The kia app is cheep nasty ,last night i had msgs on it ,engine still running do you want valet mode ????. So i went to check ,wasnt running ,dont think it will lock if engine running. I had problem with rear sensors ,but, i have learnt all settings now ,so should function now, ive taught myself all settings in car which is quite extensive , voice cammands work but are not extensive, tomorrow i will use cruse control adaptive , lane keep & lane assist. I dont like parking with all round view ,im happy use big wing mirrors, i do love the car though ,only few odd bits.
