My 2014 Volt gets parked outside in my driveway which has a slight slope. When parked, the front of the car sits higher than the rear. Following a rain, when I open the front doors, water pees out of the drain holes at the front of the doors. I am concerned that my doors are going to rust along the bottom from the inside-out. I could not find anything related to this issue on this forum. I suppose that I could drill drain holes at the rear of the doors, but I would end up creating freshly-machined metal surfaces that would be difficult to protect from corrosion. Any thoughts?
