On August 19, 2026, my 2022 BMW X7 xDrive40i experienced multiple safety\-related warnings at approximately 50,411–50,427 miles\. The vehicle first displayed “Increased steering effort” and instructed me to drive carefully to a service center\. It then displayed a red power\-supply warning stating: “Stop carefully\. Do not continue driving\. Continued driving will lead to malfunction of safety relevant functions\. Battery cannot be recharged\. Call Roadside Assistance\.” A drivetrain warning subsequently appeared\. After the vehicle was stopped and later restarted, the warnings temporarily cleared\. BMW of Atlantic City performed a KeyReader scan\. The report documented the steering, power\-supply and drivetrain messages and showed fault code 80402F, described as “12 VOLT VEHICLE BATTERY TOTAL DISCHARGE\.” The report showed the battery status as “OK” when it was read\. BMW Service Information Bulletin 61 01 23 discusses fault 80402F on certain G07 X7 vehicles and states that a software error may prevent the vehicle from entering sleep mode, resulting in discharge of the 12\-volt battery\. The precise cause in my vehicle has not yet been conclusively diagnosed\. I am concerned that an electrical or software failure can occur while the vehicle is operating and trigger reduced steering assistance, drivetrain warnings and the announced potential malfunction of other safety\-relevant systems\. There was no collision, fire or injury in this incident\. I am requesting that NHTSA review this issue for a potential safety\-defect pattern in similarly equipped BMW X7 vehicles\.

Component Failing: Telematics Control Unit (TCU) / SOS Emergency Call System This vehicle is experiencing an intermittent, total failure of the factory-installed SOS/Emergency Call System due to a known manufacturing defect. BMW has documented this issue in Technical Service Bulletin SIB 65 12 22, admitting that an improper factory paint and sealing process causes the roof-mounted shark fin antenna to separate from the vehicle body. As a direct result of this assembly defect, rainwater has leaked past the roofline and into the vehicle's interior cabin, flooding and short-circuiting the Telematics Control Unit (TCU). Consequently, the critical life-safety SOS system is failing to operate correctly. In the event of a severe crash or medical emergency, the vehicle's automated collision notification system will fail to contact first responders or transmit the vehicle’s GPS location. The manufacturer has acknowledged the defect to me but refuses to cover the repair outside of the narrow 50,000-mile warranty window, nor have they expanded their regional California legal settlements to protect drivers nationwide. Because this factory defect directly compromises a critical federal safety communications component, I request that the NHTSA open an official investigation into BMW model years 2017–2023 to mandate a nationwide safety recall.

The front passenger side door is unable to open from inside or outside the vehicle. The door actuator failed, and this has been confirmed by the dealer. This is an obvious safety issue as it prevents egress in an emergency. According to Internet forums, this seems to be a known issue across BMW platforms.

Transfer case and front and rear differentials have failed - bmw claims lifetime fluid which is clearly not accurate

Description of the Problem: At ~57,000 miles, the front differential on my 2025 BMW X7 M50i failed and was replaced by an authorized dealer in March 2025. The issue was believed resolved, but in October 2025 the vehicle was returned to Advantage BMW because of a question about when the vehicle showing shuttering, vibration, and binding during low-speed turns. The car has been at the BMW dealership since 10/15/2025, where it was diagnosed with a transfer-case failure. Both failures occurred without any warning lights, messages, or diagnostic alerts. The symptoms were only mechanical noise (front differential) and driveline vibration (transfer case). The dealer confirmed that BMW issued Service Bulletin SIB 27 02 20, describing similar transfer-case/driveline malfunctions. The failed components are available for inspection. This issue poses a safety hazard, as the xDrive AWD system controls traction and stability. Sudden drivetrain failure without warning can cause loss of power distribution between axles and loss of control during acceleration, turning, or highway driving. Multiple owners have reported identical failures on the BimmerPost G07 X7 forum (https://g07.bimmerpost.com/forums/showthread.php?t=2011112), indicating a broader defect pattern. Summary: Two major drivetrain components—the front differential and transfer case—have failed on my 2025 BMW X7 M50i under 60,000 miles with no warning indicators. The vehicle has been out of service since 10/15/2025. Given BMW’s acknowledgment in SIB 27 02 20 and widespread owner reports, this represents a potential safety-related defect requiring investigation.
