I have a 2005 trailblazer ext purchased new in july 05. Recently while driving, the car had reduced engine power, the check engine light then came on then my car just shut off. It started back up after pulling off the road but had to endure this the entire time while driving home. When I took it in for diagnosis I was told the accelerator pedal sensor needed to be repaired after having that repaired I drove home and the same thing happened with the check engine light and the car shutting off while driving. When I took it back again they noticed an additional problem " the fuel level sensor wiring was chaffing on fuel pump ground terminal" or in layman's term the wire was sitting in fuel so they had to remove the fuel tank and reroute the wires. This sounds very dangerous and if this is happening please report it. There are tsb reports on the issue with the accelerator pedal but gm has not issued a recall on this. The question is why not? I have also had to have the output shaft seal on the transmission replaced last year and again this year. Not very happy with this vehicle. In my opinion these are vehicle defects not problems you should be having with the normal maintenance issues. Gm needs to issue recalls to have these issues resolved. Oh in addition to the other problems I also just had to have the thermostat replaced in early june.

2005 trailblazer. Middle of high way engine stopped and instrument panel went crazy. Some time later ignition key worked again. I changed battery but it happened again and when I turned the ignition key to start the engine, sometimes is work and sometimes id doesn't. The dealer wanted me to pay for diagnosis fee my car is 46000 out of warranty and as I check internet forum some people have the same trouble and dealer covered the money how can I protect my family with the engine stopping in middle of highway!!!!!!!!
Dt*: the contact stated while driving various speeds, the engine stalled without warning. Afterward, the engine easily restarted. The vehicle was inspected by a dealer who was unable to duplicate the problem. The manufacturer was alerted. Updated 09/12/06.
