“I was driving down the highway when the check engine and low power lights came on. I lost all acceleration and my RPM's dropped to nothing. Codes that came up were for the throttle body. I read a complaint that states GM knows about this issue. Why haven't they done anything about this?”
NHTSA complaint #10592172, filed 2014-05, 72,000 miles“I recently purchased this vehicle 3 weeks ago from a dealer in st augustine, florida. The engine will just shut off when I am driving, I have two young children and am concerned that this could cause an accident when driving. I have not been able to get any help from the dealer where I purchased the vehicle even to do a diagnostic on the vehicle. Has there been any problems/ recalls with the ignition switch on this make and model, even when at idle it will shut off, without touching anything.”
NHTSA complaint #10705183, filed 2015-04, 121,146 miles“This is the second time this has happened - what happens is I will be driving ( speed once at 35 once at 60 ) and my Trailblazer just shuts down. Instantly. You have no power to get over to the side of the road. P0601 code - this is what shows on my mechanics system. However, when you research that code online. Some folks have spent thousands trying to stop this issue and no resolve. This is highly dangerous - you go from 60 to nothing. My tb has less than 50k on it.”
NHTSA complaint #10535149, filed 2013-08, 47,000 miles“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. …”
NHTSA complaint #10511527, filed 2013-05, 121,000 miles“Vehicle was serviced for a faulty fuel level float sensor, which was registering that there was no fuel in the gas tank when the tank was full. 7 days later, while driving on a busy freeway, all of the gauges on the gauge cluster started spinning out of control and the vehicle lost complete power while driving 65 MPH. I had to merege across 4 lanes on the freeway in heavy traffic and nearly got run over. No power to the engine at all - it just died while I was driving. Of course, onstar and the Chevrolet dealer that performed all of the service on the vehicle were no help. …”
