Common Mercedes GLC Reliability Issues

If you own a Mercedes GLC, you may have experienced some of the common reliability issues that many GLC owners face. In this section, we will discuss some of these issues and provide you with some helpful information.

Engine Issues

One of the most common issues that GLC owners face is engine problems. Some GLC models, such as the GLC 250 and GLC 300, have been known to experience engine misfires, which can cause the engine to run rough or stall.

In addition, some GLC models have reported oil leaks, which can cause serious engine damage if not addressed promptly.

Air Suspension Issues

Another common issue that GLC owners face is air suspension problems. Some GLC models have reported issues with the air suspension system, which can cause the vehicle to ride rough or even bottom out.

If you are experiencing air suspension problems, it is important to have them checked out by a qualified mechanic as soon as possible.

Battery Issues

GLC owners have also reported issues with the battery. Some GLC models have been known to experience battery drain, which can cause the vehicle to not start or have electrical issues.

If you are experiencing battery issues, it is important to have the battery checked and replaced if necessary.

Towing Capacity and Equipment

GLC owners who use their vehicle for towing may experience issues with towing capacity and equipment. The GLC SUV has a tow rating of up to 3,500 pounds, but it is important to ensure that you have the best towing equipment for your GLC to avoid any issues.

If you plan to tow a 2-tonne boat, for example, it is important to ensure that your GLC is equipped to handle the weight.

Mercedes GLC Engine Recall

If you own a Mercedes GLC, you may have heard about the engine recall that affected some models. The recall was issued in 2019 and affected GLC models produced between 2016 and 2018.

The issue was related to the engine’s balance shaft, which could fail and cause the engine to stall.

If you own a GLC that was affected by the recall, you should have received a notice from Mercedes. The company will replace the balance shaft and associated parts free of charge.

The repair should take a few hours, and you can schedule an appointment with your local Mercedes dealer.

It’s important to note that not all GLC models were affected by the recall.

If you’re not sure whether your vehicle was included, you can check with your local Mercedes dealer or use the National Highway Traffic Safety Administration’s VIN lookup tool.

However, the GLC has generally been a reliable vehicle. According to Consumer Reports, the 2020 GLC has a predicted reliability rating of 3.5 out of 5, which is above average for its class.

If you’re concerned about the reliability of your GLC, you can also consider purchasing an extended warranty or service plan. These plans can help cover the cost of repairs and maintenance beyond the manufacturer’s warranty period.

Mercedes GLC Plug-in Hybrid

Now, you might be interested in the plug-in hybrid version, the GLC300e. This model combines the traditional gasoline engine with an electric motor, offering a more environmentally friendly option.

Plug-in Hybrid GLC300e

The GLC300e plug-in hybrid has a 2.0-liter four-cylinder engine paired with an electric motor, delivering a total output of 315 horsepower.

It comes with a 13.5 kWh battery pack that can be charged in about two hours with a Level 2 charger. The electric-only range is about 30 miles, which can be extended with the gasoline engine’s help.

One of the main benefits of the GLC300e is its fuel efficiency. According to Mercedes, it can achieve up to 67 miles per gallon equivalent (MPGe) and has a combined range of 320 miles. It also qualifies for federal tax incentives, which can help offset the higher price tag.

However, there are a few downsides to consider. The GLC300e is heavier than the standard GLC, which can affect handling and performance. The battery pack also takes up some cargo space, reducing the available room in the trunk.

Australian Engines Mild-Hybrids

In Australia, Mercedes offers mild-hybrid versions of the GLC, which use a 2.0-liter four-cylinder engine with an integrated starter-generator.

This system can provide a small power boost and improve fuel efficiency by shutting off the engine when coasting or idling.

The mild-hybrid system is less expensive than the plug-in hybrid and doesn’t require any charging infrastructure. However, it doesn’t offer the same level of electric-only driving or fuel savings as the plug-in hybrid.

Overall, if you’re looking for a more eco-friendly version of the GLC, the plug-in hybrid GLC300e is worth considering.

Here are some of the key safety features you can expect from this luxury SUV.

Some GLC owners have reported issues with their seatbelts, including difficulty buckling and unbuckling, as well as the seatbelt warning light staying on even when the seatbelt is properly fastened.

If you experience any issues with your seatbelt, it’s important to have it inspected by a qualified technician to ensure that it’s working properly.

In addition to seatbelt pretensioners, the GLC also comes with a range of other safety features, including:

  • Adaptive cruise control
