NHTSA Complaint #11463322 — 2018 SUBARU FORESTER

Smelled car exhaust entering the cabin, took to dealer for inspection. Exhaust manifold part is actually warped and separated from the engine (not gasket issue). Apparently this problem is known by the dealer service shops, but is undisclosed by Subaru. I was feeling quite sick for weeks without understanding the cause, now I drive the car with the windows open and the vent closed and feel much better (I am waiting for the part to arrive so the dealer can fix the issue). I am an engineer and described the issue as a defect, the dealer hedged and said they are not allowed to call it a "defect" since that implies it needs a recall.
