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. On 5/22/2018 (pm) upon starting the vehicle it ran rough. We tried to stop and restart but it did not correct the problem. On 5/23/18 (am) the vehicle started properly and was taken into to the dealer to diagnose the problem. On each occasion noted above the display screen prompts with the drivetrain malfunction message, but checking the on-board vehicle status all systems are "ok". Reduced power and/or complete loss of power in a critical situation could prove to be disastrous. Considering the number of complaints and potential risk the factory should elevate this complaint to a recall status before someone is seriously hurt (if that hasn't already happened).

While driving, suddenly the car will start shaking with immediate loss of power and the engine light comes on. The main screen displays "drivetrain malfunction: drive moderately. Maximum drivetrain output not available. Consult service center" during the malfunction the car has significant shaking, loses nearly most power and the car must come to an immediate stop andthe engine needs to be turned off. Bmw does not have a fix to resolve the issue and every time it happens they replace different parts. This is the 3rd time it happened since I purcased the car and it is a major safety issue especially while driving on a highway.

While driving, the car will have a sudden shake, an immediate loss of power and the engine light comes on. The main radio screen displays a drivetrain malfunction, reduced power, immediate service. During this time the car has significant and sustained shaking and loses nearly all forward power. The car must come to an immediate stop and turned off. If you were passing or on a busy highway, this could likely lead to a car accident with no ability to avoid it since the car has little to no power. There are scores of complaints online about this for the 650i gran coupe. There are also youtube postings. The owners have posted that they cannot find the issue. Dealers have reprogrammed the ecu, replaced spark plugs, replaced coils, replaced fuel injectors and replaced fuel pumps. Even with this, the cars continue to have the same issue, which could easily cause an accident. The federal safety agency, since bmw has repurchased dozens of bmw 650i gran coupe cars because of this, they are clearly aware of the fault. There are dozens and dozens of posts online and on youtube, this is a well known issue. Yet bmw does not have a single fix to resolve the issue. Please help us resolve this issue before someone gets killed or injured, unless someone else already has.
