2020 BMW X3 Complaints

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 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. A recall should happen

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.

The contact owns a 2020 BMW X3. The contact stated that several attempts were needed while cold-starting the vehicle. The contact stated that prior to receiving notification of NHTSA Campaign Number: 25V636000 (Electrical System); the battery was replaced; however, the vehicle was still difficult to start. The local dealer was contacted, and the contact was informed that the remedy was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not informed of the failure. The failure mileage was approximately 51,000.

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.

There is an open recall(NHTSA Recall Number25V636) for my vehicle since September 2025 and there is still no remedy available from the manufacturer (BMW). I am told by the dealer that they won't have the part for next several months. This is unacceptable as I need to get the urgent safety recall fixed as soon as possible.

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 lower radiator blinds/air flaps are not working. I have a check engine light on and the dealership is stating that is what is wrong. This is a known issue with BMW vehicles and has been a recall with other BMW models.
