Mercedes GLC Problems

Since its debut in 2015, the Mercedes-Benz GLC has adorned the roads with its luxurious demeanor, yet beneath its opulence lies a narrative of recurrent issues that have cropped up among various model years.

Mercedes GLC Problems

1. Engine Woes: Positive Crankcase Ventilation Valve Failure

One prevalent issue flagged by the NHTSA revolves around engine-related complications, primarily tied to a malfunctioning Positive Crankcase Ventilation (PCV) valve.

Owners, notably from the 2016 to 2019 models, have reported engine failure risks due to faulty PCV valves. Repair costs outside warranty soar above $1500, leaving many disconcerted.

2. Rough Ride from Run-Flat Tires

The factory-installed run-flat tires, while promising extended drive after punctures, have spurred complaints about a harsh ride quality.

Owners with 20 or 21-inch wheels find the tires’ stiff sidewalls exacerbate the discomfort, particularly on uneven roads and potholes.

Some suggest slightly deflating the tires for relief or switching to regular tires, albeit at the cost of a spare tire.

3. Brake Squeal

Early GLC models faced excessive brake noise issues, notably squealing during reversing or braking. While cold weather exacerbated the problem, it persisted even in moderate temperatures, proving bothersome for many owners.

Mercedes-Benz addressed this with brake pad updates for newer models, though aftermarket options also offer solutions.

4. Shuddering or Crabbing While Turning

Instances of ‘crabbing’ or tire skipping during full-lock turns have plagued right-hand drive GLCs, mainly due to stiffer summer tires in colder weather.

Mercedes-Benz attempted a fix by updating steering knuckles for non-AMG variants. Alternatively, switching to all-season tires provides a more cost-effective solution.

5. Constant Vibrations from Steering Wheel

Steering wheel vibrations over rough roads or bumps have distressed numerous GLC owners. While initially attributed to mechanical issues, Mercedes-Benz acknowledged an electric power steering software update in 2020 as a resolution.

Rapidly changing the car’s speed might temporarily alleviate the vibration.

6. Jerky Transmission

Some GLCs exhibit jerky transmission behavior, causing discomfort during deceleration or acceleration, more noticeable in ‘Sport’ modes.

Mercedes-Benz released a software update to address this in late 2020, enhancing transmission performance, although some owners reported a perceived loss of responsiveness post-update.

7. Noisy and Stuttering Wipers

Early GLCs experienced wiper-related noise and stuttering issues, predominantly in the 2016 to 2018 models. Over time, softer wiper blades and occasional replacements improved the situation.

Mercedes-Benz issued a TSB instructing dealers to clean windshields thoroughly and replace wiper blades to mitigate the problem.

In light of these concerns, Mercedes-Benz has taken steps to rectify several issues through software updates, parts replacement, and official statements. While these problems have been reported, not all GLC owners face them, and proactive maintenance may mitigate their impact.

As Mercedes-Benz continues to enhance the GLC, addressing reliability concerns remains integral to its commitment to customer satisfaction.

These insights provide a comprehensive view of potential issues faced by Mercedes GLC owners.
