Mercedes-Benz X253 (GLC-Class): A Comprehensive Guide
The Mercedes-Benz X253, marketed as the GLC-Class, represents Mercedes-Benz's foray into the compact luxury crossover SUV segment. Introduced in 2015 as a 2016 model, it replaced the GLK-Class, adopting Mercedes-Benz's revised nomenclature where "GL" signifies an SUV and "C" denotes its positioning relative to the C-Class sedan. The GLC aimed to blend the practicality and versatility of an SUV with the sophistication and driving dynamics expected from a Mercedes-Benz. It quickly became a strong contender in the competitive luxury SUV market, offering a wide range of engines, advanced technology, and elegant design.

Reliability & Common Issues
While generally reliable, the X253 GLC-Class, like any vehicle, has experienced certain common issues. Addressing these concerns proactively can help maintain its longevity and performance. Here's a breakdown of potential problems:
- 2.0L Turbocharged Engine (M274):
- Timing Chain Issues: Certain model years have been known to experience premature timing chain wear or failure, leading to engine noise, poor performance, and potential engine damage. Listen for rattling noises, especially on startup. Regular oil changes with the correct specification can mitigate this risk.
- High-Pressure Fuel Pump (HPFP): The HPFP can sometimes fail, causing starting problems, rough idling, and a loss of power.
- Turbocharger Problems: Although less common, turbocharger failures can occur. Symptoms include reduced power, excessive smoke, and unusual noises.
- 9G-TRONIC Transmission:
- Rough Shifting: Some owners have reported occasional rough or jerky shifting, especially at lower speeds. Software updates or transmission fluid changes can sometimes resolve this issue.
- Valve Body Issues: In rare cases, the valve body within the transmission may experience problems, leading to shifting difficulties or complete transmission failure.
- Electrical System:
- MBUX Infotainment System Glitches (Post-Facelift Models): The MBUX system, while advanced, can occasionally experience software glitches, freezing, or connectivity problems. Software updates are frequently released to address these issues.
- Sensor Malfunctions: Various sensors, such as those related to the driver-assistance systems or the parking sensors, can sometimes malfunction, triggering warning lights.
- Battery Drain: Leaving the vehicle unused for extended periods can sometimes lead to battery drain, particularly in models with numerous electronic features.
- Suspension:
- Air Suspension (Optional): Models equipped with air suspension may experience issues with the air struts leaking or the compressor failing over time, resulting in uneven ride height or a rough ride.
- Suspension Component Wear: Standard suspension components, such as bushings and ball joints, can wear out over time, leading to clunking noises and reduced handling performance.
- Other Concerns:
- Water Leaks: Some owners have reported water leaks, often from the sunroof or around the taillights. Inspect these areas for signs of moisture or water damage.
- Premature Brake Wear: Driving habits and road conditions can contribute to premature brake pad or rotor wear.
Preventative Maintenance is Key: Regular maintenance, including oil changes, fluid checks, and inspections, is crucial for preventing many of these issues and ensuring the long-term reliability of the GLC-Class. Be sure to adhere to Mercedes-Benz's recommended maintenance schedule.
Driving Experience
The Mercedes-Benz GLC-Class offers a comfortable and refined driving experience, blending luxury with practicality. However, specific aspects vary depending on the engine and options selected.
Pros:
- Comfortable Ride: The GLC-Class provides a smooth and composed ride, especially with the optional air suspension system.
- Refined Interior: The cabin is well-appointed with high-quality materials and a sophisticated design.
- Advanced Technology: The MBUX infotainment system (post-facelift models) offers a user-friendly and feature-rich experience.
- Wide Range of Engine Options: From the fuel-efficient GLC 300 to the high-performance AMG variants, there's an engine to suit various needs and preferences.
- Practicality: The GLC-Class offers ample cargo space and rear passenger room, making it a suitable choice for families.
- Available Safety Features: A comprehensive suite of driver-assistance systems enhances safety and convenience.
Cons:
- MBUX Complexity: While advanced, the MBUX system can be overwhelming for some users, requiring a learning curve.
- Repair Costs: Maintenance and repairs can be more expensive compared to non-luxury vehicles.
- Base Engine Performance: The GLC 300, while adequate, may feel underpowered for some drivers, especially when fully loaded.
- Optional Equipment Adds Up: The base models can feel sparsely equipped, and adding desired options can significantly increase the price.
Buying Advice
When considering a used Mercedes-Benz GLC-Class (X253), keep the following in mind:
- Model Year:
- Post-Facelift (2020-2022): These models offer the updated MBUX infotainment system, improved engine performance, and revised styling. They are generally a better choice if your budget allows.
- Pre-Facelift (2016-2019): These models represent a good value proposition if you're comfortable with the older infotainment system and styling. However, be vigilant about the potential timing chain issues in the 2.0L engine.
- Engine Choice:
- GLC 300: A good all-around choice for daily driving, but consider test-driving to ensure it meets your power requirements. Thoroughly inspect for timing chain issues.
- GLC 43 AMG: Offers significantly more performance and a sportier driving experience. Expect higher running costs.
- GLC 63 AMG: Delivers exhilarating performance, but is the most expensive to purchase and maintain.
- GLC 350e (Plug-in Hybrid): While offering some electric range, the hybrid system adds complexity and potential maintenance points.
- Maintenance History:
- Crucial! Obtain a complete service history to assess how well the vehicle has been maintained. Pay close attention to oil change intervals and any reported repairs.
- Pre-Purchase Inspection:
- Essential! Have a qualified Mercedes-Benz mechanic perform a thorough pre-purchase inspection to identify any potential problems. This is especially important for older models. Focus on engine timing chain (2.0T), transmission function, suspension components (especially air suspension if equipped), and electrical systems.
- Check for Recalls:
- Verify that all applicable recalls have been addressed.
- Air Suspension:
- If the vehicle is equipped with air suspension, carefully inspect the system for leaks or signs of compressor failure. Replacement costs can be significant.
- Negotiate Price:
- Factor in any identified issues during the inspection and negotiate the price accordingly. Research comparable models to determine a fair market value.
By carefully considering these factors and conducting thorough research, you can find a used Mercedes-Benz GLC-Class that meets your needs and provides a rewarding ownership experience.
