The third-generation Citroën C4 (internal code C41) marks a radical departure from traditional compact hatchbacks, adopting a bold crossover-coupe silhouette. Built on the Stellantis CMP platform, it heavily prioritizes ride quality, featuring Citroën's 'Advanced Comfort' suspension with progressive hydraulic cushions. While this report focuses primarily on the 1.5 BlueHDi diesel variants—which offer excellent fuel economy for high-mileage drivers but come with specific reliability caveats—the C4 III is a multi-energy vehicle. Its lineup spans from the controversial 1.2 PureTech petrols to the newly introduced 48V Mild-Hybrid and the fully electric ë-C4. Overall, it is a highly comfortable and distinctive family car, but buyers must be extremely vigilant regarding engine maintenance histor
The Citroën C4 III is an exceptionally comfortable cruiser that excels on long journeys. However, buying the 1.5 BlueHDi diesel requires extreme caution. While it is a fantastic engine in terms of performance and efficiency, the catastrophic risk associated with the 8mm camshaft chain and the fragile AdBlue system makes it a risky used purchase unless you have documented proof that the 13mm chain upgrade has been performed and the AdBlue tank has been recently replaced. If you must buy the diesel, seek a late 2023+ model. Otherwise, the newer 1.2 Hybrid 48V (with the timing chain) or the fully electric ë-C4 are much safer, more reliable long-term investments.
