Nissan is joining the recall party, expanding one for its Altima sedan in North America because of issues with hood latches.

The problem concerns a secondary latch designed to hold on to the hood in case the main latch doesn't work, according to The Next Digit. The Japanese automaker said there is a good chance that second latches in models made from 2013 and 2015 may not hold.

About 878,000 vehicles are covered in the recall, with the original recall from October covering close to 238,000 sedans in North America and this week's covering 640,000 cars in the U.S. and Canada.

Nissan has yet to find the root cause of the issue or its solution, nor has it determined if it needs to expand the recall again, Reuters reported.

"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 in an email on Friday.

The Altima is one of Nissan's top selling cars, accounting for one-fourth of the company's sales in the U.S., Reuters reported.

The automaker told the National Highway Traffic Safety Administration that it will "implement an interim procedure to inspect and lubricate the secondary hood latch assembly on all subject vehicles manufactured prior to December 31, 2014 in dealer inventory prior to retail sale."

Nissan is expanding the recall in compliance with rules established by the NHTSA, The Next Digit reported.  

The company has yet to receive reports of injuries or crashes related to the issue.
