2022 BMW X7

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 vehicle had a spill in the cup holder. The cup holder has holes and does not hold liquid. This spilled into the electronics underneath and around it. The car suddenly could not be put into park. It would roll when attempting to do so. The electronics control park and the emergency brake from the same electronic panel. Preventing save disabling of the vehicle required chalking to prevent movement.

The steering wheel locked in position while driving. The vehicle would not turn, which almost caused an accident. Warning lights came on: Evasion Assistant/Steering Assistant. Once the car was pulled over and restarted, the warning lights temporarily stopped but returned and malfunctioned again. BMW confirmed that there was a steering malfunction and found that a leaking water pump infiltrated the steering rack and electrical harness which created the steering system to malfunctioned. BMW only approved replacing the water pump. The technician stated they recommended replacing the steering rack and electrical harness, but BMW said for them to test drive for 20 miles, if no error pops up then return the vehicle back to the customer!

While driving on interstate 10 near New Orleans, the computer software system malfunction resulting in loss of power steering and 90% loss of braking action requiring a great distant to stop.Vehicle was towed into shop and was found to have 184 codes violated. No parts were replaced. only an update. if this would have happened in traffic , I would not have been able to stop for 1,000 feet.
