Peugeot 5008 (Gen 2) Common Problems & Reliability
The second-generation Peugeot 5008 (2017–2024) successfully transitioned from a traditional MPV to a more contemporary, stylish seven-seat SUV, garnering praise for its versatile cabin and distinctively upscale "i-Cockpit" interior design. While this generation marks a significant improvement in overall build quality over its predecessor, it is not without its mechanical and electrical complexities. A prospective owner must be prepared for the specific maintenance demands of its engine and emissions hardware. The primary mechanical concern is the 1.2 PureTech petrol engine, which utilizes a "wet belt" timing system that runs submerged in engine oil. The long-term reliability of this component is entirely dependent on adhering to stringent service intervals and using the precise oil viscosity specified by PSA. Failure to maintain these standards can result in belt degradation, where rubber particles clog the oil pump, potentially leading to catastrophic engine damage. It is critical to confirm that any used 5008 has a documented, complete service history from a Peugeot Main Dealer. Diesel-powered variants (BlueHDi) are fundamentally robust for high-mileage users, provided the AdBlue emissions control system is managed correctly. The internal pump and tank sensor assembly are known weak points, and failure typically requires an expensive, complete tank replacement. Furthermore, drivers of diesel 5008s should prioritize regular motorway journeys to ensure effective Diesel Particulate Filter (DPF) regeneration; frequent, short urban journeys can lead to premature clogging, which eventually demands costly intervention. Finally, while electrical issues are frequent, they typically manifest as non-catastrophic software glitches—such as infotainment freezing or sensor errors—rather than complete system failure. Many of these quirks are effectively resolved via dealership firmware updates. Potential buyers should comprehensively test all digital interfaces and request documentation confirming that all relevant software recalls have been addressed. While the 5008 Gen 2 is a highly capable family transport, it is a vehicle that rewards strict adherence to preventative maintenance schedules.

1.2 PureTech "Wet Belt" Degradation
The timing belt runs in oil and can degrade, shedding debris that blocks the oil pickup. This leads to oil starvation, vacuum pump failure, and a dangerous loss of braking assistance (Recall R/2020/331).
