Issue
Issue:
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.
