While I'm leary to finance a German vehicle (we lease my 340i), it seems to get pretty good marks for reliability and I'm thinking that this being the last model year of the X5, the 2018 we're looking at would represent the peak of reliability for that model. Also, for anyone who has an X5, any experience trailering? I'd be towing my S2000 on a flat/open trailer to the track about 5x per year.
IMO, of all X5 generations this one was a let down, and that is not because of reliability.
IMO, it drives worst of all of them. Feel in F15 compare to E53 and E70 is non existent as in those two models you knew exactly what your wheels are doing (though people complained about weight of steering wheel). F15 electric steering is abysmal, and many other manufacturers did much better job. When I was on a market for X5 I was shooting for F15 3.5i but once I tried it, I decided to get 2013 E70 35d. IMO, E70 drives light years better.
Brakes on F15 are tuned differently for North American market as BMW decided to go with customers who hate dust and value opinion of neighbors more then performance. So you will get cermaic pads. Good news if you want performance is that pads from E70 fit F15, so you can get dusty, dirty pads from that model that react just by looking at them
On positive side, 8 speed ZF in F15 is a gem. It will outrun much stronger SUV's since a. BMW shed some weight from F15 compare to E70, and b. No one is even close in programming transmission the way BMW does it.
Also big thing IMO< is that with F models BMW finally returned to oil temperature gauge.
Reliability? BMW improved reliability in F15 dramatically. First of all, diesel models have 2nd generation SCR system. Still based on personal experience with E70 and stories I heard from F15 35d owners, avoid that model due to SCR. It is a shame as diesel is great.
V8 TT n63 is dramatically improved and now carries designation N63TU. They improved turbo cooling, changed valve stems supplier etc. My SA here at BMW told me that it is pretty reliable.
Best option is N55 3.0 twin scroll turbo. Get ready for new water pump between 50-80k depending whether car will see most city driving (short life span) or HWY. Pump is pricey and if you do not want to change it at dealer find reputable shop as it is tricky to handle it. It must be properly stored as bearing is made out of graphite, stored in upright position and once opened drenched in water. Before installing it needs to be wet, and one needs to make few rotations while water is inside. That pump is the reason why BMW went with old fashion pump on B58 engine.
Also, gasket on oil filter housing is sometimes leaking. Other then that, engine does not have any other issues.
At 60 do transmission service, meaning change filter pan and release fluid (do not flush) and just add what got out (that is how ZF recommends to be done).
Brakes are not expensive. Do not be fool to change at dealer. I paid for E70 35d (has bigger rotors then F15 35i but same pad design) pair of Brembo front rotors $120 at FCPEuro when they had sale, while Textar pads for front go for $80-100 (same performance as OE as Textar is supplier) and now I have ATE pads and they go for same price as Textar. It seems ATE (also supplier) is bit more aggressive and better performer. Personally I like them more.
Changing brakes on BMW is usually much easier then on Toyota Corolla, so if you are slightly DIY inclined, it will be piece of cake. Rear calipers are electric, but on youtube you can find DIY videos how to put piston in service mode. Not big issue, especially if you have Carly adapter.
I would advise you as it is mentioned to get M trim as it will offer more BMW like drive, however, that trim also comes with POS electric steering. Get carly adapter as you can unlock a lot of European features that are locked for the U.S. market.
Now towing wise, 35d would be best option. But it is your choice whether to roll the dice. 413lb-ft of torque would tow anything, and although X5 is not body on frame, it is much more capable then similar vehicles (though not as capable as Durango, but that is Mercedes GL platform). Diesels in BMW are truly great, best of all Euro manufacturers. But SCR system is going to hoover over your head. It is much better then in my E70. But I saw people complaining still about NOx sensors (though they go south around 90-120k).
