NHTSA complaint #11655195

Owner complaint summary

Car has been brought to KIA for transmission issues multiple times and the associate tells me to just tighten the gas cap to get the light to go off. The car is not shifting properly and will "jump" or "lunge" forward while driving. I have noticed that the RPM's will jump and bounce around, seemingly down shifting, then shift again, and then down shift again, which causes jerking motion. The reason I initially took the vehicle in was for a "shake" or "wobble" when accelerating up a hill (semi steep incline) or at freeway speeds (55-70MPH). In these instances, the vehicle will have a hard time shifting and temporarily lose momentum causing concerns for me and other drivers on the road. The transmission light will go on and I call KIA to be told to tighten the gas cap. I recently brought it in for the third time and they diagnosed something different. I have mentioned the transmission each time, but they have focused on other items and not the transmission. I have had the shocks replaced, the tires replaced, alignment performed, and the problem still persist. However, the dealership will not look at the transmission and says that it is the other items, but the issue still remains after fixing the other items. The shock failure caused other items to wear out and the dealer should be on the hook for those items. I have brought the vehicle in dating to last year for the transmission issue with no help from the dealership. Please take action so that we don't lose our lives or put others at risk for injury.
