This may just be a case of crappy Drive by Wire ecu programming. I suspect you just didn’t notice until you got comfortable in your car.
I know 2006+ Civics are like this also, Step on the gas and there is a definite time lag before the computer accepts and implements this driver input.
It really bothers me for some reason when there is no direct cable connection from the gas pedal to the throttle body. I know that higher performance cars don’t have this lag issue.. but it still bothers me.
