2019 BMW X5: engine stalls while driving

Filed Sep 7, 2026 · Engine · PA

The BMW B58 Technical Update (B58TU) engine utilizes a variable-displacement oil pump incorporating internal components manufactured from thermoplastic rather than traditional metal. These plastic internal parts are prone to severe thermal degradation and brittleness over time. Under normal operating conditions—and particularly during cold-starts in low ambient temperatures—the plastic elements suffer structural fatigue and catastrophically fracture, destroying the pump's ability to maintain oil pressure. A primary indicator of failure is the vehicle's inability to complete an electronic oil level measurement, quickly followed by a critical "Low Oil Pressure: Stop Engine" warning. This defect poses an immediate and severe hazard to motor vehicle safety. A sudden loss of engine oil pressure while traveling at highway speeds results in immediate oil starvation and catastrophic engine seizure. This causes a sudden loss of motive power and can lead to a loss of power-assisted steering and braking. Operating a vehicle that suddenly stalls or seizes in fast-moving traffic creates an extreme risk of high-speed rear-end collisions and leaves occupants stranded in highly hazardous highway conditions. Because BMW quietly transitioned back to a ruggedized metal oil pump design in later production runs without issuing a safety recall or notice for earlier models, thousands of vehicles remain on the road with an inherently defective, safety-critical engine component. I request that the federal safety agency open a formal safety defect investigation into this component to mandate a safety recall and protect the public.

The contact’s wife who owns a 2019 BMW X5. The contact stated that while the vehicle was parked, there was an abnormal sound and the vehicle intermittently stalled. No warning lights were illuminated. The failure had occurred on several occasions. The vehicle was taken to an independent mechanic, where it was diagnosed and determined that the starter needed to be replaced. The vehicle was not repaired and was taken back to the residence. The contact stated that the vehicle stalled again and failed to return to normal operation. A dealer was contacted; however, the vehicle was not yet diagnosed or repaired. The contact researched and was made aware of an unknown recall; however, the VIN was not under recall. The manufacturer was not notified of the failure. The failure mileage was approximately 79,000.

I always service and baby my vehicle. Had recently got starter recall & fresh oil change done 2 months at my local BMW Atlantic City NJ dealership. On June 27th, as I was driving the vehicle normally a message popped on the dash stating engine oil is at a minimum level, add 1 liter of engine oil, refill oil immediately. So I went to my earliest autozone bought quart of mobile 1 oil and refilled it. After that the warning message went away and came felt fine. Unfortunately the next day same message popped up, so drove over to BMW service to get diagnosed. Due to the computer system in the vehicle not being able to read the oil level measurement. It would go from 0-18% oil level reading then message would pop up saying unable to read to try again or make sure vehicle is on ground level which I made sure it was. So next day I dropped it off at BMW dealership for diagnosing. After 1 day and half they came to the conclusion that it is a bad oil pump and wants to charge $6,362.31 for repairs. Advisor stated its due to older gen bmw b58 engines using plastic oil pumps inside which causes to break and cause leaks. So they are aware its an common issue but won’t do an recall or service bulletin to fix issue which is very dangerous because the engine could seize up and stall anytime I’m driving around due to not knowing the oil level measurements. It is super risky and unfair for consumers to pay for such a big bill repair. I hope there is recalls or something to help remedy this cause for current & future BMW affected vehicles. BMW is aware of this issue but won’t resolve it.

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.

vehicle has been vibrating at low speeds when turning or when backing up. Took vehicle to BMW dealership (BMW of Nashville in Franklin, TN) multiple times during the past 18 months without resolution. On my visit for the same issue this month, dealership finally recognized the issue and said there was a BMW bulletin out about the issue SIB 27 02 20. It is very frustrating that 1. The dealership kept stalling and despite test driving the car with me and feeling the vibration, they kept blaming tires or saying it was normal while the bulletin about the issues was generated in 05.20.2020 2. It cost me over $627 for them to change the transfer case oil to diagnose and repair the issue. I am still in the testing phase after the transfer case oil change as the vehicle needs to be driven 300+ miles. The dealership and BMW should issue a recall since it is a know issue that the wrong oil was used in the manufacturing process and reimburse the cost charged for diagnostic and transfer case oil replacement. The vehicle is furthermore still under warranty so I should not be paying anything for diagnostics or repairs.

The contact's husband owns a 2019 BMW X5. The contact stated while her husband was at a complete stop at the red traffic light, the vehicle stalled. The vehicle failed to restart and was towed to the dealer, where it was diagnosed that the starter had failed and needed to be replaced. The vehicle was repaired at the contact's expense. The contact later received notification of the federal safety agency Campaign Number:Â 24V576000Â (Electrical System, Engine and Engine Cooling), which the contact related to the failure. The vehicle was taken to the dealer, where the recall repair was completed. Additionally, the dealer was contacted for reimbursement regarding the expenses sustained due to a failure related to the safety recall, but did not provide assistance. The manufacturer was not notified of the failure. The failure mileage was 84,433.
