Anyone can launch a law suit, but what matters is whether he can prevail in his complaint. I am averaging 46.5 mpg here in Northern NJ back roads, my average speed is about 37 mph. I did notice mileage drop when I purposely under inflated my rear tire by one psig, i.e. from 32 to 31. That was my attempt to soften the bouncy rear end. I think the solution is to instal F-Sport anti sway bar. But the mileage went right up when I return to specified inflation.
