Low oil sensor continues to light up and says i am low on oil. Found out that my oil pump was the main cause of the issue. At this time I have to have the oil pump replaced. It was also determined there have been numerous reports regarding oil pump failure in the 2020 BMW x7 due to an internal plastic part.

While driving the vehicle sensor lights began to come on. I assumed it was a dirty outside sensor. Not long after the ABS system lit up and my car said traction even though I was just pulling into my driveway. I quickly turned around and drove to my mechanic. Showed him all the lights and he connected the computer to read the error codes. Found out that my oil pump was the main cause of the issue. Double checked to make sure it wasn't a battery failure causing incorrect error codes and the battery was in good condition. At this time I have to have the oil pump replaced. It was also determined there have been numerous reports regarding oil pump failure in the 2020 BMW x7 due to an internal plastic part.

I am writing to formally report a potential safety-related defect involving BMW vehicles equipped with the B58TU engine, primarily affecting model years 2019 through 2021. My vehicle experienced a sudden loss of engine oil pressure that resulted in catastrophic engine failure. This condition occurred with little to no warning and led to immediate vehicle disablement. The failure created a hazardous situation, as the vehicle was no longer able to maintain propulsion and could have placed occupants at risk because it occurred in active traffic or unsafe conditions. Based on my experience and additional research, the issue appears to originate from the engine’s oil pump design. Specifically, the oil pump contains an internal pressure-regulating component originally manufactured from plastic. This component is prone to fracturing, particularly during cold starts or low ambient temperatures. When this failure occurs, oil pressure becomes erratic or is lost entirely, often without sufficient warning to prevent engine damage or vehicle shutdown. My vehicle had this occur on January 20th 2026, as it was 5 Degrees outside. I suddenly lost oil pressure and had my vehicle’s engine catastrophically fail on a highway with my two small children ages (3) and (7 months) in the vehicle. In some cases, drivers may observe warning signs such as inability to measure oil level electronically, abnormal oil pressure readings, or drivetrain malfunction warnings. However, these indicators are inconsistent and often appear only moments before complete failure, leaving insufficient time for corrective action. This issue represents a significant safety concern for the following reasons: * Sudden loss of oil pressure can result in immediate engine shutdown or loss of propulsion while driving * Failures frequently occur under predictable conditions (cold starts in low temperatures), indicating a repeatable defect * Drivers are not provided with adequate warning to safely respond before damage.

I'm reporting a safety issue with BMW vehicles equipped with the B58TU engine, primarily 2019-2021 models. These vehicles have an oil pump with an internal plastic component that regulates oil pressure, and this part is fracturing in the field, causing sudden loss of oil pressure. The failure typically occurs during cold starts in low temperatures. When it 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, or sudden drivetrain malfunction warnings. These can rapidly progress to engine shutdown or severe damage from oil starvation. This creates a dangerous situation because the vehicle can become disabled without warning while driving or after startup. This is especially hazardous when cars become immobilized in traffic or during winter conditions when failures occur most frequently, leaving occupants exposed to freezing temperatures while awaiting assistance. Pump replacement requires extensive disassembly and commonly costs $6,000-$8,000, assuming no engine damage. A critical concern: owners cannot determine if their vehicle has the original plastic pump or the later metal revision. BMW's VIN-based parts lookup now shows updated components even when original plastic parts remain installed, and BMW has removed the original plastic part number from dealer networks entirely. Failures are reported across multiple production years, and the scope of affected vehicles remains unclear. Because this condition causes sudden vehicle disablement without adequate warning, especially in cold weather, I believe this warrants investigation as a potential safety-related defect.

Oil pum with plastic internals. Repeat hot and cold cycles cause premature failure of the plastic components and cause loss of oil pressure along with the pump grenading itself.

My vehicle is included in BMW Recall Campaign No. 25V 644 – Engine Starter. It has repeatedly failed to start, and on two separate occasions the engine completely stalled while I was stopped at a traffic light. Each time, it took multiple attempts before the car would restart. I have also been stranded in numerous parking lots—during both extreme heat and freezing temperatures—with my children because the vehicle would not start. These incidents were unexpected, unsafe, and entirely consistent with the symptoms described in the recall. We have experienced these problems since purchasing the vehicle, but at the time we had no reason to believe we needed to document every occurrence. Now that BMW has acknowledged a fire risk defect and still has no available remedy, I do not feel safe continuing to operate this car. BMW has even advised owners not to park in a garage due to the potential fire hazard. The first recall was issued in 2024 and did not resolve the issue. The subsequent recall in August 2025 still has no fix. This ongoing situation presents a serious safety risk, and it is unacceptable that it remains unresolved. BMW should be buying these vehicles back and compensating owners for the significant inconvenience and danger this defect has caused.

The check engine light on my 2020 BMW X7 intermittently illuminates and then clears without warning. A BMW technician diagnosed the cause as a malfunctioning active grille shutter assembly at the front of the vehicle. Research shows this is a widespread issue among BMW X5 and X7 models of similar years, with many owners reporting the same failure and expensive repairs. This appears to be a systemic defect, not an isolated incident. Because the grille shutter directly affects engine airflow and cooling, this issue raises reliability and potential safety concerns and should be reviewed for a possible recall.

The contact works for a company that owns a 2020 BMW X7. The contact stated that while his boss was driving at an undisclosed speed, the vehicle stalled. The driver was able to veer to the side of the road. The vehicle was towed to a station. The vehicle was then towed to the dealer, where it was diagnosed and determined that the front trans-axle had disintegrated, causing the shaft to pinch and to create an 8-inch hole at the bottom of the oil pan. The contact stated that a significant amount of oil had leaked from the vehicle. The dealer determined that the transmission and engine had failed and needed to be replaced. The dealer informed the contact that it was a known failure, but the vehicle failure was the most dangerous reported failure. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that no assistance could be provided because the VIN was not included in a related recall. The failure mileage was approximately 140,218.

The contact owns 2020 BMW X7. The contact stated while driving 30 MPH, the message "Oil Pump Leak Over - Get the Vehicle Towed to Local Service Dealer" was displayed. The vehicle was towed to an independent mechanic, who could not repair the vehicle. The vehicle was towed to the dealer, where an unknown diagnosis was made. The vehicle was then towed to Baltimore Motor Works, where it was diagnosed that the engine oil pump had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure, but no assistance was provided. The contact was referred to the federal safety agency Hotline to report the failure. The failure mileage was 60,000.
