@Phaedra I’ve had my 85 for a few months now and like you have had several error messages appear. I’ve had traffic sign recognition error suck at 30mph in a 60mph with malfunction warning, drive error, left rear indicator failure error, SOS malfunction, 12volt battery error, all radio stations gone, car not unlocking with handle and last week I had 5 error messages when driving but I didn’t get to read them all !!
They all clear themselves or a stop and restart clears them. Oh and the car seat easy access only puts the seat back to the correct position about 50% of the time. If it was just me I’d be back at dealership but all these errors seem common on the Facebook pages regarding the 85 which is sad because the car is great otherwise !! Also they are all intermittent and dealer would probably say it’s not doing it now.
