Nissan is recalling about 323,000 SUVs because of hoods that can open unexpectedly.

Owners of the affected vehicles should be notified by mail starting July 18. A second letter will be sent when a repair has been developed.

The recall affects 2013 through 2016 Pathfinder SUVs sold in the US with hoods that can unexpectedly fly open and block the driver’s view. Dust and dirt that can collect on the secondary hood latch are believed to be the cause of the malfunction, even when the hood is closed.

The company is working on a repair.
