While driving my vehicle on a city street at approximately 45 miles per hour, I set the cruise control to maintain the 45 mile per hour speed. After less than 60 seconds, the cruise control cause the vehicle to accelerate rapidly to 85 miles per hour. Stepping on the brake at first did not cancel the cruise control. When it did finally cancel, I continue to drive manually. The cruise control then took over again and cause the vehicle to accelerate rapidly, exceeding the speed limit. Once again, the brakes were applied and the cruise control cancelled. The cruise control was turned off at the main switch on the turn signal stem. Later on, the cruise control was turned back on and tested again with the same results. After the third attempt to set the cruise control at 45 mph, the cruise would not set at all. The vehicle was taken to an independent repair shop. They were not able to find any specific electrical problems. But they did indicate that the cruise control module itself would probably be at fault. If the cruise control switch is left in the on position, but the cruise is not set, it may randomly take over the throttle and accelerate or sometimes hold its own speed for several minutes at different rates of speed. This creates a hazardous situation for all occupants of the vehicle along with others that may be in the path of the truck when it randomly accelerates. As of the time of this writing, a solution has not been found to correct this situation.

I purchased my 2005 Chevrolet 2500hd duramax in may of 2015. A week later I was pulled over for speeding 10 over. My truck showed I was driving 55 mph. I now have a speeding ticket $114. I contacted GM about the issue and they said my VIN# was not qualified for the recall and I would be paying out of pocket ($535 including labor). The part alone is $350. Now at the end of the day I will owe $649 because of GM's mistake. I love GM's products, however they do not stand up to there mistakes which will make me think again before buying one.

2005 Chevy Silverado 2500 hd duramax, speedometer stuck on 23 mph. Known issue with faulty part, the instrument cluster stepper motor. GM will not cover replacement. Faulty parts used from 2003-2007. Class action suit only covered certain VIN numbers and no recall was done. Safety issue/concern. Was informed by dealership that if we had brought it in 8 months earlier it would have been repaired at no cost. Never received notification of potential for this to happen. There should have been a recall...

I purchased a 2005 Chevy Silverado in late 2010 from a Chevy dealer (tom clark Chevrolet in mckeesport, pa). Approximately June 7, 2013, my speedometer went crazy sticking on 0, 100, or 120... regardless of my speed. I contacted the dealer Monday June 10, 2013 and was told to bring it in for them to look at it. I took my vehicle in to tom clark at 7:55 a.M. on Tuesday June 11, 2013 and received a phone call from them at approximately 8:45 a. telling me that the issue is the cluster and he agreed that this issue is the exact issue that was raised in the GM lawsuit but still told me that they would not fix the problem. (I only became aware of the GM lawsuit over the weekend of June 7, 2013, while searching the internet to try and find out what could be wrong with my vehicle). He then informed me that they wouldn't fix it because the warranty/recall expired last year (2012), so he does acknowledge that a problem exists and has existed. I purchased this vehicle after all the issues with them surfaced and a lawsuit had actually taken place and they sold me this truck, knowing there was a problem and didn't inform me of the problem. Now they are telling me that it will cost $550 to fix it. My vehicle has 49,809 miles on it, it's a third vehicle that's hardly ever used and there is no excuse for the dishonest practices of tom clark where this matter is concerned. They sold me a vehicle with a defective part, while a lawsuit was either pending or had been resolved, and still failed to inform me of the problem. Now they want me to pay $550 to fix what they already knew was wrong.

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.

: the contact stated that on several occasions while driving 60 mph on dry roads, the vehicle engine light illuminated. The contact depressed the accelerator pedal, however the vehicle would not accelerate. The vehicle was pulled over to the side of the road and shut off. After two minutes, the vehicle was restarted, and resumed functioning properly. The vehicle was taken to a service dealer, where the dealer was unable to determine the problem.
