Toyota Yaris Cross I (MXPJ) (2021 – 2025)

Reliability score : 9.0/10

The Toyota Yaris Cross (first generation, codename MXPJ/MXPB for the TNGA version) is a B-segment urban SUV based on the TNGA-B platform, shared with the Yaris IV. Launched in 2021, it quickly established itself as a bestseller thanks to its adventurous design, compactness (4.18 m), and the efficiency of its powertrains. Although the European market overwhelmingly favors the hybrid (HSD) version, the Yaris Cross is also offered with a 100% naturally aspirated gasoline engine (M15A-FKS), which stands out for its mechanical simplicity and unparalleled reliability. A slight restyling (facelift) and a technological update (new multimedia system, digital gauges, revised sound insulation) occurred in early 2024, accompanied by the introduction of a more powerful hybrid version (130 hp). Overall

✅ Strengths

Exceptional mechanical reliability, particularly with the 1.5 naturally aspirated gasoline engine (no turbo, no complex DPF).
D-4S dual injection on the 1.5 gasoline engine prevents valve fouling (a common problem on pure direct injection engines).
Very controlled fuel consumption, even on the 100% gasoline version (around 5.5 to 6.0 L/100 km in mixed use).
Availability of all-wheel drive (AWD-i), rare in this segment.
Excellent resale value on the used car market.
Toyota Relax warranty (up to 10 years or 160,000 km if serviced within the network).

⚠️ Weaknesses

Imperfect sound insulation on pre-2024 models (wind and road noise on highways).
1.5 gasoline engine (M15A-FKS) noisy during strong accelerations (typical of 3-cylinders).
Very average rear passenger space and narrow rear access (limited door opening).
Quality of some interior plastics (hard and prone to scratches).
Multimedia system on 2021-2023 versions slow and dated (corrected in 2024).
Recurring weakness of the 12V auxiliary battery on hybrid versions with short, infrequent trips.

🎯 Verdict

The Toyota Yaris Cross is a pragmatic and extremely reassuring choice. While the hybrid version captures all the attention, the 100% gasoline version (1.5 VVT-i 125 hp) is a true gem of reliability for those who wish to keep their vehicle for the very long term. Devoid of a turbocharger and equipped with intelligent dual-mode injection, this M15A-FKS engine is immune to the costly breakdowns that plague its European competitors (PureTech, older TSI). Although it can be a bit noisy under load and the interior lacks refinement, its negligible running costs and its manufacturer's warranty, extendable to 10 years, make it one of the smartest purchases in the B-SUV segment.
