5 Engine And Engine Cooling problem

Failure Date: 06/30/2021

My left hand (front bank) catalytic converter near the cylinder head fell off yesterday at the mounting flange. It landed in/on my fan. I went online to find a replacement part and found gm service bulletin pip5419a & b first issued in 2016. . That bulletin explains a known "defect" with the weld. The catalytic converter pipe cracks at the mounting weld. The TSB was issued for all Impalas from 2014-2016, all vins all transmissions, all 3. 6l rpo lfx engines. It says that gm is working on a solution for this concern. Why isn't there a recall on this defect? the file I've attached is not from my car but from the TSB. It's very similar to what my cars catalytic converter looks like.

Owners of 2014-2015 Impalas are not able to get this part call the rocker arm control valve. They no longer make this part to fix the cars. So people who own those model cars are forced to trade in cars that their still paying car notes on. GMC has not spoke about this matter and left their customers stuck out without warning. We are forced to go back into long term car notes when half of the people almost finished paying off their note. And others have paid off their car that's 5 years old that they can no longer buy. It's very said .
