Used Mazda CX-90 Buying Guide: Inline-Six vs PHEV, 2024-2026

A used Mazda CX-90 is a good buy in mid October 2026 if you get a 2025 or a well-documented 2024 with every recall closed, and the regular 3.3-liter inline-six is the safer pick than the plug-in hybrid unless you will actually charge it most nights. The CX-90 only goes back to the 2024 model year, and that first year carries a long recall list, so the VIN check matters more here than on most three-row SUVs. Expect a nice cabin, a firm ride, and a third row that is really for kids.

Mazda introduced the CX-90 in a January 31, 2023 press release as a 2024 model on a new platform, and it said in a June 30, 2023 notice that the CX-9 would end in the U.S. after the 2023 model year. So these are two different vehicles, and a seller who calls a CX-90 "the new CX-9" is only half right. If the budget does not stretch, our used Mazda CX-9 buying guide covers the older truck, which is cheaper and simpler.

How the CX-90 differs from the CX-9 it replaced

The CX-90 moved Mazda to a longitudinal, rear-biased layout, while the CX-9 used a transverse platform and a turbocharged four-cylinder, according to Car and Driver's report on the CX-9's end. That same piece noted the CX-90 started at only a little more money but its top trims reached past $60,000 new, about $10,000 above where the CX-9 topped out. In plain terms, you get more power and a fancier interior, and you also get first-generation hardware with first-generation software. All-wheel drive is standard on every CX-90, which removes one thing to check on the window sticker.

Inline-six or plug-in hybrid

The inline-six is the one most people should buy. Car and Driver's CX-90 page lists a turbocharged 3.3-liter six with 280 hp and 332 lb-ft in regular trims and 340 hp and 369 lb-ft in S models, an eight-speed automatic, and an EPA rating of 25 mpg combined. Mazda's launch release describes that engine's M-Hybrid Boost as a mild-hybrid system, so it never plugs in. C/D's complaints are worth reading before a test drive: low-speed transmission shudders, a ride that gets sharp on broken pavement, and laggy paddles. Drive one in stop-and-go traffic, not just on the highway, and see if the shift quality bothers you.

The PHEV pairs a 2.5-liter four with an electric motor for 323 hp and 369 lb-ft and uses a 17.8-kWh battery, per Car and Driver's CX-90 Hybrid review. C/D quotes about 26 miles of EPA electric range (its 2024 test sheet shows 25) and a 3,500-pound tow rating with the tow package, versus up to 5,000 pounds on most inline-six trims. It is quicker and can do short commutes on electricity. Honestly, though, a plug-in that never gets plugged in is just a heavier gas SUV with extra parts, and the 2024 PHEV picked up its own drive-power recalls, which we list below.

Recalls we pulled by VIN year

We ran the NHTSA recalls API for the CX-90 this afternoon, October 15, 2026. Model year 2024 returned 11 campaigns, 2025 returned 2, and 2026 returned none. The 2024 list is the reason to slow down. 23V429000 covers steering and suspension bolts that may be missing or loose, which NHTSA says can let the intermediate shaft or front upper control arms detach. 24V022000 covers a steering worm gear assembly issue that can cause sudden loss of power assist. 24V349000 is a false automatic-braking event. 24V816000 covers an engine that may not restart after i-stop shuts it off.

PHEV owners have two more: 23V719000, where software can shut down the engine and motor, and 24V817000, where inverter software can cause a loss of drive power in EV mode. There are also camera software (23V718000), pedestrian-warning sound (23V553000), engine-light software (24V815000), a Dash Electrical Supply Unit campaign on 2024-2025 cars (24V814000), and a mild-hybrid fuel gauge fix (25V568000). Start with the NHTSA recalls feed for a 2024 CX-90, then use our Mazda recall check by VIN walkthrough on the exact car. A year list says what could apply. Only the VIN tells you what is still open.

What to look for on the history report

Because the oldest CX-90 is barely three model years old, most history reports are short, and short reports hide things easily. Look for repeat dealer visits in the first year, which on a 2024 often means recall or software work and is normal. A lot of visits with no recall codes is different, and worth asking about. Watch for rental or fleet use, a title that moved between states quickly, and any gap where the car disappears for months. Our guide to reading a CARFAX report walks through those lines. Decode the VIN with NHTSA's vPIC decoder or our Mazda VIN decoder notes so the powertrain matches the ad; a "PHEV" listing on an inline-six car happens more than it should.

Skip the seller's PDF. It can be months old or edited, and you have no way to tell from a screenshot, so pull your own. A CARFAX through us is about $5.50 as a guest or about $4.50 as a member, and a CARFAX plus AutoCheck bundle is about $6.75, against retail of roughly $39.99 to $44.99 as of mid October 2026; confirm at checkout. We are a licensed CARFAX and AutoCheck reseller and are not affiliated with CARFAX, AutoCheck, or Experian. CARFAX's own page explains what a full report covers.

Is it the right size?

If the third row is mostly for cargo, look at a two-row Mazda instead. Our used Mazda CX-50 buying guide covers a smaller, simpler option. C/D measured 16 cubic feet behind the CX-90's third row, so a full family road trip with luggage gets tight fast.
