What's this deficiency you speak of? In that light, every other part on our cars have a "deficiency."
What's its deficiency? The fact that the DISA can blow up the motor when it fails. That's a very poor design.

Wear and tear failure would a singular failure mode, for example the vacuum failing, so the DISA flaps around but doesn't disintegrate.
