The Mercedes-Benz GLC (X254), launched in 2022, represents the latest iteration of the luxury automaker's highly popular mid-sized SUV. Known for its upscale features, advanced technology, and strong performance, the GLC has become a go-to option for those seeking both luxury and practicality. However, like any vehicle, the GLC (X254) isn't without its issues. As this model is still relatively new, understanding its potential problems, along with how to ensure a smart purchase and manage ownership costs, is crucial for prospective buyers. In this article, we will discuss the common problems reported with the GLC (X254), what to look for when buying, the ownership costs, and provide a few alternative models worth considering.
Common Problems of the MERCEDES-BENZ GLC (X254) 2022-Present
1. Infotainment and Software Glitches
One of the more frequently reported issues with the 2022-present GLC models revolves around the MBUX infotainment system. Although the system is highly praised for its sleek interface, voice recognition, and advanced features, it has occasionally been prone to software glitches and frozen screens.
Common Issues:
- Screen freezes or unresponsiveness: Some owners have noticed that the central touchscreen or display can occasionally freeze, particularly after an update or when certain apps are being used.
- Connectivity issues: Problems with Bluetooth pairing or Apple CarPlay/Android Auto connectivity have also been noted. Sometimes, these systems may fail to sync or disconnect intermittently.
- Voice command malfunctions: The voice-activated system that’s part of the MBUX setup has been reported to be slow or inaccurate at times, especially when interpreting commands for navigation or media.
What to Look For:
- Check the responsiveness of the screen: During a test drive, interact with the infotainment system. Look for any delays in touch responses or instances where the screen becomes unresponsive.
- Test connectivity: Ensure that your smartphone can connect seamlessly via Bluetooth or Apple CarPlay/Android Auto. Disconnect and reconnect to see if any glitches occur.
- Voice command test: Use voice commands for navigation or media control to verify that the system responds quickly and accurately.
2. Suspension and Ride Comfort
While the GLC (X254) is renowned for its smooth and comfortable ride, some owners have reported issues with the air suspension system, particularly in models with the Air Body Control option. These problems generally manifest in a bumpy or harsh ride, especially when driving over uneven surfaces.
Common Suspension Problems:
- Air suspension leaks: The air suspension system, although advanced, can develop leaks over time, especially if the car is driven extensively on rough terrain. This results in a lower ride height and diminished ride comfort.
- Suspension failures: Some owners have reported early failure of suspension components, especially if the vehicle has high mileage or has been subject to heavy use, such as frequent off-road driving.
What to Look For:
- Test the suspension: During the test drive, pay close attention to how the car handles bumps and uneven surfaces. A bouncy or unstable ride could indicate air suspension issues or wear in traditional suspension components.
- Check for unusual noises: Listen for clunking, rattling, or popping sounds from the suspension, which may suggest issues with suspension joints or shock absorbers.
- Check the ride height: If the GLC is equipped with Air Body Control, look for any irregularities in ride height or uneven lowering of the vehicle.
3. Brake System Issues
The brake system of the GLC (X254) has been designed for optimal performance, but a few owners have reported premature brake pad wear and brake fluid leaks in certain models. These issues are typically more prevalent in vehicles that experience heavy braking (such as in urban driving environments or mountainous terrain) or higher mileage.
Common Brake System Problems:
- Squeaking or grinding noises: Premature brake pad wear can lead to squeaking or grinding sounds, indicating that the pads need to be replaced sooner than expected.
- Brake fluid leaks: Some models have experienced issues with brake fluid leaks, often around the brake calipers or master cylinder. This can compromise braking efficiency and may require costly repairs if not addressed promptly.
What to Look For:
- Test the brakes during your test drive: Listen for any abnormal noises when applying the brakes, such as squeaks or grinding sounds. A smooth and quiet braking experience is what you should expect.
- Look for signs of brake fluid leaks: Visually inspect the brake components, including the calipers and lines, for any signs of fluid leaks.
- Check the brake pads: If buying a used GLC, confirm the age and condition of the brake pads. If they’re worn down, plan for their replacement.
4. Engine Performance and Reliability
The GLC (X254) offers a variety of engine options, from the fuel-efficient 4-cylinder engines to the more powerful V6s and hybrids. However, some owners have reported turbocharger issues in the 4-cylinder models, particularly with the M264 engine. These problems are typically related to poor turbocharger performance, which can lead to a noticeable loss in acceleration or power.
Common Engine Problems:
- Turbocharger failure: This can lead to a loss of engine power, delayed acceleration, or a noticeable whistling noise from the turbo unit. Turbo failures are often caused by oil starvation or overheating.
- Fuel injector problems: A few owners have also reported issues with fuel injectors, resulting in rough idling, poor fuel economy, or misfires.
What to Look For:
- Test acceleration and power: During a test drive, check how quickly the GLC accelerates, especially during rapid acceleration or highway merges. Any noticeable hesitation or lack of power could point to turbocharger or fuel system issues.
- Listen for strange noises: A loud whistling or whining noise under acceleration could indicate a turbocharger issue.
- Monitor engine behavior: Pay attention to engine smoothness. Rough idling or irregular power delivery could suggest issues with the fuel injectors.
5. Climate Control and Air Conditioning
The GLC (X254) is equipped with a sophisticated dual-zone climate control system and an advanced air conditioning setup. While the system generally works well, some owners have reported issues with weak airflow, temperature inconsistencies, or coolant leaks in the AC system.
Common Issues:
- Weak airflow: Sometimes, despite the system being set to a high fan speed, airflow from the vents may feel insufficient, making it hard to cool the cabin effectively.
- Temperature regulation issues: Some owners have mentioned that the temperature can fluctuate unexpectedly, either blowing cold air when heat is expected or vice versa.
What to Look For:
- Test the climate control: During the test drive, run the air conditioning and heating system through all its modes. Ensure the temperature matches your settings, and the airflow is adequate.
- Check for unusual smells: A musty smell can sometimes indicate mold in the vents, which may suggest that the air conditioning system has a leak or condensation problem.
- Listen for compressor sounds: Strange noises from the air conditioning system may indicate a problem with the compressor or refrigerant.
What to Look for When Buying a MERCEDES-BENZ GLC (X254) 2022-Present
The 2022 GLC (X254) is still a relatively new car, so it’s important to be diligent when inspecting a used example. Here’s a checklist for potential buyers:
- Check the Service History: Ensure that the vehicle has undergone regular maintenance at authorized service centers. Mercedes-Benz recommends specific maintenance intervals, and any missed appointments could signal future issues.
- Inspect the Exterior and Interior for Wear: Even though the GLC is a premium vehicle, it's important to check for any scratches, dents, or wear inside the cabin. Ensure the materials are intact and that there is no excessive wear on high-use areas like the seats or steering wheel.
- Test the Infotainment System: With the MBUX system being a major feature, ensure that it works seamlessly. During a test drive, interact with the infotainment system to ensure it’s functioning correctly.
- Check for Recalls: Verify if the vehicle has been subject to any recalls and whether the necessary repairs were completed. You can do this by checking the vehicle’s VIN on Mercedes-Benz's official website.
How Expensive is It to Own a MERCEDES-BENZ GLC (X254)?
