    ELECTRICAL SYSTEM:SOFTWARE · SEAT BELTS

    BMW of North America, LLC (BMW) is recalling certain 2019-2022 330i, 330i xDrive, M340i, 2022 430i Coupe, 2021-2022 430i, M440i Convertible, and 2020-2022 228i xDrive Gran Coupe vehicles.

    Risk: An audible chime that does not properly alert the driver to fasten their seat belt increases the risk of injury in a crash.

    Remedy: Dealers will update the receiver audio module software, free of charge. Owner notification letters were mailed October 12, 2023. Owners may contact BMW customer service at 1-800-525-7417.

    Several months ago, my digital cluster on my 2020 330i blacked out briefly and came back on. The other day, after temporarily disconnecting the batter and correctly reconnecting, the digital cluster and driver assist items all failed. Because of this failure, I no longer have access to my speedometer, engine temperature, or engine lights in the event that something needs immediate attention. Not having the speedometer requires me to check my speed using a GPS device would…

    Car manufacturer (BMW) has had a recall (ID 25V636000) for over two months. It requires parking the vehicle outside away from overhanging trees, because of risk of fire. BMW knows what the fix is (replace the starter motor) but has not begun recalling vehicles. Please compel BMW to perform the repair/replacement.

    Urgent fire risk when parked recall as of September 23, 2025 and received this safeyy recall letter in November 2025 along with 'remedy is unavailable.' Called local BMW dealership today and no remedy and no clue as to when will be available. Urgent fire risk safety recall that is 4 months without a remedy?! Is this acceptable? And no communication or updates available is very frustrating for a vehicle that is used daily for family, children, and work purposes. Please advise.

    Re: 25V-636 We received a recall notice for the above notice over a month ago. No further communication has been sent from BMW in the status of new part availability and they refuse to assist with accommodations because of the scale of the recall. The letter clearly states that there is a fire risk and to not park near structures. This leaves almost everybody who owns affected cars with no option but to put themselves or someone else at risk of this car catching on fire -…
