Japanese auto giant Toyota is recalling 6.4 million vehicles globally over five separate issues.
Some 3.5 million vehicles are being recalled to replace a spiral cable attached to the driver’s side airbag.
It may be damaged when the steering wheel is turned and result in the airbag not being deployed in a crash.
Other issues include problems with seat rails, steering columns, windshield wipers and a glitch with the engine starters that poses a fire risk.
Toyota said it was not aware of any vehicle crashes, injuries or fatalities caused by these conditions.
However, it said it had received two reports of fires in connection with the engine starter problem.
The carmaker said that “due to inefficiencies in the design of the starter motor relays, metallic particles might accumulate on the contacts within the relay.”
It said that if the relays continued to be used, the particles could come off and enter the relay’s circuitry and in the “worst case, this could lead to the starter relays catching fire.”
Approximately 2.32 million vehicles have also been recalled over problems with the seat rails, some 760,000 because of a potential defect with the steering column bracket, and nearly 160,000 to replace the windscreen wiper motors.
