2022 MERCEDES BENZ GLC 300 Steering Problems

I was driving home on a 4 Lane Expressway on a Saturday afternoon, it was mildly raining with the roads a little wet. I suddenly lost control of the car and could not control the steering wheel, the car ended up hydroplaning and I lost control it ping-ponged across four expressway lanes back-and-forth about 20 to 25 times with zero control of the steering wheel, barely missing the medians and other cars. It should have been a massive catastrophe. Cars around me you had to stop and swerve around me to avoid hitting me all while driving on the expressway. Had someone accidentally hit me in the process it would’ve certainly flipped the car and I would’ve either ended up dead or in the ICU. After several minutes somehow without moving the steering wheel, I managed to just go straight and pull over. And waited for help to get back safely slowly. I thought the incident was isolated because the roads might have been the cause. But I went out out of the country and upon coming back, drove my car again on the expressway coming back home and the exact same thing happened with my minor child in the car across two expressway lanes in the evening time With the roads perfectly dry. Lost control of the steering wheel could not steer or direct the car and had to jerk it from to prevent it from driving off the highway. It seemed to have occurred both times at a higher velocity on expressways when the steering wheel needed to be engaged. I had it towed to the Mercedes Benz Of Coral Gables dealership, but they cannot find anything wrong with the car, even though the exact same model of my car has an active recall for 2023 and 2024 models. For the same problem, I later learned. Mine is a 2022. I have been in a loaner vehicle for three weeks while they investigate and I need Assistance to make sure that something gets done because nothing has been found and I do not want to risk driving with my child in the car.

Loss of Steering Control at Highway Speeds – 2022 Mercedes-Benz GLC300 Vehicle: 2022 Mercedes-Benz GLC300, VIN [XXX] Dates of Incident: September 13th and October 4th Mileage at Time of Incident: 39,500 While driving on a four-lane expressway at highway speeds, my vehicle suddenly and completely lost steering control, resulting in a total inability to steer. First Incident The first event occurred during light rain with mildly wet road conditions. Without warning, the vehicle hydroplaned and violently crossed all four lanes approximately 20–25 times, narrowly avoiding collisions with other vehicles and medians. The steering wheel was completely unresponsive. After several minutes, the car inexplicably corrected its course. Second Incident The second incident occurred weeks later under clear, dry conditions with my minor child in the car. Once again, the steering wheel locked, leaving me unable to direct the vehicle. I had to physically force the wheel to prevent the car from leaving the highway. Investigation The car was towed to Mercedes-Benz of Coral Gables, where technicians were unable to find any fault despite multiple diagnostic attempts. I have since discovered that 2023 and 2024 models of this same vehicle are under active recall for a similar steering malfunction, which may indicate that 2022 models are also affected. Safety Concern This defect poses an imminent risk of fatal accidents, both to occupants and to other drivers. The failure occurs without warning, at high speeds, and results in total loss of steering control. Requested Action I request that the NHTSA investigate whether 2022 models should be included in the existing recall related to steering control failure in Mercedes-Benz vehicles.

The vehicle's steering wheel vibrates noticibly between speeds of 47 mph and 55 mph. This issue was once addressed with a "software update" by Mercedes Benz of Portsmouth, NH. Streering wheel vibration is a concern for any driver that rely on power steering to turn or hold the car steady. In addition it creates unnecessary panic for some drivers. This issue is brought to Mercedes Benz multiple times. I had replaced all the tires at 19,000 miles, balanced, got tires aligned by Mercedes Benz dealer and the issue persists.

There is a significant steering vibration as the front wheel drops in a common pothole turning at speeds above 30 mph. There is a loss of control as if the wheel is skipping. It feels like the shock absorber continues to vibrate for a few seconds. I did mention this to Mercedes-Benz during the annual maintenance service but they did not do anything.

Steering wheel vibrates when it travels over bumps or road irregularities at freeway speeds.

The contact owns a 2022 Mercedes-Benz GLC300. The contact stated while driving over 50 MPH, the steering wheel was vibrating. The vehicle was taken to the local dealer who was unable to duplicate the failure. The contact continued to experience the failure. The contact took the vehicle back to the local dealer and was informed that the vehicle was repaired under an unknown manufacturer recall and the steering wheel bracket was replaced, and the steering wheel software was updated. The vehicle was repaired but continued to experience the failure. The vehicle was taken back to the dealer however, the dealer was unable to duplicate the failure. The contact continued to experience the failure. The contact took the vehicle back a fourth time, but the dealer was unable to duplicate the failure. The contact continued to experience the failure and the vehicle was taken back to the dealer however, the dealer was unable to duplicate the failure. The vehicle was taken to a second dealer, Mercedes-Benz of Rockville Centre (110 W Graham Ave, Hempstead, NY 11550, (516) 766-6900), but the dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was 5,742.

Mileage: 5,742

Excessive steering wheel vibration after the software update. Mercedes main office in Georgia was notified and they instructed there is a fix after I threatened the lemon law. Time on dash will read random times, then will fix itself. Air conditioner will not run cold to drivers side.

Steering wheel vibrates uncomfortably and appears to lose steering effectiveness when the car goes over road irregularities when driving at moderate to high speeds. Irregularities experienced include driving over cross joints, bumps or dips on the road, and poorly repaired road surfaces. The sensation is disturbing and feels unsafe. The vibrations last for a few seconds each time. There are no warning signs or signals while this is happening. The vehicle is less than a year old and it has been doing this for a few months now. First time I felt this issue the car had approximately 3,100 miles. I made an appointment to take it to the dealership for it’s first 10,000 mile maintenance and will request to have this issue inspected.

At speed above 55mph , the steering wheel shakes in an abnormal and unsafe manner while traveling over a bump. This seems to be a manufacture defect and recall would be ideal. This seems to be an issue with all this model of the vehicle.

Temporary vibrations (LONG LASTING) noticeable on steering wheel when front axle excited when driving over road irregularities at a speed between 45 mph and 90 mph (70 km/h and 150 km/h). Excitation examples: • Driving over deeply recessed manhole covers • Driving over cross joints • Driving over extreme surface undulations

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.

I purchased my car 2022 Merced-Benz GLC 300 from Park Place Motorscar in Arlington Texas on February 17, 2022, and have issues with the steering wheel shaking when I drive over bumps. I have raised the problem with the dealership service department and they have not fixed it after 3 attempts. This is a safety issue and I am very concerned.

Driving on uneven surfaces the steering wheel start shaking and vibrating including the car body.

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).
