I tried one on a Dodge Ram I owned from the second it rolled off the car carrier. It said a "major repair was made" BS, I never even hit a bug with that truck. It never said exactly what it was. I think they do this to draw you into a full, paid, report. Now I sold the truck to a friend with 190K on it so you know it was a good truck otherwise I would have traded it in. I sure would hate to have to explain a problem that never existed.
