Failure Date: 05/11/2013

My son and I were out today shopping locally only about 1 mile from our home. The car was fine and everything was great until all of a sudden, the acceleration on the car started to decline even though I had my foot on the gas the car just seemed to do nothing. I was in the middle lane and traffic was vicious, I turned on my hazards and attempted to try and push on the gas. I car came to a stop but the engine was still running, it felt like I was in neutral but I was clearly in drive. I contacted onstar they called the police to make sure we did not get in an accident, as I stated earlier, we were in traffic. I received a push to a safe side of the street and tried to restart the car over and over again, the car started up fine, it just would not go anywhere, no movement. I had to get it towed to my home because it was 110 degrees and I had my youngest child with me. We waited 2 hours for the tow truck, I was dehydrated and faint by the time we made it home. My husband contacted the dealership as we just purchased the car in February of 2013 from ezcarsandcredit in riverside CA, they said don't worry about it, they will have the manager call us back to take care of the problem, that was 4 hours ago and still no call.

When it is cold outside and the engine is started it knocks and ticks until warmed up. Gm customer service will offer additional miles on the warranty but no additional time. The dealers will not fix the problem. Gm says it is a piston problem. This problem happens every day below 50 degrees. That is 8 months of the year in michigan. The truck is embarrassingly loud. Sounds like it is 20 years old. It is only 5 months old.

Failure Date: 11/28/2002

I own a 2002 Chevrolet Trailblazer LS with approximately 11,000 miles which had an engine failure on thanksgiving 2002. Entering and accelerating to approximately 60 mph on highway in about 25 degree temperature and engine service light appeared followed by reduced engine power light and then engine stopped running and could not be restarted. Dealer advised me that number 4 cyclinder cracked. They further advised me that gm is aware of a manufacturing defect in some Trailblazer engines that was caused by a miscalibration of the machine used to manufacture the engine. Gm replaced my engine at no cost to me under original warranty. This sudden engine failure could have resulted in an accident and possible personal injury if I had not been able to roll the vehicle to the breakdown lane safely. From NHTSA web site.
