What is wrong
Issue:
On certain vehicles, the recall repairs completed by a General Motors dealer during recall N242454440 (Transport Canada recall no. 2024-637) may not have been done correctly. As a result, a second repair is required.
Over time, the transmission control valve could wear and lose pressure. If this happens, the transmission could shift harshly and could cause the rear wheels to lock up.
Note: This recall only affects vehicles equipped with a diesel engine.
Safety Risk:
Rear wheels that lock suddenly could cause a loss of control and increase the risk of a crash.
Corrective Actions:
General Motors will notify owners by mail and advise you to take your vehicle to a dealership to update the transmission control module software to detect excess wear in advance of a wheel lock up. If detected, a service engine light would turn on, a message would display in the instrument panel and the vehicle would be limited to fifth gear.
