NHTSA complaint #11722428 — an unverified report by a vehicle owner.

ENGINE

Vehicle abruptly shut off while reversing out of my driveway. Vehicle restarted after a long crank and appeared to enter a reduced power mode/limp mode with a transmission fault that locked the transmission in 4th gear. Reading OBD2 codes revealed a code for the crankshaft position sensor. Inspection of the 3 terminal sensor revealed 2 of the terminal contacts on the sensor to be shorted out with melted plastic on both the sensor and the wiring connector plug. Shorted wire could be a result of a leaking coolant passage at rear of engine within bellhousing where sensor is located. Coolant intrusion into sensor connector resulted in electrical short and melted connections.

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.

ENGINE

On 11/10/21 I was advised by Long Beach BMW (Long Beach, CA) that my car needs a new engine. The car smells of gas (both when running and when sitting) and burns excessive amounts of oil. The car requires a quart of oil every 200 - 400 miles. The first engine was replaced after only 77,000 miles because the car was stalling unexpectedly. Now, the current engine needs to be replaced after only 51,000 miles because the car smells of gas (likely because the fuel injection system is not working properly) and because it is burning excessive amounts of oil. BMW expects me to cover the cost of a new engine even thought there is an obvious defect. I contacted BMW of North America and they offered to take the car back & give me $2000 toward a new car. There is currently a recall because of engines at risk of blowing up but for some reason, my car does not appear to be part of that recall. https://abcnews.go.com/amp/US/wireStory/bmw-recalls-vehicles-3rd-time-due-engine-fire-83338862 BMW has been notified of the defects with this car and has diagnosed the defective engine but refuses to replace the engine at their cost as part of the current recall. Instead, the car remains a hazard at risk of catching fire. BMW's negligence is placing me, my family & other travelers at risk of harm or death because they know of the problem & will not address it. This is the 2nd complaint that I've sent to the NHTSA (the first on 9/13/21) and now there is a recall & so the NHTSA is aware of the problem as well.

ENGINE

My car died in an intersection unexpectedly as if my battery had died. My infant was in the backseat. This was suck a busy intersection that police dept had to park behind me to keep me from being hit. The car could not be put in neutral to move it out of the way. After over an hour we were able to restart the car and excessive battery discharge message displayed. This is on top of me taking it to the dealership for excessive oil consumption and BMW was aware my motor would eventually give out.

ENGINE

The vehicle is Burning a lot of oil due to the valve stem seals. Because of how the engine was designed. Since 2011 to 2018 was a law suit of the same engine since 2000 of the N62 V8 Engine of BMW. Smoke of oil comes out the exhaust and BMW cannot fix the issue they designed.

ENGINE

Engine is available for inspection upon request. Earlier this month, my 550i completely shut off at a traffic light. When attempting to restart the engine, the Starter strained very hard and smoke came out of the engine. Engine was immediately shut off and the car was towed to a local shop. In turn the shop replaced the Starter the following day and heard knocking from the engine once it turned it over. Upon examination the shop pulled open the oil filter and it was full of metal shrapnel. I feel fortunate the car was not in motion at the time of the failure, given the engine shut off with no warning this could have resulted in a catastrophic accident.
