Mercedes GLA Problems: What To Know Before Buying
The Mercedes-Benz GLA is a compact luxury SUV that blends premium styling, smart technology, and daily practicality. It’s especially favored by city drivers looking for a higher seating position without the bulk of a larger SUV. However, like any vehicle, the GLA has a few known issues worth considering. If you’re planning to buy a used GLA — including the GLA 200, GLA 250, GLA 220d, or AMG GLA 35/45 — it’s helpful to understand the most common Mercedes GLA problems, particularly across the X156 (2014–2019) and H247 (2020–present) generations.
1. Dual-Clutch Transmission Issues
Most GLA models use a 7-speed or 8-speed dual-clutch automatic transmission. While generally smooth and fuel-efficient, it can cause some drivability concerns at lower speeds.
Common symptoms:
- Jerky or delayed shifts
- Hesitation in stop-start traffic
- Trouble engaging reverse gear
- Transmission fault codes
Make sure to check for transmission software updates and verify regular service intervals to help avoid future issues.
2. Infotainment System Glitches
The X156 features the COMAND system, while newer H247 models use the MBUX interface. Both systems are packed with tech but can occasionally experience faults.
Typical problems:
- Frozen or slow touchscreen
- Bluetooth pairing issues
- GPS navigation errors
- Malfunctioning voice controls
Most are software-related and fixable through system updates at a dealership.
3. Suspension and Ride Quality Complaints
The GLA has a sporty driving feel, but this comes at the cost of comfort for some drivers — especially in AMG-Line versions with larger wheels.
Potential issues:
- Stiff or bumpy ride on uneven roads
- Suspension noise or knocking
- Uneven tire wear
Check the condition of shocks, struts, and bushings during a test drive or inspection.
4. Electrical System Faults
The GLA includes advanced driver assistance systems, which can occasionally misbehave due to sensor or software errors.
Common complaints:
- Lane-keeping assist or blind-spot monitoring errors
- Inconsistent ADAS performance
- Random dashboard warning lights
- Problems with keyless entry or ignition
A diagnostic scan can help pinpoint faulty sensors or outdated software.
5. Oil Leaks in Older Models
Some early GLA engines, particularly in the X156 generation, may develop oil leaks from seals and gaskets.
Look out for:
- Oil spots beneath the car
- Oil level warnings on the dash
- Smell of burning oil under load
These issues are repairable but should be addressed quickly to avoid further damage.
6. Interior Trim and Fitment Issues
While the GLA cabin is generally well-built, some earlier models have shown minor trim problems.
Reported issues:
- Loose or creaky dashboard panels
- Worn buttons or peeling surfaces
- Rattling door panels
These are cosmetic but worth noting when inspecting a used vehicle.
Final Thoughts: Is the Mercedes GLA a Good Buy?
Yes — the Mercedes GLA offers a well-balanced package of comfort, performance, and luxury in a compact SUV. The second-generation GLA (H247) improves on space, tech, and overall refinement. With regular maintenance and proper care, the GLA is a smart choice for urban and suburban drivers.
Before you buy:
- Always inspect the vehicle thoroughly
