Driving 60 mph on a 20 mile bridge, the engine failed (engine light and traction control light were on. No power steering or power brakes. Nothing appeared to be overheated. 2 hrs later it started, 5 minutes later it killed again. Towed to nearest dealership. They road tested it and car failed again. Found 1 broken wire inside wire insulation. Repaired. Picked up car and it failed 1 mile later, took it back to dealership on "reduced engine power". They found 2 more broken wires. Replaced harness. One week later it happened again. After brief wait it started and ran for another day until I could get it to the dealership purchased from. They could not find anything wrong. Two weeks later it failed again. Tow truck took it to another dearlership. They changed another part relative to the fuel system and said it "may" be fixed. I refuse to pick it up or drive it again; it's dangerous and undependable. Have asked gm for another car and I am waiting for their response.
