Heard a lady on CarTalk from Woodinvile, WA that had a Maxima that was turning KM's on her odometer instead of miles. She said the dealership had just gone under (must have been Melody Nissan). Anyway, I think they were bringing a lot of Canadian vehicles down and reselling them. I haven't heard of anyone with this problem on an Xterra, but thought I would post the info.
