Mercedes GLA H247 (2020 – 2025)

Reliability score : 8.4/10

Mercedes-Benz GLA (H247) The second-generation Mercedes-Benz GLA (H247) represents a significant shift from its predecessor (X156). While the first generation was essentially a raised A-Class hatchback, the H247 adopts a true compact SUV silhouette, offering vastly improved interior space, headroom, and a higher seating position. Built on the MFA2 (Modular Front Architecture) platform, it shares its underpinnings with the A-Class (W177), B-Class (W247), and GLB (X247). The interior is dominated by the impressive MBUX (Mercedes-Benz User Experience) dual-screen infotainment system, setting a high standard for cabin technology in the premium compact segment. Focus on Diesel (OM654q): For high-mileage drivers, the GLA relies on the transverse version of Mercedes' excellent 2.0-liter diesel en

✅ Strengths

OM654q diesel engine is exceptionally efficient and refined
Vastly improved interior space and headroom compared to the previous generation
MBUX infotainment system is class-leading in graphics and voice control
High-quality interior materials and ambient lighting
Smooth and responsive 8G-DCT transmission (especially with diesel and 2.0L gas engines)
Comfortable ride quality, especially on standard suspension setups

⚠️ Weaknesses

High purchase price and expensive optional extras
1.33L gasoline engine (M282) sounds strained under heavy acceleration
Intrusive Lane Keeping Assist system (often requires manual deactivation)
Capacitive touch controls on the steering wheel (post-2023 facelift) are less intuitive than physical buttons
PHEV variant loses significant trunk space due to battery placement
Diesel models are unsuitable for strict city driving (DPF/EGR issues)

🎯 Verdict

Final Verdict The Mercedes-Benz GLA (H247) is a highly accomplished premium compact SUV that corrects almost all the flaws of its predecessor. It is spacious, technologically advanced, and comfortable. For Diesel Buyers: The GLA 200 d is the sweet spot of the entire range. The OM654q engine is a masterpiece of modern diesel engineering—quiet, punchy, and capable of returning outstanding fuel economy on the highway. However, it is strictly recommended for drivers doing high annual mileage with regular highway runs. If you buy this diesel for short city commutes, you will inevitably face expensive DPF, EGR, and AdBlue system failures. Always inspect the tandem pump for coolant leaks before purchasing a used model. For Urban/Mixed Buyers: If your driving is mostly urban, avoid the diesel. The GLA 200 (gasoline) or the GLA 250 e (PHEV, if you can charge at home) are much better suited to city life, despite the 1.33L engine being slightly less refined than the diesel.
