Bought a new ZR2 in July, have 4K miles on it, and getting these error messages. At startup, the dash also says “Reduced acceleration, drive with care”. Did anyone else get these before and if so what did you do?
In Colorado on a trip with the family and don’t have a Chevy dealership for 4 hours…
Looks like a dealership visit is in your future. But until then, try restarting the truck a few times. Sometimes that helps to clear out error messages. Also, if there’s an auto parts store nearby, they might be able to clear those codes for you before heading to the dealership. By the way, awesome truck!
