I will give you the cost line because it is a big factor in deciding which materials are used in an application. I know, because I am intimately involved in these decisions.
Why limit your discission to pins? Why not make all parts on a car out of stainless steel? I mentioned cost. But theere can be other factors as well. If you look at stainless in the galvanic series, you's find it would cause the adjacent touching steel components to rust quicker, and even more so if it contacted aluminum. Then there's the issue of sensitization of parts that are either welded or processed incorrectly.
That's why you have pins that are steel that is hopefully zinc or Dacromet coated.
