I really like my new car but do not know if this decelerating is normal? It does it at all speeds but is most noticeable at 40 and below. Just take your foot off the accelerator and there is something slowing the vehicle down like a Jake brake in a diesel truck feel. Car does not coast. It coasts if you throw it to Neutral so I know it is not braking. The eco light stays on and the dealer says it is operating as designed which is an insult to my intelligence. Does anyone else feel this and is it normal?
