• 10249027The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle discharged battery complaints.
• 10249018At low outside temperatures (below 40 degrees F) and slow driving speeds (i.e. when parking, maneuvering)with a large steering angle, the front end can be slightly axially misaligned. This can be felt (jerking)/ heard via an acoustic acknowledgement (clunk) as seen at the 11 second mark of the video. See attached video V36 01 21.
• 10249017SITUATION Unusual noises occur only when operating the steering column in the axial direction. 1. A one-time thump sound at the start of movement Shortly after the steering column starts moving, retracting, or extending, a one-time thump noise is heard. See attached video V32 03 23 2. Humming noise while steering column extends in the axial direction. The sound is only heard when the steering column is extended, not when the steering column is retracted. When the steering column starts to move in the extended direction, the humming noise can be heard. See attached video V32 04 23
• 10247567Engine will crank but not start. There is no communication with the integrated fuel module (TFE) whendiagnosing with ISTA. The following two fault codes will be stored in the DME: 032B43 - Low fuel pressure system, electric fuel pump: pressure value too low CDA594 - Message (- 0x33E) missing, receiver DME, transmitter TFE
• 10245422Customers may state that the alarm system (DWA) is not active after locking their unoccupied vehicle. Depending on the vehicles equipment and settings, no acoustic or optical confirmation (folding the mirrors/blinking confirmation) is noticeable. Additionally, the red anti-theft alarm LED in the interior mirror does not briefly flash every 2 seconds, indicating the alarm is armed.

• 10242691?Unusual noises occur only when operating the steering column in the axial direction.
• 10242688?A software error may cause an unwanted pressure pulsation in the transmission during a "Remote Engine Start."
• 10239614The air conditioning cycles from cold to warm air while driving or while at a stand still. The vent outlet temperatures vary by 25 degrees Fahrenheit or more (38 F to 60 F +) without changing any climate control settings.
• 10239611Headlight check control (CC) message 128 "High beam headlight failure" is displayed. The following fault codes are stored during a vehicle test: 80419A - Left high-beam headlight: Short circuit and/or 8041A5 - light outputs: Number of permitted short circuit cycles exceeded
• 10239604A groaning type noise is heard during the height adjustment.
• 10239603BMW AG has issued an Emissions Recall (effective March 17, 2023) on a certain Model Year 2021 - 2023 BMW vehicles that were produced between June 16, 2020, and December 13, 2022. Due to a software failure, there is the possibility that the transmission does not go into "sleep mode" if the car is turned off.
• 10239602A vehicle arrives at your center to be diagnosed for a micro-leak in the fuel evaporative (EVAP) system (NVLD natural vacuum leak detection). For this condition, the following fault is stored in the DME: 190302 - fuel tank ventilation and scavenging air system, micro-leak: leakage more than 0.5 mm.
• 10239601BMW AG has issued a Delivery Stop effective June 6, 2023 on certain Model Year 2023 - 2024 BMW vehicles that were produced between October 26, 2022 and May 8, 2023.

• 10238083Due to a software error, the vehicle sporadically does not achieve sleep mode. As a result, the 12-volt battery becomes discharged and may cause a no-start condition.
• 10238081Upon opening and closing the tailgate, a creaking/groaning sound can be heard from tailgate actuator.
• 10236387Engine Variants Updated.
• 10236236Issues with the various functions of the camera-based driver assistance systems (KAFAS system) can possibly lead to following customer complaints: KAFAS camera system deactivates itself, due to system restrictions that are not clear to the customer KAFAS camera system cannot be activated due to system restrictions that are not clear to the customer Road signs are sporadically not detected.
• 10235206Customer is shown an incorrect GPS location in the vehicle (i.e., Nav Map, coordinates).
• 10235205The 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.
