Every time I wash my car and after it sits for a few hours, the car does not start, it is dead. Thes last time my computer screen did not come on so I had to place my battery charger on the car. After a few minutes the computer screen came on and the car started. I only experience this after I washed my car. Has anyone else experienced this? I have not taken it to the dealer yet because I'm not sure what to tell them.
