This is a 2019 M3, HW3, FSD, dual-motor with about 9500 miles. About 1/4 mile into my homeward commute, in the pouring rain, while on the phone in-car, the phone connection and all sound suddenly stopped. No voice dial, I redialed manually and finished the call on the handset. After that I noticed that the auto wipers didn’t turn on at all, in a pouring rainstorm, so I turned them on manually. Then upon getting onto a main road where I usually activate TACC the error message, “Cruise control not available” came up. Also, there were no traffic displays on the screen; the cars, orange cones, wayward trash cans, etc. had all disappeared. The ultrasonic sensors still worked and displayed their perimeter circles. GPS nav mapping and routing, including traffic, all worked.
Once home, I rebooted the GPU (both scroll dials down), powered off / on from the screen, and then powered off / on with the scroll wheels and brake pedal. Drove around the block and no joy }<.
I’m letting it sit overnight so it goes “to sleep”, and I’ll see what’s up in the morning. It’s not plugged in.
This is the second time this has happened, although slightly different than the first time — The GPS nav failed and the map was frozen along with all of the above. Both times at about the same spot as I headed home.
Anyone have similar experiences or advice?
