I had the same issues with my 2012 Cruze LT RS1. The same thing happened with the gauges going to zero and the car heating up very fast, the same gauges flashing like yours. This happened 2 different times about 3.5 years ago, both times I had to get it towed to the dealership. The techs actually never figured out why that was happening. They only said it could've been a loose electrical connection and they would recheck the connections. So after keeping the car for 3-4 days, they would return it back to me. This incidents occurred before the car reached 12k miles. Up to this date, I have not experienced it again since then. The dealership never replaced anything just "tighten the connections ".
