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).…

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.
