NHTSA Complaint #11485449 — 2022 CHEVROLET CORVETTE

I have not experienced a safety incident, but have been warned not to drive the vehicle. The vehicle has 1850 miles. I recently got a message on the Driver Information Display “Rear Axel System Off”. I also receiver an email from OnStar “Engine/ Transmission fault, Seek Service Immediately”. After analysis at the Dealer, they concluded with GM that the transmission needed to be REPLACED. They indicated that it is NOT safe to drive and I should leave it at the Dealer. No other comment as to why. I found that GM reported (September, ‘21) that their transmission supplier had left out two of six bearings in several transmission units…and that they believed that only 19 vehicles were affected. Also commenting that this defect could cause a sudden loss of power resulting in loss of control…however no serious incidents have been reported. My vehicle was assembled in December ‘21… 3 months after GM’s discovery of the issue. I believe that the defective transmission issue is more extensive that GM is acknowledging. A replacement transmission was ordered for mine, but none is currently available (back-ordered). Local Dealers are backlogged with transmission work. My Service Rep (reluctantly) admitted that this is the second C8 Corvette transmission they had to replace. This is a high-profit & high-profile vehicle for both GM and it’s Dealers. I feel GM should disclose how many defective C8 Corvette transmissions they have replaced and more accurately assess the production-dates for affected vehicles.
