Mercedes GLC W254 (2022 – Présent)

Reliability score : 8.2/10

Mercedes-Benz GLC (Generation W254 / X254) The second-generation Mercedes-Benz GLC (internally designated X254 for the SUV and C254 for the Coupe) was introduced for the 2023 model year. Riding on the MRA2 platform shared with the W206 C-Class, it represents a significant technological leap over its predecessor. Positioning & Engineering: The W254 GLC is positioned as a premium mid-size luxury SUV. The most controversial yet forward-looking engineering decision was the complete elimination of 6- and 8-cylinder engines. Every single powertrain is now a 2.0L 4-cylinder (or 3.0L diesel in late European models) paired with electrification—either as a 48V Mild-Hybrid (MHEV) with an Integrated Starter-Generator (ISG) or as a Plug-in Hybrid (PHEV) boasting a massive 31.2 kWh battery.

✅ Strengths

Class-leading ride comfort, especially when equipped with the optional AIRMATIC air suspension and rear-axle steering.
Exceptional electric range for PHEV models (~100 km WLTP), effectively making it an EV for daily use.
Highly advanced MBUX infotainment system with excellent voice recognition and augmented reality navigation.
Superb cabin insulation; acoustic glass makes it one of the quietest SUVs in its segment.
Standard 4MATIC all-wheel drive across the entire range.

⚠️ Weaknesses

Complete loss of 6-cylinder engines in non-diesel models; the 4-cylinder AMGs lack the emotional soundtrack of previous generations.
Capacitive touch controls on the steering wheel are frustrating to use and prone to accidental inputs.
PHEV models suffer from a raised boot floor, significantly reducing cargo capacity compared to MHEV models.
High purchase price and expensive optional extras.
Over-reliance on screen-based controls for basic functions like climate control.

🎯 Verdict

Final Verdict The W254 Mercedes-Benz GLC is a technological tour de force and arguably the most luxurious and comfortable vehicle in the compact/mid-size premium SUV segment. If you are looking at the petrol variants (GLC 300), the M254 engine is mechanically sound, offering a great blend of performance and efficiency. However, this generation is defined by its extreme electronic complexity. The 48V mild-hybrid system and the massive MBUX interface have suffered from early-production software bugs and minor recalls. Buying Advice: If buying a 2023 or 2024 model, ensure all software updates and recalls (especially the fuel pump and 48V ground cable) have been performed by a certified Mercedes-Benz dealer. The PHEV models (GLC 300e/400e) are brilliant if you can utilize the 100km EV range daily, but avoid them if you rarely charge, as you will just be hauling around 400kg of dead weight. Avoid the 4-cylinder AMG models unless you are leasing, as their long-term reliability remains unproven and highly complex.
