Dash readout: Engine power reduced, vehicle went dead. This has happened at least 15 times in the last 30 days. Usually while driving down the road but will also do this parked and idle. Vehicle loses steering capabilities and comes to a stop. This has occured in several different scenarios, including heavy high speed traffic, pulling a loaded trailer, making it very dangerous because of losing stopping capabilities.

While driving to work in heavy traffic, my 2010 Chevrolet Silverado with 27,000 mile suddenly lost power and slowed from 50mph to 25mph in a matter of seconds. Due to the extreme reduction in speed with out my brake lights being engaged, a vehicle following me had to make an emergency maneuver, turn in the right lane, and almost struck a third vehicle. Three warning messages were given that included, engine power reduced, traction control off and service stabilitrack. The vehicle started to run extremely rough and I pulled into a parking lot. While in the parking, lot I researched the above listed messages and found that several other owners have experienced the same problem that has been linked to the throttle body system and the intake. I then researched if any recalls have been issued for this vehicle. I found that a service bulletin was issued but not a recall. I was also surprised that this issue appears to have nothing to due with stabilitrack. I then limped the vehicle home at 20 mph. When the vehicle would shift from first to second gear it would lung forward violently. I later called the pitre GMC, in albuquerque nm, and spoke with a service representative. I asked him if a recalled had been issued for these vehicles in reference to this type of incident. He stated that he did not know of a recall but I could drive it down to their service department and they could check the codes on it. I was surprised by his response instructing me to drive an unsafe vehicle. I believe this issue needs to be addressed due to the likelihood of a motor vehicle crash that could result in sever injury or death. Hopefully GM and NHTSA will not wait until there are numerous deaths to address this problem. This is potentially as dangerous as the ignition switch issue that killed several people. I am a generational Chevrolet consumer, but that will probably change.

Truck wouldn't restart when backing out of a driveway on the highway and shifting into drive. Also there is a vibration heard when driving about 30 or 40 miles per hour. Took it to the Chevy dealer where it was bought and they said nothing was wrong with it and that they tested it out.

Engine, powertrain and electrical shut down, fuel shows empty when full, has happened nine times while at speed. Have to coast to stop where ever room can be found, turn key to off and wait then restart.
