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 causes me to divert my attention from the road which is a hazard to pedestrians and drivers alike. I also do not have the driver assist items which can result in an accident which would injure both myself and other drivers. The cluster has not returned to being functional, which was confirmed by the dealership after completing a full ISTA troubleshooting tree. There were no warnings that this would happen, it just immediately died after a power cycle of the battery.

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.
