Continental Automotive Systems has said it supplied potentially defective air bag control units to five million vehicles used by Honda, Fiat Chrysler, Mercedes-Benz, and three other manufacturers built over a five-year period worldwide, widening an air bag safety crisis.
Continental Automotive, a unit of Germany-based Continental, told the US National Highway Traffic Safety Administration that electronic systems built from 2006 to 2010 and used in five million vehicles may fail and air bags may not deploy in a crash or may inadvertently deploy without warning.
Continental spokeswoman Mary Arraf said the recall involved between 1.5 million and two million vehicles in the United States.
Honda said it is recalling 341,000 Accord models from 2008-2010 to replace control units linked to failures in Continental systems. At least two injuries are attributed to the defect.
Honda said it has received 1,575 warranty claims, 83 field reports and two confirmed injuries related to the defect.
It also said there have been 74 injury allegations related to airbags that did not deploy but those are not confirmed.
In one case, a parent in Belleview, Florida, filed a complaint that their son was injured driving their 2008 Accord last March after running into a concrete block wall at about 80kph and the airbags failed to deploy, according to NHTSA records.
Honda told its dealers that replacement parts are in very short supply and can only be ordered for vehicles with crash damage or with airbag issues.
Honda will not have enough parts for replacement for all vehicles until autumn.
Fiat Chrysler said it is recalling 112,000 US vehicles for the same issue, including the 2009 Dodge Journey, 2008-2009 Dodge Grand Caravan and Chrysler Town and Country and 2009 Volkswagen Routan that it had assembled for the German carmaker.
Fiat Chrysler has reports of as many as 25 inadvertent air bag deployments.
Continental told the NHTSA the callback would also involve vehicles built by Volvo Trucks North America and Mazda Motor Corp.
Mazda was aware of Continental's recall and investigating and VW did not know how many Chrysler-built Routan minivans are involved, according to company spokespeople.
This is the latest large-scale US recall related to air bag problems.
To date, 14 car manufacturers have recalled about 25 million vehicles for air bag inflators made by Takata that could rupture, emitting potentially deadly metal fragments.
They are linked to 10 deaths and more than 100 injuries.
NHTSA said tens of millions of other vehicles with Takata airbags will likely need to be recalled eventually.
