I have just phoned the dealer, and i am amazed, he said "i was just about to phone you it's all done" valeted ready for pick up. he told me the battery has been replaced because the other one was no good? that is a bit worrying. anyway i will pick it up and see how it goes.Hi Andy, this was the outcome with mine too.... it’s been with the dealership for 4 weeks (part on back order story) but I am now being told that they have absolutely no idea when the part will be available (mutterings about maybe March!) so don’t hold your breath! My local dealership said this is a well known fault with the truck but they can’t understand why it’s not been resolved. It is causing me a world of pain and put me off ever buying another Nissan! Do keep us updated with yours.
