Taken my 2019 (< 28,000 miles) vehicle in 3-4 times now for crackling noises in audio system. Each time a fix is promised. Each time the crackling got 'worse'! I can't tell you how frustrating it is to be taking in a brand new car. What is interesting is even when the radio is off, I hear the crackling - but less frequently and not as loud (and my phone is not connected to the system). Why can't the whole system be replaced with a system that has proven to be sound (without recorded problems)?
