EDIT:
I do not know if the parts are the same, but chances are they are VERY related and supplied by the same company. Somebody with more knowledge can chime in or do some research.
As the article from Wardsauto quoted below implies, same company (JTEKT) supplies column mounted electronic steering systems for many vehicles to GM and Toyota and others. JTEKT, a spinoff and merger between a Toyota company and a Seiko company and still considered in the Toyota Group and probably majority owned by Toyota, is the leader in electronic power steering components, among other things.
If they are the same or are very related, this needs to be brought to the attention of GM.
I have not looked into the latest recall yet.

........."JTEKT uses four U.S. plants to supply steering systems to Toyota’s North American-built Avalon, Camry, Sequoia, Sienna, Solara, Tacoma and Tundra, all hydraulic types; and the Corolla, Matrix, RAV4, Venza, Lexus RX 350 and Pontiac Vibe, all fitted with column-mounted EPS.
General Motors Corp. programs include the Chevrolet Cobalt, HHR and Equinox; Saturn Sky and Vue; and Pontiac Solstice and Torrent. In addition, JTEKT supplies the Suzuki XL7. Most are column EPS.".............
