I had this with my 2018 XC60, took it to the dealers and they updated the software as they couldn’t find any problem whilst they had the car in. I managed to get a video of it resetting but it didn’t really help. Touch wood hasn’t done it again since. Mine started after I had parked at a busy aerodrome (may be a coincidence), but made me wonder whether the radar/radio signals in the area had affected the car. It’s the only thing I could think of.
