I have a 2008 titan with 37500 miles. Has a bad leak under the radiator now. Right over Bumper-to-bumper. My truck has has leaking antifreeze since the day i bought it. Ive had them fix it like 5 times and it makes the serpentine belt squeak so they have fixed that numerous times too. Its rediculous. I have some receipts from when the fixed it before (radiator cap and serpentine belt usually) under warranty. Ive spent $100,000 at this dealer with 2 titans and an armada. If i go in and throw a fit on how they should have fixed it in the first place and blah blah do you think they will fix the radiator under warranty? Ive had nothing but problems since day 1. I think i might call 1 800 nissan1 and throw a fit and see if they will call the dealer and work something out. Anyone have advice??
