Driving 2018 Stelvio with 17K on returning from a long trip here is what happened: With ACC on driving into mist, it went off (ACC not available), a few minutes later cruise when off. Went through a rain storm (don't know if that had anything to do with it, but), next got warning light on dash that left signal light was out, then right, then running lights, brake lights, repeated warnings. For next few hundred miles no cruise and continued warning lights. But visably checked signal lights and they were working. Went to dealer and they determined there was a fault of some kind in one of the tail lights? They had to order part. Left dealer and noticed the lane change buzzer not working. Finally, just as arrived home a warning light on dash that the "electronic throtle control service required". Thankfully the headligts were working and it seems to be running normal. But, Now I am skeptical that the dealer's "fix" is what is needed. Advice and information appreciated.
