The largest number of Sorento customers - 3,500 - are being contacted regarding the possibility of the alternator pulley seizing and causing the alternator drive belt to be displaced. This can result in increased steering and braking effort being required.
In all cases the pulley will be replaced at no cost to the customer. There have been no recorded instances of the alternator pulley seizing on UK vehicles.
In the second case, 1,152 Sorento customers are being contacted for their automatic transmissions to be replaced because a retaining ring inside the transmission may come loose.
Although no cases have been reported in the UK, Kia are taking the action because it would be possible for a vehicle to roll forward whilst in reverse gear.
The automatic transmissions are being replaced free of charge.
