2020 XC40 T5 Momentum. Purchased new in February 2020. 5,500 miles. Sensus Connect Touchscreen Center Display.
Upon unlocking and entering the vehicle, a loud pulsating and ryhthmetic buzzing came from the audio sound system. Media would not work. Phone would not connect. Could control buzzing sound with volume control. Vehicle would start, but blinkers and rear Back-Up sensors would not function. Turned vehicle Off-On three times. Everything returned to normal. No error codes emitted. Called Dealer. No help. Never heard of this happening. Any ideas?
