2020 BMW X5 Engine

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.

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

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 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.

Dear NHTSA, I am writing to report an issue with my vehicle, VIN: [XXX] , which appears to be related to a recall program. My dealer, BMW of Sherman Oaks #488, refuses to acknowledge the connection between the starter failure and the recall despite clear indications of this connection. I kindly request your assistance in investigating this matter and ensuring that the dealer complies with the recall requirements and provides the necessary corrective action. Thank you for your prompt attention to this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

[XXX] my engine started stopped working even several times of trying the SUV didn’t star I took it to BMW Braman Miami center to fix the problem I was charged $3,997.18 since it wasn’t a recap of the engine starter yet I called my advisor Nasser Darwich for the recall reimburse after I get the letter from BMW USA & he told me it was no reimbursement INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

cHECK ENGINE LIGHT IS ON AND BASED ON THE CODE THERE IS A PROBLEM WITH THE ACTIVE GRILL SHUTTERS. i DID SOME RESEARCH AND SEEMS THIS IS A COMMON PROBLEM WHERE THE ACTUATOR MOTOR MAY BE THE PROBLEM
