Has anyone heard of a problem with the "High Mount Stop Light Assembly" coming off when using a full service car wash? I returned from a week on the Gulf Coast yesterday and decided to have my Armada washed to remove any sand and salt residue. I was informed that they have problems with QX56s and Armadas losing the rear high mount stop light assembly. I was told that it is only held on with 2 clamps and double-sided tape. Needless to say, I did a drive-around and came home and washed it myself.
