A cautionary observation for Atlas owners who drive in winter conditions where sand, salt and other chemicals are used on the roads. After taking my new Atlas through the car wash, I was surprised to find a large accumulation of road grime (sand, salt, snow) trapped in a channel along the inside bottom edge of the doors. The car wash spray didn't clear it away. That area is metal which creates the opportunity for corrosion and rust to form. Outside of spending $1,000+ on adding the running boards, it requires a regular stop at a wand wash to manually spray away the potentially corrosive substances that get trapped in that channel. Really enjoy my Atlas and would like to drive it for many years to come.
