What 2012 BMW 3 Series owners say
Engine & cooling
August 6, 2016 - car stalled at about 50mph, just when about to go uphill. I wasn't able to make it to the shoulder leaving the car blocking traffic with my wife and daughter in it. Once it stops, it puts itself in park, making it impossible to push aside. We created a traffic jam and police barricaded while we were trying to move the car. Eventually, in about 30 mins, the car turns on. Happened after an hour of highway driving. Car seemed fine after that. August 17, 2016 - on another long trip, the car stalled on the highway. Would crank but not turn on. Almost exhausted the battery. Called a tow truck but by the time it got there, after about an hour, the car restarted. Had my odb-ii scanner with me and got code used my obdii reader and got code p142e - pressure too low in high-pressure system, which is consistent with not starting and the and the fuel system malfunction message. …
While in line in a drive thru the vehicle turned off suddenly losing all electrical power and power steering. Upon trying to start "charging malfunction" appeared on the information screen in with a red warning sign. Tried 2-3 times to turn over starter. When vehicle turned on it was time to move forward. When trying to exit drive thru drive way vehicle was very heavy and almost impossible to turn. Finally after several back and forth attempts vehicle was moved about 50 feet to a safe parking location.
