So I just bought a 2019 diesel truck, I picked it up after dark and did a quick visual inspection of the truck and either missed the fact that one head light assembly had moisture in it or it happened...
I've seen GM deny warranty because the vehicle had a car wash pass sticker on it. Claiming the "high pressure" caused the driving light condensation. I've also seen a Honda Service Manager claim an OE headlight MUST be aftermarket because it had water in it. Neither one of these were my vehicles but close friends. My Silverado driving lights both have condensation in them that I ignore for the simple fact that I don't have time and don't need the aggravation of trying to get them warranted.
