Purchased a 2013 frontier last Sept. Noticed a slight wind noise. It's has proceeded to get worse. Have taken it to the dealer a couple of times now. Had the outer door gasket replaced. On the open highway it's worse due to increase in speed. The dealer is telling me it's a design flaw and have blown me off. Telling me to purchase window visors for the truck, stating this might help. I want it fixed by Nissan.
