I just picked up my XC40 Momentum with 20 inch wheels on April 27. Drove to work on the 29th. Once I reach about 65 mph, I start to feel a vibration in the front of the car and steering wheel. Once I hit 70 mph, it becomes very noticeable. I did confirm with a few other owners in an XC40 Facebook group that they are also experiencing the same issue. They have had their wheels balanced, had alignments, etc and nothing fixed this issue. I spoke with the salesman and he just told me to have service look at it. I just want to know if this is a known issue and if others here are experiencing this. I dont want to have to deal with the service dept not really knowing how to fix it and will file a lemon law claim if this is something that cant be rectified. I really love this car in all aspects except this one annoying issue. Any guidance would be appreciated.
