Engine oil pump failure. The housing for the oil pump is made out of plastic and know to fail due to the part turning brittle in the engine surrounded by oil and heat. The oil pump housing has cracked causing a failure at the pump housing. The results are catastrophic engine failure as well as not being able to read engine oil levels on bmw idrive system.

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

The contact owns a 2010 BMW X5. The contact stated that while driving at an undisclosed speed, the vehicle stalled and was pulled over to the side of the road. There was no warning light illuminated. The vehicle was towed to be repaired under the federal safety agency Campaign Number: 23V707000 (Engine and Engine Cooling); however, after the recall repair was performed, the vehicle failed to start. The contact stated that the recall repair indicated that a diagnostic test was required to determine that an engine failure was a direct result of a fractured VANOS bolt. The contact stated that the dealer declined a diagnostic test or the repair. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 135,000.

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

The contact owns a 2026 BMW X5. The contact stated that while attempting to start the vehicle, several warning lights illuminated, and the steering wheel seized. The vehicle was towed to the dealer, where it was diagnosed with an incomplete software update. The contact was informed that the software update needed to be performed. The vehicle was repaired. The contact was dissatisfied with the failure and the diagnostic result. In addition, the contact stated that the system should have reverted to the original software. In addition, the contact stated that if the vehicle was in drive, the failure could have resulted in a serious situation. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 3,000.

The engine oil pump failed internally. The vehicle is equipped with a factory-installed variable-displacement oil pump that utilizes an internal thermoplastic adjusting ring. Due to heat cycles and mechanical stress, this plastic component degrades, becomes brittle, and catastrophically shatters or cracks.The first symptom appeared when the vehicle became entirely unable to complete an electronic engine oil level measurement via the iDrive system, consistently freezing and aborting the test at approximately 15% to 20%. This defect directly compromises road safety. A sudden drop in oil pressure causes severe internal engine friction, leading to immediate engine seizure or a total loss of motive power without adequate warning. Experiencing a sudden engine stall while driving at highway speeds places the driver, passengers, and surrounding motorists at extreme risk of a high-speed rear-end collision. Furthermore, a total engine shutdown disables power-assist steering and braking, making the vehicle incredibly difficult to control and maneuver to safety. Catastrophic mechanical failure from oil starvation also presents a severe under-hood fire hazard if oil leaks onto hot exhaust components.The problem has been officially reproduced and confirmed. The vehicle was brought to Bavarian Werkstatte, where certified technicians diagnosed the issue as an internal structural failure of the variable-displacement oil pump's plastic adjusting ring. The component is currently available for inspection upon request. BMW is fully aware of this defective design. They updated this exact component in mid-2020 to an all-metal oil pump to prevent plastic fragmentation. Despite knowing that the 2019 thermoplastic rings degrade, become brittle, and shatter under normal operating heat cycles, the manufacturer has failed to issue a safety recall in the United States, leaving drivers exposed to dangerous sudden engine failure.

I am reporting a safety concern involving a 2019 BMW X5 that experienced a sudden and catastrophic engine failure at approximately 75,000–80,000 miles. The failure occurred without any prior warning indicators, dashboard alerts, or fault codes. The vehicle lost engine function and required inspection by an authorized BMW dealership. The dealership documented internal engine damage, including metallic debris in the oil system, oil contamination, and bottom-end engine knocking. A full engine replacement was recommended. This raises safety concerns because: The failure occurred without warning Sudden engine failure could create hazardous driving conditions depending on speed and location There may be a broader pattern of similar failures BMW of North America has denied assistance and has not provided any explanation for the cause of the failure. I am submitting this complaint so the incident can be recorded and evaluated as part of any potential defect investigation.

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.
