one of the more annoying characteristics I've foudn with my car is its non-linear response to the pressing of the throttle pedal.
In fact, non just non-linear, but non-predictable.
Sometimes nothing happens with the initial half travel of the pedal, which can get dangerous when overtaking or crossing intersections. Not much response until you floor the pedal, which is not how it was on the Highlander AWD.
The Highlander responded well to light pressing of the accelerator.
