General Motors Recalls Four Million Vehicles

General Motors is recalling four million vehicles worldwide to fix a software defect that has been linked to at least one death.

The company said the move was necessary to fix an airbag software defect in certain models.

GM says the the fault is rare, but car's computers can go into test mode and the front airbags will not inflate in a crash,in "rare circumstances when a crash is preceded by a specific event impacting vehicle dynamics."

It said the seatbelts may also not function.

The Detroit carmaker said the issue has been linked to one death and three injuries and it will notify customers and update the software for free.

It is unclear at this stage whether any GM vehicles are affected in the UK.

GM owns Vauxhall motors.

But it said no Vauxhall cars were affected by the fault.

The vehicles being recalled are:

:: 2014-2016 Buick LaCrosse, Chevrolet SS and Spark EV

:: 2014-2017 Buick Encore, GMC Sierra and Chevrolet Corvette, Trax, Caprice and Silverado

:: 2015-2017 Chevrolet Tahoe, Suburban and Silverado HD, GMC Yukon, Yukon XL, Sierra HD, Cadillac Escalade and Escalade ESV

General Motors Co said the recall of newer trucks, cars and SUVs from the 2014-2017 model years would not have a material impact on its financial results.
