Failure to the fuel gauge sensor. Started acting erratically, showing incorrect volume in gas tank, but was sometimes right. Total failure came about 6 weeks after initial symptoms. Causes engine light to activate as well. When I called the dealer and a garage, both were familiar with the problem and said it was common on GM vehicles.

Gas tank gauge has not working properly starting around 40K miles. Warning light and noise goes off randomly. Have to manually calculate mileage now. Too expensive to fix. Now check engine light is on and the vehicle rpms drop down low when I'm at a stop sign. Luckily, it hasn't died yet but I will have to take in.

Around 60,000 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.

- Easton, PA, USA

At 57,000 miles, fuel gauge stopped working. Consistently shows empty, even when fuel tank is full. Causes fuel light to remain on and causes check engine light to go on occasionally.

Have noticed in the news two accidents in which a GM SUV series (Trailblazer/ Envoy/rainer) have caught fire after a front end impact. The five young women in New York state and then a story on cnn in which a woman was trapped and burned alive out West. Both stories were last year. I ask if there have been any other complaints of engine fire after front end collisions with this series of SUV because I drive one as my family car and would like to ensure it is safe. Thank you for any information.

My 2006 trail Blazer has approx. 60,000 miles. I have had to replace an injector. The heater fan motor is now not working and the fuel level sensor does not work, the lighter does not work and keeps blowing fuses if you try to use it. I have replaced both brake lights as well.

- Florence , KY, USA

2006 Chevy Trailblazer, fuel level sensorlocatedin the gas tank has failed@roughly 56,600 miles. Found numerous complaints of the same on the internet. Given the millions of dollars given to GM they should be directed to deal with known short comings in their product.

I hit a bump one day and the interior light popped on for a second and then went off. I eventually realized the rear door was not latching at all, I tinkered with it, tried some wd-40, it does work intermittently, but is getting to the point where its not latching the majority of the time. The 3 bolts holding the locking mechanism and the point where the lock with latch do show signs of corrosion. It appears the 2003 Trailblazers had this same issue and eventually there was a recall. At 38,000 miles I also had the fuel gauge issue and the fuel sending unit is bad.

Fuel gauge is erratic and no longer accurately measures the tank contents.

- Hampton, IA, USA

Fuel gauge is not working correctly. Says empty (with the light on right after a fill-up) and fluctuates between empty and full between fills.

- Lincoln, NE, USA

No warning-- filled up gas tank with 19 gallons- no warning light and not below orange line-- warning light comes on and gas gauge reads empty; then reads erratically-- have to drive and get gas based on trip odometer; took to repair shop told was ascending unit and fuel pump will cost anywhere from $700 to $1,100 to repair; apparently this happens with 2006 Trailblazers between 40,000 & 50,000 miles (ours is at 57,000) --told will happen again at 100,000 miles-- have not had repaired waiting until can come up with to fix or completely quits working.

- Lake Saint Louis, MO, USA

Gas gauge is on empty all the time regardless of how much gas is in the tank. Had it fixed at the dealer at 25,000 miles now it is happening again at 50,000.

The contact owns a 2006 Chevrolet Trailblazer. After filling up the vehicle with fuel, the contact noticed that the fuel gauge failed and displayed that the tank was empty. The "low fuel" and check engine indicators illuminated on the instrument panel. Due to the failure, the contact must always write down the amount of gas he purchases in order to estimate when the vehicle needs to be refueled. The dealer stated that the fuel gauge sensor failed and would cost $400 to repair. The vehicle has not been repaired or inspected by a technician. The manufacturer stated that the failure was not covered under warranty; therefore, no compensation would be provided. The failure mileage was 48,000 and current mileage was 49,600.

I bought my 2006 Chevy Trailblazer in January 2008. Right now, it has about 44,000 miles on it. Two month ago, the fuel gauge completely stopped working. It always displays that the tank is totally empty and the fuel light is on, no matter if I just filled up the tank. I did research on the internet and have seen that this is a very widespread defect that has affected a large number of people. The mechanic I took the truck to says that it will be about $800 to fix...that is unacceptable. I want Chevy to issue a recall on this vehicle and fix the defect that obviously is their fault. It isn't a coincidence that this same problem is happening to so many other people.

Gas gauge stopped working correctly at 38K miles. Fuel sending unit is bad.

I recently bought a 2006 Chevy Trailblazer from a local used car lot. Two months after my fuel level gauge went out I searched to see if anyone was having the same problem and how to fix it I made many call to GM to see if there was a recall on this part because so many was having the same problem throughout America my mother ask to drive my car I have not fixed the problem I explain to my mother the problem with the car you can't tell how much gas is in your car anyway long story short she ran out of gas on the interstate and pull on the wrong side a car smash into her from the back this is why GM is asking for money and non american car makers is singing we need to make GM recall these half made cars could you please put a mandatory recall on the 2000's Chevy Trailblazers thank you in advance.

2006 Trailblazer, gas gauge light stays on no matter how much gas is in the tank. Seems like an on going issue with Chevy Trailblazers between 30K - 60K miles, cost $600 - $800 to repair, should be something covered by Chevy if there are so many complaints regarding this issue. I use the trip odometer, however, I have ran out of gas, which could have lead to varies dangerous/life threatening events. Chevy should recall this, before they face a major lawsuit based off something going terribly wrong because of a defective product.
