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.

This complaint involves the rear liftgate wiper not functioning. It first started by running slower and slower, then finally stopped functioning completely. I have replaced it twice now, and both times the wiper motor would function for a very brief time, the first time around it didn't last for 36 hours before ceasing to function again. I have been to numerous forums to research this problem, such as, and it is quite apparent to me that this is a widespread issue, with little hope of an easy repair. It appears the suspect part, the lgm, can't be ordered or replaced by the common man, and many of us do not have the financial resources to continually be taking the vehicles to the service bay of our local Chevy, GM or Buick dealer. This is a safety issue for many reasons, but particularly for those of us who live in a rural environment of dirt/gravel roads as the draft at the rear of the vehicle always causes the lift glass to become soiled, reducing visibility to near zero at times, which makes for less safety when changing lanes, backing up and so on. Additionally, there has been no solution issued yet for the flickering headlight issue that a recall was issued for last year for these vehicles. This is becoming maddening, it has been far too long. Apparently none of the higher ups at GM live in regions where there is a substantial deer population. Thankfully I have yet to hit one. It would seem to me that this problem is given very little attention by GM.

We were traveling from spokane, wa to portland, or, when we got to richland, wa the check engine light came on. We stopped and scanned the computer and gave us a code for a faulty pedal sensor. We erased the code and turned the Trailblazer on and it came back on in about 10 minutes. We read online that other people that have Trailblazer ss are having this issues and there was a recall on the sensor and they are getting theirs replaced. I talked to autonation Chevrolet and camp Chevrolet here in spokane, wa and they both have heard of the recall and the issue but since it won't show up under my VIN number they will not honor the recall. They won't 100 to 150 to diagnose when it took me 5 seconds and they want us to pay about 600+ dollars for an repair that should be free. I read about the sensor and our truck is doing everything it says it will do. When you are at a light and go to push the gas pedal it boggs down like about to die then lunges forward and shifting hard between gear 1 or 2. can someone please help us with this and help us get the dealership to work with us. If we continue to drive it an accident could happen any moment. This is a huge hazard!!!

I recently purchased this vehicle 3 weeks ago from a dealer in St augustine, Florida. The engine will just shut off when I am driving, I have two young children and am concerned that this could cause an accident when driving. I have not been able to get any help from the dealer where I purchased the vehicle even to do a diagnostic on the vehicle. Has there been any problems/ recalls with the ignition switch on this make and model, even when at idle it will shut off, without touching anything.

Hello, my name is [xxx] owner of a 2006 Chevrolet Trailblazer. The issue with my vehicle is that my wife was driving it down a highway in northern Michigan, driving at about 45-50 mph and the vehicle just shut off while driving. When the vehicle shut down she lost power to steer and brakes. If this incident happened in the city or on the freeway this could have been fatal. I called Chevrolet and started a claim, the person I talked to couldn't speak much english or understand it as well. I told them what had happened and they wrote back with a entirely different story. They sent me to a local dealership, to get advise. The only thing they could tell me was there is no recall on that switch. All I was trying to do was make Chevrolet knowledgeable about the situation. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The drivers side low beam headlight was not working. When my dad opened the hood there was an aroma of burning wire. My dad removed the rubber cap for the low beam headlight and found the plastic electrical connector to the low beam bulb was burnt and charred. My dad removed the connector in order to avoid a fire. I contacted GM customer service and they informed me that there was not a current recall for my VIN number and that I would have to take it to a dealer for repair. I contacted a dealer and they informed me that the repair could run hundreds of dollars and they could not confirm that the problem would not happen again.

Engine light came on and never went off. Have had in garage 4 times and no one able to fix. I have had every code fixed and cleared but light still stays on. The last time in shop light was off when all codes reset and as soon as I drove it a short distance, light returned. Now light goes on and then off and on again. It can last for days or a short drive. Car runs fine and no one can see to find problem.

(on or about Jan 9, 2015) upon driving at approximately 40 mph, the 2006 Trailblazer stalled. I was very fortunate that no car was behind me since it was a two lane highway, and I surely would have been rear ended. At that time the passlock light lit on the dashboard. I immediately put the car in park and it started. (again on Feb 4, 2015) driving on a three lane highway and traveling at approximately 25 mph (intending to turn left in a approx 50 yards) in the middle lane, the Trailblazer stalled. Again the passlock light lit on the dashboard, I again quickly put the car in park and it started. Again we were fortunate not to have a car directly behind us, or we would have surely been rear ended!

The problem started on Wednesday January 21, 2015; I started my car up to let it warm up while I dusted off the snow. I notice my heated seats were not working. I turned the car off and restarted it. As soon as I restarted it the car began to backfire and stale. It would start but then stale out. I had to get the trucked towed to the local mechanic. I pick up my truck that evening and it ran fine. The next morning Thursday January 22, I got in my truck and it started right up. However, every stop I came to the truck just shut off. I restarted it and then would just shut off at the next stop. The engine light did not come on until I was drive to the mechanic. Again that evening I picked up my truck and everything was fine. Friday January 23, I was driving my 7 year old to school and the car just shut off while I was driving down a steep hill. I had no brakes or steering. This happened 3 times. I again took my car to the mechanic. He kept my car for 4 day. I finally picked it up yesterday January 24 and it is still not fixed. My mechanic said he is stumped. It drove great after picking it up. Then this morning January 25, as I was taking my daughter to school, my car shut off 3 time while I was driving down two hills. Then it staled 2 more times while I was a red lights. I nearly missed two accidents. By doing research online I found hundreds upon hundreds of complaints from people having the same issue. I call the local Chevy mechanic and he said this is an known problem. I called Chevy directly and they too are aware of the problem and number of complaints. I even found complaints on this very site. I'm just curious if someone has to die before this problem gets fixed. I have a recall on my drivers door for a part that catches fire, but no recall for the truck just shutting off when in motion. Doesn't make sense to me.

On Tuesday, October 21, 2014, at approximately 11:30 a.M. while my husband and I were driving on the West side of the standing rock sioux reservation my 2006 Trailblazer ext caught on fire. We both smelled smoke, parked (didn't turn off the ignition) and flames began to shoot out from underneath the front driver's side of the vehicle. We got out and ran to the West side of the roadway as the fire engulfed the entire front motor area. My purse was still in the burning vehicle and I told my husband he ran back to the burning vehicle to retrieve it. He sustained burns to his hands, face, legs and feet. In addition he received smoke inhalation to a degree of a "black out" stage. We witnessed the tires burn up one after another, beginning with the front driver's side, then the passenger side, the rear driver's and the passenger's side - at this point we moved further away from the burning vehicle as we expected the car to explode once it reached the gas tank area, but somehow the gas tank didn't explode. In fact, the spare tire which sits underneath the gas tank received a slight singe and did not burn (along with the gas tank). The only warning we had was the "smell of smoke" - the Trailblazer's dash warning light did not appear to indicate anything was wrong. In addition, on or about October 25, 2014, another Trailblazer (same area) also burnt up (as reported by bureau of land management).

My door module went bad. The part has a recall, the manufacture doesn't have a fix. The manufacture wants me to pay for another defective part. Then reimburse me when they have the fix. I couldn't make sense of this since the part is under recall just swap it out for another defective part. When ever they have a fix let me know I will take my vehicle. Why pay for something that has a recall. If your going to reimburse me anyway! I will like to keep my 500+ and not wait for GM to pay me back. Plus they want to pay a diagnostic fee when I told them what the problem is.
