Nissan has expanded a recall of their Altima sedans to include 640,000 more cars in the U.S. and Canada over latches that could be faulty and cause hoods to fly up while driving, according to USAToday.

Nissan is adding 2013-2015 Altima models, bringing the total number of Nissan and Infiniti models recalled to about 1.1 million.

Nissan says the problem is with its dual latching system, they told the National Highway Traffic Safety Administration. Like most cars, the recalled cars have a latching system that allows drivers to pop the hood, but a second latch needs to be activated before it will actually raise up.

This recall says the secondary latch might not keep the hood closed if the primary latch is not fastened properly. That could cause the hood to fly up while driving.

The latest recall covers Nissan Altimas built between March 1, 2013, and Dec. 31, 2014. According to The Associated Press, Nissan recalled 238,000 Altimas from the 2013 model year for the same problem. Then, in January, Nissan added 216,000 Pathfinder SUVs from 2013 and 2014, Infiniti JX35s from 2013 and QX60s from 2014 to the recall for the same problem.

Nissan is aware of reports where drivers' hoods have popped up while driving, but no injuries or crashes have been reported.

Nissan will fix the affected cars by either replacing the latch mechanism or modifying the latch lever. They will also clean the secondary latch joint. Nissan tells drivers of the affected cars to make sure their hood is latched and locked if they cannot yet make it to a dealer to have their cars repaired.

"Altima drivers can be sure their hood will not fly up as long as they don't pull the primary hood release while driving or leave the primary hood release undone prior to driving," a Nissan spokesman said.
