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.

Fuel gauge always shows empty, not working. No way to know how much gas is in the car. Oil gauge not working.

Fuel gauge was on 1/2 tank. I went to the gas station to fill it up and all of a sudden the gauge meter went to the left and read "empty" and the low fuel light came on even though I had a full tank of gas. I restarted the truck and the fuel gauge meter still read low (less than a 1/4 tank), it eventually returned the to the 1/2 gauge/meter mark. Car was stationery at the gas station at time of the incident, then I eventually drove off at low speed.

Since 2011 I've been having wrong reading of gas levels causing my vehicle to shutoff. Plus my passager air bag displays on when no one is sitting in seat and when someone is sitting in passager seat it occasionally flicker on and off. However I have not had a incident just yet but I'm very concerned and don't feel safe driving with my kids in this vehicle.

My gas gauge reads empty all the time even after a fill up. It never moves. Also I have replaced shocks and struts all the way around the vehical but every time you hit a bump in the road it shakes you from side to side really hard.

I went to the gas station and filled up my tank. I started my car and the gauge was not at the fill line. The gauge just bounced up and down and then went below the empty mark making the chime go off and the car red "fuel is low". this was on a secondary city street.

I purchased this truck brand new off the lot in May 2005. A few years after purchase the gas gauge stopped working, I attempted to search the web for recalls and there weren't any. Eventually it started working again on its own. So I didnt think anything else about it. Around 2009, or maybe later, it happened again. I then found out there was a way to get it replaced for free but it had stipulations. Less than 10 years old and under 100K miles. Well at the time it was 108K-115K miles and I was denied. I must admit I love my vehicle but to this day I have been fighting to get the pump replaced without having to pay for it as it was the companies fault. I calculate my miles based off the "trip" indicator on the dash. I know it seems silly, I mean it would be much easier to just invest, I'm a bit stubborn. So instead, when the thousands of people I know mention buying a car I just tell them dont buy a Chevy, even if they have amazing cars. Truth be told not one family member has a Chevy because of my incident and any new family members well they aren't allowed to have Chevy either. Thanks for listening, I'm sure it wont matter, either way but these blogs and complaint forums make me feel better. (my car was in motion when it stopped working, travelling from one state to another, on a major highway)

Fuel gauge is not working properly. I checked with dealer and the NHTSA website about this issue. The problem is that GM will not honor the service bulletin. According to GM I was mailed out a service notice on my vehicle in 2011 which I never received. # 10041526. I checked with the GMC dealer about this service bulletin and the they told me to bring my vehicle in for repairs. Well the dealer called and told me that my vehicle was out of the parameters for a cost free repair. I bought this vehicle brand new back and 2005 and I have kept up with the repairs and maintenance. The dealership I have this serviced at over the years never did any repairs on this service bulletin. I am a oif army veteran and I can not currently afford this $900 repair. I told customer service at Chevy about this and all they offered was a Chevy loyalty car. Really your kidding me?

Fuel gage is not showing the fuel level, so it looks like its empty all the time automatic air bag passenger sensing system is malfunctioning and on windshield urethane bead may not have adhered to the body in certain areas during the cure process.

Lights go out/dim while driving. No additional electrical items in use-heater, ac, gps, radio, cigarette lighter. Does not appear to be affected or caused by speed, acceleration, deceleration. Fule tank will sometimes register empty while mostly full. Do not notice problem during daylight driving.

I noticed my battery guage quit. Then after starting my truck a few different times, the gas guage read differently. Then my speedometer wduld stick on 100 when I was doing approximatly 60. Then the speedometer would not work at all. There needs to be a recall on it. My friend has a 2005 also and her cluster pannel went out too. Its a $400 repair. This has happened to quite a few 2005 Chevrolet Trailblazers from what ive read online. Come on General Motors. You need to recall these models.

This vehicle was knowingly sold with an existing failure to a warrantied part. The dealership failed to notify us, the prospective buyer about the failed part and has attempted to offer "hush money" to make their responsibility go away. The secondary air injection pump is known to be bad on the vehicle and the dealership refuses to repair it and just as stated offer hush money to make this problem go away. This type of behavior needs to stop and dealerships held responsible for their actions. A document with the information about the problem can be provided if needed to further investigation.

The fuel gauge stopped working in my vehicle and by the time the recall occurred in 2013, my vehicle has more than the limited mileage of 120,000 or less to pay for half the repair cost. The speedometer failed to work at all back in 2009 as well.

Everytime I fill up my truck my gas needle go to empty. Now it's stay on empty.. I had ran out of gas twice. The first time I ran out of gas I was in columbus, Ohio. I had an 1998 Blazer and I had to get an new fuel pump cause the gas gauge was in the fuel pump. Something need to be done about this.
