Model S 2015, both of my headlights are fogging on the inside. Made an appointment with Tesla, thru the app, pictures were uploaded, at the arrival was given a loaner (didn’t ask for it) they said it’ll take a few hours and they are busy now,10am. At 5 pm got a msg from them saying my S will be ready next day by the end of a day. In the morning my S was ready for a pick up, however Headlight did not get replaced or touched. Tesla service said it’s normal for all the lights to get that moisture inside since all the lights are not tight seal and the moisture comes and goes away. Q: why they didn’t tell me that at the booking, at my arrival and made me waiting for my S to be fixed. Don’t they know it’s normal, or they had to replace them and they didn’t? My 4 year warranty is about to expire in 10 days from now. Wanted to make sure I don’t need to pay for those things later. Did anyone had a similar experience with the headlights or any other lights? Thank you for your help..
