Service bulletins for the 2020 BMW X4

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

250 on file from NHTSA, as of 2026-10-19.

B8408222023-05-01. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. The 3G network in the US has been shut down. This means that only the 4G network will be available. 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.
B6516232023-05-01. Service bulletin. EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Customer states there is no audio playback (telephony, navigation, radio) and system sounds (PDC, turn indicators, acoustic signals) may also have failed.
