Yes had this twice and in both cases in the middle of no where . No mobile signal either. On both occcasions, I got out of the car, zapped it locked . Gave it a few minutes and it was ok but worrying. This was then followed by a display of slipping gears ... where in reverse the gear was picked and dropped picked and dropped, so although you could get motion it was stuttering. Did same as before , out, zapped locked and, like yours, the fault had cleared itself. Took to dealer. they had it for two days , allegedly did software reboot .upgrade and otherwise No Fault Found. It has been ok since but you can't feel confident it won't happen again. Out of interest the first time this happened , I was doing some dodgy parking , backwards/forwards, backwards/forwards and it was after that I got N in every gear position. Another more recent one to watch out for. I had tyres changed (30,000m), garage forgot to reset the tyre pressure monitor, so I took it back in. They spent an hour resetting it and said they had had problems, but, it was ok now. Got home , no problem. Locked the car, no problem. Next day zapped open ok, got to work and zapped locked, ok. Came to leave work and key remote would not activate anything. Wouldn't re lock or unlock doors or tailgate. Fortunately I tried the 'normal' key to open the door which worked but set the alarm off ( dealer said it wouldn't be it did). Once opened, zapped and been ok since. Dealer advises I carry the spare key everywhere !!
