general problems of the 2012 BMW 550

I was driving when the vehicle engine randomly shut down with out warning I was on the freeway at the time and could have been hit by a car. I took thr car to an auto repair shop, had the problem inspected snddiagnosed and was told the engine was faulty. I had the engine replaced and the same issue occurred. There were no warning lamps, messages, or alerts prior to the problem occurring. The drivetrain malfunction light came on as soon as the engine cut off.

2012 f10 had issues while running as car installed and stopped completely multiple times in traffic. Fuel supply sign came on. Diagnosed as low pressure fuel pump degraded and need replacement. Same recall took place for 2007-2011 5 series model as well via recall campaign no. 16v-746: in-tank fuel pump. 2012 have same issue and very dangerous to drive on road when vehicle stalls and stops while driving in traffic.

When you first turn the car on it sounds very loud for about 5 minutes (louder than normal). When driving down the road the car will start shaking and the car computer pops up saying drivetrain malfunction and you have to pull over to restart. Hesitate beofre taking off at a red light or when turning in an intersection. Computer error massage comes and goes.

When driving down the road the car will start shaking and the car computer pops up saying drivetrain malfunction and you have to pull over to restart the car. But it does it again 5-10 minutes later.

When I press on the gas to accelerate the "drivetrain malfunction" error comes on. My car only have 51,000 miles. I have to turn the car off and wait a minute to resume driving.

Car will stall jerk and stall losses power while accelerating.

"takata recall" our car started flashing "increased battery discharge" and "all electrical devices will shut off" we took it to the BMW house. They diagnosed it, as needing a new battery. We replaced the battery and 1 week later the same message came on again "increased battery discharge' "all electrical devices will shut off" . We had to take it back to the BMW house and they diagnosed it this time as needing the external door handle replaced, they said the door handle had gone out and that some part in that handle puts the car to sleep but it was not allowing the car to go to sleep and this pulled the battery down. We replaced that. That lasted 2 weeks and again this same message came "increased battery discharge" "electrical devices are shutting down. I was on the way to the BMW house once again it started to smell like wires burning and under the console where the gear is started to smoke bad!! to the point that I parked the car then I called the fire department. Our car had to be hauled to the BMW house. It is unknown why all this happened.

The car threw a drive train malfunction code which happens weekly on these engines and the car jumped a lane as it misfired and went into limp driving mode. If there was cars next to me there would have been a crash. Since then BMW has issued a customer campaign on the n63 engine effecting thoughts of cars. They are changing tons of parts from injectors to fuel rails. It should be a full blown recall and the NHTSA should get involved on this. My car has been in the shop since 12/23 and still has not been repaired correctly. I have a feeling you are going to be getting thousands of these complaints against BMW. They need to be held accountable for these failures.
