Mercedes Classe A W177 (2018 – 2025)

Reliability score : 8.2/10

The Mercedes-Benz A-Class W177 (hatchback) and V177 (sedan) represent a massive technological leap over the previous generation. Introduced in 2018, it debuted the revolutionary MBUX infotainment system, setting a new benchmark for premium compact interiors. While it shares its MFA2 platform with other compact Mercedes models, it offers a highly refined driving experience. The diesel lineup is particularly noteworthy: early models utilized the Renault-derived 1.5L OM608, which was later replaced entirely by Mercedes' own highly efficient 2.0L OM654q. A mid-cycle facelift in late 2022 (Model Year 2023) brought mild-hybrid technology to petrol engines, updated MBUX software, and subtle exterior tweaks. Overall, it is a highly desirable premium hatchback, though early production years suffere

✅ Strengths

Class-leading MBUX infotainment system with excellent voice recognition
Exceptional fuel economy and refinement from the OM654q 2.0L diesel engines
High-quality interior design and ambient lighting
Wide range of engines catering to all needs (from economical diesels to hyper-hatches)
Comfortable ride quality, especially on models with adaptive suspension

⚠️ Weaknesses

Interior build quality issues on early models (creaks and rattles from the dashboard and door panels)
7G-DCT and 8G-DCT dual-clutch transmissions can be jerky at low speeds or in stop-and-go traffic
Expensive maintenance and repair costs, typical of Mercedes-Benz
AdBlue and NOx sensor vulnerabilities on diesel models
Severe cylinder head issues on early M260 2.0L petrol engines (2018-2020)

🎯 Verdict

The Mercedes-Benz A-Class W177 is a stunning premium compact car that excels in technology and design. If you are targeting a diesel, you are making a very smart choice: the later 2.0L OM654q (A 200 d / A 220 d) is one of the best diesel engines in its class, offering a superb blend of punchy performance and incredible fuel economy. The earlier 1.5L OM608 is also a solid, economical choice for tighter budgets. However, buyers should be cautious of early petrol models (specifically the 2.0L M260) due to severe cylinder head issues, and all buyers must accept that early production years (2018-2019) suffer from annoying interior rattles and MBUX software bugs. Aim for a 2020 or newer diesel model for the best ownership experience.
