2017 MAZDA CX-9 Complaints and Recall Information
The 2017 MAZDA CX-9 has 6 complaints and 0 recalls filed with NHTSA. Owners most frequently report issues with coolant and oil leaks related to the engine, particularly involving the cylinder head. Several reports describe sudden overheating and loss of power while driving on the highway, sometimes accompanied by smoke and warning lights. There are also complaints about intermittent failures of the infotainment screen, affecting backup camera functionality.
Common Issues- Coolant and oil leaks. Multiple owners report leaks from the rear of the engine linked to a cracked cylinder head caused by the turbo proximity to the head.
- Overheating and engine failure. Vehicles have overheated suddenly while driving at highway speeds, causing loss of power, acceleration, and the car to emit smoke. These incidents often occur without prior warning lights or indicators.
- Cracked cylinder head defect. The defect causes coolant and oil loss during driving, creating dangerous conditions. Mazda acknowledged the issue and extended a warranty program, but some dealers refuse to repair vehicles if the driver did not immediately stop after symptoms appeared.
- Infotainment system failure. Screen goes black 10-12 times a year, leading to loss of backup camera access until the vehicle is restarted. This problem has persisted over several years of ownership.

2017 MAZDA CX-9
ID: 2110989BACK 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.

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 he was unaware of the known issue these cars have with the cylinder head. The problem has been confirmed by Mazda and they notified me within the month of March of the problem and the extended warranty to replace the known manufacturer defect cylinder head. The Mazda dealer now has my car and acknowledges the cracked cylinder head caused the problem but said because I didn’t immediately stop on the highway and kept driving until I got to a safe location I was negligent and are refusing to fix the car which now has a blown engine, etc. it is available for inspection now at the Mazda dealer. My safety was put at risk because I could have died on the highway if the car completely stopped working, it was dangerous driving it when it first started happening because it started out of nowhere the car was fine I was driving 50+ mph and it started smoking, overheating etc. I could have also killed someone else. It is a disgrace that not only they won’t fix my car they want to say they won’t because I’m negligent? I drive my kids to and from school everyday do you think I’m going to risk their safety in an unsafe car? They should not only fix the car but compensate me for putting mine and my children’s lives at risk. A complete disgrace.
