Q: Multiple electrical malfunctions, but solution cannot be found. 2015 Volvo XC60.

I purchased a car that had been previously driven by a sales manager for 6,500 miles. Since then I have complained multiple times to the dealership about several electrical malfunctions. One of them is the side-view mirrors independently moving. Last week I was on the interstate and the side mirror retracted when I adjusted the back of my seat (driver’s seat). The dealership has continually told me, each time I have gone to them, that they can not find any electrical problems with my car. Another problem is the tire pressure indicator which shows low tire pressure when the pressure is at regular level. They do say that there is a problem with the tire pressure sensing system so I will have that replaced. However, this leaves me with the malfunctioning mirror problem which can be very dangerous. What needs to be done to correct this?
