2019 BMW X7

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/lubrication. 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, demonstrating knowledge of the defective component.

I was told today that my BMW engine oil pump is failing because of plastic internal components which will cause irreversible catastrophic engine damage during operation which is extremely dangerous and that I was informed by the dealer that BMW quietly changed them 2 years after due to the failure rate. If the oil pump shatters, debris can permanently damage the engine during operation jeopardizing my safety and those driving around me, making replacement with the upgraded, all-metal oil pump, that BMW quietly changed due to this failure, nearly $6k -$8k to fix and is not covered though they admit it is a known failure/safety issue. As of XXX, BMW Korea is running a free repair campaign (recall) to address oil pump failures affecting the B58TU engine in that country. Affected vehicles include models manufactured between XXX and XXX. BMW Korea replaces the non-safe original plastic oil pump with BMW's upgraded metal design, and even covers prior out-of-pocket replacements. NHTSA needs to hold BMW accountable and force BMW USA to complete the same safety recall for the exact same issue of faulty engine oil pumps they installed to save money as BMW Korea for the United States. Safety recalls should NOT be optional in USA and especially so if BMW is already doing the recall in another country for same issue identified in their cars sold here in the [XXX] too.

The shark fin antenna seal on my BMW failed, allowing water to enter the Telematics Control Unit (TCU). This caused a complete failure of the vehicle’s Emergency SOS / BMW Assist crash notification system. The failure occurred without any warning messages or prior indications that the system was compromised. Because the TCU controls the vehicle’s automatic crash notification and emergency call functions, this failure disabled a critical safety system. This defect placed me and my family at risk, as the vehicle would not be able to automatically contact emergency services in the event of a collision or other serious incident. The failure first occurred in April 2026. I immediately contacted my BMW dealership’s service center, where the service advisor acknowledged that the shark fin seal had issues causing this to happen (water intrusion). However, instead of treating this as a safety defect, I was told to file an insurance claim. I also contacted BMW Customer Service, but both the dealership and BMW declined responsibility and refused to cover the repair. The shark fin antenna seal is a manufacturer‑installed, non‑serviceable component. Its failure directly disabled a federally regulated safety system without warning. BMW’s refusal to address this issue leaves the safety defect unresolved and exposes other owners to the same risk.

The contact owns a 2019 BMW X7. The contact stated that while driving at an undisclosed speed, the engine overheated and the engine seized. The check engine warning light was illuminated. While attempting to restart the vehicle, the vehicle restarted with the power train warning light illuminated. The vehicle was taken to the dealer; however, the vehicle was not diagnosed, and the failure reoccurred. The failure was a persistent failure. The contact stated that there was thick white smoke coming from the exhaust. The contact noticed a fuel odor on the interior and exterior of the vehicle. In addition, the RPM was elevated. The vehicle was towed to the dealer. The contact stated that the failure was a known failure with the vehicle. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the repair was not covered under recall or warranty. The failure mileage was approximately 102,000.

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 use a variable-displacement oil pump with an internal thermoplastic component that regulates oil pressure. This component is increasingly failing in the field, often fracturing and causing sudden loss or instability of oil pressure. Failures commonly occur during cold starts in low temperatures. When the component breaks, oil pressure may become erratic or drop entirely, often with little or no warning before engine damage or vehicle shutdown. Early warning signs can include inability to measure oil level, abnormal oil pressure behavior, or drivetrain malfunction alerts. In many cases, failures quickly lead to engine shutdown or severe damage due to oil starvation. This can leave vehicles suddenly disabled while driving or shortly after startup, creating a safety risk—especially in traffic or in cold weather, where occupants may be exposed to freezing conditions while waiting for assistance. Repair requires extensive disassembly, with oil pump replacement alone typically costing $6,000–$8,000, excluding additional engine damage. Owners also cannot reliably determine whether their vehicle has the original thermoplastic component or an updated metal version, as parts databases now default to the revised design regardless of what is actually installed. Failures have been reported across multiple model years, and the full scope of affected vehicles remains unclear. Because this issue can cause sudden vehicle disablement without adequate warning—particularly in cold conditions—it may represent a safety-related defect warranting investigation.

BMW has a known issue that the fin antenna on the roof leaks and sets off a cascade of dangerous issues with the Emergency Call function and disabling the heads up dash so that you cannot see your navigation. On April 2, 2026 in Austin, TX it rained and our car started sending an Emergency Call request repeatedly to BMW. BMW operators called repeatedly even though they knew there was no emergency and that they were actively interrupting our driving. The heads up dash would not allow us to see our maps to navigate, but only displayed a notification that an Emergency Call had been initiated. BMW needs to address and recall this antenna seal so that owners can use their cars safely (with all functions) while not paying out of pocket for BMW's failure.

Safety Defect Report — Engine Oil Pump Failure (BMW B58TU Engine) Component or System Involved The failure involves the variable-displacement engine oil pump installed in BMW vehicles equipped with the B58 Technical Update (B58TU) engine, commonly found in model years 2019–2021. The oil pump contains an internal thermoplastic adjusting component that regulates engine oil pressure. Field reports indicate this internal component can fracture, causing unstable or complete loss of engine oil pressure. The failed component may be available for inspection upon request if retained after repair. Description of Failure and Safety Risk When the internal thermoplastic adjusting component fails, engine oil pressure regulation becomes erratic or is lost entirely. This results in insufficient engine lubrication and may cause sudden engine shutdown or severe mechanical damage due to oil starvation. Loss of engine power or complete engine disablement can occur without adequate warning, creating a safety hazard if the vehicle becomes immobilized while driving or shortly after startup. This risk is heightened when the failure occurs in active traffic or in cold weather conditions, where occupants may be exposed to freezing temperatures while awaiting assistance. Operating Conditions and Failure Pattern The failure most frequently occurs during cold-start operation in low ambient temperatures. Failures appear to progress rapidly once symptoms begin. Warning Lamps, Messages, or Prior Symptoms Reported precursor symptoms may include: Inability to electronically measure engine oil level. Abnormal or unstable oil pressure behavior. Sudden drivetrain malfunction warnings. Minimal or no actionable warning prior to engine damage or shutdown. These symptoms may appear shortly before failure or may not provide sufficient time for corrective action. Inspection or Confirmation of the Problem Field failures have been reported across multiple vehicles and production years. In many cases
