Ive noticed this since day one and never thought anything of it till I had the level and tires installed, the tech was questioning the noise but never dug into it.
I go weekly. Granted I live 100 miles away but we go nearly every Sunday after church. With my level and tires it’s always an edgy trip as I get home usually with 50-80 left. Before you say it’s the level and tires it was the same on the stock setup, but the i4 trip can avg at the right time...
In regards to all the ones saying its dangerous and scary have never been around a Mercedes S Class, or Lexus ES. Those cars are dead silent when reversing, the engines dont make even a whisper
