Just like to update on the mirror. The dealership were real good. Replaced the motor assembly inside the mirror. I did asked if this has been a problem with the cx5, but the guy I spoke to said no, the only other one he had heard of was on a Hyundai.
But when my wife went to pick the car up the girl at the service desk said there had been a "few" in with similar fault. So hopefully ours was just a one off.
Still a fab car.
Thanks.
