Found the top vent loose doing first cleaning inspection. 2016 cougar 5er. Likely flapping in the breeze when driving for some time. The "corrected to not mislead" proflex clear (not silicone) caulk was no longer holding on the bottom and two sides. Could have come detached and been a safety hazard. Normally should have 4 screws top edge and bottom. 1 screw on each side. The side and all bottom screws were never installed from the factory. [emoji3064] just fixed er up in the wonderous Florida weather. Checked the bottom vent. All looked good. The guys at the factory must have forgotten the one last ladder climb to get those last six screws in? [emoji848]
