Drive Train
If the transmission turbine shaft fracture occurs during vehicle operation in first or second gear, the vehicle will not upshift to the third through sixth gears, limiting the vehicle's speed. If the fracture occurs during operation in third through sixth gear, the vehicle will coast until it slows enough to downshift to first or second gear, increasing the risk of a crash.
The turbine shaft inside the transmission may fracture, which would result in internal transmission failure, lack of shifting and loss of vehicle speed. Dealers will replace the transmission turbine shaft free of charge to resolve the concern.
General Motors notified owners of affected vehicles starting in August 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The General Motors recall number is 14234.
