A complaint is an unverified account by the person who filed it, not a
finding of fault. One complaint is one ODI number, which is how NHTSA counts
them.
No recall campaign was matched to this year, make and model. That is not
the same as a clean vehicle: recalls are issued against production
ranges, and the only reliable check is your own VIN.

One complaint can name several systems, so these add up to more than 61.
When the complaints arrived
By the year NHTSA received them
By the year NHTSA received them, which is not the year the failures
happened. They peaked in 2023 at 19.
This is the year the complaint was filed, not the year the failure
happened. The range runs from 2018 to 2026, the last of them a part year, which is why its column is drawn faint.
Crash test ratings
NHTSA New Car Assessment Program
NHTSA has not crash tested the 2017 Mazda CX-9. Its New Car Assessment Program
tests a selection of each year's vehicles and does not reach
motorcycles, heavy trucks, motorhomes or most low-volume models, so
an absence here says nothing about how the vehicle would perform. It
is not a low score.
What owners have reported about this vehicle is below, and it is a
different question: a crash test measures what happens to the people
inside in a controlled impact, while a complaint records what broke
during ordinary use.

ENGINE
I took our vehicle into Mazda due to a coolant leak that could not be located. It had my wife stranded due to the vehicle overheating. Everything lined up with CSP11. The dealership is now stating that the vehicle has a blown gasket and needs an engine replacement. This is the issue covered by CSP11 except that the crack is in the wrong location. They haven't found the Crack but are denying the warranty due to the covered location not being the source. The vehicle only has 93000 miles on it.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
My infotainment screen goes black 10-12 times a year, and therefore I lose access to my backup cameras. I have to turn the car off, and then back on, in order for the screen to function again. This has been happening for the full 8 years I have owned the car. I also have video of this happening, but the file is too large to attach so including photo only.

POWER TRAIN
I was driving the vehicle on the highway when the vehicle started to overheat, lights started blinking, the car was smoking, losing power and acceleration. This car has a recall on the cyclindwr head which when cracks causing the car to loose coolant and oil. If it cracks while you’re driving especially on the highway the car will immediately loose coolant and oil thus causing a very dangerous driving condition. There was no indicator prior to the failure that there was anything wrong with the car. No check engine lights, no coolant lights nothing. Prior to this happening I smelled coolant in the car cabin , took it to my mechanic who tested the coolant system and found no leak. At the time …

If this is your car and a dealer keeps failing to fix it, your state's
lemon law may require the manufacturer to replace it or buy it back. How
many repair attempts it takes, and how long you have to file, is set by
the state you bought in and by nothing on this page.
Complaints: NHTSA's ODI

complaint is one ODI number, which is how NHTSA counts them.

A complaint is one owner's account and has not been verified by NHTSA or by
us. A vehicle with more complaints is not necessarily worse: models that
sold in larger numbers collect more of them. How this is counted.
