Consumer Description

Originally received notification of DTC "BMS_a035 - Vehicle may not restart." Vehicle was serviced and the rear motor drive unit was replaced. Was not given the oppertunity to inspect the serviced components upon request. Within 48 hours of service, "BMS_a027: Power limited, OK to drive," & BMS_a170 - (de)acceleration warning & top speed warning." My concern is related to a potential cascading problem, which cannot be diagnosed, and which will lead to failure of the propulsion system or an unexpected discharge issue / thermal event from an electrical issue while the vehicle is in use and/or parked.
