My truck 2012 Frontier looks great. Outer panels are double galvanized. Have a life time warranty for original owners, but the outer panels are doors and fenders only. The rest of the truck is a cheap untreated hot rolled steel. Mine is rusting threw the bed in several places. This problem is made worse by the factory spray on liner that hides the rust until it bubbles and is a hole. Nissan made a management decision not include the bed in the outer panels that got the double galvanized steel that would have cost them $40 per unit. I contacted Nissan and they declined any help. No way should a 2012 truck rust through with today's steels. When buying your next truck or car remember the company that wants to save a couple of bucks at your expense. Thanks

Update from Jul 28, 2019: I sanded the bad spots and found the steel to be bad. I worked in the Cleveland steel mills for 33 years as a melter and know laminated steel with inclusions.We never sent steel to customer that did not meet his specs. It was marked down and sent to our warehouse as a secondary product.So where did Nissan get the steel that made my truck bed. This is not isolated event altimas have this defect and are rusting through the floor boards even in the southern states.The Titantic sank because of bad steel dont let Nissan sink your investment in there products. thank you

I purchased a BRAND NEW 2012 White Nissan Frontier SV 4wd in April (4 months ago) Sunday while washing it, which we do twice a week, I noticed rust spots on the bumper and just behind the read passenger door under a piece of dura tape. Of course I paid extra for the premium protection package which included paint protection. Apparently according to the dealer rock chips causing it to rust isn't covered. Its a painted bumper, not chrome and apparently this is the norm???? We live in the Midwest where we are in a drought and the possibility of rust in such a short period of time mystifies me. It's not the first new vehicle we have owned and NONE of them (Chevy, Dodge nor Ford) had one ounce of rust even after having them for several years. Heck my 2007 Mazda 3i still doesn't have rust on it, nor does our 1995 Lexus. I think it's a faulty paint job and/or badly designed bumper. I am at a loss of what to do but am very irritated that I spent almost $30.000 to drive a rust bucket..I can't even imagine what it will look like this winter after the salt/snow gets to it. The dealer solution have the bedliner sprayed on it.. I could always purchase a chrome bumper for almost $700.00 but I think Nissan should fix it.

Update from Sep 26, 2012: Update: It's been fixed by the dealer after I made several written complaints to Nissan and to the original dealer. They had another 2012 Frontier that showed the same rust occurring, this is obviously a defect in the painting process for those painted bumpers.
