My March 2021 MY has been having vibration/major road noise issues. Around 55+ mph, the car vibrates and the wheel shakes noticeably. August 24th, the SC did re-create the problem and their solution was re-balancing all 4 tires. However, this caused the car to vibrate again. If I drive the car 90-110+ mph (Just to test not regular driving), it feels like the whole thing is about to fall apart. The car is not stable or planted when at high speeds, like my Audi or Honda. I don't drive the MY aggressively or let it sit to cause flat spots in the tires. I have also never ran over a major pot holes to potentially bend a rim. I am stuck on what the problem could be. I was also thinking of potential tie rods and control arms fault. I have set another appointment with the SC.
