The first time it happened was after I took him on a trip to Cleveland a week before Christmas and I chalked it up to temp changes going from warm house to cold truck, then truck getting warm. Nope. It keeps happening every 5-13 days since and I haven't taken him out again. So, yeah, that's why I've thrown in the towel on it. It doesn't seem to be anything I'm doing, and I can't solve it. The other 3 can stay in useand having Satan for extra parts is fine. But, if he ruined a mod, I would be really mad, so he got binned.
