we've had our 2020 450 about a month now and recently it started to squeak ALOT at low speeds over any road devotions. I cant tell if its the door seals or the sunroof. when the car is parked I cannot recreate the sound by pushing or pulling on the doors/sunroof so I'm not sure exactly where it's coming from. I have noticed slamming the doors reduces the sound, so I'm leaning toward the door seals. Recently had the car ceramic coated so maybe the door jams or super slick not letting the seals "grip", not sure why they'd coat the door jams so I highly doubt that is it.

IDK at this point, maybe this is a common issue?

Think I figured it out. I used silicone spray on all the weather stripping and it stopped. I'm sure its whatever product he used to decontaminate the car before he coated it stripped any sort of lubrication on the stripping.
