I spoke too soon about working the gremlins out. I now have a transmission rebuild kit on order at my dealer.2019, 85K. I've had the cam phasers replaced, the rear diff serviced, the moonroof replaced, and the rear windshield wiper fluid tubing replaced. I have not had to have it in for service in quite a while now. I am hoping that I have gremlins worked out and can put another 85K on it before buying another vehicle.
Timing chain kit phasers at 150,000 not a problem sinceI take good care of my 2018 Expedition purchased new. I have my dealer perform all factory recommended maintenance, many items earlier than recommended by Ford.
Currently have 85,000 miles and the truck looks and drives like new. Any comments out there about being able to use this truck reliably to 150k miles or beyond.
Done cam phasers twice, replaced heater hoses, new serpentine belt, new battery, new thermostat and water pump. At this point the catalytic converters and turbo’s are original.
Maintenance wise, done rear brakes twice, fronts are still original but close to needing replaced, change oil about every 4K miles, flushed transmission, replaced spark plugs, done dealer emission maintenance a few times, changed transfer case oil. I have never had radiator flushed, however with replacement of cam phasers, heater hoses, water pump and thermostat, plenty of new coolant has been added.
Next service I will have front and rear differentials drained and replace lubricant.
Be interested in others who have high mileage on their trucks and cost to maintain over 100k miles.
What thermostat you replaced with? If your new thermostat is the 180F RT1258, which has been widely discussed here, you may not have CDF drum failure again coz the tranny oil temperature is significantly lowered.I’m hoping I’m just down to an oil pan re seal and maybe Ford will step up and turn the CDF drum TSB into a recall and then I’d really feel the gremlins have been worked out if this truck. I wish I knew if the later CDF drums were improved but the new part really looks to fix that issue since the bushing cannot shift and is locked in. Some people say “oh well it’s a 2018 and first year of production” but besides the plastic oil pan, all the 2018-2021’s seem to have these issues.
Luckily, the suspension is all super tight and the ride is still very good.
I have the 180 after seeing how hot it ran when I got it but hate to say even though trans stayed around 190-195 it still failed! Could have been pre damaged from all the time running at 210 or more but hard to say. If I keep the truck I might try an air to fluid exchanger and get the fluid lower and see. That plus a Mishimoto radiator are on my list but I’m really thinking of selling it since I don’t need so much room anymore and the kids have their own cars.What thermostat you replaced with?
