Reliability score : 7.5/10

The Peugeot Partner III, also known by its internal code K9, is the third generation of the lion brand's leisure activity vehicle/light commercial vehicle, launched in 2018.

🎯 Verdict

The Peugeot Partner III (K9) is a versatile and modern vehicle, offering an excellent compromise between utility and family use. Its road handling is among the best in its category. For gasoline engines (1.2 PureTech): This is a relevant choice for predominantly urban and peri-urban use. However, the reliability of the wet timing belt is a major drawback. A purchase is NEGOTIATE if the service history is impeccable, if the belt has been recently replaced according to recommendations, and if the price reflects this potential risk. Rigorous monitoring is essential. For diesel engines (1.5 BlueHDi): Ideal for high-mileage drivers and professionals. Fuel efficiency and torque are assets. The AdBlue system remains a point of vigilance. A purchase is BUY if the vehicle has been well maintained, the AdBlue system functions without alerts, and recalls have been performed. For the electric version (e-Partner): This is an excellent choice for urban use and deliveries in low-emission zones. Mechanical reliability is high. A purchase is BUY if the range meets your daily needs and charging access is easy. In summary, the Partner III is a good vehicle, but it requires particular vigilance regard
