The National Highway Traffic Safety Administration has announced two separate recalls affecting hundreds of thousands of Nissan crossovers.

The larger of the two involves the electrical system in 2008-2013 model year Rogue CUVs. In affected vehicles, a mixture of moisture and salt seeping in through the carpet on the driver's side could cause the harness connector to short, potentially causing a fire. The issue involves Nissan Rogues manufactured between March 7, 2007, and November 26, 2013, as well as examples of the 2014 Rogue Select manufactured between September 23, 2013, and July 2, 2014. All told, that comes to an estimated 468,815 units in the United States alone.

The second recall affects the relatively smaller quantity of 170,665 vehicles, made up of 2013-14 Nissan Pathfinder, 2014 Pathfinder Hybrid, 2013 Infiniti JX35, 2014 QX60 and 2014 QX60 Hybrid models. (The JX35 was recently relabeled as the QX60 under Infiniti's new nomenclature.) The issue affecting some of those vehicles revolves around a hood release cable that may not properly latch.

Nissan is notifying owners of the affected units to bring their vehicles in to have the wiring checked and to replace the harness connector and seal in the former case, and to have the hood release mechanism modified in the latter. All told, an estimated 639,480 vehicles are being recalled as part of the two campaigns.
