I had mine go out on my 2001 and took it to a dealer when I was out of town, visiting family. I had no idea what it was, and when I got the truck back, it was clearly marked as a warranty item, and total cost to me was $0. 00. When I got home, I posted here about it, and lots of people responded that they had just received their recall notice from DC. This was back in Spring 2001, so just about 2 years ago now.
