“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. …”

“When vehicle is in motion, accelerating, 'drivetrain malfunction' light pops on, vehicle loses all power, runs rough, and stalls. This has happened on a highway while driving twice, and vehicle becomes instantly disabled. This has happened with several other 2012 ' 2015 Bmw 6-series coupe/convertible owners as well. Extremely dangerous malfunction, considering it happens while accelerating, or driving at highway speeds, car becomes disabled with no power to avoid potential accidents. Private garage was unable to identify and repair, and Bmw has not considered this to be a problem.”

Replaced O2 Sensor as well. Repairs did not solve the issue, slight improvement but stuttering continues. Now they say that to resolve this the transfer case would need replaced !! This car has 52,000 miles on it! …”
