It's not just the plastics exposed to the crazy heating and cooling cycles that have this problem, though. That's why I mentioned the IKHA buttons and cluster stalks specifically. Another good example of the interior plastics becoming very brittle is the window regulators and the clips that actually hold the windows to them, or the clips that hold the door cards on, or the pieces of the moon roof that break, etc.

The ones in the engine bay that are exposed to the heat are definitely worse off though, I agree 100% there.
