GM tells the National Highway Traffic Safety Administration (NHTSA) that “A transmission control valve in some vehicles may be susceptible to excessive wear over time, resulting in a gradual loss of pressure within the valve.”
That can cause harsh shifting and, eventually, trigger the rear wheels to lock up.
Drivers might notice the transmission downshifting at unexpected times, a check engine light, or a “reduced propulsion message” as the problem develops.
Dealers plan to remedy the issue by installing new software that will “monitor valve performance and detect excessive wear approximately 10,000 miles before the wheel lock up condition could occur.”
GM is not aware of any warranty claims, accidents, or injuries related to this recall.
GM notes that some vehicles previously recalled may have had the wrong software version installed. These vehicles will be included in this recall and, if necessary, the correct software will be downloaded to resolve the issue.
This service is free of charge, as recall repairs always are.
