Reliability report · 2025 Mazda CX-90 · Updated August 2026

The file shrinks tenfold, but the same storms echo — and the steering complaints now have no recall behind them.

On paper the 2025 is the launch year washed clean: most of the software that bricked and confused 2024s was fixed at the factory, and the recall list drops to two — 24V814 (the startup electrical-supply software, shared with 2024) and 25V568 (the mild-hybrid fuel gauge that can read wrong enough to strand you). The complaint file tells a subtler story. The plug-in's 'electrical leakage' shutdown storm still appears — seven of the thirteen plug-in-filed complaints, several on cars with under 300 miles, with repair parts on months-long backorder. And steering complaints (notchy, binding, sticking mid-turn) continue on a year that recall 24V022 does not cover, which means a 2025 with the symptom starts from zero at the service desk. NHTSA's vehicle page lists one open investigation for this year.

The rest is carryover with paperwork: rear brake squeal loud enough that Mazda opened CSP14 — a Customer Service Program extending rear-brake warranty coverage across 2024–2026 builds through mid-November 2025, with reimbursement — phantom emergency braking reports that this year's owners note their cars weren't recalled for, a transmission grunt on the 1st-to-2nd shift that Mazda calls operating-as-designed, and two dealer-documented cases of tires worn out by 16,000–21,000 miles on this 5,000-plus-pound machine. Nothing here is walk-away economics — it's all warranty-era — but the homework list is specific.

Chirping

What that means: 37 federal complaints against the 2024's 410, and two recalls instead of eleven — the second year is where Mazda's software catch-up shows. Chirping rather than Calm because the launch-year clusters didn't vanish, they thinned: plug-in shutdown storms still bricked some nearly-new cars, sticky-steering reports continue on a year the steering recall doesn't cover, and the rear-brake and phantom-braking patterns carried over with programs, not fixes, behind them.

  • 2.5L PHEV

The 2024 PHEV's signature failure carried into early 2025 production: warning cascades — 'Hybrid System Malfunction', 'Critical malfunction: electrical leakage detected' — then a car that won't drive or shift out of Park. The 2025 complaint file has cars bricking at 25, 126, and 216 miles, flatbed tows (the hydraulic park lock means no neutral with the system down — the car gets dollied), and dealers holding cars for weeks against backordered parts. One complaint reports a hybrid battery replaced under a campaign and failing again within a month. Recall 24V814 covers part of the electrical-supply software on 2025s; the 2024-only campaigns (23V719, 24V815, 24V817) don't apply here, so a 2025 PHEV's protection is its factory software level plus the warranty. Any 'hybrid malfunction' history on the CarFax deserves the full story before money moves.

This is a 2.5L PHEV problem. The 3.3L Turbo I6 mild-hybrid doesn’t share it.

Sticky steering without a recall to lean onmoderate

Notchy, binding, sticking steering — the 2024's headline cluster — appears in the 2025 file too: a wheel that binds in left turns at 30–50 mph and worsens over days, sticky response that won't self-center, steering that 'locks' at full radius. The difference: recall 24V022 covers only 2024 builds. A 2025 showing the symptom has no campaign number to cite, and complainants report dealer visits ending in 'could not duplicate.' NHTSA lists one open investigation on this year's vehicle page. Same advice as the 2024, with higher stakes: do the full-lock parking-lot test and treat any catch or bind as a real defect negotiation, not a quirk.

Rear brake squeal — now a named coverage programminor

Loud, persistent rear brake squeal shows up across the 2025 file, with dealers telling owners it's a known issue awaiting a fix — one owner was told parts and remedy simply didn't exist yet. That changed in spring 2026: CSP14, a Customer Service Program (the industry's quiet warranty-extension mechanism), extends rear-brake coverage on 2024–2026 CX-90s built through mid-November 2025 and reimburses past out-of-pocket rear-brake repairs. Parts were still catching up at the program's launch. A squealing 2025 is annoying but covered — confirm the VIN shows CSP14 eligibility and get the claim on record.

Phantom emergency braking, outside the recall's fencemoderate

Multiple 2025 complaints describe the automatic emergency braking firing at nothing — railroad crossings, freeway ramps, reflections — sometimes several times a week, with at least one complainant noting their VIN isn't covered by the recall (24V349 reprogrammed 2024s). Dealers respond with 'operating normally' or can't reproduce it. It's a known-shape problem on this platform with a software history, so a 2025 doing it deserves a firmware-level conversation with the dealer, not a shrug. Test it: drive past parked cars, under overpasses, and through a tight ramp on the test drive.

Tires gone by 20,000 miles — twice documentedminor

Two independent 2025 complaints report full sets of original tires worn out prematurely: one dealer-measured at 21,586 miles (rear at replacement threshold, Mazda case number on file), one at roughly 16,500 miles with Mazda representatives verbally acknowledging weight-related wear, per the complainant. Two reports is a signal, not a statistic — but this is a 5,000-plus-pound vehicle that works its front tires hard, so on any used 2025 check remaining tread depth and factor a full set into the first-year budget if it's thin. Uneven or premature wear is also worth a four-wheel alignment check, given this platform's steering file.

Second-year improvement is real: 410 complaints became 37. But a 2025 with a notchy wheel can't point to a recall — the steering campaign stopped at 2024.

Before you buy

Print this
  1. 01Pull the VIN's recall status: 24V814 and (on the I6) 25V568 should both show completed — the fuel-gauge one matters more than it sounds, since it can strand you at an indicated quarter tank.
  2. 02Do the full-lock steering test in a parking lot; on a 2025 any binding or sticking has no recall behind it, so treat it as a negotiating point or a reason to walk.
  3. 03On a plug-in: read the service history for any 'hybrid malfunction' or 'electrical leakage' visit, ask what software level the car is on, and confirm how long the dealer held it. A one-visit-and-clean history is fine; a saga is not.
  4. 04Listen for rear brake squeal and confirm CSP14 eligibility on the VIN (build date through mid-November 2025) — coverage and reimbursement exist; use them.
  5. 05Test the emergency braking behavior on the drive: past parked cars, under an overpass, up a ramp. Note any false alert and raise firmware history with the dealer.
  6. 06Check tread depth on all four tires and ask for alignment records — two dealer-documented complaints put full tire replacement under 22,000 miles.
