My father's VSX NSF actually suddenly failed whilst he was driving home triggered by catching a pothole!
I put it down to manufacturing defect of the one 'p' bush as it hadn't been fitted new on the car long.
The car was actually still driveable (just about!) with handling more akin to a lesser marque'd car!
The bush is rusty in the picture as the car sat for a while whilst an alternate arm was found and rebuilt
and the weather improved - I cannot see rust was the cause of the failure. I've never seen another
mention until now Adam so this does pose a weakness that has an opportunity to catch Xantiae owners
out and something to check for!!
