Last night I filled my tank up; originally the indicator was on the last line before empty. When I turned my car on after filling the car up completely, the indicator on the fuel gauge went below the empty symbol and the low fuel light came on. I drove the car home and continued to check it through the evening. The tank read empty and the low fuel light was on every time I checked it, but no other lights came on. This morning the indicator was still below the empty symbol, the low fuel light was on, and now the check engine light came on. While driving to work the indicator fluctuated between full and empty. At lunch, 4 hours later, when I turned the car on the indicator was at full. However, after driving 2 miles, it went down completely to empty and the low fuel light can on again. After doing research on the internet this morning I found out that this problem was most likely a fuel sensor problem and that there were many other complaints. All complaints having a fuel gauge problem involved 2005 or 2006 Chevy Trailblazers that have reached mileage of 44,000-53,000 miles. When I called the Chevy dealership where I bought the car I was told that I was correct, that this was most likely a fuel sensor problem. I was told that this was not a problem that Trailblazers have, it was a problem that all new cars have, because there are so many electronic components in new cars and that they fail. It would cost a minimum $800-900 to fix. My car is barely 3 yrs old (2006 model bought used with 10,000 miles in June 06) and has 51,900 miles on it.

Fuel gauge reads empty and/ or sends random levels after refueling.

Filled fuel tank approx. 1 month ago and fuel gauge started fluctuating. Shows empty and light remains on 90% of the time. It has never worked properly since that time. Went to Chevrolet dealer where purchased and was told there is no service bulletin showing a problem. Stated fuel tank sending unit probably bad. Fuel tank has to be removed. Price ranges for repair between $800 and $1100. Have decided not to get fixed due to cost and research showing this is a very common problem Chevrolet is having. Temporarily correcting problem by filling fuel tank every 250 miles.

I just bought my used 2006 Chevy Trailblazer a few months ago, and almost immediately began having problems with my fuel gauge. Everytime I would fill up, the gauge would malfunction and read empty. The low fuel light would come on and the chime would alert for low fuel. Eventually, after driving several miles, the gauge would begin working correctly. However, the problem has gotten increasingly worse over the past few months. Sometimes the gauge would not correct itself at all, and often the check engine light would also come on. More recently the fuel gauge rarely corrects itself and I have to constantly keep track of my mileage and "guess" when I need a fill up. Upon researching this problem online, I've discovered that there are an alarmingly large number of GM owners who have experienced this same problem! supposedly, the repair requires a new fuel pump, sensor, etc. Of course, since the tank has to be dropped, this means a high labor rate as well. Most people report a cost of approx $800 to correct this problem! luckily, my vehicle is still under manufacturer warranty, but with the outrageous number of owners with this issue, GM should be required to step up and take responsibility! a recall definitely seems to be in order!

Earlier this year on complaint #10225267, I reported that our 2006 Trailblazer gas gage stop working and the engine light came on. Our dealer said they fixed it. A few months later thee engine light came on again, took it back to the dealership, they said they couldn't find anything wrong and erased the error. This week in again the engine light came on and the Blazer is at the dealership again. When is GM/Chevrolet going to fix this problem. I know for every complaint on this site there are many silent Trailblazer owners who are going through these some fuel gage and engine light problems.

After having my vehicle for one year, the fuel gauge suddenly became erratic. When fuel was near empty, it would read "full" or "half full". the engine repair light would go on and off inconsistently during the same time. I thought it might be the quality of gasoline, but trying different brands did not help. Within a few months, no matter how much fuel was in my tank, the gauge would read "E" for empty, with the needle never moving from E. the yellow light and "dinging" sound ring a lot letting me know I am supposed to be out of fuel, but am not. This is the case even with a full tank of gas. It is a safety hazard because I have to reset my tripometer when filling up on a new tank of gas, so I know about 250 miles, I need to fill up again. If I don't do this, I could run out of gas, cause a crash, or a fatal accident since my gauge always reads empty. I have read many blog and complaints about the fuel gauge on the Trailblazer and other Chevrolet vehicles. Mine is a 2006 with currently less than 24,000 miles on it, and at the time of occurrence, about $21,000 miles. I understand the repair and parts will be about $800. For such a young vehicle with low mileage, how can this be? there needs to me a recall with so many people having the same problem.

I have seen the news when the 5 high school seniors in New York, May 2008 I believe, were killed and then just 3-4 weeks ago, Oct 2008, the news reported a young mother was killed out West. Both accidents involved a front end collision and both where mid-size GM SUVS (Chevrolet Trailblazer, GMC Envoy, Buick rainer). Both accidents resulted in fires and deaths. The news reported the fire was to intense to attempt a rescue in the New York case. In the case out West, the young mother's two children were rescued, but to the intense fire she was unable to be rescued. I would like to know if there have been any other complaints or comments on this or if it was ever reported to this Agency. I have a 2006 Chevrolet Trailblazer as my main vehicle and would not want it to have some unknown defect that may cause my or any member of my family a loss of life. Thank you for any information you can provide.

Fuel sensor is out on my 2006 Chevrolet Trailblazer. Common problem. Gas gauge always reads empty--even after I fill up.

I have a 2006 Chevy Trailblazer. At about 40,000 miles, my gas gauge began not resetting completely when filling up and began working sporadically. A couple of weeks later, it stopped working altogether. I have read many message boards online and it seems that there is an issue with the fuel sensors on the 2006 Trailblazers and everyone describes a similar experience as mine. My vehicle is out of warranty now and I can not afford 800 dollars to fix it. I have to utilize my trip odometer to know when to fill up and simply have to guess about my gas mileage. To date, I have run out of gas once because of this faulty sensor, making me late to work. If this is a recurrent issue with 2006 Trailblazers, a recall needs to be issued!

The contact owns a 2006 Chevrolet Trailblazer. At 40,000 miles, the fuel gauge sensor stopped working. The fuel gauge needle does not move and indicates that fuel is present, when in reality, there is none. There is no recall relating to this failure. The dealer stated that this was a common failure with this type of vehicle. The failure caused her to run out of gasoline on the highway. The failure mileage was 44,000.

Friday evening I filled our Blazer up with unleaded gas and as I drove home I notice the gas gage marked empty and the low fuel light came on, I stopped to make sure the gas cap was on correctly and continued home. A mile down the road, a engine outline came on my instrument panel. Parked the Blazer until Monday morning, when I drove it into town to our Chevrolet dealership. As I drove into town the gas gage started on full and worked it way down to empty. Now my Blazer is at the dealership and I fine that others have had the some problem. So I sit and wait.

2006 Trailblazer, 26560 in mileage. After filling vehicle up with gas, low fuel light came on & it kept dinging!!!! the tank was full. Dealer states that they need to drop the tank & keep the vehicle for at least a day to figure out what the problem is. I'm afraid how much this may cost. Have viewed other complaints of this same problem with 2006 models.

- Rochester, NY, USA

The contact owns a 2006 Chevrolet Trailblazer. The contact stated that the fuel gauge would drop to empty when it was at half a tank. The vehicle was taken to the dealer and they stated that the fuel module was enlarged and needed to be replaced. The failure and current mileages were 61,000. Updated 03-05-08
