On my 2021 lexus rx350l, the left-hand side outer rear-view mirror vibrates. This can be observed when the car is driven >35mph or when driving on rough roads. At freeway speeds, the mirror vibrates to such a degree that it is difficult to see from it and causes perception issues. I noticed this issue even more pronounced on some other 2021 rx350 vehicles that i test drove before purchasing the one i own. The issue seems to mimic that of l-sb-0058-22. I suspect the cause and remedy are likely the same.
