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.

The low beam headlamps fail simultaneously. This occurs while driving at night. I have replaced the hdm solid state relay twice, but after a time. 6 months to a year, the failure occurs again. Once the hdm module became to hot to touch upon failing. This last time, the third, the lights may come on again after some time has passed. It is as if the module is short circuiting or overheating leading to a short circuit.

The low fuel gauge indicator remains on even after I fill my fuel tank. The indicator never goes off at anytime.

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.

As of 2011 (while driving on freeways in multiple occasions) I've been having electrical issues such as my fuel level gage would read full and vehicle would shut off cause no gas in tank, air bags sensor would show it on when no one is sitting in the passenger seat, and there are some electrical issues on driver seat controls not working, dash board gages not showing readings while vehicle is in motion (rmp, speedometer, oil, gas).

The speedometer will not work properly. It will be stuck and then it will not display the correct speed while driving. This has been a problem with this car for 2 years. Also the fan control switch stops working at the same rate. Some days it works and some days it won't.

The vehicle was driven to the dealer and the diagnosis was that the ABS sensor, the oxygen sensor, the brake pads, the cluster module and the fuel sender lever had to be replaced. The vehicle was being repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 178,000. The VIN was not available.

The gauge cluster, speakers and occasionally lights stop working at various times, the gauges either register completely maxed out, minimum or somewhere obviously wrong. Example fuel gauge way past full, oil pressure gauge reading 0, charge gauge maxed out tachometer completely off the scale and speedometer inoperable. Rear speakers work sometimes and bulbs in brake lights and tail lights keep blowing out. The gauges are of most concern as the true values of fuel level, oil pressure, battery voltage and engine temp are rarely accurate (or even close). The speed will not operate at times and occasionally if the vehicle is restarted the speedometer will correct itself. All these conditions create safety concerns on some level from running out of gas in a less than desirable location, driving at incorrect speeds, overheating engine without warning or engine problems. Losing a tail light not only creates a safety concern for traffic but creates issues with law enforcement as well. These conditions can happen at any time, driving, parked or idling but the key must be on to power the accessories. Type of driving (city, highway, etc, ) makes no difference.

I have lots of issues with my Trailblazer. Just today my A/C quit blowing. I've had enough so decided to research online. Glad I did because it seems that there really is a problem with these vehicles. First off I my gauges(all of them, including fuel gauge) started to act up. Sometimes they worked and other times they were way off or just hanging. The fuel gauge and speedometer no longer work at all. This all started years ago. I have just lived with it as I don't have the money to fix them. My headlights started going on and off at random about two years ago. Also something I have just lived with as I don't do too much night time driving. Now that my A/C is not blowing I will have to do something. I live in Florida, and am not going to allow my daughter and I to sweat everyday back and forth from work and school to home. This sucks!!! they really needs to recall the whole electrical system for these vehicles. This is a fire hazard due to the connections getting so hot they burn up.

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.
