year Cadillac CT6, 2020 2021 model year Cadillac CT4 and CT5, and 2020 2022 model year Chevrolet Camaro vehicles equipped with a 10-speed transmission. A transmission control valve in some of these vehicles may be susceptible to excess wear over time, resulting in a gradual loss of pressure within the valve that can cause harsh shifting. In rare cases, the wheels may experience a momentary lock up. If the wheels lock-up momentarily while driving, there is increased risk of a crash. Dealers will install new transmission control module software that will monitor valve performance and detect excess wear approximately 10,000 miles (16,000 km) before a wheel lock up condition could occur. Once detected, the transmission will be limited to fifth gear, preventing the possibility of a wheel lock up condition, which occurs in a downshift from eighth gear. A service engine light and reduced propulsion message will also display in the instrument panel.

driver?s seat when entering the vehicle, it may cause the seat belt pretensioner to bend sharply over the seat side shield. If this continues to occur over an extended period of time, which is very rare, the seat belt pretensioner cable may fatigue and eventually separate, which could reduce the effectiveness of the driver?s seat belts. Before any damage occurs to the pretensioner cable itself, signs of wear will be visible on the pretensioner cable cover where it has been repeatedly bent over the seat side shield. Dealers are to inspect the driver seat belt lap anchor pretensioner and replace if necessary. The repairs will be made at no charge to the customer.
