Just had my 16K oil change and safety check. Nissan Dealer found Positive Battery terminal corroded and battery case cracked at the post. Tech told me that its a common problem he sees with the newer Nissans. Warranty work, so I had to go down the street to Infiniti. Sure enough, bad battery. Replaced terminal and Battery. Thanks to both Larson Nissan of Fife and Tacoma Infiniti in Fife.
