Transmission & Drivetrain complaints by model year
The left hydraulic engine motor mount (P/N 22117581621) completely collapsed and failed at 6 years and only 24,811 miles. The right mount was also replaced at the same time (P/N 22117581622). The failure allows unsafe, excessive engine movement and shifting under rotational torque loads. This shifting creates an immediate safety hazard, risking the sudden compromise of surrounding mechanical systems, cooling lines, and electrical harnesses while the vehicle is in motion. BMW North America acknowledged the premature nature of the failure by approving a goodwill repair for the labor costs but forced me to pay out-of-pocket for the defective parts. The engine mount issue was detected when the vehicle went in for normal services and the known recall for the engine starter which had the potential to cause bodily harm as well as property harm due to fire risk, even when the engine was off.

NHTSA complaint #11720158 — an unverified report by a vehicle owner.
I am reporting a premature failure of two critical engine components: the Heat Management Module (Coolant Pump/Thermostat assembly) and the Oil Filter Housing. Despite the vehicle's low mileage (40,000 miles), the Heat Management Module began leaking coolant, posing a significant risk of engine overheating and sudden loss of power while driving. Simultaneously, the Oil Filter Housing has developed a leak, allowing oil to seep onto the engine block and potentially onto the serpentine belt. Both failures represent a safety hazard: Coolant Leak: Risk of thermal engine damage and being stranded in traffic due to overheating. Oil Leak: Risk of oil contacting hot exhaust components (fire hazard) or causing the serpentine belt to slip/fail, resulting in a sudden loss of power steering and charging systems. These components appear to have failed due to manufacturing or material defects rather than standard wear and tear for a vehicle of this age and mileage
NHTSA complaint #11718383 — an unverified report by a vehicle owner.
The contact owns a 2019 BMW 330I. The contact recently purchased the vehicle. The contact received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The contact stated while driving 60 MPH, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The message "Drivetrain Malfunction" was displayed. The contact stated that on a separate occasion, when the vehicle was started, the vehicle vibrated and jerked abnormally with several unknown warning lights illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The failure became progressively worse, and the vehicle was no longer being driven. The manufacturer was not made aware of the failure. The approximate failure mileage was 54,000.
NHTSA complaint #11704226 — an unverified report by a vehicle owner.
While traveling at approximately 20 mph, the vehicle experienced a sudden loud pop from the engine bay, immediately followed by multiple dashboard warning lights. The vehicle was safely brought to a stop, and AAA was contacted to arrange towing to the nearest available repair facility. A diagnostic inspection identified the failure of the crankshaft vibration damper. According to the repair facility, this component is essential to maintaining the structural integrity and operational balance of the engine. At the time of failure, the vehicle had approximately 37,000 miles on the odometer—well below the expected service life of such a critical part. Had this failure occurred at highway speeds, the resulting mechanical disruption could have led to a loss of engine function and increased the risk of a serious accident or death. The nature and mileage of this failure raise concerns about a potential defect or design flaw. I am requesting that the National Highway Traffic Safety Administration review this incident and consider whether similar cases have been reported. Failures of this type should be reviewed for broader safety implications.
NHTSA complaint #11664246 — an unverified report by a vehicle owner.
Multiple codes came on right after I had gotten my thermostat and my water pump fixed. However it ended up being that there was more leaks throughout the rest of the car. The car has currently cost me $3400 to fix and it’s still not fixed because nobody can figure out where the actual leak is coming from. The coolant is leaking and nobody can figure out where, it’s been having jerking issues since it started leaking and I read on other Bmw’s that the coolant leaks into the head gasket, causing the engine to blow
NHTSA complaint #11569599 — an unverified report by a vehicle owner.
We had a 2017 bmw 330i x-drive. It had approximately 67000 miles. The car stalled while driving about 6 times. The first time was in 3/2021. The diagnostics were for a faulty high pressure fuel pump. We replaced the HPFP. It stalled again while driving. The diagnostics were for a faulty low pressure fuel pump. We replaced this. The car then stalled while driving 2 more times. The car stalled again in 10/2021, and we towed it to the dealer, who diagnosed a problem with the electric fuel pump control unit., which the dealer replaced. We brought the car home for one day, and we had the same problem again. We brought the car back to the BMW dealer, who diagnosed a problem with the VANOS system. The BMW Peabody dealer directed us to BMW corporate for evaluation of available warranties and rebates given the nature of the problem (VANOS) being warranted under the California SULEV emissions standards and the fact that they dealer had diagnosed a separate problem the day before. We sent the diagnostics and the SULEV warranty info to Sean, as everyone at BMW seemed unaware of its existence and who was responsible for following it. He took weeks “looking into it,” and the dealer repaired the VANOS during this time without a final answer from corporate. A car stopping while driving is clearly dangerous to the occupants and surrounding vehicles. BMW did not honor the SULEV warranty, which clearly covers the VANOS and the fuel pumps until 70000 miles. The car was traded to BMW Peabody, as we no longer felt safe driving it. We do not know if the replacement of the VANOS fixed the problem.

Water pump keeps going bad 2nd time replacing in 2 years rough idle and failed part problems that BMW service team does not understand. Vehicle has stalled at 0 rpm I'm thinking there is an issue with the engine also reported by previous owner and I also have the same complaints, as well the foot release which I was was told was an option never worked. Please search vin [XXX] for all incident reports with this vehicle. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
NHTSA complaint #11461947 — an unverified report by a vehicle owner.
Engine Wiring is made of Soy products with attracts Rodents to feed and destroy the wiring. When this occurs it puts the driver ad passengers in danger because certain functions such as brake light, Headlights and windshield wipers may not work properly. This is becasue when the wiring is compromised , circuits are broken which causes the vehicle's systems connected to that circuit to partially or completely fail, Rending a vehicle partially or completely inoperable. The vehicle was inspected the the BMW dealership service center and they confirmed it was rodent damage . Geico insurance also inspected the vehicle. The vehicle started to restrict engine performance and the Engine service light came on stating there was a Drive Tran malfunction.

car had 1,645 miles rear left axle broke. Car would not move. Had this occurred on a highway I easily could have been rear ended. Part must have been defective, Dealer replaced the part left rear CV joint but not the right, nor did the dealer confirm both rear axles were not from the same batch. The failure was catastrophic and sudden with no warnings.

I BOUGHT MY BMW 330I E46 2002 5 YEARS AGO AND NOTICED THE CHECK ENGINE LIGHT COME ON AFTER THE FIRST DRIVE. AFTER TAKING IT IN TO THE MECHANIC I WAS TOLD THE CODE THAT THREW THE LIGHT ON WAS (P0741). I HAVE DONE MY RESEARCH AND HAVE DETERMINED THAT THIS IS A WIDESPREAD PROBLEM FOR THESE CARS. THE RESULTS HAVE BEEN HORRIBLE GAS MILAGE, HARD SHIFTING AT TIMES AND MOST LIKELY SHORTENED TRANSMISSION LIFE. THIS PROBLEM AS HAS CAUSE MY CAR TO NOT BE ABLE TO PASS SMOG!

WHILE ACCELERATING, THE ENTIRE CAR SHAKES VIOLENTLY BETWEEN 20-30 MPH. THIS DOES NOT OCCUR AT ANY OTHER SPEED AND IS MORE PRONOUNCE GOING UPHILL THAN DOWN. BROUGHT THE CAR IN AND WAS TOLD IT WAS A BROKEN ENGINE MOUNT. THIS SAME PROBLEM WAS REPAIRED 2 YEARS AGO (JUNE 2013) FOR THE EXACT SAME THING. THIS SHOULD NOT BE A REOCCURING ISSUE. REPAIR WAS NOT MADE AND CAR IS CURRENTLY PARKED AS CAR MAY CAUSE SERIOUS ACCIDENT IN CITY DRIVING WITH MULTIPLE STOPS AND STARTS.
