If you drive a Honda car, here’s what to worry about

Honda is recalling 4.5 million vehicles worldwide in the wake of the faulty airbag issues in some of its vehicles. This isn’t something new as Honda has earlier recalled 20 millions vehicles on the same Takata-made airbags defect.

A news report by AFP says, the defect thought to be associated with a chemical propellant that helps inflate the airbags can cause them to deploy with explosive force, sending metal shrapnel hurtling toward drivers and passengers.

The most recent confirmed victim was a woman in Los Angeles who died last year after the defective inflator in a 2001 Honda Civic ruptured, firing metal shards at her.

"Like other carmakers, we are investigating vehicles on the markin connection with this issue, and we found that some inflators have uneven gas density, which we worry could do some harm," a Honda spokesman told the agnecy.

"It is a preventive measure and unlike other normal recalls we are not waiting for the full results of the research," he added.

Honda's biggest domestic rivals Toyota and Nissan last month expanded their huge global recalls, with worldwide totals now well into the tens of millions.

Tokyo-based Takata has been under fire over the crisis, as it faces lawsuits and regulatory probes into accusations that it knew about the problem and concealed the dangers.

Kevin Kennedy, executive vice president at Takata's US arm TK Holdings, recently told US lawmakers that the company -- one of the world's biggest airbag suppliers -- is still searching for the main cause of the deadly explosions.

But he said Takata's investigation was already focused on the possible instability of the main ammonium nitrate propellant in airbag inflators, particularly in humid environments.

Ten global automakers, also including General Motors and Germany's BMW, are being forced to recall some 34 million cars inside the United States alone to replace the inflators -- the biggest recall in US history.

US safety regulators began fining Takata $14,000 a day in February to pressure it to supply documentation on internal probes into airbag issues dating back more than a decade.

Research "seems to indicate that ammonium nitrate is certainly a factor in the inflator ruptures," Kennedy conceded last month. But he added that there are "many other factors".

Takata and other parts makers have stepped up production of replacement airbags and inflators to reduce the dangers, but many of those from Takata still use ammonium nitrate.
