Owner report 11594608 · 2024-06-16 (June 16, 2024)
The transfer case became damaged causing shuddering and loss of power while turning and accelerating. Once failed all power lost to rear wheels. My vehicle is available for inspection upon request and the problem has been confirmed by BMW dealership and replacement is required. Any loss of control of your vehicle is a safety hazard. This is a widely known issue and a recall has already been issued for years 2013-2016. The problem still exist in later models mine being a 2021.

Owner report 11695868 · 2025-10-27 (October 27, 2025)
The transfer case in my BMW X7 began making grinding, jerking, shuttering around 65,000 miles. The dealer failed to diagnose the issue at that time when I brought it in at 71,000. (approximately $9,000–$10,000). Transfer cases "should be" designed to last well over 150,000miles. Maybe my car was a lemon but it seems to be a common theme/legal suite for BMW X7 owner.s This issue connitued causes sudden loss of power delivery, shuddering, and unpredictable handling, especially during acceleration or turning, which can increase the risk of an ac…

Owner report 11465047 · 2022-05-17 (May 17, 2022)
When moisture gets into the cupholders of a BMW 2021 X7, it leaks into the electrical system for the airbag sensors and seatbelt sensors. This makes them USELESS in an accident. BMW currently has a lawsuit pending against this VERY ISSUE. A small amount of soda spilled in the cupholders by my daughter. It was quickly cleaned and dried- but this caused a leak and lead to the restraint system failure- which renders my airbags in the driver and passenger seats useless- along with the seatbelts. They will NOT work in the event of an accident. This …

Owner report 11638117 · 2025-01-23 (January 23, 2025)
The water pump pulley "exploded", causing the accessory belt to fall off which drives the alternator. The pulley "shrapnel" was thrown into the cooling system and damaging the hoses causing immediate loss of coolant. The loss of electrical power due to the alternator being inoperable and the loss of cooling could have caused the vehicle to malfunction in a dangerous manner. Fortunately, the vehicle displayed an error message and was towed to the dealer without further incident.

Owner report 11472663 · 2022-07-07 (July 7, 2022)
When applying brakes and releasing the brakes there is a grinding sound. The grinding sound is pronounced when applying the brake and turning the steering wheel at the same time. When I took the vehicle to Checkered flag BMW of Virginia Beach, I was told per BMW engineering it was norm operating characteristic. The Shop Foreman said he had several customers complain about the same problem and duplicated the problem while driving my vehicle. He was the person that showed me the noise was much louder when turning the steering while braking. The r…

Owner report 11496690 · 2022-12-09 (December 9, 2022)
When starting the vehicle and shifting into drive, "hard" brakes are felt. Brake pedal is "stuck" in a high position and cannot be compressed. The vehicle is extremely unstable - the car lurches forward when brakes are slightly released. Excessive brake pressure is required to prevent the vehicle from moving inadvertently. This persists for 10-60 seconds, then the brakes relax into the normal position and no other issues are experienced. Confirmed NO lights on dash or warnings sounded. This has been experienced 4 times in 6 months. Issue has be…

Owner report 11541234 · 2023-08-28 (August 28, 2023)
While merging onto the highway the car violently jerked itself into the left lane without warning, nearly causing me to collide with another car. Error messages about "driver assistance" appeared. All screens then went black and the car rebooted. It pulled away from the direction I was driving several more times on my way home, but less severely. 3 weeks earlier multiple systems failed and power steering went out. That time the car was pulling me in the opposite direction I was steering. Was told it was a software issue that was fixed. Then th…

Owner report 11629982 · 2024-12-10 (December 10, 2024)
On Sunday, December 1, 2024, the high-pressure fuel pump failed while driving in a roundabout next to a freeway, causing the car to stop and the gearbox set itself to PARK. Bellevue BMW has ordered a new fuel pump ?control board? If there were any warning lamps or messages, they did not appear before the complete failure of the fuel pump. The BIG problem was that we were not able to shift into NEUTRAL so the car could be pushed safely to the side of the road. The tow truck operator had to put rolling skids on the tires in order to load it o…

Owner report 11576771 · 2024-03-12 (March 12, 2024)
The car’s fuel capacity and miles remaining projection after refueling, both indicate a 12 gallon capacity fuel tank, despite Toyota’s published 17.2 capacity fuel tank. Well documented online, the safety concern here is 1) the fuel level sensor is defective, 2) the gas tank neck design is defective, 3) the miles remaining calculator is calculating incorrectly creating stranded passenger risk, or 4) misleading marketing though not a safety issue, but would have deterred me from purchasing the car due poor distance range. If true, I would want T…
