I have a 2011 silverado. My "ENGINE POWER REDUCED, SERVICE TRACTION CONTROL, and engine light came on. I almost got rear-ended because the truck lost power. I took it to the deal today and they said that the Throttle position sensor needed replaced. They also told me that GM is aware of this and have a special coverage #11273 extended the warranty. They replace it for free. I then got a number to call GM and complain. Hear it is 1-800-222-1020 Everyone need to call and complain about this so we can get them to more about it. I asked what happens when the extension runs out and this happens again, am I gonna have to pay for a problem that GM knows about? They did not have a answer for me. All she could say is , the dealer fixed it right. I said yes but what happens when this happens again and I do get rear-ended, is GM gonna pay to fix my truck or give me a new one because they can't fix this issue?
