Ok, here's the thing - that probably related to an incorrect mounting / fixing, so a mechanical defect or misalignment issue potentially? So that has the potential to cause loss of steering and hence the safety recall.
The C5 rack is mechanically fine, but the quality of the steel used in manufacture is certainly of poor grade and quality. The issue with this is that it leads to corrosion and ultimately deformation of the seal / inability to make a seal. That will very likely be put down to a wear and tear / ageing issue I suspect. It probably won't lead to sudden and unexpected loss of steering and certainly in the case of hydraulically sprung C5s, would result in a warning for low LDS level before it actually ran out of oil. So plenty of time to top it up and get it to the garage I think.
I guess mine was leaking for some time before I noticed it, as I have had steering track related LDS leaks twice now of course, plus with the rear pipe and the front strut going too - so my gravel has been bathing in LDS lately
So unless it is going to be a catastrophic failure or life in imminent danger, I really don't think they will give a fig about it.
I mean, in a few years here on the Forum, we'll all be saying to each other "How many engines are you on so far?... Oh, just the second, I'm on my third one now..."
