The amber glow comes with a warning: “Reduced Engine Power.”
The issue is limited to some 2020 Corvettes.
The bug is apparently only software-based.
Nobody wants to see the feared and nightmare-inducing “Check Engine Light” glow in their car. This is all the more true when the car is new and especially terrible if you waited months and months to get your all-new C8 Chevrolet Corvette.
Unpleasant as this may be for anyone, C8 Corvette owners have also had to deal with a follow-up message from the car that says: “Reduced Engine Power.” As reported by Carbuzz, this was enough for one C8 owner to consider ditching the car for fear of an accident.
The good news is that GM’s been aware of the issue for a while and is actively on a fix. The bug appears to be nothing more than software-based and to address it, GM technicians will perform a number of software refreshes. The service bulletin related to the issue clearly states that “These conditions are not a performance issue with the TCM or transmission assembly” meaning that there’s physically nothing wrong with the car.
Thankfully, there have been no reports of C8 Corvettes actually suffering power losses or related incidents.
