Hi, in my kia ceed 2013 my start stop hasnt been working for ages now since September 2019, when i stop it just says auto stop deactivated. I do alot of miles a day around 70 miles on the motorway. My family also has a 2017 ceed exactly the same model of engine 1.6 petrol and a higher trim level with more power consuming infotainment and they travel less miles than me in the week and their start stop works mostly all the time and if it does not work on their kia it says autostop conditions not met whereas mine just says deactivated? Kia said the battery might need to be charged and they recommend i buy a trickle charger or i pay them £20 to charge it but I brought a trickle charger from halfords and the battery appeared to be charged within 5 minutes, so somethings not right. But they said the battery appears to be in good health, it has no trouble starting the car, odd.
