Tonight, my driver's side external lock button seems to be sticking and no longer feels springy like before (or compared to the passenger side) and is causing issues locking and unlocking the car from the handle. If I pinch the button and wiggle it I can get it to cooperate, but it seems to stick again next time I push it. When it is sticking like this, grabbing the handle or touching the inside of it does not unlock the car either. I am tempted to spray a little contact cleaner in there, but can't remember if it will hurt the paint, and plus, this is why I have a warranty. Anybody else run into this issue?
