GM has issued a service update to its dealers informing them of an incorrect suspension calibration to some 2023 Corvette units, GM Authority has learned.
The service update document indicates some 2023 Chevy Corvettes left the GM Bowling Green plant in Kentucky with the wrong suspension calibration programmed into the Electronic Suspension Control Module.
GM doesn’t say whether the affected 2023 Corvette cars are 2023 Chevy Corvette Stingray units, 2023 Chevy Corvette Z06 units, or both. Dealers are instructed to correct the problem both in 2023 Corvette units still in inventory and those brought to the dealership for any reason by customers. The bulletin applies the New Vehicle Limited Warranty for each vehicle expires.
Affected 2023 Corvette units can be repaired by reprogramming the Electronic Suspension Control Module with the correct settings. No parts are needed to complete the repair. Inspection requires about 12 minutes and control module reprogramming roughly 18 minutes.
In other news, the 2023 Corvette also received a 3 out of 5 rating for reliability from Consumer Reports. However, the organization gave the Vette a strongly positive “Recommended” rating and a score of 87/100 overall, giving it a 5/5 in owner satisfaction and a 97/100 road test rating.
The upcoming 2024 Chevy Corvette is scheduled to go into production on September 5th, 2023. The rollout of the new model year will also bring the debut of the 2024 Chevy Corvette C8 E-Ray, a model featuring a hybrid powertrain, all-wheel drive and quicker acceleration times thanks to a combined output of 655 horsepower.
Looking at the greasy bits in more detail, the 2023 Corvette Stingray is equipped with the naturally aspirated 6.2L V8 LT2 gasoline engine developing 490 horsepower and 465 pound-feet of torque, or 495 horsepower and 470 pound-feet of torque when equipped with the optional dual-mode, high-performance exhaust system.
Meanwhile, the Z06 is powered by the naturally aspirated 5.5L V8 LT6 gasoline engine. This hard-charging powerplant generates 670 horsepower and 460 pound-feet of torque. Both the Stingray and Z06 are fitted with GM’s eight-speed dual-clutch automatic transmission.
The E-Ray also has the naturally aspirated 6.2L V8 LT2 engine under the hood, but pairs this with an electric motor developing 160 horsepower and 125 pound-feet. Combined output is rated at 655 horsepower.
A new variant (RPO code MLH) of the C8’s dual-clutch, eight-speed automatic transmission transmits the V8 engine’s power to the pavement via the E-Ray’s rear wheels, while the front wheels are motivated by the electric motor.
