I'm a new owner of Clarity and have been driving my car for over a week and love it. I notice that there is a noise when accelerate or decelerate the car. It sounds like an ambulance in a distance. It is not very loud but definitely noticeable. At the beginning, I was confused why there was always an emergency vehicle when I exit the highway. I thought it was the Acoustic Vehicle Alerting System, but the sound appears at higher speeds than 12 mph, I don't know exactly at what speed it start to appear though. I also noticed that I can't hear it when the windows is open. Not sure whether it is because of the louder road noise. Could it be the wind noise or engine noise? Has anyone noticed the same noise? Is it just the AVAS at higher speeds? Thank you.
