Toyota has recalled 2.27 million vehicles globally over a defect that suggested airbags could fail in a crash and could also pose a fire risk, dealing another blow to the Japanese giant's safety record.
The world's biggest carmaker said the latest call-back involved 20 models, including its Corolla and Yaris sedans and Noah mini-van, and covered about 1.62 million cars overseas and 650,000 in Japan.
Some of the overseas cars were already included in a recall last year, but the airbag inflator was not replaced, Toyota said.
"The involved vehicles were equipped with front passenger airbag inflators which could have been assembled with improperly manufactured propellant wafers," it said. "[That] could cause the inflator to rupture and the front passenger airbag to deploy abnormally in the event of a crash."
A company spokesman in Tokyo said it had received a complaint from a Japanese customer who said his passenger seat was burned from the defect. No serious injuries or accidents had been reported, he added.
In April, Toyota recalled 6.39 million vehicles globally over a string of problems, and another 520,000 last month, mostly in North America, over issues including cable corrosion that could cause unused spare tyres to fall off the vehicle.
In February, it recalled 1.9 million units of its signature Prius hybrid cars, after recalling millions of other models in recent years over a possible fire risk and other safety issues.
