Citroën C4 III (2020 – 2025)

Reliability score : 6.2/10

The third-generation Citroën C4 (C4 III) represents a radical departure from its predecessors, abandoning the traditional compact hatchback silhouette for a bold, high-riding crossover-coupe design. Built on the Stellantis CMP (Common Modular Platform), it shares its underpinnings with the Peugeot 208/2008 but is stretched to fit the C-segment. Its primary selling point is the 'Citroën Advanced Comfort' program, featuring progressive hydraulic cushion suspension and high-density foam seats, making it one of the most comfortable cars in its class. While this sheet focuses primarily on the petrol (PureTech) variants, the C4 is a multi-energy vehicle, offering diesel (BlueHDi) and fully electric (ë-C4) powertrains. A mild-hybrid (MHEV) petrol version with a heavily revised engine architecture

✅ Strengths

Class-leading ride comfort thanks to Progressive Hydraulic Cushions.
Distinctive, polarizing design that stands out in the C-segment.
Ergonomic interior with physical climate controls (a fix from previous Citroën models).
Good passenger space and practical storage solutions (e.g., tablet holder).
Introduction of the much more reliable 1.2 Hybrid 136 with a timing chain (2024+).

⚠️ Weaknesses

The 1.2 PureTech (non-hybrid) engines suffer from severe reputation and actual reliability issues regarding the wet timing belt.
Infotainment system is somewhat sluggish and visually dated compared to rivals.
Sloping roofline compromises rear headroom for taller passengers and limits trunk practicality.
Handling is tuned entirely for comfort; significant body roll and vague steering.
Interior plastics in the lower cabin feel cheap and scratch easily.

🎯 Verdict

The Citroën C4 III is an exceptionally comfortable and uniquely styled crossover-hatchback. However, buying one requires careful powertrain selection. Avoid the standard 1.2 PureTech (100/130/155 hp) models unless they are heavily discounted, have a flawless, documented service history, and you are prepared for potential timing belt/oil consumption issues. If you want petrol, stretch your budget to the 2024+ 1.2 Hybrid 136, which uses a much more reliable timing chain. The ë-C4 is a solid, comfortable electric commuter, while the 1.5 BlueHDi is strictly for high-mileage drivers who understand the risks of modern diesel emissions systems.
