2013 Mazda CX-9 — Should You Buy One?

Typical asking price: $8,000–$14,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

The first-generation CX-9 with a Ford-derived 3.7L V6 — a good-driving three-row that's now cheap. The water-pump and transfer-unit homework is real, and rust is the enemy in salt country. A lot of family SUV for the money with eyes open.
