The recall covers some QX56 SUVs from 2013 and the QX80s from 2014. The company says inflators made by Takata Corp. were built with an incorrect outer baffle part. That can cause pressure to build up, and the inflators can rupture if driver's side air bags are deployed.

Nissan has no reports of injuries from the problem. It was discovered after General Motors recalled 33,000 Cruze compact cars for the same problem in June. The Infiniti recall is part of a larger global recall of 260,000 Nissans announced last week.

Takata says the recall only affects GM and Nissan vehicles and is separate from another one covering 8 million vehicles in US In that recall, prolonged exposure to high humidity can cause inflators to malfunction and explode with too much force. Safety advocates say four people have died due to that problem, which affects 10 different automakers.

Some automakers have limited their recalls to a small number of high-humidity areas, but lawmakers and others are demanding that recalls be expanded nationwide. Covered are cars made by Honda, Nissan, Chrysler, Ford, Mazda, Subaru, Mitsubishi, Toyota, BMW and General Motors.

The National Highway Traffic Safety Administration is investigating the humidity issue and could expand the size of the recall. Lawmakers say there are about 30 million vehicles on the road in US with potentially defective Takata air bags.

Nissan said in documents posted today by NHTSA that it asked Takata about the baffle problem after General Motors recalled 33,000 Chevrolet Cruze compacts in North America last June. GM said in documents that it also went to Takata after it was sued by someone who was injured by an exploding air bag.

Yesterday, US safety regulators ordered Takata to provide more information about potentially faulty air bags. The order made 36 separate requests for data on production mistakes, lawsuit settlements and reports of deaths or injuries that the Tokyo-based company has received. NHTSA also wants to know how many replacement parts Takata can make each day and what it has discussed with automakers and competitors.
