US to probe if Nissan failed in air-bag fix

New York

US regulators are looking into whether a recall last year by Nissan Motor Co, Japan's second-largest automaker, failed to fix a flaw in the air-bag control systems on almost one million vehicles.

The National Highway Traffic Safety Administration (NHTSA) opened a query March 18, citing 124 complaints filed by motorists after the recall began last April, according to a notice posted on the regulator's website. Some drivers alleged the flaw persists after multiple repairs by dealers.
