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.

Daughter was driving in city traffic in orlando (disney world college intern) and notice smoke and then fire coming from passenger side, under the dash. Car was in motion, she tried to stop the vehicle and exit, had trouble getting car to stop, and the door would not open because the vehicle was not in park. Fire rapidly spread throughout the cabin. She had to put her hand into the fire to get to the shifter, and then hurt her knee when she left the vehicle because it was still moving. The entire interior was totally consumed, all windows are gone, all seats are burnt to the frames, and it appears that the fire department took out the front grill to get to the engine compartment. Unknown cause of fire at this time, vehicle is a total loss, and is now in a tow lot. We will never see the vehicle again since we live in Nebraska. Thankfully my daughter made it out alive with possible knee injury only.

Last summer the windows on my Trailblazer started acting up. Sometime would work, sometimes not. Seem to be affected by the weather, if it was raining. Would stop working all together if it was raining, then would start to work, when it had dried up. I received a notice on a safety recall for my vehicle, but when I called into the dealership, they said that it was not covered since I had not registered in a list of the northern states. I know for a fact that this vehicle was manufactured and driven for at least three years in one of the northern states. Why would it matter if I had registered it here or there. There is still a safety issue with the window module. The recall should follow the vehicle not the registered owner.

I purchased a used car from ez cars & credit located in riverside California because they had some very good reviews. I could of bought a car from a private owner but I decided to go with a dealership because I figured that the law would protect me and they could not sale me a defective vehicle. I purchased an SUV, Chevrolet Trailblazer 2006 on 2/07/2013 and after taking the car for a test drive, I noticed the airbag light on. The manager [xxx] said it was just something that could be fixed in like 5 minutes and that it had to do with the fuses being replaced but his service technician left for the day so I should bring the car in tomorrow. I contacted the dealership and asked for [xxx], I was told by the sales manager who's name is [xxx], that [xxx] was on vacation for 1 week in Mexico. I explained the airbag situation and[xxx]said he doesn't know anything about it and I would have to wait for [xxx] to return from Mexico. A week and a half later driving with the airbag light on, not knowing if my kids, husband or myself were safe in this vehicle but we spent all our money to purchase this car. We here from [xxx] so I brought the car into the dealership, [xxx] had the car for 4 days and the airbag light is still on today! I contacted [xxx] and told him I was on my way to pickup my car, mr. [xxx] he was at the office, now when I pick up my car, I get my keys from the owner of the auto repair shop next door. He doesn't even work for the dealership! I have serious water corrosion under my car, the steering wheel feels shaky the fuel gauge never reads correctly and the lights go off and on inside the car after a while of driving. I don't know what to do?? information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The driver's door controls stopped working and there was an immediate electrical burning smell and smoke. The windows stopped working entirely. It was very apparent that something in the door had melted or burned (no visible appearance of fire on the outside, no flames). I took the vehicle to a GM dealership for repairs, which I opted for based on the severity of the issues and would other causes may be at work (would this happen again" what else was affected"), and they replaced the door control (not inexpensive). I believe this matches GM#12180 and NHTSA # 12V406000. The actual event occurred a few years ago- the date is very approximate and may not be accurate. The area is NJ. There were no out-of-the-usual circumstances with the use of the vehicle. In coming across this while researching it, I thought I would include my event for your purposes. The recall process has been slow; personally not very satisfied, I've spoken with GM and they are still working on sending the letters to reimburse those of us who actually encountered this.

The invoice #130355 from ron sick's for repair was $440.09.

The SUV would not start in October 2012. I was told I needed a new battery, so I bought one right away. I drive the SUV very infrequently, maybe only 40 miles a week. On decmber 7, 2012 the headlights started to flicker while I was driving across the chesapeake bay bridge in Maryland. This was very concerning because it was getting dark out. I drove directly to a friend's house, and when I tried to park the SUV the lights would not turn off. Even after manually trying to turn off the lights and removing the key from the ignition, the lights would not turn off. Finally the lights went out, but the battery was dead when I tried to restart the SUV in the morning. We tried to charge the battery. This caused sparks by the fuse box and the lights inside the cabin began to turn off and on, even with the key out of the ignition. The headlights also started to flicker off and on and the doors locked an unlocked. I had the car towed back across the bridge to my local mechanic and was told I need a new battery. Obviously the battery is not the issue. I would like to know what GM intends to do about the faulty wiring in these models and how they are going to correct the issues related to the recall notice I received in October 2012. The recall number is 12180 and I think this current problem is related to it. I received the notice and it states the parts are not available at this time and to park the vehicle outside. I called and asked if it is ok to drive the SUV and was told "yes". since I must drive across a 5 mile bridge several times a week, I am concerned the truck will break down and cause an accident. I am also concerned a passenger or my pet dog could be injured.

The truck has been at a several times into a chevorlet dealer, the check engine light the reduced engine light and the traction control lights all come on at the same time and it causes a failure in which the vehicle losses 90% of power. The failure happens at random time and all weather and traffic conditions. I have had it at two dealers as well have contacted GM executive dept. They have claimed to be fixed several times but it still fails. The issue at hand is that in traffic conditions this failure proves to be a huge safety hazard for myself and other drivers on the road. Its not a used car issue as its an electrical failure issue. I have asked time and time again to have a GM field tech come look at the car but, they insist that the dealer fix it. I need someone more to see and understand the failure comes with at great risks of other drivers on the road. If you goggle this problem you will see others have the issue and I think its worth a recall if they can find a fix for it but after 3 years and several tries they are still unable to fix the issue.

I came out to my vehicle today, unlocked the door with the keyless remote but the driver's door was unresponsive. Upon starting the vehicle I realized the windows don't work on the driver's side as well. I removed the driver door control module to find a burn mark internally on the door as well as burnt plastic on the door module itself. The window and lock worked fine the night before so I'm concerned with the short circuit occurring over night without a key in the ignition.

Having a problem with the vehicle RPM dropping while idling and the head lights flickering and sometimes shutting off. Check engine light come on and the code said it was the "idle air control valve" it only happens when the ac compressor is engaged. The problem seems to go away when the ac is turned off. Have not had it repaired yet because it's a fairly expensive part.

  • 86,000 miles
I have had several problems with my power windows going up and down and then just not working at all. I smell smoke sometimes but can't locate the cause of the smoke. I have also had problems with the electrical connection to the radio, which also works sometimes but the majority of the time it does not work. I have had this problem for a long time now and need a resolution before my SUV catches fire. I also have problems with the drivers side power door lock which works intermittently-whenever it pleases. I recently started having problems with my rear wiper blade-turn it on and it moves a little then stops. My headlights dim up and down while driving...I have replaced the alternator and the battery and still don't have enough power for some reason-dealerships want to charge a lot of money just to diagnose when it appears that this is obviously a defect in the electrical system of the SUV.
