General Motors is again recalling Chevrolet Bolt models, because at least two cars are on fire.

This concerns a total of 69,000 electric cars worldwide, after 50,000 vehicles were recalled in November 2020.

The group announced on Friday that it had discovered a "rare manufacturing defect" in the electric cars.

This mistake could cause a fire.

General Motors says it will replace the batteries of the cars.

That is an expensive operation, but the owners do not have to pay for it.

Last week, General Motors warned owners of 2017, 2018 and 2019 Chevrolet Bolt models not to park their cars in garages or right next to buildings.

If the car caught fire, the damage would be limited that way.

The company also advised customers not to charge their cars overnight to prevent the vehicle from catching fire.

That advice still stands.
