2020 BMW X5: engine failure

Filed Aug 25, 2026 · Engine · NY

The oil level reading is failing at 16% due to an oil pump malfunction. BMW has addressed this on all 2022+ b58 engine but all prior years have the plastic failing oil pump. The had to upgrade it because it cause catastrophic failure to the engine. It creates oil pressure with plastic parts and was upgraded to all metal in 2022. There should be a recall for this part since it can cause catastrophic engine failure at any point anywhere while driving at any speed, slow, fast, speed limit. Doesn’t matter the part can fail and injure or kill people

It’s a common issue between 2019-2020 where the oil pump which came from factory has plastic impellers which crack/disintegrate causing catastrophic failure to the engine disabling the vehicle the only warning signs before this happens is you cant read oil level and or the car prompts with a warning low oil messages if untreated the car will have catastrophic engine failure with little to no warning the car was mass produced and this is a common issue therefore should be recalled

Plastic oil pump cracking problem is apparently known to BMW, but they haven’t recalled these defective oil pumps leading to engine failure.

Safety Hazard: Oil Pump Failure Leading to Sudden Engine Stall (BMW B58TU engines) Description of Defect: The oil pump module in the 2020 BMW X5 (G05) contains internal plastic components that are prone to thermal degradation and premature failure. These plastic parts can crack or disintegrate, causing a sudden loss of oil pressure. Safety Risk: A failure of the oil pump leads to insufficient lubrication of critical engine components, which can result in a sudden and complete engine seizure while the vehicle is in motion. This causes an immediate loss of propulsion and power steering assist, significantly increasing the risk of a high-speed collision or being stranded in dangerous traffic conditions. Additional Note: This is a known mechanical defect where a critical engine component (oil pump) relies on non-durable plastic materials, creating an unreasonable safety risk for drivers and passengers due to potential catastrophic engine failure without prior warning.

I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine (primarily 2019–2021 models). These vehicles use an oil pump containing an internal plastic component that regulates oil pressure. This plastic part is fracturing in the field, leading to sudden loss or instability of oil pressure. Failures commonly occur during cold starts in low temperatures. When the component 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 behavior, or sudden drivetrain malfunction warnings. These can quickly progress to engine shutdown or severe engine damage due to oil starvation. My vehicle is currently experiencing all of the described oil pump-related symptoms, including inconsistent electronic oil level readings and drivetrain malfunction warnings consistent with oil pressure instability. This condition creates a serious safety risk. The vehicle can become disabled without warning while driving or shortly after startup. Oil starvation can lead to catastrophic engine failure, especially at highway speeds, where sudden engine shutdown or seizure increases the risk of a crash. Failures are particularly dangerous in winter conditions, when vehicles may become immobilized in traffic or freezing temperatures. Replacement of the pump requires major disassembly and typically costs $6,000–$8,000, assuming no engine damage. Owners cannot determine whether their vehicle has the original plastic component or a revised metal version. BMW’s VIN-based parts lookup now shows only updated components even when original plastic parts remain installed, and the original plastic part number has been removed from dealer systems. Because this defect can cause sudden vehicle disablement and potential catastrophic engine failure without adequate warning.

The contact owns a 2020 BMW X5. The contact stated that while at a complete stop, the START/STOP feature failed to operate as designed, and the engine failed to restart while depressing the accelerator pedal. The contact stated that a "Starting Engine Possibly Shortly: System Overheated. Restarting Engine Possible After Cooling" message was displayed on the instrument panel. After the contact allowed the engine to cool down, the vehicle failed to restart with the same messages displayed. Due to the failure, the vehicle was towed to the dealer where it remained. Upon investigation, the contact discovered the federal safety agency Campaign Number: 24V576000 (Electrical System, Engine and Engine Cooling); however, the VIN was not included in the recall. The contact also discovered and linked the failure to Technical Service Bulletin: B120424. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 73,000.

The contact owns a 2020 BMW X5. The contact stated while at a stop light, the gear shifter independently shifted into neutral. The contact stated after several attempts, the gear shifter was shifted into park. The contact stated that the gear shifter had seized in park(P). The vehicle was towed to the dealer where it was diagnosed with internal starter motor shortage. The contact was informed that the starter motor needed to be replaced. The vehicle was not repaired. The contact was informed of the federal safety agency Campaign Number: 24V576000 (Electrical System, Engine and Engine Cooling); however, the VIN was not included in the recall. Additionally, the contact stated that the failure had occurred at night, while the four minor children were inside the vehicle. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was unknown.
