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.

2006 Chevy Trailblazer fuel gauge was near empty with the warning light on. Went to fill it up and after starting the car, the fuel gauge would stay pinned to empty and the light stayed on. Vehicle has around 52K miles on it.

At about 45K miles my 2006 Chevy Trailblazer gas gauge has started to malfunction. I have read up on this issue and it seems to be a very common problem with GM SUVS and trucks. The cost of fixing this is usually between $600-$1200 dollars. How can GM sit around and let thousands of customers go through this (all happening around 50K miles) without doing a recall?

2006 Chevy Trailblazer. Fuel gauge does not function properly. GM is aware of the issue but has not issued a recall. When fill up vehicle it reads empty at first after using some gas it registers (in beginning). Now it barely works at all. I have to use the trip odometer to measure approx gas remaining.

I have a 2006 Chevrolet Trailblazer. Every time I fill up with gas, the gas gauge fluctuates and the empty light stays on. I have searched the internet and there are literally hundreds of people with this problem. My Trailblazer has about 75,000 miles and it and has been having this problem for about a month. GM needs to fix these fuel gauges, etc. Since it only happens when the car is out of warranty! they are aware of the problem and choose to do nothing! please help the consumers!

Fuel gauge has stopped working completely. I was advised it was due T too much sulfur in the gas however feel it's poorly protected wires. If this has voltage to it and it is exposed is it a fire hazard?

The gas gauge on my 2006 Chevrolet Trailblazer will not work. Without the fuel gauge, it is possible for me to run out of gas at an inappropriate time and cause an accident. Nothing has been done to properly repair the vehicle since the cost is over $800 for a three year old car.

The contact owns a 2006 Chevrolet Trailblazer. Whenever fuel was added to the fuel tank, the "empty fuel" indicator would appear on the fuel gauge. The failure occurred at any fuel level capacity and without warning. The vehicle was taken to an authorized dealer for inspection and they stated that the sending unit failed. Currently, the vehicle is being repaired. The failure mileage was 32,900 and current mileage was 33,493.

On my 2006 Chevrolet Trailblazer, the fuel gauge is now stuck on empty, even after a tank fill-up. There are numerous Trailblazer owners who have posted identical issues on online blogs. The dealership will charge $800 for the repair, which includes dropping the fuel tank. With so many instances of this, GM should issue a recall. If Trailblazer owners with stuck fuel gauges are not diligent on their fuel usage and don't have the means to pay $800 for a repair, they could end up stuck somewhere, out of gas which is a safety/liability issue in my view.

Fuel gauge will not work correctly and is on empty even though it was full of gasoline. The gauge is not working now at all and use tripometer to monitor mileage. Why, because the dealership wants over $900 to repair and I don't have the money. How many complaints does your office need to receive before a recall is done by the manufacturer? this is dangerous and very expensive and there is no reason a car with 40,000 miles on it to have this happen.

Fuel gauge read empty after filling up the gas tank. Continued to read empty while driving. Then it reads full then back to 1/2 tank. It reads all over the place. So now I have to go by mileage instead of the fuel gauge. My mileage is at 58,000 miles on a 2006 Chevy Trailblazer. Please look into this!!!! there is many many complaints about this same thing happening. Thank you.

The contact owns a 2006 Chevrolet Trailblazer. While driving 10 mph, the contact noticed smoke coming from the driver's side door panel. He pulled over and turned off the vehicle, which caused it to stop smoking. A mechanic stated that the control fuse box caught fire. The contact took his vehicle to the dealer, but they did not have the necessary parts for the repair. In addition, the contact was experiencing fuel gauge issues. When he filled up the vehicle with gasoline, the gauge indicated that it was empty. The failure mileage was 47,500. Updated 07/28/09 updated 07/30/09.

My 2006 Trailblazer is out of warranty and the fuel reads empty when you fill it up, I have seen numerous amount of Trailblazers with this same problem. Why does GM not stand behind it, its truly a defect to have so many with the same problem.

  • 65,000 miles
Around 65,000 miles, my 2006 Chevrolet Trailblazer gas gauge suddenly stopped working, only reading as empty and turning on the yellow gas light. This also caused my check engine light to turn on. Upon taking my car for inspection, my car was failed, because the check engine light was due to a bad fuel sensor in my car and the charge to have it repaired is around $900. Upon doing research about this part I found that many other people have had this exact problem around the same mileage as when my problem began. Due to this problem I must now track my mileage in order to know when to fill up, and because I cannot afford the repairs, I cannot pass my state inspection. I feel this problem should be issued as a recall by GM.
