- [B010924](/bulletins/11015848.md), 2025-03-21, Warranty extension: ELECTRICAL SYSTEM; FUEL/PROPULSION SYSTEM. The High\-Voltage \(HV\) Battery Assemblys Cell Modules Temperature Sensors \(Internal NTC repair kit\-specific\) limited warranty for defects in materials or workmanship has been extended to 10 years / 120,000 miles as determined from the original in\-service/first delivery date
- [B640422](/bulletins/10250374.md), 2024-03-02, Service bulletin: ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM. An interference noise \(groaning noise\) can be heard from within the heating and air\-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air\-conditioning unit, the kinematics causing it \(top or bottom,left or right\) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors \(and the associated kinematics unit\) varies.Various models use either 2 or 3 servomotors.
- [B510819](/bulletins/10249437.md), 2024-02-01, Service bulletin: VISIBILITY:POWER WINDOW DEVICES AND CONTROLS; ELECTRICAL SYSTEM. The basic conditions for initializing the power windows are not met.

In the 4G network, voice calls will be transferred via the Voice over LTE \(VoLTE\) function. For this purpose, the SIM card must perform an IMS registration in the mobile communication network. Due to a production error, the telematics control units were delivered without an IMS configuration. The Connected Drive voice services \(Concierge Call, BMW Assistance, and emergency call voice\) can no longer be used regionally in the US in vehicle with telematics control units ATM\-1 and TCB\-4G. Voice control of the vehicle and all other telephone \(paired mobile devices\) functions are not affected. Emergency call location data is unaffected.
