2020 BMW X7

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.

The contact owns a 2020 BMW X7. The contact received notification of NHTSA Campaign Number: 25V644000 (Electrical System). The contact stated that while driving at an undisclosed speed and making a left turn, the vehicle stalled in the middle of traffic. The contact immediately depressed the brake and attempted to shift into park(P), but the transmission failed to respond as needed. The contact remained in the vehicle with the brake pedal depressed until Roadside Assistance arrived. The contact stated that the Roadside Assistance team held the start button down and the gear selector was shifted into neutral(N) for a second and continued to inadvertently shift back to park(P). The vehicle was towed to an independent mechanic who was unable to properly diagnose the vehicle and referred the contact to the dealer. The vehicle was then towed to the dealer, where it was diagnosed and determined that the starter needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 85,600.

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.

Hello , I would like to report a failed front differential on my vehicle. This issue was diagnosed by an independent BMW shop and is currently being repaired. Mine made it to 69k miles but many others have had theirs failed before 50k miles. My main goal is to bring light to this issue since it seems to be a design flaw. There's also numerous reports for failed transfer cases since they aren't normally serviced by BMW dealers. I've attached both repair invoices.

My front differential has failed and my vehicle has 62,000 miles. There is no recommended service and maintenance schedule for replacing fluids for the front differential so I thinking that this failure is due to an engineering design flaw including no recommended schedule to service the unit. It also seems this component may be too small/weak for the engine output. I has seem this failure reported on many blobs and users groups and seems to be recurring issue that BMW turns a blind side to. They ask why an extended warranty was not purchased and seeing that this is a recurring problem I am asking for a possible recall to force BMW to pay or reimburse others for repairs.

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.

• Third-row seat in my 2020 BMW X7 failed during normal operation and trapped my [XXX] daughter between the seatbacks. • She sustained injuries to her legs (documented in photos). I injured my arm while trying to free her. • Approximately 10 people witnessed the incident. • Seat would not move or release electronically or manually—no functional emergency release. • Multiple BMW system warnings occurred before the incident, including:  – “Third row seat risk of injury”  – “Right/left rear seat unlocked”  – “Right/left rear seat back unlocked” • BMW’s inspection found the passenger-side third-row seat motor housing broken. • There was no misuse and the failure occurred during normal operation • BMW refuses to repair the defect under warranty and attempted to return the vehicle unrepaired. • BMW suggested an “outside influence,” but evidence does not support this. • This defect creates a serious entrapment and injury hazard with no reliable manual release. • Requesting NHTSA investigation into BMW X7 third-row seat motors, locking mechanisms, and lack of emergency release due to risk of occupant injury or inability to evacuate a trapped passenger. There is an open and unresolved case with the manufacturer. Please help us and others that may be in danger. We still don’t have our vehicle back after 6 weeks and they state they will not fix it and return it to us broken, unsafe, and not usable.

I am filing this complaint because the third-row passenger seat in my 2020 BMW X7 has a serious defect that poses an immediate safety risk to children and passengers. The third-row seat malfunctioned while my child was exiting the vehicle. The powered seat began moving unexpectedly and trapped my child’s leg, and we had extreme difficulty getting the seat to release. This is an extremely dangerous failure for any powered seat, especially one that is frequently used by children. This is not normal wear and tear — this is a mechanical and electrical failure of a safety-critical seat system. BMW Fresno has had the vehicle for more than six weeks and cannot fix the problem. BMW North America reviewed the case but denied responsibility and closed it, even though the defect affects a powered safety-critical seat. We still have no repair, no explanation, and no assurance that the seat is safe. I am filing this because the powered seat poses a clear risk of injury, and BMW has not resolved or acknowledged the safety defect. I request that NHTSA investigate the 2020 BMW X7 third-row seat system for potential entrapment hazards. Actions Taken •BMW Fresno inspected the vehicle and kept it for 6+ weeks. •BMW NA conducted a review but has refused to cover cost of repair or acknowledge a defect. •I am seeking NHTSA’s involvement because this is a clear safety problem that BMW has not corrected.

Transfer case broke and struck the engine while driving.

X7 models from year 2020 -2022 have a particular issue at stake which is a manufacture default as it's been reported in many cases in X7 models. I'd like have this Transportation safety to please look into this issue a safety recall as there is a shuddering issue in most x7's when turning right or left at a lower speed which slips the vehicle. I would appreciate it if someone could look into this. Thanks,

I am submitting this complaint based on recurring drivetrain and structural failures in my 2020 BMW X7 (VIN: [XXX] ), which raise serious concerns about reliability and safety. Most recently, the vehicle exhibited shuddering, power loss, and a “neutral-like” disengagement at low speeds. BMW of Pembroke Pines confirmed this through a test drive. However, instead of mechanical replacement, the dealer performed a VTG oil flush and attempted a calibration, which—according to their own documentation—“lost connection.” These signs point to recurring issues with the ATC (transfer case), a known point of failure in several BMW X models. Additional manufacturer defects I’ve experienced include: - Two incidents of cabin water intrusion from separate leaks - A dashboard panel burst shortly after purchase - Rear seat failure requiring a $7,000+ repair BMW North America refuses to provide further assistance despite acknowledging the repair history. This leaves me with a potentially unsafe vehicle, prone to recurring drivetrain failure without a clearly defined remedy. I respectfully request that NHTSA investigate whether the Active Transfer Case and related VTG components in the BMW X7 pose a defect trend requiring formal attention.

While my wife was driving our 2020 BMW X7M under normal conditions, the vehicle experienced a catastrophic drivetrain and differential failure. According to the BMW dealership’s service manager, internal drivetrain components became disconnected while the vehicle was in motion. This caused parts to spin freely and damage surrounding systems. Fortunately, no crash occurred, but the technician emphasized that it could have easily led to an accident. There was no external impact, accident, or driver error. Both the BMW dealership and an independent insurance adjuster from GEICO confirmed the failure appeared to be mechanical and internal in nature, possibly due to a manufacturing defect. This failure poses a significant safety risk to occupants and other drivers. Had it occurred at higher speeds or in traffic, the consequences could have been severe. I believe this incident warrants investigation due to potential systemic safety concerns. I am requesting that NHTSA review this failure for manufacturer defects and evaluate whether similar complaints exist regarding drivetrain integrity in BMW X7M models. Supporting documentation, including video evidence, dealership notes, and the insurance report, are available via this link [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 BMW X7. The contact stated that while attempting to start the vehicle, the engine failed to turn over. The message "Starter Motor Overheating" was displayed; however, there was no warning light illuminated. The vehicle was towed to a local dealer where it was diagnosed, and the contact was advised that the starter motor and battery were faulty and needed to be replaced. The contact was also advised that the coolant needed to be drained and refilled. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 24V576000 (ELECTRICAL SYSTEM, ENGINE AND ENGINE COOLING); as a possible cause for the failure. The manufacturer was notified of the failure. The approximate failure mileage was 58,000.

The contact owns a 2020 BMW X7. The contact stated that while driving at an undisclosed speed, there was an abnormal sound coming from the wheels while turning to the right or the left. No warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that both front control arms needed to be replaced; however, the vehicle was not repaired due to the cost. Upon investigation, the contact related the failure to NHTSA Campaign Number: 20V678000 (SUSPENSION); however, the VIN was not included. The vehicle was previously serviced under NHTSA Campaign Number: 25V644000 (ELECTRICAL SYSTEM). The manufacturer was not made aware of the failure. The failure mileage was approximately 42,000.

Without warning the vehicle came to an abrupt stop while going about 25 mph. I got out and checked and noticed a liquid dripping from underneath the front area of the vehicle. Later determined it was the front transfer case. I really would hate to think what could have happened at higher speeds. Again, no warning at all.

Transfer case causes vehicle to shake when driving straight or turning from a complete stop or low speeds.

I was driving and as I parked on my driveway a message popped up on my dash board saying " " Increased Steering efforts" then I wasn't able to move the steering wheel at all, it feel like it got locked.
