Official summary
Region Letter: August 28,2018 The instructions for Option #1 have been corrected. An Electronic Control Unit (ECU) in the subject vehicles has improper programming that could lead a component in the Continuously Variable Transmission (CVT) to unnecessarily cycle and experience abnormal wear. If this component becomes damaged, the Malfunction Indicator Lamp (MIL) may illuminate in the instrument cluster and the vehicle could experience a reduction of speed. After reaching a pre-determined gear ratio, the vehicle can be operated up to approximately 37 mph.
