My 2004 trailblazer had been in the maroone service dept 5 times during the first 27000 due to loss of power, engine stop on traffic light, and service engine soon light on. The last time was last week and the light is on again. I almost had accident on the turnpike trying to pass a car, car is not responding as necessary. I previously owner a blazer, and a trailblazer and they were great. This truck is giving me a hard time, lost of time and confidence. *Jb
I was stuck in traffic on an interstate. Without warning my vehicle shut off. I restarted it a few moment later and continued down the road. Approx 30 min later while traveling 70 mph, it suddenly stopped again. During the next 2 hours, it quit 5 more times, usually at stop signals. I took the vehicle to the dealer who had it for two days and couldn't find anything wrong. *Ak
