Complaint Review: General Motors Hanwha Machinery

GM General Motors allowed one of its foreign owned needle bearing suppliers through poor audits to use low grade chineese material in its GF6 GT40 transmissions and hub spindle assemblies , this was done heavely on the "New GM" product and searching google on various terms like GM- hub- bearing -transmission- failure -problems (mix it up for different results) lots of low mileage failures and poor warranty support , hourly employees were directed under YC Kim of Hanwha Machinery Hanwha Solar to start using this product in a plant wide meeting, as problems arose with failures low level managment would blame a hourly employee for  "used wrong material" and spread the rumors, I filed a SEC security exchange commission complaint which was denied and not investigated, also the FTC was never adressed , I believe this problem was enabled by GM to try and control failures for the secondary owners with no recourse and quicker new car sales.
