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.

My 2007 Chevrolet Trailblazer had low beam headlights not working when I turn them on. I have to drive at night with high beam lights (they work fine) and I am very annoying to other drivers. I had vehicle checked out and fuses and light bulbs appear fine. I understand this is a common occurrence. I need it fixed.

Solid state relay module for low beam - high beam headlights. When driving at night, both low beam headlights went out at the same time. Was able to switch to high beams to continue home, but not without blinding other vehicles. Replaced the solid state relay at a local autozone store. This relay is a single point failure, which an un-experienced driver could have had a possible accident if the person did not know what to do quickly in a calm manner.

I parked my 2007 Chevrolet Trailblazer in my driveway Sunday 6/21/2015. I received a call an hour later from my neighbor that my lights was still on. I always have my lights set that when you get out of the vehicle they go off automatically. Tried to turn off the lights with no luck. I smelled electrical burning coming from the engine area. Found the fuse box in the engine bay and noticed that the hdm module #45 was completely melted. When I took the car to the auto shop, not only did they find that the hdm module #45 was melted, it had ruined the main fuse circuit board from the heat. Luckily this happened during the daylight and not at night, because I wouldn't have had headlights very long with this module being melted. Also this could have easily started a fire in the engine bay with the amount of heat that was coming off of the melted hdm module. This I believe is a safety problem in the Trailblazers and should be recalled.

Fuel gauge read full tank when in fact the tank was empty. I ran out of gas in my driveway. When this occurred my on dash computer went crazy lighting up then turning off, when I put gas in the car and restarted several times the computer seemed to correct itself. Filling the tank the gauge read empty and remained that way for several days. The gauge operates intermittently. I recently had the fuel pump replaced after failure. The pump was replaced prior to this incident. I have scheduled the gauge repair with my dealer.

I don't have exact date I bought my vehicle it is just an estimate. But issue has happened twice now. Also don't have VIN with me but can get it if needed. I bought my vehicle about 2 years ago. When I bought it the passenger window regulator went out. Lamb's Chevrolet in onida, sd replaced it. Now a few months ago the passenger regulator went out again. They told me well they only have a 1 year warranty on them. Warranty or not it should have not gone out within a couple of years. I am fighting with them on paying for it. Is there any other complaints or recalls on window regulators with the Chevy Trailblazers? I shouldn't have to be replacing this every couple of years. Also they have one excuse after another why it could have gone out while all in all they probably put in a defective or refurbished one which dealer these days are famous for and charging customers full price.

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.

Every couple months the alternator goes out I am almost to the limit on my warranty returns.the first time it went out it wasn't charging then several times after that it went out was over charging and in doing so damaged my battery so I had to pay to replace it also. I have had nothing but problems with this car and is becoming a money pit.

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.

Inaccurate fuel level reading. In November, my fuel gauge and driver information center began to spontaneously read erratically and would not accurately show me how much gas I had. Condition has rapidly progressed to where the fuel gauge almost constantly reads empty, low fuel light is illuminated and fuel level low is displayed in the dic. In researching this issue, I found service bulletin no. 10054B which states it is a premature wearing of the fuel sensor and I should have received a mailed notice from GM regarding this known issue. I have not received any such notice. There are no recalls associated with my VIN and my warranty has now expired so there will not be "vehicle eligibility" for the dealer to confirm through the "applicable warranties section in the global warranty management system." This issue is bigger than publicly acknowledged by GM and needs to be a full recall, not a 50/50 shared responsibility with the customer when GM acknowledges the issue is due to a faulty part that prematurely wears and causes the malfunction. Also, the entire fuel pump including the sending unit and fuel level sensor needs to be replaced, not just the fuel level sensor.

The contact owns a 2007 Chevrolet Trailblazer. While driving at a low speed, both outside mirrors moved independently and the seat heater stopped working. The vehicle was taken to a dealer. The technician diagnosed that the front driver side door module needed to be reset. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer who diagnosed that the mirror actuators and the heated seat elements needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,363.

After the recall of 12180 and repairing the 1st problem with the door my driver's side window only works intermittently. Dealer tells me it's 'not related' to that recall and I have to pay to repair this myself. I don't have the money to pay for another problem on this 2007 pos that GM pumped out. What is this.. the 4th recall" I've had to pay out of my pocket each and every time to get these fixed and it's hell getting my money back from the dealer! now as unlucky as I am, I ended up with 2 of these 2007 GM vehicles, the other an Envoy. Now the Envoy went in for the previous recall #12180 and now also received the paperwork to go in and get repaired under the new recall #14309; why is my Trailblazer not included in this recall?? I still have a driver's door window that only works sporadically, how can the dealer tell me that that's a separate problem when everything I'm reading right now is saying the window problem is inclusive?" I need GM to be responsible and fix this window problem/door motor problem.

The contact owns a 2007 Chevrolet Trailblazer. While driving approximately 45-50 mph, the contact adjusted the front driver seat and lost all electricity to the vehicle, including the lights, power locks, and power windows. The contact could not exit the vehicle. Someone had to open the door from the outside. When the vehicle was restarted, all the electricity returned except the led lights on the steering wheel. The contact believed the failures were similar to those listed in NHTSA campaign number: 14V404000 (visibility). The manufacturer was not made aware of the failure. The failure mileage was 140,000.

The side view mirrors reset when you use the remote the unlock the car. They are preset for driver 1 & 2 and which ever remote unlocks the car the mirrors will re-align themselves sometimes moving around for 60 seconds or more. After all the movement they are not aligned for driver 1 or 2. it's a pain to have to realign both mirrors every time you start the car. I have positioned the mirrors where I want them, push the button to set them, wait for two beeps, and next time I start the car, they are randomly moving again. I have been to the dealer twice to have it fixed and the mirrors seem to be ok for a week or so then start with the random repositioning again. I am afraid the motors in the mirrors will burn out.

My master window switch caught fire on 9/27/14. I woke up that morning to find that my window did not work while driving my daughter to school. Then all of sudden there was a smell of something burning on my side of the car. I immediately stopped the car and noticed smoke coming out of the door panel. I took out the switch and it was burned. It also burned some of the material inside of the door. Then all of sudden while I was sitting on the side of the road. The window started going up and down randomly with the smoke coming out of it. I took it my fathers house where he disconnected the module. The window was half down. It was 45 degrees that morning. I paid someone to put the window back up with a price of $150 due to extremely cold weather and having a 2 year old. I went to crew cheverolet to have this repaired when they said that all 2005-2007 master door switch was on recall due to electrical issues that may cause the switch to catch fire. When they looked up my VIN they told me that my truck was not covered. My vehicle is a 2007 and im not sure why my vehicle is not covered. If this is a known issue, then I believe I should get a new part due to a manufacturing error. They told me I had to pay $405 for the part and programming but could not guarantee that my motor for my window was not damaged as well. I contacted GM myself and they said there is a recall on 2005-2007 Chevy Trailblazer but my VIN was not included. I was told there was a recall for Chevy Trailblazer in my state just not my vehicle even though it is a 2007. My daughter and I could have been seriously injured.
