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.
