Daimler is to recall around 75,000 Mercedes-Benz cars in the UK and one million cars worldwide after around 50 fires were reported.
No injuries or deaths have yet been recorded.
The fault is reported to affect the fuse in some of its A, B, C, and E-class cars as well as its CLA, GLA and GLC vehicles and could cause them to overheat when starting the car.
A fix has been implemented in the production of new vehicles and cars already currently on dealer forecourts.
