Seven problems related to ignition have been reported for the 2003 Chevrolet Trailblazer. The most recently reported issues are listed below.
Fuel gauge unreliable/erratic. Fuse gauge will read past full occasionally after filling the tank. After some amount of fuel is consumed the gauge will slowly begin reading within range and eventually as the tank empties it will typically, but not always, begin to read what I assume is a correct amount. It is hit/miss at each ignition turn whether the gauge will read what appears to be correct fuel level. When the issue is occurring, the gauge does not do the ?zero? reset calibration. I have been advised this could be the stepper motor in the gauge cluster (known manufacturer defect that gm refuses to acknowledge for this model vehicle) or the sending unit. This condition is a safety concern because when it does happen, I never know how much fuel I have remaining and I or whoever is driving the vehicle could be left stranded along a desolate highway with no fuel.
During normal operation my vehicle's check engine light came on. The acceleration became sluggish. After stopping the vehicle "putted" and then stalled. After putting the car in park it restarted fine, however this has happened 3 times in the last month. The vehicle is currently out of warrant due to mileage so I have not yet taken it to the dealership but will if it happens again.
As I am going down the road the tachometer starts to jump around and then I lose the directionals and my lights. If I turn off the ignition it will not start again. This has happened four times in the past year. The dealership tells me that fuse #22 is blowing. As of today, my truck is still at the dealership and they do not know what is causing it. They have replaced the fuse each time. They also replaced the instument cluster and the ignition lock. I am seeking legal advise.
Since January of 2005 my 2003 trail blazer has been blowing the ignition fuse every time I start my truck. It will try until I turn it off and than no power. When this happens my turn signals go out, and my gauge goes hay wire. I thought it had to do with my remote start, and I had that completely removed. Now it does it more often. I took it to the dealership, and they charged me $20 to put a fuse back in which I told the dealership that is what I have to do to get it started, but it will blow again. Before I left the dealership the fuse blow the service manager just came out and replaced the fuse again and did not care that it was going to blow again. He basically just wanted me to leave the dealership. Guess what before I even turned out the fuse was blown again. When I dropped it off they were suppose to figure out what was causing this to happen, but they said they replaced the fuse, and it was fine. If I wanted them to look into it further it would cost $300. Just to look at more. I am pretty much at a loss because my vehicle is over the miles, but is only a 1 and a half years old. I don't know what to do. I think it was really bad that before I left the dealership I had the same problem , and they were fine with letting me leave.
Vehicle shut down while driving on the freeway, ignition locked. Consumer shook the steering column and it started. There was a multiple vehicle collision since the vehicle shut down at 65 mph.
The consumer stated the vehicle intermittently did not start. The dealer replaced the ignition twice.
Consumer was trying to accelerate but vehicle would not move, and then stalled. Consumer was able to restart the vehicle, and drove it to the dealer for analysis. However, the mechanic was not able to resolve the problem.
