2016 Hyundai Santa Fe 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 Hyundai
Santa Fe
6/10
The 3.3L V6 Santa Fe (XL) is the one worth owning; the 2.0T/2.4L Sport is a Theta II lottery ticket you don't want to play in 2024.
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.
Dead heat: both score 6/10. The tiebreaker is which specific car you find.

2016 Mazda CX-9

If you buy one, buy this one
✅ 2016 Hyundai Santa Fe
2016 Santa Fe (3-row, NOT Sport) Limited or Ultimate with the 3.3L V6, in FWD, with under 100k miles, complete Hyundai dealer service records, and the KSDS/ABS recalls already performed. Bonus if it's a one-owner Southern-state car with no rust on the rear subframe.
✅ 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.
