The latest recall by General Motors involves safety bugs pertaining to air bag software that has so far been linked to three injuries and one death.
General Motors Recalls 4m Vehicles over Safety
Although rare, it has been found that the vehicle’s diagnostic and sensing system, which controls the deployment of the air bag, can be triggered into a test mode, according to a statement by the company.
If the test mode is triggered, the air bags fail to inflate in the event of a crash and seat belts may also jam.
The problem became apparent in May when a 2014 Chevrolet Silverado crashed and its air bags failed to inflate.
GM and Delphi decided last week that they would recall the vehicles after testing the diagnostic modules.
In a statement, GM said that it would inform customers and update the air bag software free of charge. So far, dealers have gained access to the necessary updates for the software so they are able to repair the vehicles fast.
This was the second such recall by major US carmakers. Ford has already expanded its current recall from 900,000 vehicles to 2.4 million vehicles over problems arising from a malfunction on the door latch for 2012 to 2015 models.
For GM, the recall is equally large but rather than a mechanical change, its vehicles require a software update.
Vehicles that need an update range from the 2014 through to 2017 model years. In particular, recalled models are Chevrolet, GMC, Buick and Cadillac.
This recall was voluntary, unlike the highly popularized 2014 recall, which was necessitated by ignition switch issues and cost the company up to $2 billion in damage and litigation.
According to information on the National Highway Traffic Safety Administration, this latest recall by GM will affect up to 4.28 million cars globally with 3.6 million of them being from the US.
