I noticed severe rust on the painted bumpers of my 11 month old Titan Pro-4x. Usually the Titan comes with chrome bumpers, but the Pro-4x model has painted bumpers.
Clearly the quality of the paint job is not up to standard, but Nissan refuses to give me a dime towards the repair. I even offered to pay for any additional protection if they could just have the area fixed to a 'like new' condition.
It's worth noting that I am a web designer and the truck has not been worked hard. The front bumper has a few chips in it too, but there is no rust.
My advice: Only buy a Nissan if you plan on driving it indoors.
