Power train, Fuel/propulsion system, Jun 29, 2025
Car just shut off when driving at 65mph and never started back up, took it in and repair was a bad fuel pump and fuel rail line causing metal shards to go through fuel tank and injectors.

My 2018 bmw 320 stalls and cuts off when I come to a stop. Very dangerous. It has cut off in the middle of the road. I have checked online to see if this is a common issue. Other bmw owners have reported this same issue. There has been a recall on other bmw models with this same issue from 2014-2018 for fuel system and fuel pump that may cause this issue. Letters were sent out I. January of 2022. My 2018 bmw 320si has not been included in this recall for some odd reason. When car shuts off a warning message appears on screen. One message states “transmission not in park.” Or “drivetrain malfunction”. This began to happen on November 2022. I have taken my vehicle to two dealers. One was an independent repair shop and the other was a bmw service center. Both reported issues with fuel pump that would cause this problem.

Multiple codes came on right after I had gotten my thermostat and my water pump fixed. However it ended up being that there was more leaks throughout the rest of the car. The car has currently cost me $3400 to fix and it’s still not fixed because nobody can figure out where the actual leak is coming from. The coolant is leaking and nobody can figure out where, it’s been having jerking issues since it started leaking and I read on other Bmw’s that the coolant leaks into the head gasket, causing the engine to blow
