For the wobble, what often times happens is if the outside electric folding mirrors are folded in and out by hand (and not the button) which commonly happens when going to a parking garage and leaving it with an attendant, slack develops between the mirror housing and its base. That in turn leads to vibration of the mirror when you are driving the car
What you can do to eliminate the slack is to fold the outside mirror all the way forward by hand, then press the switch (that normally folds/unfolds them). The system will react as though it is trying to fold the already folded mirrors. It will start an initializing routine which you can identify by the loud clicking noise that will take place. After it completes the routine (a few seconds) the slack will have been taken up by the mechanism and the problem should be resolved. If it doesn't improve, then run it again.
