The National Highway Traffic Safety Administration reported that General Motors is recalling over 90,000 cars due to an issue with the transmission control valve that may lead to tire lockup.
According to the safety administration, this issue impacts automobiles equipped with a 10-speed transmission. The transmission control valve in certain vehicles may develop significant wear over time, leading to a drop in internal pressure. This condition could cause rough gear shifts as a consequence.
"The administration warned in a recall notice that there is a possibility, albeit uncommon, for the wheels to momentarily lock up," which could heighten the likelihood of an accident.
The recalled models include the 2020 through 2021 Cadillac CT4, the 2020 through 2021 Cadillac CT5, the 2019 through 2020 Cadillac CT6, as well as the 2020 through 2022 Chevrolet Camaro.
Out of the 90,081 vehicles that could be impacted, approximately 1% are believed to have the issue, according to the NHTSA.
In September, the driver of a 2021 Cadillac CT5 informed authorities that the vehicle’s front wheels seized up.
GM had previously examined this matter, they stated. Since these lock-ups typically did not exceed 150 milliseconds, the firm concluded that as no crashes or injuries were linked to them, it was insufficient duration for loss of vehicle control, leading them to close the investigation, as per the safety administration.
The investigation into the issue was resumed in November 2024, when a General Motors investigator discovered 115 cases of malfunctioning locks, including one case that resulted in an accident, according to the NHTSA.
General Motors' Safety Field Action Decision Authority later opted to initiate a safety recall on February 27, according to the safety administration.
Owners who are impacted will begin receiving notifications next month and will have access to updated transmission control software designed to identify significant safety valve wear and avoid wheel lock-ups.
