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.

2003 chevy trailblazer with 34100 miles service engines light comes on, I take it to the dealer who fixes it and recommend I have the transmission and another regular maintenance completed that cost me over 400.00 dollars. Two weeks later I have to take it back becasue the speedometer went past 115 miles while sitting still, a week later the transmission starts stalling while going forward and the engine fan is running constantly even on start up. Checked the fluid I had none in the transmission. Yet it was suppose to have been filled when maintenance was done. Took it back to the dealer it is no longer under warranty and just under a hundred miles later my 2003 chevy trailblazer which is 3 years old. There is a problem with the transmission in the chevy trailblazer and I am not the only one experiencing this. Something needs to be done. Help.

My 2003 trailblazer ls engine has stalled and completely died while I've been driving it numerous times. The first time was on 9/8/06 and I was slowing down at a stop light, about 35 miles an hour, the engine just died, and I had traffic behind me and was nearly rear ended. I finally got it restarted after turning off the AC and got it off the road, towed to dealer and they could not find anything wrong after 2 days. I got it back from the dealer and it proceeded to die on me on 4 separate days, each time when slowing down and with the A/C on. I've so far been able to get out of the way of oncoming cars and get it restarted, but refuse to drive it on the interstate for fear of being rear ended. I took it to the dealer again on 9/18/2006 and they kept it for 3 days while I paid for a rental and could not find anything wrong with it. All they did was drive it around a few miles and tell me they couldn't get it to fail. On the way home from the dealership, it failed on me again. I've researched on the internet and this seems to be happening with a number of 2003 trailblazers, I can't believe chevy doesn't know what is wrong.

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.
