Noticed that cruise control did not work while driving. Took vehicle to auto shop to have problem fixed, was told brake lights remained on even when brakes were not being applied (did not remain on when ignition was off), had the brake light switch replaced and problem was fixed. A few months later, a fellow drive told me that my brake lights were staying on while driving and then I noticed that the cruise control was not working again. Took back to auto shop, was told that the brake light switch was ok. Took vehicle to gm dealership and was told that the body control module needs to be replaced. I did some research and noticed that gm had a recall in may 2014 for passenger cars with similar problems.

My truck at speeds around 35mph while letting off the accelerator it would jump out of gear. So then, in 2012, I had the transfer case actuator motor replaced and it fixed the problem. Then just yesterday (oct. 31, 2014) I had cruise control set at 70mph and when it would coast or try to slow itself down to maintain its speed, I would here a clunking noise and it would jerk. When I let off the cruise control and would let it roll to a stop it would pop out of gear! I made it back to town and even at slower speeds it would jump out of gear to the point where I had to put it in 4wd high to be able to move. I spoke with a mechanic at the local dealership and he said they have a lot of problems with them like mine which is why I think there needs to be some attention brought to them.

We were driving our 2010 chevy silverado (with 11,951 miles on it) on the freeway in the hov lane at approximately 70 MPH. The cruise control was on. Without warning, the truck jumped 3 times and then apparently the engine just shut off. There was no acceleration, no power steering or power brakes. Once the truck came to a stop, we tried to start it again. The starter turned but the truck would not start. After approximately 10 minutes, we were able to get the truck started and moved to a safe location. Then we called and had it towed to a local chevy dealer. The report we got back is as follows: " perform system checks, scan check shows no codes stored in any modules. Road test multiple times without failure, let run in stall for 3 hours. No stall ever occurred. No repair required at this time." I questioned the mechanic about checking fuel system and he said since it was working there was nothing to check. So we have no idea what happened to the truck, but we are afraid to drive it. The incident was a major inconvenience to us, but more important, it was an extremely dangerous situation. We are fortunate that no accident occurred and that no one was injured.

Tl* the contact owns a 2013 chevrolet silverado. The contact stated that while driving at 70 MPH with the cruise control activated, the vehicle independently accelerated and the brake pedal had to be depressed firmly to stop the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 2,000.

Driving through utah at posted speed limit of 75 with cruise control on, the speedometer suddenly started to indicate a deceleration from cruises speed to 30 MPH. My vehicle did not physically slow as evidenced by my GPS which continued to show actual speed of 75 MPH. Disengaging the cruise control did slow the vehicle when the actual speeds were 50+/- MPH than indicated on speedometer. Stopping my vehicle and turning the ignition off apparently reset something? Immediately restarting my pickup seemed to remedy the problem for a short period of time. This speedometer problem has persisted for over one year requiring the continual use of GPS to confirm my actual speeds. I have a significant cause of concern when indicated speeds are significantly faster than indicated. I contacted gm dealership, only to be told they have no idea of the problem and would not confirm the continual problem. In conjunction with the speedometer problem I'm also experiencing problems with the the fuel tank levels. Gauges indicate 1/2 tank, however when fueled at that level the tank required nearly 20 gallons of fuel to full. Again the gm dealership was not concerned with the safety problem. Online searches of similar problem have indicated many chevrolet silverados are experiencing similar safety problems.

I pulled out of a parking lot on to a city street and pressed the gas pedal a little, planning to get up to about 25 MPH because there was a red light a block away. The truck responded as if I had floored the pedal. I took my foot off of the pedal and the truck kept accelerating at full throttle. I hit the brakes thinking the cruise control had gone nuts, but hitting the brakes would not turn it off. It kept accelerating with the tach over 5000. I shifted to neutral and the engine speed dropped down to idle. The light turned green and I shifted back to drive and the engine immediately started accelerating again at full throttle. I put it back in neutral, moved over to the shoulder and turned the key off. Then I started the engine again and the problem disappeared. I'm 72; if my wife had been driving by herself, she probably would have had a serious wreck. The truck is a 2014 silverado, bought 4 weeks ago, 6 cylinder work truck.

I was driving 75 MPH with my cruise control on, and the speedometer dropped to 35 MPH. Shortly after, about 10 miles, the air bag light came on. The speedometer reset after turning off the ignition switch and worked properly. This happened again two more times, and the speedometer failed completely. The air bag light remained on and is still on at 123,000 miles. Diagnostic check showed number 1 air bag sensor fault. Replaced sensor. Air bag light still on. I sent the speedometer head to a private mechanic in minnesota, and it now works fine.
