The Mercedes-Benz GLC is considered one of the German automaker’s luxury crossover SUV models. It was first introduced in 2015 as a 2016 model year SUV. At that time, it replaced the previously-loved GLK-Class models. It’s also considered an SUV equivalent to the C-Class models, with comparable equipment. While this model is compact in nature, it’s listed as a mid-size SUV when compared with others on the road.

Mercedes-Benz has enjoyed a lot of success with recent GLC models. In 2021, there were 51,805 units sold. These sales numbers made it the second-most popular Mercedes behind the GLE, which sold 65,074 units. In comparison, the third most popular model, the C-Class, sold 30,815 units.

Most Common Problems with the 2022 Mercedes-Benz GLC

Despite the popularity and continued success, the 2022 Mercedes-Benz GLC has shown numerous defects that are causing some concerns. It’s unclear yet whether these defects will cause Mercedes enthusiasts to jump ship or not, but they are being closely watched to see what the outcome could be. The top issues are electrical, safety system and steering problems.

Electrical System Problems

  • Glitchy Operations: No one expects a car to roll its windows down independently or for the radio to turn on without input from the driver, but that’s what’s happening with some GLC300 models. One driver acknowledged that both the windows and moon roof opened on their own, with the radio turning on by itself a few days later. Additionally, Bluetooth and GPS connections also seem to be faulty, even after a software update by the dealership.
  • Defective Garage Door Transmitter: Customers have been dissatisfied with the garage door hand transmitter installed with the GLC-Class. According to manufacturer technical service bulletins, the integrated garage door opener might not work properly without a necessary repair.
  • Heated Seats Not Functioning: Customers expect more when choosing heated seats, especially when temperatures start to drop. Yet, Mercedes-Benz has technical service bulletins expressing that the driver’s and front passenger’s seats might not function as expected. While the LED switches claim the seating is working, the mats never get warm. To repair the issues, customers have to visit a local dealership for reprogramming.

Safety System Problems

  • Faulty Distance Assist Distronic: One driver states that the GLC300 engaged this safety system on its own while driving 65 mph down the highway. This defect led the vehicle to slow abruptly, forcing the driver to disengage the system before an accident occurred. Even though this driver took the luxury vehicle to two dealerships, the problem has yet to be resolved, with the manufacturer claiming it’s operating as it should.
  • Defective Anti-Theft Alarm: Mercedes-Benz isn’t shy about sharing information about the defective alarm system. Technical service bulletins reveal that certain models of the anti-theft alarm can activate without any cause. This defect is causing people to disable the alarm and it can lead to being less aware of situations when the alarm is going off, thereby putting the vehicle in more danger of being stolen.

Steering & Handling Problems

  • Rough Ride: There are multiple reasons that customers are complaining about a rough ride behind the wheel of a GLC. Some find that it has something to do with the run-flat tires that are installed. For other owners, the roughness seems to be related to steering complaints. Either way, customers are struggling to get the problems resolved, despite various visits to local dealerships.
  • Vibrating Steering Wheel: When the GLC runs over uneven terrain or roads with minor imperfections, there can be temporary vibrations in the steering wheel. The problems seem to be most noticeable when driving between 45 and 90 mph. It also happens when going over a manhole cover or across cross joints. When hitting potholes, customers complain that the vehicle vibrates violently, almost to the point of losing control. Some dealerships have chosen to disable the Attention Assist setting to resolve the issue, and while this might make it better, it doesn’t cause a complete resolution.

2022 Mercedes-Benz GLC Recalls

At this time, there are no 2022 Mercedes-Benz GLC recalls issued by the NHTSA, even though it’s possible that some should exist. We will continue watching for additional updates, ensuring that consumers always have access to the information that’s important.

It’s possible that we will see many recalls in the future. In fact, the previous model, the 2021 Mercedes-Benz GLC, currently has seven recalls listed for it. For this reason alone, it’s hard to imagine that all of the problems and glitches have been worked out over one model year.

Description
Vehicle vibrates quite violently when hit some potholes. Steering wheel is the part that vibrates more but vibration is felt throughout the vehicle. It is more prevalent at highway between 55-65 mph speed. I also noticed that car shakes unusually and tilts to one side at times making it quite uncomfortable for driver. Back tires make slipping noice on potholes and feels like car is going to be unstable momentarily . All these issues are putting driver and others at risk. I joined facebook page of glc300 owners and almost everyone reported this kind of problem. For most of the people including me , it is still unresolved . I took my vehicle to dealer and they updated software but issue still persists.

Description
When driving at 40 to 60 mph and hit shallow pot hole or bump in the road the front wheels violently shake and the steering wheel (electric steering) violently vibrates for 5 to 8 seconds. Dealer checked the vehicle and claims there is nothing wrong with it but did turn off the "attention assist" setting from sensitive setting claiming it was the cause. The issue still exists but not as violent. I'm concerned of loosing control of the car/my safety. Fyi: never experienced this issue with my previous car (same car two years older ,2020 glc 300).
