DETROIT (AP) — Nissan is recalling 625,000 more cars in the U.S. as part of a growing problem with faulty latches that can allow hoods to fly open while cars are moving.

The latest recall covers Altima midsize cars from the 2013 through 2015 model years. It brings the total number of vehicles recalled for the problem to nearly 1.1 million.

Nissan says in government documents that if the main hood latch isn't fastened, the secondary latch may not hold the hood closed as designed.

Nissan previously recalled 238,000 Altimas from 2013 for the same problem, as well as 216,000 Nissan Pathfinders from 2013 and 2014, Infiniti JX35s from 2013 and QX60s from 2014.

The company says it's still investigating and could recall more vehicles.

Nissan hasn't finalized a fix for the problem.
