I have a 1 year old Kia Sportage that seems to vibrate and lose power at around 1200 rpm and 40 mph (and general range) especially on a grade. It seems to do the same thing at 2000 rpm at 70mph and won’t speed up despite attempts at acceleration.
Good for you? If you think this is a problem take it to your local dealer, this car is still under warranty.
