Too bad Ford is that way, I have a Camaro in my bay right now with a spun rod bearing. We put a clutch in it at 5k miles, there are all kinds of signs of abuse, but we checked to see if it had a factory calibration in it, which it does, so now I get to replace the crank and rod. Stupid crappy 3.6L with a teenage driver and I have to keep warranting shit.
and as for Ray's truck, I've seen a few doing that with the undercoating but nobody has bitched about it around here so we haven't fixed any.
