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.

The speedometer in my car started not working a week ago.. it would say I was going 70 and in reality I was only going 55. Now it starts out at 110mph when I start driving....making it really difficult to know how fast/slow I am going. I have read many articles of this happening with this make and model of vehicle.

The instrument cluster went out.I am not sure how fast I am going or how much fuel I have. From everything I have read on line this is very common. I don't understand why GM has not issued a recall.

Letter from senator durbin on behalf of constituent re GM recalls. 2005 Chevrolet Trailblazer. The consumer stated she inquired on several occasions about a recall, regarding the malfunction of the speedometer, gas gauge ad oil gauge. All three of them stopped working.

The fuel gauge malfunctions after filling tank - it reads empty immediately and intermittently thereafter at any fuel level. It makes it difficult for traveling any long distance as you are not quite sure how much fuel is available or if it will shut down on me during a difficult situation. We have contacted GM and they want to charge me to check it and this has been reported as a problem for multiple models to GM. This is very scary as I travel long distances to and from work each day - I feel that this puts me in harms way. I don't believe that I should pay to a defective part that GM knows about but doesn't acknowledge.

My speedometer has stopped working in my car an I don't know how fast the car is traveling, done a research online an there are thousand people with the same probably as mine with the exact same make and model of car as I have. Something needs to be done cause Chevrolet want $500 to replace the speedometer an that is not right.

The speedometer stopped working along with other controls on the gauge cluster. It seems that there are many people that have had the same issue with this in GM vehicles so I am curious as to why this has yet to be recalled. Most people do not have $500+ laying around to get this fixed.

Driving on the highway to the shore my speedometer increased to 95 mph. When we parked it was stuck on 10. Since then it has happened many times. When I park I have to check what it stops at. Sometimes, its 10, 20, 30, etc. I have tried disconnecting the negative battery cable and that helps as a temp fix. My dealer says there is no recall, but I saw online a class action suit against GM, but not for Trailblazers. This is a GM issue and I don't have the money to get it fixed. Updated 03/11/14

Bought this vehicle used in Oct 2010. Not long thereafter, noticed the speedometer wouldn't work all the time - normally it works when I first start driving but when the vehicle warms up, it stops working all together. I think it's a safety issue if you do not know how fast you are going. The cruise control also doesn't work once in a while. Most of the time it does, but occasionally I can't get it to go on at all.

My speedometer quit working one day, and hasn't worked since. While driving it will say I'm going the speed limit and all of a sudden its drops to 0 mph, or say I'm driving 30 mph. My speedometer is never accurate. I went had it checked with the Chevrolet dealer ship and they stated I need a new speed instrument cluster and it would cost me $518 just for the part, not including the labor.

Speedometer/instrument cluster have failed/stopped working. The gauge began ticking while being operated; showing increased, but not accurate speed. Now the gauge stays at 180 mph and no longer functions.

In the beginning the speedometer would go all the way to highest speed immediately upon cranking vehicle. After a few months or quit working all together. The gas gage quit working a few months after that. Then again a few months later all other gauges quit working except RPM gage. That is only functioning gage on instrument panel.

Speedometer failure. Speed presented by gauge was incredibly inaccurate. Rate of speed was 20-30 mph faster. Finally a total "lock-up" of instrument. At a stand still gauge reported 60mph. This has been reported to GM they refuse to recall these vehicles. Refused to repair. Further research showed thousands of reports of failures of speedometers. How many people have died and or crashed because rate of speed was inaccurate??
