Our 2011 has been to the dealer once . it has been on the road almost every single day since we had the vehicle. Has 148000km on it. It is a no drama vehicle. No drama on the highway no drama on the dirt (all grip) and no drama in the snow. With blizzacks the thing is a tank in snow. The awd, stability control and abs really work well together. The engine and tranny have been excellent.
Changed the 2 font tie rod ends,, back brakes twice, front brakes once. At 160k it will need plugs, front brakes, struts and shocks and all the fluids changed. It will be good for another 100000km
Now what to look for when test driving is road noise. That is a sign of either a bad bearing or a ptu (power tranfer unit fwd to awd) failure. I replaced the bearing in the back and it was a pita to replace. A ptu failure is very expensive to replace.
Once you decide on one take it to a ford dealer and get it checked out. Get them to check the ptu the rear bearings, the tie rods, the brakes and tires You should try to find an edge with less mileage on it. I think at 160 k you can expect some suspension and drivetrains parts need replacement. Tell them to remove the ptu fill plug to see the condition of the oil and to see if there are metal fillings.
