Cars are safe to drive despite warning of 'inadvertent deployment'.
Mercedes is recalling 400,000 cars in the UK because the airbags might accidentally go off.
The problem affects around 1.3m cars across the world, although Mercedes has not yet confirmed the full numbers.
The recall covers 2012-18 model year A, B, C, and E-Class cars, as well as CLA, GLA and GLC models.
‘If the steering column module clock spring is broken and the wiring components are not sufficiently earthed, this could lead to an electrostatic discharge which could inadvertently deploy the driver's airbag,’ said Mercedes.
The company says that the cars are safe to drive, but if the airbag warning light comes on drivers should call roadside assistance or their nearest Mercedes dealership.
The German manufacturer will contact owners of affected cars to arrange for remedial work to be carried out, which should take an hour.
