2016 Kia Sorento vs 2016 Mazda CX-9
Two midsize SUVs, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2016 Kia
Sorento
5/10
The 3.3L V6 SXL is a genuine hidden-gem family hauler; the 2.4 GDI and 2.0T are engine-grenade lottery tickets you don't want to play.
VS
2016 Mazda
CX-9
6/10
The best-driving 3-row crossover of its era, undone by a coolant-into-cylinder-head issue that shows up right around the time the warranty runs out.
Milo scores the 2016 Mazda CX-9 higher — 6/10 against 5/10.

If you buy one, buy this one
✅ 2016 Kia Sorento
2016 Sorento SXL V6 AWD, one owner, service records showing 5k oil changes, all recalls closed (especially KSDS, shift cable, and tow-hitch fire), under 100k miles, with the 5-seat configuration for better cargo. Bonus points for the panoramic roof + Nappa combo.
✅ 2016 Mazda CX-9
2016 Grand Touring or Signature AWD with the 2.5T engine and a documented cooling-system inspection/head gasket service history — the AWD system and turbo torque make this the sweet spot, and Signature adds Nappa leather/rosewood trim that feels genuinely upscale.
