Update by user Jun 24, 2021 Over 80 days in the shop! GM customer service does limited contact with me. Offered an extended maintenance warranty for my inconvenience. I have driven over 850 miles back and forth to the dealership at countless hours. GM finally sent a new top and motors today. They also sent an engineer to help install it. Headliner is damaged from all the removal and the dealer ordered a new one. We will see if it finally fixes the problem after 6 months! Original review posted by user May 25, 2021 I have posted my issue before and it is ongoing! I have ask GM customer service to replace my car with a new one! My 2021 Corvette HTC is in the shop for the fourth time because the top will not open and close. It may work 5-10 times and then crash when it closes. In the shop 22 days the first time 3 days 2nd time 32 days the 3rd time and I just took it back again. I have pages of service work and parts they have replaced and I have no idea if it is going to close. Mechanic has 40 years experience and has no idea what to do. User's recommendation: Beware corvette HTC.
