I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it fails, oil pressure becomes erratic or is lost entirely, often with little to no warning before engine damage or vehicle disablement. Warning signs, when present, include inability to measure oil level electronically, abnormal oil pressure, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs 6,000-8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

My 2020 BMW X5 sDrive40i has experienced recurring and serious electrical, shutdown, and drivability problems that have not been resolved despite BMW service and a recall-related repair. The vehicle has unexpectedly restarted after being turned off and has also failed to shut down properly. On September 6, 2026, after being parked at Costco for approximately 40–60 minutes, I returned to find the vehicle off but not secured. The brake lights were on, the windows were down even though I had left them up, and the interior systems were operating. The radio was playing an unfamiliar station, although I do not listen to the radio. I documented this on video. Later that same day at Whole Foods, after parking, turning the vehicle off, and getting out to retrieve my dogs, the vehicle appeared to still be running. Video captured the engine running for approximately one second. I shut it off and locked it, but the vehicle then unlocked itself, also captured on video. These were two separate incidents within nine days, occurring after BMW performed a recall-related repair intended to address unexpected vehicle reactivation. In addition, the vehicle has twice shut off unexpectedly while accelerating on the freeway. These incidents, combined with the unexpected restarting, failure to shut down, windows opening, and vehicle unlocking itself, create serious safety concerns. I purchased this vehicle specifically to transport my dogs. If the vehicle can unlock itself or lower the windows while I am away, my dogs could escape or be exposed to being taken. I no longer have confidence that the vehicle will remain safely shut down and secured when I leave it. The recurring nature of these failures and the fact that they have continued after BMW’s attempted repair require a thorough investigation and permanent resolution. I am requesting that BMW review the complete history and consider repurchase or replacement if the defect cannot be permanently corrected.

2020 BMX X5 xDrive40i experienced recall issue 24V-104. Year of vehicle is not included in recall 24V-104. I did not receive a notice of recall issue 24V-104. This recall should be extended to additional Years of this model of vehicle. Was driving in traffic on a state highway. Utilized breaks to stop the vehicle and brakes failed. Received warning notices through the cars system that aligned exactly with the errors expected to be received in Recall 24V-104. If I had been driving at a higher speed, I would not have been able to stop the vehicle and would have crashed into the vehicle in front of me at a high rate of speed, causing grave harm to myself and any individuals in the car ahead of me - and potentially any other car/individuals that were around me. The vehicle was inspected by an independent service center, which confirmed that brake failure was identical to current recall 24V-104. Auto shop only found out about the recall because they attempted to order new part and was informed that part could not be sold due to recall. Recall did not appear when VIN was searched. The problem was confirmed by the independent service center. There were no prior warnings, messages, or other systems of this problem prior to the failure and this is the first time it was experienced.
