Common 2020 Mercedes-benz Glc63 problems

The 2020 Mercedes-Benz GLC63 has been reported to have several common problems based on complaints from owners. Here are the details of these issues:

• Roof Panel Bonding: Certain 2017-2020 Mercedes-Benz vehicles, including the GLC63, are being recalled due to a potential issue with the front roof panel bonding. The front roof panel located between the windshield and the panoramic sunroof may not have been bonded correctly to the vehicle during a prior repair. This could cause the roof panel to detach, increasing the risk of a crash.

• Crabbing Issue: Some owners have reported a "crabbing" issue with the GLC63, which is related to the all-wheel-drive system and summer tires. This issue can cause the vehicle to pull to one side while driving straight, making it difficult to keep the car in a straight line.

• Tire Longevity: The GLC63 comes with high-performance tires that are expensive to replace. While the tires can last a long time with proper maintenance, they may need to be replaced more frequently than on other vehicles due to their high-performance nature.

• Start/Stop System: Some owners have reported issues with the start/stop system, which can cause the engine to turn off and on unexpectedly. This system is designed to save fuel by turning off the engine when the vehicle is stopped, but it can be turned off if it becomes a nuisance.

• Transmission Issues: Some owners have reported issues with the GLC63's transmission, particularly in S+ mode. The transmission can be harsh and difficult to modulate, making it difficult to drive smoothly in certain situations.

• Fuel Economy: The GLC63's high-performance engine is thirsty, with some owners reporting fuel economy as low as 16 miles per gallon in mixed driving.

• Electrical Issues: Some owners have reported electrical issues with the GLC63, including the engine shutting down unexpectedly while driving and issues with the car not starting.

• Auto Stop/Start: Some owners have reported issues with the auto stop/start system, which can cause the engine to turn off and on unexpectedly. This system is designed to save fuel by turning off the engine when the vehicle is stopped, but it can be turned off if it becomes a nuisance.

• Hybrid Battery Issues: Some owners of the GLC350e hybrid model have reported issues with the hybrid battery, including complete failure of the battery and issues with the battery management system.
