DS DS7 I (X74) (2017–2025) (2017 – 2025)

Reliability score : 6.5/10

The DS7, initially launched as the DS7 Crossback in 2017, is the first premium SUV from the DS Automobiles brand, positioned in the C-SUV segment. It embodies French expertise in luxury and technology, with a distinctive design, a refined interior, and remarkable suspension comfort (Active Scan Suspension). The first generation (internal code X74) underwent a significant facelift in 2022, dropping the 'Crossback' suffix to become simply 'DS7', and introducing new, more powerful plug-in hybrid powertrains. Overall, the DS7 offers a pleasant driving experience and a high level of finish, but its reliability can vary depending on the engine, particularly the early petrol versions and the AdBlue systems on diesel models.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The DS7 is an SUV that appeals with its style, comfort, and interior presentation. However, reliability is a point to consider carefully. 1.2 PureTech versions are to be avoided in the absence of a perfect service history and proof of preventive timing belt replacement. BlueHDi diesels are good choices for high-mileage drivers, provided you are vigilant about the AdBlue system. 1.6 PureTech versions are a balanced option for petrol, but require rigorous maintenance to prevent carbon buildup. E-Tense (PHEV) versions are promising in terms of performance and consumption (if recharged), but their technological complexity and market youth require careful monitoring. For a confident purchase, prioritize well-maintained models, ideally with a warranty, and opt for the 1.6 PureTech or 2.0 BlueHDi (pre-2020) engines or the E-Tense if your usage is suitable.
