The clock in mine also change’s time (both hours and minutes) at random. At the same tme the cluster and head unit flash and changes language and reverts to Km/h.
This has been going on since the first couple of months of having it. The dealer said at the time they’d look at it at when the car was first serviced. It was serviced last week and I was fobbed off. I haverequested an early termination, mainly because I should have had another auto but, to be honest can’t wait to get rid!
