FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER, ENGINE
Component Failed: Engine starter relay and starter motor assembly. The vehicle stalled in traffic and ignited upon a restart attempt. The vehicle is a total loss, currently held by [Insurance Co] at [Location/Lot #], and is available for inspection. Safety Risk: The driver’s life was at immediate risk. The vehicle stalled in active traffic, creating a collision hazard, followed by a rapid, uncontrollable engine fire. The driver suffered smoke inhalation and severe trauma while escaping. A delayed exit would have been fatal. Confirmed by Dealer: The failure mirrors the defect pattern in Recall 25V-636 (Starter Relay Corrosion). While the fire prevents reproduction, the vehicle had a consistent service history with no prior electrical issues. Inspected By: The vehicle was inspected by [Insurance Co] and declared a total loss. [Optional: The Fire Dept. responded under Report #[Number]]. BMW was formally notified via demand letter on [Date]. Warning Lamps/Symptoms: No prior warnings. The failure was acute. A "Drivetrain Malfunction" message appeared seconds before the stall. Smoke and flames appeared immediately upon the attempted restart.

I am reporting a driver safety concern involving BMW vehicles equipped with the B58 Technical Update (B58TU) engine in model years 2019–2021. These engines use a variable-displacement oil pump containing an internal thermoplastic adjusting component that regulates oil pressure. Field failures show this component can fracture, causing sudden loss or instability of engine oil pressure. Failures most commonly occur during cold starts in low temperatures, it can occur at any time or temperature. When the part breaks, oil pressure becomes erratic or is lost entirely. Drivers often receive little or no actionable warning before the vehicle shuts down or suffers severe engine damage. Precursor symptoms may include inability to measure engine oil level electronically, abnormal oil pressure behavior, or sudden drivetrain malfunction alerts. In many cases, the condition rapidly progresses to engine stall or mechanical failure due to oil starvation. Loss of lubrication can disable the vehicle without warning while driving or shortly after startup. This creates a serious safety hazard, especially if the vehicle stalls in active traffic. The risk is heightened in winter conditions—when failures occur most often—because occupants may be stranded in freezing temperatures while awaiting assistance. Repair requires major disassembly, and oil pump replacement alone commonly exceeds $6,000–$8,000, excluding additional engine damage Owners cannot reliably determine whether their vehicles contain the original thermoplastic oil pump design or a later revised version with metal internal components. VIN-based parts systems now default to the updated design even if no replacement has occurred, and the original plastic component part number has reportedly been removed from dealer networks. This lack of transparency prevents owners from assessing their risk. I believe this represents a known manufacturer defect with direct driver safety implications that warrants formal investigation

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 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 when engine damage occurs. 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 even when no replacement has occurred. Failures have been reported across multiple production years, and affected vehicle population boundaries remain unclear.

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
Oil pump failures have been reported across multiple production years, and affected vehicle population boundaries remain unclear. Because this condition can result in sudden vehicle disablement without adequate warning especially in the cold, I believe this issue warrants investigation as a potential safety-related defect. 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.

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. A recall should happen

ENGINE AND ENGINE COOLING
The contact owns a 2020 BMW X3. The contact stated that while driving approximately 45 MPH, the vehicle began to shake with the message, "Pull Over Engine Oil Pressure Low Pull Over Stop Driving to Avoid Engine Failure". The contact immediately pulled over to the side of the road, inspected the vehicle, and became aware there was no issue with the oil. The vehicle was towed to a certified mechanic, who diagnosed the vehicle and determined that the oil pump was defective due to the oil pump being manufactured with plastic. The mechanic confirmed it was a known issue, and the oil pumps were changed to a metal material to avoid the failure. The dealer was contacted, and the new metal pump part, PN: 11418646454, was ordered. The vehicle was scheduled to be repaired. The manufacturer was informed of the failure and informed the contact that the vehicle was purchased at a dealer not associated with BMW, and the cost of the repair would not be covered. The failure mileage was approximately 60,000.

70-80k mileage the oil filter housing gushed coolant fluid. Replacement at dealership quoted at $4,000. Dealership indicated they replace part with current part and do not upgrade to an all aluminum to prevent future problems. Employee also stated they are seeing more of these issues of late. The housing has plastic components that fail easily. There was a 2020 bulletin warning of similar failures for this type of engine and vehicle but BMW has not issued a recall. If this draining of coolant is not detected early enough, the engine could overheat and fail, creating a traffic hazard and safety concern to passengers. Local certified mechanics quoted $2,500 for replacement using an aluminum part. These two quotes were from different mechanics and were based on phone conversation, so additional charges may have applied once they began work.they both opined if part is not replaced with aluminum, the part will fail again prematurely. There is a recently filed class action lawsuit in New Jersey.

UNKNOWN OR OTHER
My 2020 BMW X3 (VIN: [XXX] ) is subject to NHTSA Recall 25V636 (urgent fire risk when parked). The remedy is not yet available for my VIN, and my dealer has only given verbal assurances with no written confirmation of repair availability. I am unable to safely park the vehicle per recall instructions. I request NHTSA assistance to ensure BMW provides a loaner, rental, or other mitigation until the recall repair can be completed.

The car has active air shutters on the grill/radiator, which are known to fail prematurely, causes overheating and emissions issues that trigger a check engine light. This was a know issue that BMW issued service bulletin and a 15 year, 150k mile warranty on the part/component up to 2019 model years. BMW did not resolve this malfunction in the same body style car in 2020, and the issue persists. BMW refuses to cover repairs on this issue that they have previously acknowledged and failed to fix, which effects the safety and drivability of the vehicle. There is a class of owners experiencing this issue who are not covered as a result of BMW failing to take accountability for the design failure in 2020+ model years. Estimated repair costs are $1,600 on average. Previous bulletin: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The variable displacement oil pump contains a plastic (Duoplex) internal adjusting ring/vane carrier that is known to become brittle and shatter. Status: While the pump has not yet suffered a total mechanical collapse, it is a documented inherent defect. The manufacturer (BMW) has already superseded this part (Original #11418646454 or ...453) with a reinforced metal version (Part #11419895359), admitting the original material was insufficient for the engine's lifespan. How was your safety or the safety of others put at risk? Risk: The failure mode is sudden and unpredictable. If the plastic ring shatters while driving, it can lead to an instantaneous loss of oil pressure, causing the engine to seize or stall at highway speeds. This creates an immediate risk of: Loss of power steering and braking assist in traffic. Potential rear-wheel lockup (in RWD/Manual configurations) leading to loss of vehicle control. Catastrophic engine failure in the middle of active traffic, requiring an emergency maneuver. Has the problem been reproduced or confirmed by a dealer or independent service center? Assessment: The existence of the defect is confirmed by BMW’s internal technical case PuMA Measure 65494813. Furthermore, the manufacturer released a software update (S18A-21-03-567) specifically to reduce oil pressure during cold starts to mitigate stress on this plastic component—a "band-aid" fix that acknowledges the hardware's fragility. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Assessment: Not yet, as the vehicle is being operated under the assumption of a known safety defect. However, independent mechanics and BMW master technicians across the industry have verified that early B58TU builds (2018–2020) almost universally contain the defective plastic-internals pump.

Emergency call system - TCB module failure. A Telematics Control Box, is an embedded computer in my X3. It processes, and transmits data wirelessly. it is a hub for my car to connect services like GPS tracking, diagnostics, infotainment, emergency calls (e.g., eCall), and vehicle-to-everything (V2X) communication, enabling real-time monitoring for safety, efficiency, and fleet management. It connects the car to the internet for emergency services. If the TCB were working properly it would call 911 automatically. It has failed and now it will not call automatically if I get into an accident. The car had less than 50K miles and the dealer wanted to charge $2500 to fix. This should be a recall due to the safety issue. This isn't just a minor inconvenience; it's a critical safety feature failure, disabling automatic crash notification and location services. It has disabled all other msg and the error msg stays on continuously and I am unable to see any other msg that could appear.

Appears to be related to recall 25V636. Vehicle is 2020 BMW X3 M40i, equipped with same engine as the Supra (B58). Engine would not start with the push of the "start button". Pressing a second time would sometimes start, but as time went on the number of presses required to start took minutes to up to 30 minutes before engine would start. Had starter motor replaced October, 2025 and mechanic observed that starter motor was shorting out, similar to existing recall. However, my vehicle is not included in the recall.
