I didn’t have this problem until I updated my software last month at the dealership. Here is the symptom: i start my car with any charge level, regardless full or not. I drive at EV. I don’t brake at full battery level. The angry bee sound starts to be noticeable at 20mph and totally depends car speed. The higher the speed, the louder the sound, regardless whether I press my gas pedal or not. There is no sound at full stop. It will go away after about 10 minutes of driving and will repeat next time I start my car. I have also notices the estimated mileage reduced during these period. It is reproducible every single time. It is quite annoying and totally detroys the fun of EV driving. Any thoughts?
