Mobile coming next week. Mine literally happened over night. Wasn't more than 80° so I wouldn't think that heat had anything to do with it.
No, I guess not. An overnight issue without high temperatures is hard to explain unless there is a seal to the air which can leak abruptly exposing the entire thing. If the glue is sensitive to oxidation it would not take much of a leak to allow oxygen to reach the entire display.
But then it doesn't really matter why. The issue is it should be covered under warranty.
My real concern is that when they fix it, they won't fix it with a unit that will not have the problem. Are brand new cars still seeing this issue?
