Nissan is recalling 640,000 more cars in the US and Canada to fix a growing problem with faulty latches that can allow hoods to fly open while cars are being driven.

The latest recall covers Altima midsize sedans from the 2013 through 2015 model years, bringing the total number of Nissan and Infiniti vehicles recalled for the problem to nearly 1.1 million worldwide.

In documents posted yesterday by the US National Highway Traffic Safety Administration, Nissan said that if the main latch isn't fastened, the secondary latch may not hold the hood closed as designed.

Yesterday's recall covers Altimas built from March 1, 2013 to December 31, 2014. In October last year, Nissan recalled 238,000 Altimas from the 2013 model year for the same problem.

Those were built from March 6, 2012 to February 28, 2013. Also, in January, the company recalled 216,000 Nissan Pathfinder SUVs from 2013 and 2014, Infiniti JX35s from 2013 and QX60s from 2014 for the same problem.

Nissan has received no reports of crashes or injuries caused by the problem, spokesman Steve Yaeger said yesterday.

Dealers will modify the latch lever, as well as clean and lubricate the secondary latch joint. The latch assembly could be replaced.

The problem was discovered when Nissan received reports of a small number of hoods coming open and damaging the cars.-Reuters
