The minis share the same electronic pedal assembly design used in the 2.3 million Toyotas being recalled in North America, as well a 1.8 million vehicles in Europe. In addition to the Aygo, Toyota has identified the iQ, Yaris, Auris, Corolla, Verso, Avensis and Rav4 in Europe. In total Toyota is recalling 7.5 million vehicles worldwide.
We don't know for sure but it seems unlikely with this many vehicles involved around the world that CTS is the sole supplier of these parts. If CTS is not the only supplier then it appears likely that the issue is more of a design problem than a manufacturing issue at one plant or supplier. It is also possible that it could be a software issue unrelated to the hardware itself.
Update: We checked with Toyota spokesman Curt McAllister who confirmed that Denso is the other major supplier of this pedal assembly.
Update 2: Curt McAllister sent us a note to clarify that CTS and Denso are the pedal assembly suppliers for North America only. We're not sure who the suppliers are for overseas markets including Europe and Asia but we'll look into it.
