a proper bump is hit. The heater blower in the front sometimes will nit come on. The back will be blowing, not the front. Also if a bump is hit improperly, the back speakers will start buzzing.

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.
