GM’s recall says that the problem affects 674 of the 2020 Corvettes. As for the rest of the vehicles, the quantity remains undisclosed. The recall and stop-sale covers vehicles on dealer lots, in transit, and already in customers’ driveways.The brake-by-wire system works by applying an amount of pressure to the brakes based on information coming in from electronic sensors, rather than relying on a physical, mechanical link between the driver’s foot stomping on the pedal and the brakes. When promoting the C8 Corvette, GM said its new eBoost brakes “are more precise and tunable.”
