I just purchaced my first KIA, FORTE. Great car so far except for a minor, intermitted shifting problem. Whe car is up to normal temp, driving for at least a half hour, the 2-3 & 3-4 upshift hits hard, slight engine RPM surge. This has happened about 10 times.
It has been doing it since new. Now has 1500 miles on it. Dealer says they will check it out on our first service.
Has any one else having this problem?
