The official notice
Defect
On certain vehicles, the input shaft snap ring in the power transfer unit (PTU) may not have been installed properly. As a result, the PTU could become damaged and fail. If this happens, there could be a loss of power to the wheels and/or the vehicle could move when it's parked and the parking brake isn't applied. Note: This recall only affects certain vehicles equipped with a two-speed PTU.
Safety Risk
A loss of power to the wheels or a parked vehicle that moves suddenly could create the risk of an injury and/or a crash.
Remedy
FCA Canada will notify owners in writing and advise you to take your vehicle to a dealership to update the drivetrain control module and install a diagnostic software that will monitor the PTU and warn you if it detects a problem. If you see this warning, you should contact a dealership to arrange for the replacement of the PTU.
