Unlike in the U.S., Toyota Europe will not be suspending production of any models because replacement parts are already being used at its various assembly plants. What's interesting to note is that some of those plants are located in Japan, specifically ones that build the Corolla and RAV4. Until now, the reason given for all Lexus and Scion models being excluded from the recall was that they were built exclusively in Toyota's native country and used an accelerator pedal mechanism sourced from a different supplier, not CTS Corp. that manufactured the defective part for North American plants.
Whether or not this means the recall could be expanded even further, perhaps to include vehicles from other Toyota brands, remains to be seen, but the fact that the defective part in question has now popped up on the other side of the Atlantic suggests that the problem lies in its design and not how it was manufactured by the supplier.
