Once you know there is a potential safety issue, you enter a huge potential exposure...MMC (and I suspect driven by their owners) have done the only thing a relatively small enterprise can do and played it very safe.
This is very similar to the small scope problem with the brake pedal on v early M3Ws that happened a few years ago (we were affected and had the same "do not drive until fixed" advice....albeit, the dealers were not so promptly told about it on that occasion).
A bigger deeper pocketed business might take more risk if they had evidence a problem was unlikely to create a number of serious incidents (which I understand this has not (yet) done for CX cars)
Hope the dealers can sort this for CX owners reasonably quickly
