Went to dealer to get a plastic washer put on the stock bed liner cause one was missing and dealer told me that it came from the factory without it and there's nothing they can do.Also told me that the slack on the right cable on tailgate is normal for the late model 05's.Told me that they can't replace any part of the gas nozzle to tank(mine overflows when below 1/4 tank)unless the CEL comes on.They also said that I wait till below 1/4,bring it in and they will try to duplicate it at my expense.What should I do?I tried to look for the thread about the gas but couldn't find it anywhere.Please help?This dealership is WALSER NISSAN in BURNSVILLE,MN.
