NHTSA Complaint #11444620 — 2015 BMW X5

Engine stalled at low speed. Was able to restart engine. Check engine light was on so was able to drive it to dealer. Dealer determined it was hpfp failure, with metal shards in fuel line, so entire fuel system replaced (injectors, lines, hpfp, etc). Hpfp was replaced with the same model that failed, just a new one. A while later, engine stalled again at low speed. No check engine light but was able to restart engine. Dealer notified of stall post-fix of entire fuel system. A while later engine stalled a 3rd time while driving around 40 mph. No check engine light Was advised that there was a recall for a newly designed hpfp but not in stock at dealer yet. Eventually had the newly redesigned hpfp installed under recall. A few weeks later, experienced another stall while idling at a red light. Amazingly was able to get a real-time video of the engine stalling and shutting off. No check engine light. Was unable to restart engine after multiple tries but engine finally fired up on the 5th or 6th or 7th attempt at restarting. Was able to pull over to the side of the road and notified dealer that I experienced another engine stall after installation of the newly designed recalled hp fuel pump.. Took the car into the dealer and showed them the real Time video of my engine stalling and dealer sent diagnostics to BMW North America but Was advised that BMW engineers were unable to replicate or to find the problem that caused the engine stall. Full credit to local BMW dealer that has always tried their best to help me find and fix the problem but the engine stalling randomly is a life or death kind of malfunction. After 4 engine stalls including after a replacement of a recalled brand new design part, I'm hoping BMW North America can work with me towards a solution and not have to wait till a catastrophic accident before a remedy is offered.
