Mercedes GLC X253 (2015 – 2023)

Reliability score : 7.8/10

The Mercedes-Benz GLC (X253 Generation / C253 for the Coupé) succeeded the GLK in 2015. Based on the C-Class (W205) MRA platform, it marked a complete stylistic break from its predecessor, adopting fluid lines and a luxurious interior. Becoming the brand's global best-seller, it benefited from a major restyling (facelift) in 2019, introducing the MBUX infotainment system, new driving aids, and a complete overhaul of its engine range (transition from M274/OM651 blocks to M264/OM654 with 48V mild hybridization). Although generally well-designed, the first model years (2015-2018) require particular vigilance, especially regarding the M274 petrol engines and the air suspension.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The Mercedes GLC X253 is an extremely well-rounded premium SUV, offering undeniable comfort and status. If you are targeting a petrol engine, absolutely prioritize a facelifted (post-2019) model equipped with the M264 engine (GLC 200 or 300). Pre-2019 petrol models (M274) present a significant mechanical risk (piston pin) which can be very expensive. For sportiness enthusiasts, the GLC 43 AMG (V6) is an excellent compromise, offering superior reliability to the 63 AMG's V8 while maintaining (relatively) reasonable running costs. Avoid air suspension if you are buying a high-mileage model without a warranty.
