So I had my 2012 QP at the dealer to take care of a older recall to the ECU (update software) the mechanic also tightened a suspension bolt and noticed a small o ring leak(ordered parts for that and a new headlight switch. All was good driving home then after one day not driving it, I tried opening the door with the left button on the handle but nothing. The right button did open the door. Tried starting it and a buzzing noise, dash lights went little crazy and clock started winding fast. No starting. Shop salesman said probably the battery but is new battery 3-4 months old. Any suggestions?
