Guys,
I don't want to miff you off anymore, but just wanted to say..... don't give up!
I've just got my brand new Rays, full set replaced yesterday. I took them in about 2 weeks ago, the dealer took photos, I explained the situation and that I knew what to expect from Nissan about fob offs etc and that I would be pursueing all the way......
Anyway, the photos were accepted by Nissan from the dealer, then they got the go ahead to order new wheels on the system within a few days. Wheels went in on Monday evening and tyres swapped over to new ones Tuesday and balanced. I got no pain or come back what so ever, was expecting the same about me using acidic products blah, blah...... the bottom line is that the wheels are not fit for purpose for UK roads if they do this.
I know I got a major result and was very lucky as end to end was replaced within 2 weeks (and that included ordering of wheels).
The bottom line (I think) is that it depends how "customer focused" your dealer is. I was told by mine that they don't get any money out of doing this work, they just get base rate to cover their costs on labour etc..... so in some cases, it could be that the dealers are not exactly pushing it through.......
I'd suggest trying another one if you get no joy...... suppose it helps that my car has been serviced there. Might not be so easy otherwise.....
PM me for anymore details etc..... not sure I can help more, but will try.
