Just under 80 cars are included in the campaign, which relates to an issue with the passenger seat occupant detection.
Mercedes-Benz has recalled the 2018 B-Class and CLA over concerns about an issue with the automatic occupant detection system in the front passenger seat.
If a child seat is installed facing backwards in the passenger seat, it's possible the airbag might not automatically turn off. If an affected vehicle is involved in a crash, and the driver has a child restraint in the front passenger seat, there's a risk the airbag will fire and put the child in danger of injury.
A total of 78 cars sold between March 1, 2018 and May 2, 2018 are affected by the campaign – a VIN list is attached here.
Mercedes will contact owners of the affected vehicles and advise them to organise a free fix with their nearest dealership.
