Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Silverado 1500 Hybrid 8-cyl

  • 71,380 miles


Driving about 60 mph about 10 miles into the trip when the truck lost speed, the ABS brakes did a slight on and off pulsating every couple of seconds, the engine was running rough and giving it gas the engine revved up but wouldn't go anywhere. Speed dropped down to 35 or 40 mph and wouldn't go any faster. The dash indicator showed messages stating stabilitrak traction control turned off and check engine light is on. It jolted real hard when it shifts gears. When I mashed the brake it didn't want to come to a complete stop without pressing the brakes to hold the truck there. I pulled into a store popped the hood and finding nothing I turned the truck off for a few seconds and restarted it but nothing changed and the error messages were still being displayed. The trucks engine was running rough. I headed home and it didn't have any power and jolted hard as it shifted gears. I coudln't go but 35 or 40 mph on the level ground. If I went up a slight hill the truck slowed down more until I got past the hill. I gave it gas and the engine would rev up but had no power and wouldn't go 35 or 40 mph. I parked the truck in the garage and in 10 minutes I went to start it to get the error messages and it started up fine and the engine wasn't running rough. I drove it 1/2 mile down the road and back and it ran perfect. I googled the error messages and found alot of complaints and comments about this issue on the Chevrolet forum website. No recall information just alot of people experiencing the same issue and alot worse cases that almost caused accidents. Is there a recall on this issue? I read that I will probably have the issue again because after it sits for 10 min it probably won't have a problem until a few minutes or days later. I can only hope doesn't cause me to have a wreck and kill myself or someone else. This is a major issue and should be recalled to fix the problem.

Speed control (cruise) does not hold. While going down an incline from the mountains, cruise control was set for 65 mph, and the vehicle increased speed to 85+ mpg before applying brake to slow down. Called dealership and took vehicle to be checked in regards to this incident, and they stated that due to the department of transportation, new emission standards that transmission was made not to hold so as not to increase carbon footprint. This causes a very unsafe condition when driving when the cruise control is engaged.

This is a dealer demo vehicle, first 2235 miles were demo. During my first morning (12hours after picking up at dealer) of ownership I was descending down a hill with the cruise on, and the vehicle proceeded to over speed approximately 5-7mph. I travel this hill both ways to/from work daily and this happens everytime. I though this might be an abnormal adjustment within the computer/etc so while taking in to the dealer for a TPMS (tire pressure monitor system) issue I mentioned the overspeed issue to the service write up and they said that it was normal. I don't agree, but maybe it is. It does adjust back to normal cruise set speed but is unique. I had a 2002 Dodge Ram 1500 previously and it did not do this, and I have drove otr (over the road) semi-trucks and know the difference with overspeed being normal and abnormal. I would like this to be looked into, as it could be a hazard that could lead to unsafe situation.

#1. vehicle accelerates when letting off gas, even while going uphill the vehicle will accelerate. You can go up a steep hill without touching the gas. Brought the vehicle to the dealership they replaced, the throttle body, gas pedal assembly. They reinstalled the original parts and told us that this was normal. We drove other 2011 Chevy Silverado's which did not do the same thing. The dealership told us that all the 2011 Chevy Silverado's accelerate on their own. #2. there is a clunking noise from the rear when driving over bumps. The dealership said this is normal backlash, and did not do anything.

My 2011 Chevrolet Silverado 1500 has unwanted acceleration. Its been happening for apprx a month, on and off. On Tuesday 10/4/2011 I was leaving my parking space at work, I had my foot on the brake as I was turning out of the space, the vehicle just took off - accelerating without touching the gas. I then hit the brake which stopped the vehicle. I then got on the highway - (I-94) to head home, while driving on I-94 my vehicle lunged forward nearly striking the vehicle in front of me. I then backed off and kept a safe distance in the event that it happened again, sure enough - my vehicle started accelerating on its own. I realized it was doing it and had enough distance between me and the other vehicles ahead, so I allowed the vehicle to take off. My Silverado got up to about 1500 rpms at 60mph, I clearly had my foot off the brake and the gas, feet flat on the floor. I allowed it to accelerate on its own for apprx 1 minute but then had to stop. It is clearly driving itself. I drove the truck straight to the dealership and left it for the shop to look at the next day. The service dept could not re-create the problem, go figure. In the past month I've nearly hit several parked cars when pulling into parking spaces as the vehicle takes off accelerating, in these events I was also able to stop the vehicle w the brake.
