Service bulletins for the 2023 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.

Bulletins, newest first
B6404222024-03-02. 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.
B5108192024-02-01. Service bulletin. VISIBILITY:POWER WINDOW DEVICES AND CONTROLS; ELECTRICAL SYSTEM. The basic conditions for initializing the power windows are not met.
B5404212023-11-01. Service bulletin. VISIBILITY:SUN/MOON ROOF ASSEMBLY; STRUCTURE. This situation can result in two customer complaints: 1. Wind noise 2. Excess water entry
B6102202023-09-25. Service bulletin. VISIBILITY:WINDSHIELD; VISIBILITY:WINDSHIELD WIPER/WASHER; STRUCTURE. ?When driving over uneven pavement or cobblestones, a knocking noise is present from the passenger side front area (A pillar). Once the vehicle is driven on a flat, even surface; the noise is no longer present.
B5401232023-09-25. Service bulletin. STRUCTURE; VISIBILITY:SUN/MOON ROOF ASSEMBLY. ?Water leaking into the vehicle from the headliner/microphone area.
B5117222023-06-26. Service bulletin. VISIBILITY:REARVIEW MIRRORS/DEVICES; ELECTRICAL SYSTEM. Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller. That one provides an imprecise voltage measurement, which the main controller interprets as a fault.
B5108232023-06-26. Service bulletin. VISIBILITY. Upon opening or closing (i.e., folding in or out) the exterior mirror assembly, a creaking sound is heard from either the driver and/or passenger side.
SIB5117222023-05-15. Service bulletin. UNKNOWN OR OTHER; ELECTRICAL SYSTEM; VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR. Due to the semiconductor supply, the Local Interconnect Network module in either of the exterior mirrors was switched to another controller.
