Reliability favors the KIA Sportage over the Mazda CX-50 by a clear margin, mostly on a much lower complaint rate per car sold. The Sportage also has nine model years of history, while the CX-50 has four. Its engine and cruise control reports are the serious catch.

How Do the Kia Sportage and Mazda CX-50 Generations Compare?

Most used Sportages a shopper sees will be fourth generation (QL), which ran 2017 to 2022 and got a facelift in 2020. The 2018 year in that run is among the weakest. The fifth generation (NQ5) began in 2023, and that first year is also a weak one. The CX-50 has one generation so far. It covered 2023 and 2024, and an update arrived for 2025. Its first year, 2023, is among its weakest. Any CX-50 you find is at most a few years old.

Verdict

The Kia Sportage is more reliable than the Mazda CX-50, scoring 75/100 vs 70/100.

A clear edge goes to the Sportage, and the deciding reason is the complaint rate. Owners filed about 5.3 complaints per 10,000 sold, against 27.4 for the CX-50, and the Sportage has nine model years behind that rate. The edge comes with a catch. The worst Sportage reports are severe, including engine replacement and cruise control surging. The CX-50 has only four model years, so its record is short.

What Are the Common Problems With the Kia Sportage and Mazda CX-50?

Serious failures dominate the Sportage reports: engines that run low on oil and then knock or lock up, cars that shut off while driving, and cruise control that sets itself to 110 mph. Fires appear in the engine and electrical reports. CX-50 complaints are milder. False automatic braking, a liftgate opening on a freeway on-ramp, dead batteries that lock the car, and failed front ball joints lead the list.

Its structure and power train complaints have none.

Who Should Buy the Kia Sportage vs the Mazda CX-50?

Pick the Sportage if you want the better overall record and a wider choice of model years. Its repair cost is low and its shop visits are rare. Skip 2018 and 2023, the two weakest years. Before you buy, get full oil change records, since owners say Kia denied engine claims over maintenance paperwork. Ask a dealer whether the car has had cruise control problems, and avoid using cruise until you know. Pick the CX-50 if you want a midsize SUV and can accept a short track record. Its complaints are less severe, but check the front suspension for clunks and ask about any false braking events. Avoid 2023 and 2025, its weakest years. Of the others, 2024 is the safer target. The 2026 model ranks well, but it is recent and has had little time to collect complaints. If you plan to tow, note the owner reports about the trailer harness and the 1000 lb limit without a brake controller.
