Citroën C4 II (B7) (2010 – 2018)

Reliability score : 5.5/10

The Citroën C4 Generation II (Internal code: B7) marked a significant departure from its predecessor. Abandoning the quirky fixed-hub steering wheel and polarizing styling of the first generation, Citroën opted for a more conservative, premium-oriented approach. It shares its PF2 platform with the Peugeot 308 I. The C4 II is renowned for its outstanding ride comfort, excellent sound insulation, and a class-leading boot capacity (408 liters). A mid-life facelift in 2015 brought updated Euro 6 engines (PureTech and BlueHDi), revised headlights with LED daytime running lights, and a 7-inch touchscreen infotainment system. While it excels as a comfortable cruiser, its reliability record is highly dependent on the chosen powertrain, with significant known issues on certain petrol and modern die

✅ Strengths

Class-leading ride comfort and suspension compliance
Excellent sound insulation for a C-segment car
Large and practical boot (408 liters)
High-quality interior materials compared to the previous generation
Extremely frugal and pleasant HDi / e-HDi diesel engines
Good rust resistance and overall bodywork durability

⚠️ Weaknesses

Catastrophic reliability of the 1.2 PureTech wet timing belt
Notorious timing chain and oil consumption issues on 1.6 THP
Expensive and frequent AdBlue tank failures on BlueHDi models
BMP6 / ETG6 automated manual gearboxes are jerky, slow, and prone to wear
Uninspiring driving dynamics (heavy steering, body roll)
Outdated and sometimes glitchy infotainment system (SMEG+)

🎯 Verdict

The Citroën C4 II is a comfortable, practical, and unassuming hatchback that makes an excellent long-distance cruiser. However, its reliability is a minefield depending on the engine. Avoid the 1.6 THP and the 1.2 PureTech unless you have absolute proof of recent, comprehensive preventative maintenance (new belt/chain, clean oil strainer). Avoid the BMP6/ETG6 automated manual gearbox due to its poor driving experience and reliability. The sweet spot of the range is the 1.6 e-HDi (110/115 hp) or the 2.0 HDi 150 hp paired with a manual gearbox or the traditional EAT6 automatic. If you must buy a petrol, look for a late-model PureTech with the updated belt and a flawless service record, but negotiate the price accordingly.
