 I bought a 2008 Pro4X new from Nissan, and it has not been one of my better vehicles.It's had numerous recalls, the gas milage is terrible, the locking differential has never worked, the driver's seats squeeks loudly, the rear doors rattle, and now the rear bumper is rusting.This is the last straw for me.Since the truck is 3 years old, and has over 36K miles, Nissan will not fix the bumper.I can't believe it!This truck was nearly $40K, has never been in any kind of accident, and Nissan won't cover rust?!They told me that the rust warranty only applied to body panels, and bumpers were not covered.The rest of my truck still looks new, and the rear bumper has a big rust spot!
