Details

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.
