“Wipers - I have had repeated issues with the windshield wipers on this vehicle. I have taken it to the dealership 3 times and I have not gotten a satisfactory solution to the issue.

I've also been told they can't recommend a solution. AC - The AC in my 2021 GLS 450 smells like moldy socks which makes me suspect there is some build up on the coils or in the vent. …”
