Is that true that in order to keep the waranty i have ot fallow maintenance provided by NISSAN....???
A lot of money:-(

 

I believe you have to show that you adhered to the maintenance schedule. You do not have to have Nissan do the service. For example, you can show that the oil was changed but do it yourself (keep good records and receipts if you can).

I'm not a lawyer so take this for what it's worth.
