Hi - I have a 2015 XF Portfolio and I have a list of electrical issues that have started over the last couple of months. Wing mirrors won’t close, rear windows won’t open at all, steering wheel moves in/out & up/down, without warning, the boot only opens with the button on the dash. I am getting a battery low warning - would that be causing the issue? I know nothing about cars by the way! Go easy on me. Thank you in advance for any replies or advice.
