1. What component or system failed or malfunctioned, and is it available for inspection upon request? The suspected failed component is the front differential carrier bearing on my 2021 BMW 750i xDrive. [XXX] BMW of Westmont, Illinois diagnosed carrier bearing damage and oil leaks and recommended replacement of the front differential. The vehicle has approximately 53,791 miles. The failed differential/carrier-bearing assembly is currently available for inspection, subject to the vehicle remaining at the dealership and before the component is replaced or discarded. I have specifically requested that BMW and the dealership retain the failed component if inspection or engineering analysis is necessary. The dealership's repair order is XXX, dated XXX. 2. How was your safety or the safety of others put at risk? The vehicle developed a significant grinding noise during acceleration from a stop. The grinding continues for approximately 5–15 seconds, depending on how long the vehicle is under acceleration, and goes away after the vehicle reaches approximately 30–40 MPH. I am concerned that failure of a major front drivetrain component could result in an unexpected loss or interruption of proper power transfer, particularly during acceleration from a stop or at low speeds. The vehicle also has a documented differential oil leak progressing to a drip. I am concerned that continued loss of differential lubricant could contribute to further mechanical damage or failure. I have therefore limited use of the vehicle while seeking diagnosis and determining the appropriate repair. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The vehicle was inspected by Laurel BMW of Westmont, Illinois, an authorized BMW service center. The dealer documented the customer's complaint as a grinding noise when accelerating from a stop and documented the diagnosis: “Front differential replacement due to carrier bearing ,oil leaks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Took my 2020 BMW 7 Series into BMW San Diego because there was fluid leaking. Upon diagnosis at the dealership, I was notified I needed to replace the front differential as it was coming apart. The leaking fluid was identified as differential fluid. The vehicle has 54,308 miles on it. My research indicates front differentials should not need replacement until nearly 150,000 miles. A broken front differential is considered to be very bad and makes a car unsafe to drive as it causes severe handling issues, loss of control and potential damage to the transmission. A broken differential can cause the vehicle to lock up or lose steering control. Me and my family have been at risk as it is unclear how long this issue has been happening. The problem has been confirmed by BMW San Diego. The cost to replace was quoted as about $10,251. There are no warning lamps, and there are no messages indicating there is a problem with the vehicle. Not sure when the issue started. Apparently, due to my research I’ve learning many 2020 BMW’s seem to need to have the front differential replaced with mileage between 38,000 and 55,000.

STEERING, WHEELS, ELECTRICAL SYSTEM
On [XXX], while driving on a busy boulevard in Wilmington, Delaware, my 2020 BMW 750i suddenly lost all power (engine and electrical) without any warning. The vehicle completely shut down in traffic, creating an extremely dangerous situation. There were no warning lights or messages before the failure. I called BMW Roadside Assistance for help but was informed that because my warranty had just expired, they canceled the tow truck that was already en route and turned it away. This left me stranded in a live traffic lane until I could arrange my own tow service from Geico. I called Wilmington Police for assistance and eventually had to run a couple of blocks to flag down a police vehicle that arrived and dropped several flares behind my vehicle. The vehicle was later inspected at Union Park BMW (Wilmington, DE), where the technician stated that the failure was due to a defective cell in the main battery. This experience has made me very nervous to drive the car again, as a total loss of power without warning could lead to a collision or injury. I believe this represents a serious safety defect in the vehicle’s electrical or battery system and should be investigated.

Service Bulletin SI B11 09 17 Same issue with my car, 2017 BMW 750i xDrive. Drivetrain malfunction issues identical to SB noted. My car has a manufactured date 07/2016, one month after SB dates covered, yet same part numbers are used in this month as well. Not fair that other vehicle owners with same part numbers get this covered, as I have to pay over $3k for repair, to then wait IF a SB gets releases, then have to chase BMW file a RP claim. Wastegate issues across all G11 models!

SEAT BELTS
Last month, my 2016 BMW 750i XDrive displayed a warning message on the dashboard: “Extended action required. Active Protection restricted. You can continue driving. Roadside Assistance not required. Pre-tensioning of seatbelts not possible. If the problem recurs, have it checked by your service center.” When I took the vehicle to my local dealership, BMW of Gwinnett Place, the service advisor mentioned he had never seen this warning before. After diagnosing the vehicle, he informed me that the warning was related to the passenger seatbelt. He quoted me $1934.93 for parts and labor to replace the seatbelt. When I inquired about any recalls for this issue, he said there were none and that I would have to pay out of pocket. I expressed my concern that this is a major safety issue and that my family’s lives are in danger if they are sitting in the passenger seat. He reiterated that there was nothing more he could do. I contacted BMW to report the issue and seek a remedy. The representative stated that since my vehicle is out of warranty, the responsibility is mine. I strongly believe BMW should issue a recall for this issue and take full responsibility to resolve and fix the seatbelt problem on this vehicle. This is a significant safety concern, and consumers’ lives are at great risk due to this seatbelt problem on my 2016 BMW 750i.

SERVICE BRAKES, SUSPENSION, WHEELS
The chasis function is limited on this vehicle due to failed right rear air suspension. Leaking right rear strut, and failed air compressor. Additionally, as a result my car needs an alignment. There was a service bulletin in regards to this exact issue in which BMW offered an extended warranty to repair vehicles free of charge up to 8 years/80,000 miles (MC-10215743-9999.pdf) My vehicle is currently at 92,000 miles but within 8 years. I never received the notification. If I would have I could of had the vehicle inspected and fixed within the extended warranty time frame. I'm being told that BMW will not cover the cost because my vehicle is outside of the timeframe they agreed upon in the settlement. The cost is $ 8600.00. This incident is the second issue I've faced. I purchased the vehicle certified from a BMW dealership. The initial problem I faced was with a failing braking system that was fixed through warranty after multiple trips to the dealership. I was at risk of the vehicle not stopping which could have resulted in a terrible accident. Now with this second issue I'm again at risk for my safety. BMW should be held accountable for producing vehicles with such safety concerns and at minimum be responsible for the cost to repair these issues.

There are two grill shutter actuators. One for the upper and one for the lower. Different part numbers. NHTSA issued a TSB for N63R in 2019: MC-10160279-9999 (G12 (N63R)/G30 (B58M) RADIATOR GRILL UPPER AND LOWER ACTIVE AIR FLAPS: LIMITED WARRANTY EXTENSION TO 10 YEARS/120,000 MILES). My vehicle is a N62R and there are hundreds perhaps thousands of reports of the IDENTICAL part numbers from BROSE Manufacturing (USA / Germany) failing. For example, my upper failed in APR 2023 after a repair I paid for in SEP 2022 with a P/N manufactured in 2021. Then, the lower actuator failed which has a manufacture date of 2017 (so it is the OEM part). Though the upper actuator is coded to remain open on fault, the lower is for some reason coded to remain closed on fault. If the fault codes are incorrectly interpreted by the [XXX] when the vehicle is in operation, then the engine could quickly overheat and lead to major issues for the occupants, but likely result in thousands of dollars of engine repairs. I urge you to reconsider the TSB and issue a recall/warranty extension for all BMW G11/12/30 and similar (in fact, this part is used on all series with upper and lower shutters: 5, 7 and X from 2015.) The main problem I am having is that there ARE NO PARTS IN STOCK at BMW worldwide. [XXX] has not responded. Thank you. “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”
