Own a 2006 Chevrolet trail Blazer. Have run out of gas three times because the gas gauge does not read. The car is full of gas, but the gauge still reads empty. Have run out of gas on main roads and caused traffic jams. Will cost over $1000 to repair the fuel pump.

The issues started about a month ago when I had two unexpected stalls due to empty fuel tank. The needle was indicating that fuel was still available, though near empty. Then finally the mystery was solved on November 15 when the fuel level sender finally failed. I filled the tank normally but when I started the vehicle, the needle stayed at empty, low fuel light came on and low was displayed in the range speedo display. After a quick search, I realized the source of all my problems. Another faulty trailblazer fuel level sender. I purchased the part from my local dealership and replaced my part (no need to replace the entire pump assembly). However at close inspection, I see that GM has changed the design of the metal "wipers" the slide along the resistor segments on the sender. Clearly they realized at some point that the design needed improvement. The new sender's wipers are fewer in number, but are wider and appear to made from slightly thicker metal. All considered, the new design is more robust and I anticipate longer life. Unfortunately, as I read all the complaints, we all share the same issue and have paid various amounts to get the issue resolved. I am fortunate that it only cost me the part and one entire evening. Others are not so lucky, they pay whatever the dealership needs to fix the faulty part. This is clearly widespread, early life failure and should be addressed by GM with compensation for a faulty and now improved design.

The fuel gauge on our 2006 Chevy trailblazer has failed along with the check engine light coming on resulting from numerous codes. The entire fuel pump/filter/sending unit has to be replaced (a $300 part) and the vehicle won't pass and inspection without it. GM needs to recall this vehicle for this problem and refund owners who have spent money fixing the problem if they want to continue to stay in business.

I bought a 2006 Chevy trailblazer in January 2009. Once I reached about 40,000 miles, I stopped to get gas and after I filled up, my light indicating I needed gas came on (it was not on prior to getting gas). I knew I had gas so I kept driving; my engine light then came on. Both of them have now been on for over a year. In order to replace the sensor, I need a $500 part! I keep track of my mileage and fill up every 250 miles. Last week, my car just shut down, while traveling down a hill with my two children, I was apparently out of gas. We nearly crashed into multiple vehicles! I have seen that there are hundreds of the same problems in this vehicle and I believe it should definitely be recalled. I learned what can happen when someone thinks there is gas in the tank and there is not... I had to turn on my 4 ways and honk the horn because I had no brakes, no steering, etc... I had to use my emergency brake to stop and had to tell my 10 year old to hang on and cover his 2 year old brother!!! the fact that Chevy has been made aware of this and done nothing makes me sick! my entire family was in danger... thank you!

Fuel sensor and/or sending unit installed in the 2006 Chevrolet Trailblazer ext is defective. Initially, the needle bobbles between the actual fuel level and empty but eventually sits at the empty reading despite the actual fuel level. The defect, which should be recalled, could result in the vehicle running out of fuel, stalling out and possible rear ending by another vehicle. I have been told by several dealerships and it is evident in several blogs that the average cost to fix the problem is $800. It is also clearly a widespread problem as evidenced by several internet blogs and dealership confirmations. Please initiate a recall.

2006 fuel gauge not working trailblazer.

As with many other posters and complainants, I too have an issue with the low fuel light on my 2006 Chevy trailblazer. It will show low fuel even after filling up as well as waiver from full to empty while driving. This nearly became a problem as my family and I were driving on a long stretch of highway in which no gas station was a round for 100 miles. Thankfully the gauge was wrong in telling us it was low as it could have been very bad due to the time of night when we were driving. I have not fixed the problem yet. For now I am judging my gas level based on the odometer reading and estimated gas mileage. Problem began to occur around 43,000 and is now at 48,000 miles.

When I fill my gas tank the fuel gauge goes to empty and stays there, and sometimes goes erratic up and down so you never know how much fuel is in the tank. I am very afraid that by not knowing how much gas is in the tank, it may lead to over filling and causing a fire hazard at the pump by spewing gas all over to running out of gas in a passing lane of a highway possibly causing serious injury to myself or anyone else in my 2006 trailblazer, to injury or death to anyone in their car that may hit me or run into someone else to avoid me. This is an extremely dangerous situation that I see occurs to many, many others with my 2006 GM trailblazer similar models of different years!! at this time I have not gotten to a mechanic on this issue, but seeing on blogs it appears to be the sensing unit and fuel pump.

The contact owns a 2006 Chevrolet Trailblazer ext. After refueling the vehicle, the fuel level gauge dropped from full to empty and would not display an accurate reading of gasoline in the vehicle. The low fuel light would constantly illuminate and the contact stated she would have to refuel the vehicle daily. The vehicle was taken to the dealer who advised the contact that they would have to drop the fuel tank and repair the sensor at her expense. There were no recalls for the failure. The manufacturer was contacted and advised that they were not aware of the failure and would not provide any further assistance. The failure mileage was 56,000.

I have a 2006 Chevrolet Trailblazer ext and since about the 40,000 mark, the gas gauge is not working. It displays that it is on empty all the time. When I took it to the Chevy dealer, they said it would cost over $500 to repair it. This is a safety issue and should be recalled.

Fuel gauge has failed. At any given time, I am uncertain of the amount of fuel in my gas tank. I have contacted the dealer, they said they would diagnose the problem for $99, and the repair could cost $600 - $800. This is an obvious defect and should be replaced by GM as part of a recall. Since I could run out of gas at any time, it is obviously a safety issue.

Chevrolet trailblazers are having problems with fuel gauge not working properly. Chevrolet knows about the problem and they know that lots and lots of their trailblazers are not working properly with the fuel sensors and are charging people $800-$1,000 to fix a problem they should recall. My trailblazer has approximately 76,000 miles and the fuel gauge broke yesterday. This is a concern because you can not tell when you are low in gas. When driving down the interstate, you could cause or be in an accident if your car runs out of gas going down a busy interstate at 70 mph not knowing if you have sufficient fuel or not. GM should recall the trailblazers since so many of the vehicles have had a problem with the gas gauge. Fuel system malfunctions are dangerous.

My 2006 Chevy Trailblazer ext fuel gauge sensor failed at 48000 miles resulting with no way of knowing how much fuel is in the tank which could result in engine stalling and/or rear ended by another or pulling out onto the highway and broad sided.

The air conditioning on my 2006 Chevy Trailblazer ext stopped working. The problem was the blower motor resistor module and resistor module connector. The parts had melted together, causing the wires to become loose at the connection. Apparently this is a common problem with my Chevy model. There are many online postings indicating that the problem could cause a fire. Chevrolet company refused to even look at my vehicle until I paid a $110 diagnostic fee. The service technician immediately knew what the problem was and explained that it was a common problem with my model and the Tahoe. The gas gauge also stopped working recently which I was told by the technician that it too was a common problem. There are numerous complaints on these parts as well as the brake light circuit boards, which also went out on my vehicle. The technician once again said that it was a common problem. These parts seem to be failing shortly after the warranty expires. There are many issues with the electrical system in this vehicle. The problems are hazardous safety issues and are known to the Chevrolet corporation. I was able to find the parts at nearly 80% cheaper than what the dealer wanted to charge me, not including the labor and diagnostic fee. Safety recalls on these parts should be issued.

3 weeks ago, per the fuel guage had 1/4 tank, no 'low fuel' light indicator. However, my vehicle ran out of gas, leaving me to coast to the side of the road on a corner. I was stranded. I have not let the tank get that low since, out of fear the guage was not reading it properly. Last night, I filled the vehicle. Apporximately a mile from the gas station, my check engine light came on & the guage registered empty with the light indicator. During my 10 minute drive it continued to fluctuate between empty & full. I am affraid of the vehicle cutting out again while driving in traffic or manuevering through corners. This is very dangerous.
