Just got official reply from Nissan GB :
- 'ALLOW ME TO REFER YOU TO SECTION 2.8, SUBSECTION 4, OF YOUR NISSAN WARRANTY BOOKLET WHICH STATES THAT YOU ARE NOT COVERED FOR 'DAMAGES , FAILURES OR CORROSION RESULTING FROM ; MISUSE,ACCIDENT,THEFT,ARSON OR INTENTIONAL DAMAGE.' IT IS THE OPINION OF NISSAN GB THAT THE DAMAGE HAS BEEN CAUSED BY AN EXTERNAL THIRD PARTY INFLUENCE OF WHICH NISSAN GB HAD NO CONTROL OVER.
Not unexpected but how they think bubbling of spoke areas and around the nuts section is caused by anything but poor workmanshipn I don't know.Maybe they think wheels are not meant to be used on the road in any conditions ! The section they refer me to doesn't mention third party influence and I can't find that Nissan's opinion forgoes all aspects of their warranty.
This will be an interesting battle from now on.!!
