Mazda is the dark-horse reliability champion. The Skyactiv-G port-injected 2.5L is one of the most durable engines on the market, the 6AT automatic is a refined Aisin-style geared transmission (not a CVT), and Mazda has resisted shipping unproven turbo or DCT technology to mass market. CX-5 and Mazda3 routinely outperform Toyota and Honda on Consumer Reports surveys. Weak spots: Skyactiv-D diesel never made it to the US, and the new Skyactiv-X 2.5T has had carbon buildup complaints.
Consumer Reports has ranked Mazda the #1 most reliable brand in multiple recent years, beating even Toyota and Lexus. J.D. Power's dependability study places Mazda in the top tier.
Skyactiv-G + 6-speed Aisin. Few systemic issues. CR top pick multiple years.
New gen interior + drivetrain. Very low complaint rate.
Skyactiv 2.0L, manual or 6AT. Simple, light, durable.
2.5T inline-4 - mature; better than V6 alternatives.

Turbo oil starvation if oil change intervals slipped. Engine failure common.
Rust on rear wheel arches and clutch issues.
Skyactiv-X carbon buildup (2019-2021 CX-30/Mazda3), brake booster recall on CX-5 (2014-2017), and infotainment screen freezes pre-2019. Otherwise the brand has remarkably clean complaint data.
Average $462/year per RepairPal - in line with Honda. Resale is strong. Long-term cost of ownership beats most competitors.

Per Consumer Reports surveys in 2021 and 2023, yes - Mazda took the #1 spot. The advantage is small but real.
A Skyactiv-G CX-5 or Mazda3 will go 250K+ with timely oil changes. The 6-speed automatic is excellent.
No. Mazda has resisted CVTs entirely - they use a conventional 6-speed Aisin-style geared automatic in nearly all models.
Carbon buildup on intake valves after 50-70K miles, requiring walnut blasting. Affects 2019-2021 CX-30 and Mazda3.
The 2.5T (CX-9, Mazda3, CX-50) has held up well so far. The older DISI 2.3T (CX-7) was the problem child.
On reliability data, slightly. On dealer network and resale, Honda still wins.
