I tow a caravanwith this car ona regular basis and use the cruise control on motorways at a steady 60mph. Up until recently no problems however when i try and use it now the cruise will set but then knocks itself out after about a minute or so. My localkindergarten (sorry dealership) have checked it out and i have the typical stock answer which is "couldnt find a fault with it sir" They spoke direct with Kia who say the cruise isnt designed to be used when towing as the gearbox oil will overheat and then cuts out the cruise, if that the case says i then how come its worked for the past 11 months, You have just been luck sir!!!
Anyone else experienced this or is experiencing this and if so any joy in getting it sorted.
