Two problems related to car stall have been reported for the 2013 BMW 650. The most recently reported issues are listed below.
Prior to 4/3/2018 on approximately 4 different occasions, the vehicle started and idled rough. Engine was turned off and re-started and ran smooth. On 4/3/2018 the vehicle stalled while driving and in traffic and would not restart. All engine power was lost (no power steering, no forward motion) but all electrical functions were ok. Towed car to BMW dealer where they found (2) high pressure and (1) low pressure fuel pump failures which were replaced under extended warranty. No other issues were discovered through the inspection and repairs. On 5/22/2018 (pm) upon starting the vehicle it ran rough. We tried to stop and restart but it did not correct the problem. On 5/23/18 (am) the vehicle started properly and was taken into to the dealer to diagnose the problem. On each occasion noted above the display screen prompts with the drivetrain malfunction message, but checking the on-board vehicle status all systems are "ok". Reduced power and/or complete loss of power in a critical situation could prove to be disastrous. Considering the number of complaints and potential risk the factory should elevate this complaint to a recall status before someone is seriously hurt (if that hasn't already happened).
