It would be like parking right up close to a huge fire, then complaining to Toyota because the plastic melted.
Your claims of Toyota using cheap ABS Plastic is totally unfounded.
Add Jimmyh to the list of poster that are guessing, here are a few of his other comments on the subject:
"The sun did not do that.
Neither Southern California or Waco Texas get up over 212 Degrees F even in the worst summer sun. That was exposed to something very hot. Notice it didn't melt all over, mainly in one area. It looks like someone used a propane torch on it.
I have never seen any ABS Plastic melt in that way from the sun"
I agree. The ABS Plastic doesn't reach the Glass Transition Stage until it gets to ~ 105 degrees C or 212 Degrees F. There would be other damage to the vehicle if the reflection from a window were causing it. That mirror looks burned like a torch or some other concentrated heat source was applied just to that area of the mirror.
Gotta throw the old "Bull Shit Flag" on this story.
Is there any damage in the area besides the mirror? At 212 degrees on the mirror to cause this as if from a reflection there would almost certainly be some paint damage etc somewhere in the vicinity. It appears to be concentrated in just that area.
See my point?
Toyota uses the same ABS Thermoplastic that all mfgs use. No one on this ( or any other forum) has a crystal ball to tell you what happened to your mirror housings. We do not have enough information.
What we do know is:
1. Your mirror housing(s) got burned. Seems concentrated in one area.
2. ABS Plastic reaches glass transition at 212 F.
3. The sun doesn't get this hot on its own ( unless through a magnifying glass etc...)
4. If this was a common phenomenon it would be all over this forum ( and all other Toyota forums) in spades.
jimmyh, you are no expert, don't post like one, show some proof quit guessing and maybe I will change my mind.
