Warnings
2013 corvette grand sport. Service traction control and service active handling system warning came on after starting my car. Also engine warning light too. One minute car running great. Shut down for five minutes now running like crap. What's wrong?

This actually comes up a lot. First thing to do is check your spark plug wires. You have to remove the plastic covers on each side of your motor and check both ends on the spark plug wires. One of them may have come loose causing all your issues. If so, it's a real simple fix. Just reattach and make sure it's secure.

I know it appears counter-intuitive that a spark plug wire issue could trigger an AH/TC DIC warning and CEL, but it's surprisingly very common.
If the spark plug wires are all intact, the next items to check are the large blue connectors near the fuse panel in the passenger's foot-well.
And/or have your codes read. Many auto parts stores will do this for free.
