What owners report
The contact owns a 2021 BMW X3. The contact stated that upon refueling the vehicle and attempting to start the vehicle, the vehicle failed to start on several occasions. The contact stated that the vehicle was able to restart after several attempts. The vehicle was taken to Auto Zone, where DTC: P0172 and P0446 were retrieved.

This technical failure in the BMW B58TU engine (2019-2021) involves the variable-displacement oil pump's internal thermoplastic slide. In low ambient temperatures, the high viscosity of cold oil creates mechanical stress that causes this plastic component to fracture. The Safety Hazard The primary risk is a sudden loss of motive power. When the slide fails, oil pressure becomes unregulated or drops entirely, triggering an immediate "Drivetrain Malfunction" or engine shutdown. Immobilization: Vehicles may stall in active traffic or high-speed environments without sufficient warning. Environmental Risk: Failures peak in extreme cold, leaving occupants stranded in freezing conditions while awaiting recovery. …
Component Failed: Engine starter relay and starter motor assembly. The vehicle stalled in traffic and ignited upon a restart attempt. The vehicle is a total loss, currently held by [Insurance Co] at [Location/Lot #], and is available for inspection. Safety Risk: The driver's life was at immediate risk. The vehicle stalled in active traffic, creating a collision hazard, followed by a rapid, uncontrollable engine fire. The driver suffered smoke inhalation and severe trauma while escaping. A delayed exit would have been fatal. Confirmed by Dealer: The failure mirrors the defect pattern in Recall 25V-636 (Starter Relay Corrosion). While the fire prevents reproduction, the vehicle had a consistent service history with no prior electrical issues. Inspected By: The vehicle was inspected by [Insurance Co] and declared a total loss. [Optional: The Fire Dept. responded under Report #[Number]]. …

The failure mileage was approximately 70,000.
On Sept 16th, 2026 my wife was operating the vehicle under normal, routine driving conditions. While she was completely stopped at a stop sign the vehicle spontaneously caught fire. Description of the Issue and Damage: 1. There was no collision, impact, or external trauma prior to the fire. 2. There were no check engine lights, overheating warnings, or malfunction indicators on the dashboard leading up to this event. 3. The vehicle has been properly maintained and unmodified. 4. The fire originated spontaneously within the engine compartment. As documented in the attached photographs, the thermal event was heavily concentrated on the passenger side of the engine bay. 5. …
On returning to my locked vehicle that had been in the parking ramp for 3 days, I started the car and the display message indicated that my vehicle was completely out of gas and the oil was very low. The vehicle had nearly a full tank of gas when it was parked. The vehicle was towed to the dealership who assessed the vehicle. The service department indicated that the vehicle likely did not sound like it was running because of the idle feature, and as such, I may have thought I shut off the car, but that eventually the idle feature turned off, and the vehicle ran while it was locked until it was out of gas. The service man who sent me a video of my vehicle and described what happened, also showed me another BMW SUV in the hoist next to my vehicle and indicated that same vehicle had the same thing happen as well. …

The vehicle was towed to an independent mechanic, who diagnosed a failure with the fuel pump. The vehicle was repaired, but the failure reoccurred. The vehicle was then towed to an independent mechanic, who diagnosed a failure with the fuel pump and fuel control module regulator wiring harness. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA Campaign Number: 21V586000 (Fuel System, Diesel); but the VIN was not included. …
