Peugeot 408 II (2022–2025) (2022 – 2025)

Reliability score : 7.0/10

The second-generation Peugeot 408, launched in 2022, marks the lion brand's entry into the 'fastback' or 'crossover coupe' segment. Based on the EMP2 V3 platform, shared with the 308 III and Citroën C5 X, it positions itself between the 308 sedan and the 3008 SUV, offering a bold design and generous interior space. Its distinctive style and modern interior (i-Cockpit) are major assets. In terms of reliability, being a very recent model, long-term feedback is still limited. However, it relies on powertrains already known within the Stellantis group, whose reliability varies depending on the engine. The overall reliability score should therefore be considered with caution, particularly for the 1.2 PureTech gasoline engine, despite the announced improvements.

✅ Strengths

Bold and distinctive design
Suspension comfort and sound insulation
Generous rear passenger space
Modern onboard technology (i-Cockpit, driving aids)
Efficiency of plug-in hybrid versions (if regularly recharged)

⚠️ Weaknesses

Limited rear visibility due to the sloped rear window
Limited engine range (no diesel)
Historical reliability of the 1.2 PureTech (even if improved, caution is advised)
High price of plug-in hybrid versions
Decent boot volume but access sometimes less practical than an SUV

🎯 Verdict

The Peugeot 408 II is a bold and attractive proposition in the fastback crossover market. Its design, comfort, and technology are undeniable. However, as an expert, I must temper enthusiasm with caution, particularly regarding the long-term reliability of its powertrains. * For the 1.2 PureTech 130: Despite the improvements announced by Peugeot for post-2022 models, the history of this engine necessitates increased vigilance. If you opt for this version, ensure an impeccable service history and be prepared for rigorous monitoring of the timing belt. It is an acceptable choice for predominantly urban and suburban use, but with residual risk. * For the Plug-in Hybrid versions (180/225 hp): They represent the best compromise in terms of performance and efficiency, provided regular recharging is possible. The complexity of the hybrid system is the main long-term question mark, but the 1.6 PureTech internal combustion engine is generally more reliable than the 1.2. This is the most relevant choice for mixed use and daily electric commutes. In summary, the 408 is a pleasant car to live with, but its young age on the market and the history of certain powertrains call for caution. Prioriti
