Reliability report · 2023 Mazda CX-9 · Updated July 2026

The quiet final year — the engine drama is behind it, and the file is small and scattered.

The 2023 is the final second-generation CX-9 (Mazda replaced it with the CX-90 for 2024). Its file is small and diffuse — no cracked-head coolant leak, no oil-consumption cluster. The scattered recent notes include a hard/low brake pedal one owner chased through multiple dealer visits, an electric-power-steering (EPS) failure with a failed u-joint shaft and bearing (owner cites TSBs 06-001/20 and 06-001/24, with a roughly $2,000 EPS replacement), a spontaneous sunroof shatter, and the familiar i-ACTIVSENSE driver-aid faults.

One manufacturer program touches 2023: SSPC8, a Special Service Program (not a safety recall) for a remote-tuner module whose outdated software can let the 12-volt battery drain if the car sits unused — a fix worth confirming was done, but not a defect to fear. This is a Calm, buy-on-condition year. One caution: our automated 2023 recall check did not return cleanly — do a direct VIN recall lookup before buying.

Canary status

Calm

What that means: 12 federal complaints — one of the smallest files in the range — and no confirmed safety recall for 2023 as of this check. The last year of the second-generation CX-9 before the CX-90 replaced it. No cracked-head or oil-consumption cluster; the recent notes are scattered (brake feel, an electric-power-steering failure, sunroof shatter, driver-aid faults). A settled send-off that rewards a normal careful inspection.

Electric power steering (EPS) and brake-feel one-offs

moderate

The two mechanical notes that stand out in a small file. One owner reported an electric-power-steering fault — a 'thud' from the wheel traced first to a failed u-joint shaft, then to a failed bearing in the EPS unit requiring full replacement (they cite TSBs 06-001/20 and 06-001/24 and an EPS replacement quoted over $2,000, partly covered as goodwill). Separately, another owner chased a hard/low brake pedal through four dealer visits with parts replaced and no clean fix. Neither is a recall or a documented fleet-wide pattern at this volume, but on a test drive pay attention to steering feel/noise and brake-pedal firmness, and pull codes for any stored steering or brake faults.

Remote-tuner battery drain (SSPC8 — a program, not a recall)minor

Mazda ran SSPC8, a Special Service Program (a manufacturer fix campaign, not a safety recall) covering certain 2023 CX-9s (and other models) whose remote-tuner module shipped with outdated software; if the car sits unused for a while, the 12-volt battery can discharge. The fix is a software update. It's worth confirming SSPC8 was performed, especially on a car that has sat, but it is a convenience/no-start nuisance, not a safety defect.

Driver-aid faults and sunroof shatterminor

The familiar low-frequency items carry into the final year: i-ACTIVSENSE Smart Brake Support / forward-collision false activations and, occasionally, a stored malfunction affecting acceleration; plus a spontaneous sunroof shatter (a burst with no impact) that appears across several CX-9 years and is usually not covered as glass. Test the driver aids on the drive and inspect the sunroof/glass.

The 2023 is the send-off year: a tiny complaint file, no big engine pattern, and the reliable end of the second-generation CX-9.
