About the GLC
The compact crossover GLC first made its debut in 2015. Since then, Mercedes has released only two generations. The latest of these hit the markets in 2022.
The name of the model follows the standard convention for the latest Mercedes-Benz SUVs. The ‘G’ pays homage to the long-running G-Class series, while the ‘C’ indicates that it is in line with the C-Class in terms of quality. The ‘L’ was given to distinguish the SUV models.
The crossover class has become very competitive, putting the GLC up against some serious contenders. Of course, when it comes to a Mercedes model, the main competition comes from the Audi Q5 and BMW X3. Other notable competition comes from the Volvo XC40 and Porsche Macan.
Interestingly, the most common fault code that the GLC faces is P2000, which is a fairly rare code. This indicates that the NOx trap in the exhaust system is not functioning properly.
This code can be a sign that the catalytic converter is failing, which makes it important to have it checked quickly to prevent expensive repairs.
Another issue that the model faces is one that a few Mercedes-Benz SUVs face. Fault code P0171 indicates that the engine is running too lean.
It can be very problematic just to find the cause of the issue. Anything that is part of the air or fuel systems can be the cause of the problem.
Another fairly serious problem that the GLC is known for facing is P0100, which represents a circuit malfunction for the MAF sensor. Owners have reported that a dirty MAF is one of the most common causes of the issue. This is also true of a faulty sensor.
