2020 BMW X5

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 am reporting a safety concern involving BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019–2021. These vehicles utilize a variable-displacement engine oil pump containing an internal thermoplastic adjusting component responsible for regulating oil pressure. Field failures are increasingly being reported in which this internal component fractures, resulting in sudden loss or instability of engine oil pressure. The failure frequently occurs during cold-start operation in low ambient temperatures. When the component fails, oil pressure regulation becomes erratic or is lost entirely. In many cases, drivers receive little or no actionable warning prior to engine damage or vehicle disablement. Reported precursor symptoms include inability to electronically measure engine oil level, abnormal oil pressure behavior, or sudden drivetrain malfunction warnings. Failures may rapidly progress to engine shutdown or severe mechanical damage caused by oil starvation. Loss of lubrication can cause the vehicle to become disabled without warning while driving or shortly after startup. This creates a safety hazard, particularly when vehicles become immobilized in active traffic or during winter conditions the cold is when they fail the most, where occupants may be exposed to freezing temperatures while awaiting assistance. Replacement of the oil pump requires extensive disassembly of the vehicle and repairs commonly exceed $6,000–$8,000 for just the pump, assuming the motor is unharmed. Owners are currently unable to determine whether their vehicles contain the original thermoplastic oil pump design or a later revised version utilizing metal internal components, as VIN-based parts information now identifies updated components in the car even when no replacement has occurred and the old components are actually in the car. Also, BMW has actively removed the plastic part number out of all dealer networks as well. Failures have be

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 the vehicle was parked, there was fluid and lubricant on the ground underneath the vehicle. No warning lights were illuminated. The vehicle was taken to the dealer where it was diagnosed with a detached front differential shaft bearing. In addition, the contact was informed that the front differential shaft bearing caused excessive play in the propeller shaft. The contact was informed that the front differential shaft bearing needed to be replaced. The vehicle was not repaired. The contact stated that the failure was a known failure with the vehicle. The contact stated that the vehicle was serviced by the dealer seven weeks prior to the failure. The manufacturer was made aware of the failure but provided no assistance. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was unknown.

I am submitting this correspondence as a formal notification of a potential safety-related defect affecting BMW vehicles equipped with the B58 Technical Update (B58TU) engine platform, most commonly model years 2019–2021. The purpose of this communication is to request immediate review under BMW’s vehicle safety defect evaluation process due to an increasing number of oil pump failures capable of causing sudden loss of engine lubrication, unexpected vehicle disablement, and occupant exposure to hazardous conditions. The original B58 engine (B58B30M0, 2015–2017) utilized a conventional mechanically robust gerotor oil pump with predominantly metallic internal construction and demonstrated strong reliability in field operation. This component, constructed from reinforced thermoplastics including PA66-GF materials, operates within a chemically aggressive and thermally cyclic environment involving continuous exposure to engine oil additives, fuel dilution, condensation, and repeated heat cycling. While acceptable under accelerated validation testing, real-world operating conditions increasingly demonstrate premature degradation consistent with polymer embrittlement and fracture. Documented owner and technician reports indicate that under cold-start conditions — particularly in sub-freezing climates — elevated oil viscosity and startup load impose increased mechanical stress on the thermoplastic carrier. Fracture of this internal component allows debris intrusion into the pump mechanism, resulting in unstable oil pressure regulation. Commonly reported precursor symptoms include: • Inability to perform electronic oil level measurement via iDrive • Erratic or oscillating oil pressure behavior • Intermittent lubrication warnings or absence of warning prior to failure • Rapid progression to bearing damage and engine seizure Given the potential for sudden vehicle disablement without adequate warning, I respectfully request BMW of North America initiate a formal inquiry

The dealer was contacted and confirmed that parts were not yet available for the recall repair. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

Was driving at normal interstate speed when I received a warning on my dashboard to pull over and turn off engine —- low engine pressure, immediately. Call a tow. I immediately pulled over, turned off my car and contacted a tow. My vehicle was towed to the BMW dealership. I received an update that my oil pump failed. It’s almost $6k to replace and then stated not sure if that’ll truly fix the problem and to change the engine $28k. I began to do research and this is a known problem. Many owners have this problem- BMW is aware and began change the plastic part to metal in the subsequent years. I received no warning that it was beginning to fail and it is a safety hazard as I was on the interstate at the time.

The local dealer was contacted and confirmed that parts were not available. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the issue; however, no assistance was provided. The contact had not experienced a failure.

Vehicle has excessive condensation in driver headlight. Garage kept only. Problem discovered because of parking vehicle outside on driveway while the garage hosted moving boxes. This was the only time this vehicle has spent the night outside.

While driving through west Los Angeles, the vehicle suddenly began emitting white smoke from the engine compartment. There were no prior warning lights, messages, or symptoms indicating a problem. The smoke quickly intensified and turned dark. Thick smoke filled the air, and the cockpit, with the smell of toxic fumes. I safely maneuvered to the shoulder and exited the vehicle with my passenger. Flames erupted from the front of the vehicle. We called 911, which dispatched the fire department. The LAFD responded, cutting open the hood in order to extinguish the fire. The vehicle was towed to a yard following the incident. The vehicle and its contents were declared a total loss.   BWM North America dispatched a technician to inspect the vehicle. After inspection, the manufacturer indicated that the starter was the source of the fire. At the time of the incident, the vehicle was subject to a safety recall related to the starter with no remedy available. The failure occurred without warning. Both occupants were exposed to heavy smoke.

Sunroof - explosion of glass while driving down the road. No other cars or anything that would cause flying debris. I decided to file this report after reading of multiple accounts being reported.

The contact owns a 2020 BMW X5. The contact received notification of NHTSA Campaign Number: 25V644000 (ELECTRICAL SYSTEM); however, the part to do the recall repair was not yet available. The contact stated that the vehicle failed to start. After several attempts, the vehicle started. The check control master warning light was illuminated. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The failure mileage was approximately 120,000.

Starter can malfunction and start fire. Unable to park in garage due to potential fire risk. BMW is aware of the problem. Care was serviced at BMW dealer and said that they have no remedy. This recall is over 15 months old.

The safety risk arises from inaccurate federal recall records maintained by BMW of North America. My vehicle had a safety recall for starter replacement (Recall 25V-644). This recall repair was already completed by an authorized BMW dealer, and the starter was replaced under warranty. However, BMW continues to list the recall as OPEN with “Remedy Not Available.” This creates a safety risk because inaccurate recall records may lead to improper vehicle safety status, incorrect regulatory reporting, and potential refusal of assistance if a starter-related failure or no-start condition occurs in the future. The problem has been confirmed by an authorized BMW dealer, and I have official service documentation showing that the recall repair was completed. The vehicle was inspected and repaired by BMW of Gwinnett Place. No warning lights were present after the repair. This complaint is not about a new mechanical failure, but about BMW’s failure to accurately update and close a completed safety recall, which misrepresents the vehicle’s safety status.

The contact owns a 2020 BMW X5. The contact stated while driving approximately 25 MPH, the message "Low Oil Pressure - Stop Vehicle Immediately" was displayed, and the oil warning light was illuminated. The vehicle was pulled over to the side of the road and turned off. The vehicle was towed to a dealer where it was diagnosed and determined that the oil pump was inoperable and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 81,000.

Recall 19v-631, I am experiencing a faulty steering issue as reported in the recall. My vehicle was in production around the same time as the recall vehicles.
