Check engine warning light came on then immediately lost all engine power completely stalled), electrical (except headlights), power steering, power brakes. Engine would not restart after vehicle stopped (went into walk home mode), not even the horn would work! after about 20 minutes, the engine would restart and I could drive home, but with the check engine light on. I took the truck to the dealership the next day. The reprogrammed the main computer. After a few days, it happened again! took the truck back to the dealer. They said they would need to order a new computer, they reprogrammed the defective computer again and said they would call when the new one was in. The same condition repeated itself a few more times before the new computer came in and they replaced it. No problems since. I consider loosing all power in a turn onto an interstate rather dangerous! the dealership confided my experience was not at all unusual with these vehicles.

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.

Engine and electrical system shuts itself off, this has happened more than twenty times since we have owned this vehicle and GM just ignores it.

I have a 2010 Chevy 2500 hd when I put the car I park it sounds like the doors unlock but they don't it started on my drivers door now its happening on passenger door. I've tried to unlock manually it wont work I've unlocking from the remote and the door lock switches on both doors it takes multiple times with both and then able to get out. This is a major safety issue !!!!. I only have 27000 miles on it now and its out of warranty I tried to get into my truck with remote and key it took multiple times to get into also... I have a friend with a 2010 denali he's having the same problems I could see if the truck was over tens years old and over 150000 miles having problems but this isn't right... I take my grand kids all the time I'm scared to take them in case I have to get them out in an emergency and needed to get out fast that I wouldn't be able too or for that matter just myself driving alone!!!

Right after I bought the truck in 2010 I notice right off my brakes weren't working right.so I got in touch with the dealership and they told me to bring it in I took the truck in and they had one of their employee to take it for a drive around town he came back and said nothing was wrong but I still had the problem so icalled them back again and then they told me to get in touch with General Motors so icalled them and talk to 2 different people there and then General Motors called ramey Chevrolet in richland va and they told general motor that where welive in the mountains that it would cause the brakes to do that but the only mountain I have to cross is the one going to the dealership but it not a high elevation to climb to where I would have to use my brakes alot and this is not the only problem I have had out of my truck they had to put some sensors on the motor because the truck just up and quit on me coming home one evening and I have had to have some new rubber seals put around the doors due to water coming in and causing my floor board to rust out and I have all my paper work on the work I have done on it my truck is suppose to be still under warranty and this has all happen in the first year I own the truck sincerely.

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.
