How come there is no recall on the pcm

What is your question?

I have replaced my catylitic converter all the spark plugs had a melted coil on primary a code reads out secondary system was miss diagnosed twice spent almost $2000 on it already trying to fix the problem replaced saved myself $1000 by doing the upper intake gasket myself and replacing the coil and plugs only to find out that the violent shake is actually due to pcm or ecm unit which has cause the number 1 coil to (melt) the faulty unit may catch car on fire burn all 6 coils and leave you stranded but enough ppl haven't actually reported the problem correct and some have not even gotten this far to solve it due to the code that was popping up of P0351 was miss diagnosed and solution was found through process of elimination this being said it's an awful amount of $ to be putting into a car with only 100,000 miles on it and is not due to wear and tear
