Recently bought a used car from Mercedes-Benz of Bellevue and there is an issue with comfort access on the driver door. I called on the 3rd day while I can still return the car and I was told that they will find a way to fix it. Now AutoNation insurance declined the claim, I am waiting on the dealership to decide if they will cover the $1000 expense or not. In general, I am disappointed that I have to go true all this when they missed to catch the problem during the inspection.
