Probably so, especially as I'm aware that there were a number of similar issues with the Micra that was blamed on tyres at the time. (Didn't find this out until after I discovered the Notes problems)
I have subscribed to a number of online Nissan sites and to be fair am totally underwhelmed by the lack of responses
Looks like I'll just have to put up with what we've been dealt and just make sure I never ever buy another Nissan ever again.
Good job I have my MX5 to vent my frustration on
