X is at 75k miles. It's at the dealer. The water pump (second one in the last 40k miles) and and cooling fan clutch needed to be replaced. So far every dealer we've left the X with has had nothing but positive things to say about ease of dealing with WD. Same goes for the experience on our part, with them. We're VERY close to breaking even on the warranty.
Cliffnotes: Warranty Direct HIGHLY recommended
