Porsche Cayenne III (9YA) (2018 – 2025)

Reliability score : 8.0/10

The third-generation Porsche Cayenne (Type 9YA), launched in 2018 and heavily facelifted in 2023, is based on the Volkswagen Group's MLB Evo platform (shared with the Audi Q8, Bentley Bentayga, and Lamborghini Urus). This generation marks a historic turning point for the model with the definitive abandonment of diesel engines in favor of a highly advanced plug-in hybrid (PHEV) strategy. Available in classic and 'Coupé' body styles (since 2019), the Cayenne III stands out for its exceptional dynamic behavior for its weight, top-flight finish, and advanced technological integration. The 2023 facelift brought a new interior (inspired by the Taycan), revamped engines (the V8 makes its return on the S version), and higher-capacity hybrid batteries (25.9 kWh).

🎯 Verdict

The Porsche Cayenne III (9YA) is arguably the most dynamic and refined luxury SUV in its segment. The E-Hybrid versions, which account for the majority of sales in Europe, offer remarkable versatility, especially since the 2023 facelift that equips the vehicle with a 25.9 kWh battery providing genuine electric range. In terms of mechanical reliability, the V6 and V8 engines are robust (very low ADAC breakdown rate of 2.8). However, the record is tarnished by recurring electronic bugs (infotainment, ADAS, cameras) and an air suspension that, while high-performing, remains a long-term weak point (highlighted by the TÜV). The colossal weight of the hybrid versions also generates significant running costs (tires, brakes). It is a vehicle to BUY if you prioritize driving pleasure and benefit from a 'Porsche Approved' warranty, but to NEGOTIATE with caution on the used market outside the network, demanding a clear history and a high-voltage battery test.
