One problem related to windshield has been reported for the 2007 Nissan Armada. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Nissan Armada based on all problems reported for the 2007 Armada.
Bought the vehicle new in January, 2007. Noticed a crack in the windshield one day in April without a particular incident to have caused such a crack. There was no indication that a rock had chipped the windshield causing the crack. A new windshield was installed on 5/2/2007. Afterwards, I have knowledge of three other 2007 model Nissan vehicles (armada, altima, titan) that have similar windshield cracks without apparent causes.
