Citroën C5 II (RD/TD) (2008–2017) (2008 – 2017)

Reliability score : 7.2/10

The second-generation Citroën C5 (internal codes RD for the sedan, TD for the Tourer) was launched in 2008, marking a turning point for the brand in the executive car segment. Abandoning the bold style of its predecessor, it adopted a more classic and stately line, inspired by German sedans, while retaining Citroën's DNA with exceptional suspension comfort. It was available as a sedan and a wagon (Tourer). Its main technical characteristic lay in the choice between a classic metallic suspension (firmer) and the famous Hydractive III+ hydropneumatic suspension (available on higher trims and more powerful engines), offering unparalleled ride comfort and serene road holding. The C5 II underwent a minor facelift in 2010 (phase 2) with LED lights and new engines, followed by a second in 2012 (p

✅ Strengths

Exceptional suspension comfort (Hydractive III+)
Remarkable sound insulation
Quality of finish and interior materials
Generous interior space (especially in the Tourer)
Very safe road holding and serene road behavior
Very attractive price/performance ratio on the used market

⚠️ Weaknesses

High weight penalizing fuel consumption and performance of smaller engines
Large turning radius
Limited rear visibility on the sedan
Potentially high maintenance cost for V6 diesel engines and Hydractive suspension in case of breakdown
Imperfect reliability of 1.6 HDi and 1.6 THP

🎯 Verdict

The Citroën C5 II is an excellent executive car, offering first-class comfort and sound insulation, especially with the Hydractive III+ suspension. It's a car that ages well and offers an unbeatable quality/price ratio on the used market. For a worry-free purchase, prioritize the 2.0 HDi engines (140, 150, or 163 hp), which are the most reliable, versatile, and economical to use. They represent the best compromise for this car. The 2.2 HDi 204 is also an excellent option for those seeking more power. Be more cautious with the 1.6 HDi: it can be interesting for predominantly urban/suburban use if maintenance has been impeccable and you are prepared to maintain it rigorously. The 1.6 THP petrol versions should be considered with caution and a clear service history. The V6 HDi (2.7 and 3.0) engines offer exceptional driving pleasure but can incur very high maintenance costs in case of problems. They are reserved for enthusiasts with a substantial budget for preventive and curative maintenance. It is imperative to check the service history, especially for vehicles equipped with Hydractive suspension and diesel engines. A thorough road test is essential to ensure the proper functioning
