This truck has on three separate occasions shut down while driving and would not start back up. The truck had to be towed to a dealership and the ignition switch was replaced all three times. The last time it was driven off of the lot and made it 4 blocks before it stopped running again. It was towed back to the repair shop and is still not running.

1st incident (July 2004): While driving about 20 mph, vehicle stalled in the middle of the road. Could not get it to start and key locked in ignition while truck was still in gear. Other times previous, vehicle took a few times to start. Ignition switch was intermittent. While in for repair first time, found that when vehicle stalled, it lost ignition input. Codes that came up with scan check were U1000, U1016, U1152, B1372 and U1088. Ignition switch was replaced with new, fp#12450251-switch 2.188 R. all other fuses and wiring to ignition were found to be "ok". 2nd-current incident (October 2006): Vehicle took several times to start (same as original problem). Vehicle would turnover but would not start engine. Tried several times before battery died. Current evaluation from service tech is that the ignition switch is bad. Key is locking in ignition and can't move gears. Tow driver had to "jump" battery to get vehicle in and out of neutral for tow and to remove key from ignition. Still waiting on extended warranty provider to approve this replacement (although the original warranty provider is now bankrupt). We may have to pay for this repair out of pocket if warranty issue is not resolved.

I realized the problems when pulling out of a parking lot into the street, the truck came to a sudden stop and I couldn't get the engine to turn. At the same time I noticed all gauges on the dashboard started blinking and going back and forth. Luckily I was not around a lot of cars and I was able to get the car started after 10 minutes. However, what if I was driving in a heavily traveled highway" would I still be alive to make this complaint" a very much concerned Chevrolet owner.

My 11-month old 2003 Chevrolet Trailblazer has had multiple quality problems, twice affecting my safety. Most of the problems have been electrical in nature. The 4WD has become inoperable numerous times, once while driving in snow. In another incident during a severe thunderstorm at night the air conditioner (A/C) failed and I was unable to defrost my windshield in order to see. After one dealer failed to diagnose the 4WD problem, another dealer replaced my ignition switch because the technician said I had no power at all going to the "rear grid." I continue to have intermittent electrical problems, including near stalling at a traffic light, and ongoing 4WD failures. The car also has very jerky motion when in 4WD reverse, of course, when the 4WD is working at all. The dealer told me that was normal and now I see there is a service bulletin on the problem.
