Vsa Warning Light On problems of the 2012 Chevrolet Colorado

At first, truck showed tps alarm ,then stability alarm ,next it had the headlights cut out on the highway at night @ 70 mph for 15-30 seconds. It has shown these problems separately and simultaneously at different times. Finally it manifested a new symptom I would intermittently not crank the engine over even though the battery was at full charge. After repeated trips to the dealer(they said they could not reproduce the problem) with no effect or improvement, a call to Chevrolet netted a case number #71-1257538002. As a result of this call( I feel) work was restarted on the vehicle. As of today 12/26/13 the Chevrolet dealer has now changed the ignition switch. We shall see. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The "service stability system" warning light comes on and stays on until the vehicle is shut down. It does that repeatedly. The Chevrolet dealer, jim cook Chevrolet in marion, nc, says they cannot duplicate the light or detect a code and that there is nothing wrong with the vehicle and the light is meaningless and I should disregard it. The user manual states that if this light comes on the vehicle should be immediately parked and taken to the dealer for repairs. This has happened repeatedly for the year I have had the truck. It has been in the shop numerous times. On one occasion, may of 2014, the shop tech at jim cook did see the light come on and he changed the "yaw senor". It did not fix the problem. Now the dealer service manager denies that anyone ever saw the light come on at their shop. Also, the jim cook manager says that all records they have of serving this truck were sent to gm on orders of the regional gm office and they no longer have any records of serving the truck. The light still comes on and I am afraid to drive the vehicle. Chevrolet customer service opened then closed a case on the issue and now tells me I am simply a dissatisfied owner and they will not longer service the truck or deal with me. I even asked the dealer if they would take the truck back in trade for another vehicle, as I really need a reliable truck. They told me that they would not take the truck in trade or in any other manner and I needed to take the matter up with Chevrolet.
