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.

My gas gauge has stayed on empty for a month or so with the gas light on. I have not had the money to fix it and I put gas in it the night before the incident happened. I was driving home from a family members house a few blocks away from my house and my 2005 Trailblazer died and everything locked up on me. The brakes would not work what so ever. And I just had brand new brakes put on a couple months ago and my steering wheel locked up. My vehicle would not stop. It kept going. I am so happy that I didn't have my three small children with me. It took me three turns onto three different streets before it finally stopped. It was very hard to turn. And my back wheels were making a horrible noise and smelled really bad when I got out. I always keep a gas can in the back in case I ever run out of gas due to the gauge not working. And mind you I have only had this vehicle a year. GM should have to pay to get this fixed. This is very dangerous. Thankfully someone was watching over me and there was no other cars headed toward me. It was on a main roads that has a 45 mile an hour speed limit. I will never buy a Chevy again.

Gas gauge was reading inaccurately resulting in car stall. Also, speedometer is not functioning correctly - will start out anywhere from 5 mph to 45 mpg over from standstill.

My 2005 trail Blazer instrument cluster is going out it started with the oil gauge and now its the gas gauge, I was also told by the dealership that eventually my speedometer would stop working, it is extremely dangerous because I am not aware of how much gas is in the vehicle or if the oil pressure is having an issue. This repair at the dealership is costly.

On or about November 12, 2010 the vehicle owner had the instrument panel replaced. Shortly after replacing the instrument panel at a cost of approximately $550 the gas sensor stopped working. The owner complained to the Chevy service department but was told that this was a separate issue and not caused by the replacement of the instrument panel. The owner checked for recalls on the internet but found more complaints for the same issue but no manufacture recall or data on either the instrument panel or gas senor/gauge. Since the gas sensor/gauge/fuel level indicator does not work the vehicle owners have run out of gas at least 3 separate times. 1). a Friday night at 10:00 P.M. on a dark winding road; 2). On a very busy 4-lane thorough fare both vehicle owners and a passenger ran out of gas at a stop light; 3). Most recently was approximately 3-weeks ago. There's no way to know when the gas tank is full or running low on fuel because the "low gas" fuel light stays on most of the time or when the owners do fill-up the tank the gas gauge remains "E". the owners were quoted the cost of repair would be upwards of $500+.

Nearly eight months after the purchase of the Chevy Trailblazer (April 2008) and while traveling from Tennessee to New York the instrument panel that controls the RPM, odometer, speed, fuel gauge, oil level, temperature, etc. Completely stopped working. While traveling in the state of New York on I-90 E the driver had no indication of the vehicle speed. When shifting from the left passing lane to the nearest middle lane a NY state trooper clocked the vehicle speed at approximately 90+ miles per hour. The driver was sighted with a speeding ticket during the thanksgiving holiday weekend. The vehicle owner had the instrument panel replaced at a cost of more than $500. However, soon after the instrument panel was replaced the gas sensor stopped working. The owner complained to the Chevy service department but was told that this was a separate issue and not caused by the replacement of the instrument panel. The owner checked for recalls on the internet but found more complaints of the same and no recall information. Since the gas sensor/gauge/fuel level indicator does not work the vehicle owners have run out of gas at least 3 separate times. Once on a Friday night at 10:00 P.M. on a dark winding road. Another time on a very busy 4-lane thorough fare the vehicle owners with a passenger ran out of gas at a stop light. Most recently was approximately 3-weeks ago. The vehicle owners have purchased at least 3 new gas cans since we cannot tell with the vehicle is full of gas or not. When the gas tank is filled up there's no way of knowing and the owners cannot tell when the vehicle is running low on fuel since the "low gas" fuel light stays on most of the time or the gas gauge rarely moves passed "E". the owners were quoted that the cost to repair would be upwards of $500+.

1) fuel gauge indicator shows an empty reading despite just being filled. After driving for 40-50 miles gauge will show about a quarter of a tank for a short time and then go back to empty. When problem first started the gauge was all over the dial. 2) speedometer erratically will show a speed at a greater speed than actually traveling. Recently showed going 110mph despite traveling along with traffic flow of approximately 65 mph on major interstate highway.

The car states I am going 50 mph less than my actual speed. This is a safety concern for me. If it wasn't for my gps I wouldn't know my actual speed. I have read several others complain about the same problem online. Please recall this.

Speedometer jumps all over the place. Everyday now it will jump forward. When I stop at a stop light it will stick at some mph not going to zero. Then when I take off it will start where it halted at. So if it stops at 35mph then when I get to 55 per my gps the speedometer will show I'm going 90. Sometimes I'm going 120mph it's all over the place and it happens everyday now. I was reading on-line and see this is an on going problem with Trailblazers.

Speedometer jumps to different speeds. When you shut off the truck it will stay stuck 110mph, or when you restart the car it will just jump down a little 100mph. Other Chevy models have had recalls on the same problem but not Chevy Trailblazer? why

Trailblazer 6-cyl

My speedometer began to work improperly. Sometimes it would not go all the way back to zero when the ignition was switched off, or it would be functioning properly and then for no apparent reason the needle would go all the way around and end up pointing at the park, neutral, reverse area at the bottom of the speedometer. Now the speedometer does not work at all and the tachometer has started to work intermittently. It is doing the same thing that the speedometer was doing. Right now the vehicle is off but the tachometer needle is on 3. I just had the fuel sensor gauge replaced under Chevrolet's "special policy" because it had ceased working as well. I have serious reservations about the integrity of the other gauges because while they appear to be working I do not know. I contacted cheverolet and was told that while other makes and models had been recalled mine had not. When I inquired as to whether the components for my instrument cluster came from the same supplier as that of the recalled vehicles I was told that they would not disclose that information to me because it was confidential. They did say they had other complaints similar to mine but at this time they were not offering any assistance to consumers and did not know if or when they ever would. I was told that due to the age of my vehicle (a 2005) that I could expect certain repairs. I do expect certain repairs however a total failure of the instrument cluster, that has been documented on my make and model as well as other Chevrolet, is not one of them. It is frustrating and disheartening to me that while Chevrolet is aware of the problem they knowingly disregard the concerns of their customers, especially as the malfunction of a fuel gauge, speedometer or any other instrument panel component could have serious consequences.

The speedometer does not reset itself when the vehicle slows or stops. Instead, it resumes from a higher speed. For example, if you are traveling at 45mph and stop at a stoplight the speedometer may drop to 40mph upon stopping. Then when you resume traveling it starts from 40 instead of 0 so the speedometer shows you are traveling 60 when you are going 20, 70 when you are going 30 etc. When you stop again it will come to rest at an even higher speed, until eventually the needle shows over 120 mph when the vehicle is sitting still! I have done some investigation on line and this appears to be a fairly common complaint from fellow owners. General Motors apparently dopes not consider this a safety issue and as such will not pay for the repair which is $500 or more. I'm not sure how not knowing you rate of travel is not a safety concern for them, but it certainly is to me.

1.) nothing I can think of that I did caused the problem to start. 2.) the speedometer in my 2005 Trailblazer simply does not tell the correct speed. Nearly ever time I drive the tack will either stay at 0 or will go up to and beyond 120 mph. I have resorted to using my gps to tell my speed, but it is a large inconvenience to me and may others that I have found online. 3.) I have just begun to research the problem so I have not done anything to fix the issue.

The speedometer on my instrument panel cluster malfunctioned. Problems included the needle sticking in one place, not moving down when decelerating, and even spinning to the "6 O'clock" position below the gauge. I called Chevrolet to find out information and they were not able to offer me any help or reimbursement assistance.
