Mercedes-Benz GLA-Class (H247) Comprehensive Guide
The Mercedes-Benz GLA-Class is a subcompact luxury crossover SUV, offering a blend of Mercedes-Benz refinement, technology, and practicality in a smaller, more affordable package. It appeals to buyers seeking a premium experience without the bulk of larger SUVs. This guide focuses specifically on the H247 generation, released in 2020.
1. Introduction: The Second Generation GLA
The GLA-Class was introduced to fill a gap in Mercedes-Benz's lineup for a smaller, more youthful SUV. The second generation, designated H247, represents a significant step forward from its predecessor. It boasts enhanced technology, increased interior space, improved driving dynamics, and a more sophisticated design, bringing it more in line with other modern Mercedes-Benz vehicles.
2. Generations: H247 (2020-Present)
This guide primarily addresses the H247 generation. However, it's important to understand its place in the GLA's lineage.
- H247 (2020-Present): The second generation GLA, featuring a completely new design, updated technology, and improved performance. Key improvements include:
- Increased wheelbase and overall length, resulting in more interior space, particularly for rear passengers.
- Updated MBUX infotainment system with advanced voice control and augmented reality navigation.
- More powerful and efficient engine options.
- Enhanced safety features, including advanced driver-assistance systems.
- Refined suspension and handling for a more comfortable and engaging driving experience.
- Improved styling, with a more mature and sophisticated appearance.
3. Reliability & Common Issues (H247)
While the H247 GLA is generally considered a reliable vehicle, like all cars, it has some potential issues to be aware of. It's crucial to remember that reliability can vary depending on maintenance history, driving habits, and specific model year.
Engine and Transmission:
- Engine Oil Consumption: Some early H247 models have been reported to experience higher-than-normal oil consumption. This is more common in turbocharged engines. Regular oil level checks are essential.
- Turbocharger Issues: Turbocharger failures can occur, although they are not widespread. Listen for unusual whistling or whining sounds from the engine, especially under acceleration.
- 8-Speed Dual-Clutch Transmission (DCT): The 8-speed DCT can occasionally exhibit jerky shifting or hesitation, especially at low speeds. A software update may resolve this issue, but in some cases, clutch wear or other mechanical problems might be the culprit. Check for smooth and responsive shifting during test drives.
Electrical Systems:
- MBUX System Glitches: The MBUX infotainment system, while advanced, can be prone to occasional glitches, such as freezing, lag, or connectivity issues. Software updates are crucial to keeping the system running smoothly. Ensure the system is functioning correctly during a pre-purchase inspection.
- Sensor Malfunctions: The GLA relies on numerous sensors for its driver-assistance features. Malfunctions in these sensors (e.g., parking sensors, blind-spot monitoring sensors) can occur, leading to error messages or system failures.
- Battery Issues: Modern cars with complex electronics can be sensitive to battery health. Ensure the battery is in good condition, especially in older H247 models.
Other Potential Issues:
- Suspension Noises: Listen for creaking or clunking sounds from the suspension, especially over bumps. This could indicate worn bushings, ball joints, or other suspension components.
- Water Leaks: Check the cabin for signs of water leaks, particularly around the sunroof (if equipped) and door seals.
Preventive Maintenance: Regular maintenance, including oil changes, filter replacements, and fluid flushes, is crucial for minimizing the risk of problems. Following the manufacturer's recommended service schedule is highly recommended.
Pre-Purchase Inspection: Before purchasing a used H247 GLA, a thorough inspection by a qualified mechanic is highly recommended. This will help identify any potential issues and provide valuable insights into the vehicle's condition.
4. Driving Experience
The H247 GLA offers a comfortable and engaging driving experience, balancing practicality with a touch of luxury. It's a good option for those who want a sporty feeling in a smaller package.
Pros:
- Comfortable Ride: The suspension provides a comfortable ride, absorbing bumps and road imperfections effectively.
- Agile Handling: The GLA handles well for a crossover SUV, with responsive steering and good body control.
- Refined Interior: The interior is well-appointed with high-quality materials and a modern design.
- Advanced Technology: The MBUX infotainment system and driver-assistance features are impressive and user-friendly.
- Fuel Efficiency: The engines offer a good balance of performance and fuel efficiency.
Cons:
- Rear Seat Space: While improved over the previous generation, rear seat space can still be tight for taller adults on longer journeys.
- Road Noise: Some road noise can be noticeable at higher speeds, especially on rough road surfaces.
- Complex Technology: The advanced technology can be overwhelming for some users and can require a learning curve.
- Optional Extras Add Up: The base models can feel a bit sparsely equipped, and the price can quickly escalate with optional extras.
5. Buying Advice
When considering a used H247 GLA, keep the following in mind:
Years to Look For:
Generally, newer model years (2022 onwards) benefit from any running changes and software updates addressing early issues. However, a well-maintained 2020 or 2021 model can also be a good value if it has a clean service history and has been properly cared for.
- 2022+ Models: These are generally preferable as they've likely had more software updates and potentially minor component revisions.
Years to Potentially Avoid/Be Cautious Of:
- Early 2020 Models: Pay close attention to engine oil consumption and transmission performance in these models. A thorough pre-purchase inspection is a must. Ensure all recalls have been addressed.
Key Considerations:
- Service History: A complete and documented service history is crucial. Pay attention to oil change intervals and other maintenance records.
- Trim Level: Consider the trim level and optional features that are important to you. The AMG Line package adds a sporty appearance and some performance enhancements.
- MBUX System: Test the MBUX system thoroughly to ensure it is functioning correctly and that you are comfortable using it.
- Test Drive: Take the GLA for an extended test drive, paying attention to engine performance, transmission smoothness, and suspension comfort.
- Pre-Purchase Inspection: A pre-purchase inspection by a qualified Mercedes-Benz mechanic is essential to identify any potential issues before you buy. Ask them specifically to check for oil leaks, turbocharger health, and transmission performance.
By considering these factors, you can increase your chances of finding a reliable and enjoyable H247 GLA-Class that meets your needs and budget.
