May have been answered before but I have a strange thing happening. Just got a 2016 300; senior owned and dealer serviced with 60K miles. Some good size scratches in the paint I'm touching up but it takes time as it's a daily driver. Max steel paint so it shows everything and I'm trying to keep it as clean as I can to polish it out and seal the paint. When I wash it with a hose or at the car wash the back side marker lights come on with the headlights. After a minuet they go out until I spray it down again. Is the waste spraying on the door handles making the car think I'm opening the door? I don't know what else it could be; never had a 300 before. Am I nuts or is my car possessed?
