| Assist problems |
While actively driving at speed this loaner vehicle, the vehicle's driving assistance professional package (dapp) completely deactivated without warning. This caused an immediate, unexpected loss of both adaptive cruise control and active lane-keeping steering assistance, requiring sudden manual emergency intervention to maintain control of the vehicle and avoid a collision. This is a severe safety defect. The vehicle has been presented to an authorized BMW dealership twice for this exact failure. It is currently on its second repair attempt and has been out of service for over 20 consecutive days. The dealership and manufacturer have been unable to permanently resolve my personal vehicle this electronic/steering system malfunction.
