Brought in my 2014 Silverado for a recall fix (something to do with transfer case); I really can't say much about the work done so I'm assuming it was done properly (hopefully I won't find out the hard way). My beef is that I took pains to keep my truck clean and shiny (it's brand new after all) but when I picked it up, it was all muddy and dirty. My guess is that after the fix it was taken for a test drive over some back roads that's why it got so muddy. When I saw it at the parking lot after I picked up the keys, I didn't have time to go back and point it out because I had to be somewhere else that day.
