(Reuters) - U.S. regulators on Friday announced a new recall of about 5 million vehicles with potentially defective Takata Corp air bags, covering some automakers not previously affected by one of the biggest auto safety recalls in U.S. history.

The new action brings to 28 million the number of Takata air bag inflators recalled and increases the number of vehicles affected in the United States to as many as 24 million, the National Highway Traffic Safety Administration (NHTSA) said.

Friday's move was prompted in part by the death of the driver of a Ford Motor Co pickup truck last month, as well as new tests conducted on suspected faulty air bags.

Automakers affected for the first time include Volkswagen and its Audi unit and Daimler's Mercedes-Benz unit.

"This is a massive safety crisis," NHTSA spokesman Gordon Trowbridge told reporters.

NHTSA in November said tens of millions of additional vehicles with inflators containing ammonium nitrate will be recalled by 2018 unless Takata can prove that they are safe.

The Dec. 22 death of a Georgia man in South Carolina was the 10th worldwide linked with Takata's air bag inflators, NHTSA said. It was also the first to occur in a vehicle that was not made by Honda Motor Co.

The 5 million vehicles covered by the new recall include about 1 million with inflators similar to those installed on the Ford Ranger pickup, NHTSA said.

About 4 million other vehicles will be recalled due to additional testing on Takata air bags, including vehicles from Honda, VW and other automakers, the safety agency said.

Twelve major automakers have previously recalled more than 23 million Takata air bag inflators in more than 19 million vehicles in one of the largest and most complex safety recalls in U.S. automotive history.

NHTSA did not immediately say how many of the 5 million vehicles being recalled Friday may have been covered by previous recalls.

Takata's inflators can explode with too much force and spray metal shrapnel into vehicle passenger compartments and are linked to more than 100 U.S. injuries.

A South Carolina attorney said in a complaint filed with NHTSA that his client was killed when "metal from the inflator canister exploded penetrating my client's neck resulting in death."

The attorney, Andrew Creech, said in the complaint, "There is no doubt airbag shrap (shrapnel) metal killed my client, as this has been confirmed by death certificate and autopsy report."

The man killed in the 2006 Ford Ranger struck a cow that was in the road, Creech's report to NHTSA said.

Creech was not available for comment on Friday.

In November, Takata agreed to pay a $70 million fine for safety violations and could face deferred penalties of up to $130 million under a NHTSA settlement.

NHTSA in December named a former Justice Department official as a monitor to help regulators oversee the massive recalls.

The Ford death is the first reported since the July crash of a 2001 Honda Accord coupe that killed a 13-year-old near Pittsburgh, Pennsylvania.
