2020 BMW X3

It has come to my attention that liquid from the Positive Crankcase Ventilation (PCV) system may leak onto the water pump electrical connector. This condition can lead to an electrical short circuit and, in rare cases, may increase the risk of a vehicle fire. This issue presents a serious safety concern for vehicle owners and others on the road. A failure of this nature, especially one that carries a fire risk, warrants immediate review and corrective action. I respectfully request that NHTSA investigate this matter and determine whether a safety recall is necessary to address this defect. The dealership noticed the leak beginning at the weep hole of the waterpump. No incident occurred this is for preventive measures and review for recall and reimbursement

The heated seat element had a runway incident that caused the seat to smoke and burn a hole through multiple layers and ultimately damaging the airbag sensor mat disabling the passenger airbag system

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. They are aware.

The contact owns a 2020 BMW X3. The contact stated that while her son was using the rear passenger's side seat belt, the contact became aware that the seat belt was fraying. The vehicle was taken to the dealer and was provided an estimate for the seat belt replacement. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 49,000.

I am submitting a formal safety complaint regarding a defect in my 2020 BMW X3 that has resulted in the failure of a critical emergency safety system. The vehicle displayed an error message indicating an “Emergency Call System Malfunction.” I brought the vehicle to BMW of Murrieta on March 30, 2026, for diagnosis and repair. Upon inspection, the service center determined that the Telematic Control Unit (TCU) had sustained water damage. This damage was attributed to water intrusion originating from the vehicle’s shark fin antenna. This is a known issue documented by BMW in internal Service Information Bulletin SIB 65 12 22 (dated October 5, 2022). Despite acknowledgment of this known defect, BMW declined to cover the repair costs for both the antenna-related water intrusion and the resulting damage to the TCU. This failure presents a significant safety hazard. The emergency call system is designed to automatically notify emergency services in the event of a collision. With this system inoperable, occupants may be unable to receive timely emergency assistance, increasing the risk of serious injury or death. Given that BMW is aware of this defect and its potential to disable a critical safety feature, I believe this issue warrants further investigation and should be considered for a mandatory safety recall.

Due to a TSB (SIB 65 12 22) wherein the roof antennae leaks water and causes a short in the telemetry module, the car does not have pedestrian warning, navigation or backup camera / cross traffic warning. The car is drivable, but compromised from a safety perspective.

We had an oil pump failure that was because the part was plastic, not metal.

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.

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.

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.

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.

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

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.
