How this compares
126 complaints is 2.2 times fewer than the median 2018 model on this site and 2.6 times fewer than the median 2018 SUV. Among the 2 CX-9 model years here it ranks 1st for complaints. Counts follow sales volume as much as reliability, so a truck that sells 700,000 a year draws more reports than a sedan that sells 200,000.
Complaints filed by year
39 complaints came in 2023, 1.9 times the year before. Owners file in waves when a problem gets press or an investigation, so a spike measures attention as much as failures.
