WASHINGTON — Nissan North America is recalling 625,000 2013-'15 Nissan Altima sedans because the hood could unexpectedly open while driving, according to the National Highway Traffic Safety Administration.
"In the affected vehicles, the secondary hood latch may bind and remain in the unlatched position when the hood is closed," said NHTSA in its recall summary. "If the primary latch is inadvertently released and the secondary latch is not engaged, the hood could unexpectedly open while driving, increasing the risk of a vehicle crash."
This is an expansion of an October 2014 recall involving 220,423 2013 Altimas.
Nissan told federal safety regulators it is "continuing to investigate the root cause of this issue."
The expanded recall involves vehicles built from March 1, 2013 to December 31, 2014.
"Nissan tentatively concludes that vehicles manufactured after December 31, 2014 are not affected," the company told NHTSA.
Nissan is not aware of any accidents, injuries or fatalities linked to the recall, wrote Nissan spokesman Steve Yaegar in response to a query from Edmunds.
A remedy for the problem has not been determined.
"Nissan 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," the company told NHTSA.
Nissan said it planned to notify dealers about the expanded recall on February 27. A date has not been set for the recall.
"If a permanent remedy is not available, Nissan will begin issuing interim owner notifications within 60 days," the company said.
Owners can contact Nissan customer service at 1-800-647-7261.
Edmunds says: It's best for owners of these cars to stay in touch with their dealers on next steps while Nissan sorts everything out.
