Dash MELTED?!?!?

Ok, I am almost convinced that this Bimmer is cursed. So I am driving this afternoon and notice that the little silicon/rubber mat where my radar mounts onto on my dash was not laying flush with the dash. So I go to straighten it up, and was HORRIFIED to see that under the silicone mount my dash had... MELTED?! It looks as if maybe the mold under the leather lining had melted. I am no chemist and I have no idea why this little piece on my dash would have caused it to melt, especially since I always keep my car covered with a UV protectant cover and it is rarely left in direct sunlight.

I am OCD especially about my interior and wipe it down and condition the leather practically every few uses, so this really is killing me to look at.

Does anyone have ANY ideas what would have caused this? Is plastic/silicone a SUPER attractor of heat or something? Is it some crazy reaction between light through glass and silicone? Also has anyone ever had to replace the upper, leather section on an E90s dash before? Any info they'd like to share?

I'm SUPER ANNOYED... I keep my car covered and take such good care of it precisely to avoid such wear, and now I have a deformity from some random one-in-a-million chance reaction. Anyway, to be safe, i'd avoid any similar products (there are many on the market, for holding various items) with leather in the car and especially where it is molded leather

Wow! I can feel your pain from here....looks like maybe your I-drive is running super hot? Hope you can find the cause of that.

.

Silicone mat..... Among the best insulators, it prevented underlying heat to escape.

Feeling your pain but there may be no remedy. What's dealer say?

Dash MELTED?!?!?

Sorry to hear. If if were not for the photos it would be hard to believe this is even possible. I wonder whether it is the materials in that mat and maybe some chemical reaction with the dash.

Did you get a quote for a replacement dash?

What chemicals are being used to keep the dash shiny? Reapplied every few days?

It could be the chemicals, plus heat, plus the silicone mat.

Yea don't THINK it's from the i-drive... I think silicone as an insulator is sound reasoning, the question is if it was insulating heat from the window heating the dash panel, or if its heat coming up from the i-drive and other factors from under the dash. But clearly, the marks ONLY appeared under the mat, so it was the main factor.

As far as chemicals nothing crazy. I use high quality McGuire leather conditioner wipes.

Haven't yet mentioned anything to the dealer as unfortunately this is the LEAST of my problems as the car is running super rich, and God knows how many things are wrong with it since I just purchased it used from Toyota... Basically got screwed. Not even sure how the car passed smog, but anyway about to take it to the shop and spend BIG money on walnut blast, probably full new set of injectors, and who knows if even that will solve the issue. No point fixing aesthetics when the mechanics are a mess. I am sensing it will turn into a money hole, so I think i'll buy a horse instead and seek legal counsel to see if anything can be done about Toyota.

That might be the problem... the dash is not wrapped in leather, I believe it's made from a rubber and polymer mix.

You could just put a slightly larger (non insulating) mat down over the area and live with it. Only you would know the horrors that lay below the pad.

Black (absorbs heat easily) silicon mat heated up the dash underneath it, acted like a nice blanket, which caused the glue to melt under the dash coating.
