Service Brakes
428 of the 1,485 complaints (28%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.
Engine
358 of the 1,485 complaints (24%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.
Power Train
165 of the 1,485 complaints (11%) mention the powertrain. Powertrain complaints can range from rough shifting to loss of drive. We road test, scan for stored codes and inspect fluids before recommending any repair. See our auto repair page.

Most Common Mazda CX 9 Check Engine Codes
Owners often put the exact trouble code in their NHTSA complaint. These are the codes cited most often for the CX 9. The most-cited is P0016 (crankshaft and camshaft position correlation (bank 1 sensor a)), mentioned in 5 complaints. Counts reflect complaints that name a code, not every car on the road.
| Code | What it means | Complaints citing it |
|---|---|---|
| P0016 | Crankshaft and camshaft position correlation (bank 1 sensor A) Can point to a stretched timing chain, a failing sensor or a timing component problem. | 5 |
| P111A | Manufacturer-specific powertrain code The meaning of this code varies by make and model, so it needs to be looked up for your vehicle and tested. | 3 |
| P0192 | Powertrain code A scan and test is needed to confirm what this code means for your vehicle. | 2 |
A code is a clue, not a diagnosis. The same code can have several causes, so we test before replacing parts. See our check engine light diagnostics, and read whether it is safe to drive with the check engine light on.

Keeping a Mazda CX 9 Reliable in Phoenix
Arizona heat is the hardest test a Mazda will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a CX 9 that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for CX 9 owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Mazda CX 9, a pre-purchase inspection shows what the paperwork does not.
