Platform Heritage

The Mazda CX-9 is a mid-size crossover SUV manufactured by Mazda from 2006 to 2023 through two generations with three-row seating. It was Mazda's largest passenger vehicle until the arrival of the Mazda CX-90. Despite being built in Japan at Mazda's Ujina #1 plant in Hiroshima Prefecture, the CX-9 was never offered in the Japanese domestic market. The shorter and narrower Mazda CX-8 was offered in Japan instead. Production was ended in 2024, with the Mazda CX-90 serving as its successor.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
