Citroën C4 Cactus I facelift (2018 – 2022)

Reliability score : 4.2/10

The restyled first-generation Citroën C4 Cactus (Phase 2) marks a major turning point in the life of the model. Gone is the positioning as a quirky small crossover: Citroën repositioned it as a compact hatchback to compensate for the discontinuation of the C4 II. The famous 'Airbumps' are reduced to the bottom of the doors, the front fascia is toned down, and soundproofing is improved. Above all, it inaugurates the Citroën Advanced Comfort program in Europe with progressive hydraulic cushion (PHC) suspensions and high-density foam seats, offering exceptional ride comfort for the category. However, its reliability record is heavily tarnished by the design flaws of its engines (PureTech petrol and BlueHDi diesels), making buying it used particularly risky without a flawless maintenance histo

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The restyled Citroën C4 Cactus is a car full of intrinsic qualities: its comfort is royal and its running cost (excluding breakdowns) is very low. Unfortunately, it is powered by the worst engine blocks of the recent PSA era. Choosing a diesel (1.5 or 1.6 BlueHDi) exposes you to the costly whims of the AdBlue system, and the 1.5 adds the fatal risk of camshaft chain breakage. In petrol, the PureTech is a ticking time bomb. Our advice: AVOID in the majority of cases. If you absolutely insist on this model in diesel, look for a 1.6 BlueHDi 100 whose AdBlue tank has been recently replaced with an invoice, or a 1.5 BlueHDi whose timing system (including the 8mm chain) has been updated by a professional. Negotiate the price firmly to anticipate breakdowns.
