thought i would add to this thread with some high-mileage details on my 2004 FX35 AWD.. Been in the family since, new, bought it from my dad at 260km.. nobody would give him much money on trade in for it! A shame considering how well it was maintained.. but to my great benefit!
Since warranty was up I've kept track of everything carefully and have spent a total of about $13,000 on all maintenance and repairs, not including tires, since 2008 and 130km. That's around $0.10 a km for maintenance, not too unreasonable. Now I'm in vancouver and maintaining myself, but so far that means living with the weather-dependant door locks, and busted power steering. Otherwise it's running fantastic!
Major repairs:
100km f.pass wheel bearing replaced
130-190km no problems just routine maint.
190km a/c condensor and associated expensive crap
190km new tie rod ends
220km, 230km, 236km 3 remaining wheel bearings replaced
233km battery replaced
240km spark plugs and boots replaced
251km new rear brake calipers
251km front and rear sway bar links
250-260km lock actuators on passenger front & back doors and tailgate very subject to not working at warm temperatures (over room temperature, that's warm here..)
268km power steering died, still to be repaired.. I don’t drive much and strong arming doesn't bother me..
275km alternator replaced
my regular maint intervals..
brake pads about every 30,000km
brake rotors machined every 30,000km and replaced every 60,000km
oil every 5000km
coolant, diff, transmision, transfer case oils every 2 years.
