Peugeot 5008 III (P54) (2024 – Présent)

Reliability score : 7.5/10

Peugeot 5008 III (STLA Medium Platform) The third-generation Peugeot 5008 marks a radical shift for the French brand's flagship 7-seater SUV. Built on the new Stellantis STLA Medium platform, it grows in size to offer more interior space and adopts a much more angular, aerodynamic, and tech-heavy design, featuring the new 'Panoramic i-Cockpit'. CRITICAL NOTE REGARDING DIESEL: You requested a focus on the diesel powertrain. However, Peugeot has officially and permanently discontinued all diesel engines (BlueHDi) for the 5008 Generation III across all markets. The era of the 1.5 and 2.0 BlueHDi is over for this model. Buyers who traditionally relied on diesel for high mileage, heavy loads, or towing are now directed by Peugeot towards two electrified alternatives: the 1.2 Hybrid 136 (MHEV) f

✅ Strengths

Complete elimination of the unreliable 1.2 PureTech wet-belt engine (replaced by a timing chain).
Excellent interior space with a genuine 7-seat configuration.
Stunning Panoramic i-Cockpit with high-quality materials.
Impressive electric range on the E-5008 Long Range (up to 660 km WLTP).
Comfortable ride quality despite the heavy weight.

⚠️ Weaknesses

NO DIESEL OPTION: A major drawback for heavy towers and extreme high-mileage drivers.
Significant weight increase (the EV versions weigh over 2.2 tons), impacting agility and tire wear.
Unproven long-term reliability of the brand new STLA Medium platform and Punch Powertrain gearboxes.
High purchase price, especially for PHEV and Long Range EV variants.
Early software bugs in the infotainment and ADAS systems.

🎯 Verdict

The Peugeot 5008 III is a technological leap forward, but it requires a shift in mindset for traditional buyers. The death of the diesel engine in this model is a significant event. If you absolutely need a diesel for heavy towing or driving 40,000+ km a year on highways, you must look at competitors like the Skoda Kodiaq or buy a used 5008 II 1.5 BlueHDi. However, as a replacement, the new 1.2 Hybrid 136 MHEV is highly promising. By finally ditching the disastrous wet belt for a timing chain, Peugeot has theoretically solved its biggest reliability nightmare. The PHEV 195 serves as the high-power alternative, though it is complex and expensive. Because the STLA Medium platform, the e-DCS gearboxes, and the software architecture are entirely new, long-term reliability is currently unproven. We recommend a cautious approach: lease rather than buy outright, or wait for the 2025 production year to ensure early teething issues are resolved.
