Had a little bit of condensation in the front left headlamp and some ice crystals inside the right rear tail lamp. Anyone know if GM would replace those units under the B2B warranty? Do I even waste my time trying to duplicate it and show a service advisor?
Well, for what it's worth, my 2018 bought in November, both headlights needed to be replaced 2 weeks after I took possession of the car. I drove with headlights on all the time, even went on a 600km short trip on the first weekend and the fog would not go away. I went to the dealer, they looked at it for 30 seconds and said the fog would never go away so they ordered 2 headlights and replaced them. Haven't seen fog in them ever since.
I also noticed the fog in my driver side headlamp. I took a picture of it on my phone to show the dealer, just in case. It has gone away for now. Its probably waiting for the warranty to expire before it comes back full force!
