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 check engine light comes on&off a lot right after fueling, I took it to the GMC dealership&had the camshaft replaced because it kept cutting off every time I turned a curve.I tried to show or tell them about this GMC recall letter I got on my 2005 Chevrolet Trailblazer, but they said that it didn't apply because of the mileage&I told them the car is not 10yrs old& the paper is saying 10yrs/120,00 miles& for me to take it to the dealership so that the manger can send my bill & receipt in for reimbursement they wouldn't do it.I guess because I'm a woman.driving to work on the interstate the car shut completely off. The car was still moving when all of a sudden all the lights and gauge's lit up and the car cut off. It did not lock up so I was able to steer it from the middle lane of a three lane interstate highway to the grass on the side without getting killed or hurting someone else.I had just filled it up with gas with a quarter of a tank from the full line. Once I got the car to a complete stop and thanking god that this was not tragic, I put the car in park and waited a few minutes before starting it back up. It started back up as if nothing had happened. I took it to auto zone to get a free diagnostic check&it showed that nothing was wrong. A few weeks later after I would cut the car off the air conditioning would not stop&the engine light constantly comes on every other time I hit the brakes. I had to keep taking out fuse #35 to get it to stop even after the car was cut off just so the battery won't run down. Took it to the dealership and was charged an arm&leg to get it fixed. I showed them the recall letter again and they said it was too late for them or myself to do anything about it. I have all of my receipts & the letter from GMC about the sure my vehicle fits in there somewhere with these problems& truly would like 4 them 2 give my free car.

In 2007 I paid off my vehicle and now became the proud owner of my truck. In 2009, I noticed some problems with my truck. First, the gas gauge would say "F" full, but really it was on "E" empty. Then the mileage gauge " I can be on the expressway going as fast as the other cars, but my car reads 20 mph. This is crazy!!!! I called at 800-number for GMC and was informed that there was no recalls or any others calls for the 2005 Trailblazer, which I knew was a huge lie!!!! I decided to go on line and google the make and model of my car. Wow? guesses what I seen" there were over 41,000 people who have the same problems that I had for their 2005 Trailblazer. Again, the problem with my truck has gotten worst. In 2010, I called again and was informed that their still wasn't any other calls or concerns with my truck and that I should take it to an authorize Chevy dealership. Well, I did... in 2011, I called again.. same script same story!!! I received a letter for a emission test for my car. Well, let me tell you when I took my vehicle up to the emission testing it failed!!!. I got an estimate cost of $ 1900, plus they found 3 additional codes.. well, I got a 2008 Chevy Impala. I went from paying no car note, to $381 a month note. The week of September 4th, 2011.. I receive a letter from Chevrolet addressing the issues with the 2005 Chevy Trailblazers, and offering 50% on repairs for the same problems that I have been calling on for 2 years.

Gas gauge malfunctioning, engine light keeps coming on and off. In looking at different web-sites, this is common for this vehicle. I purchased the vehicle on 06/20/2010 and have had several things go wrong in the (8) months that I have owned it.

Trailblazer 6-cyl

  • 84,414 miles
My 2005 Chevy Trailblazer's gauges/panel is not working at all. It reads that the truck is running hot, that I'm going way over the speed limit (when the truck is actually parked), and that I have no gas (after I fill it up). My oil gauge it also out of whack. Please help.
