2016 Kia Soul: hesitation when accelerating

Filed Feb 7, 2026 · Transmission · GA

I paid almost 3,500 dollars and Kia kept my car two months and I’m still having transmission issues and now they are asking for service receipts. After I picked up my vehicle from the original transmission repair I was back in less than 7 days because transmission was roughly jumping in gear and shifting horribly with burning smell. The technician noticed the problem and immediately took my car to the back but they kept my car another 30 days saying that they did an update and now I’m stuck suffering with a struggling transmission. My mpg has drastically dropped on this vehicle to a 9.6 and that is not normal. I paid cash and Kia need to help me in any way. They are trying to wait until the 12,000 mile warranty runs out and leave me stuck and that’s not fair when I’ve been complaining since I picked up the car the second time but they won’t assist me now. My Vehicle experiences delayed transmission engagement, RPM increases without acceleration, hesitation, and loss of fuel economy. Dealer refuses diagnosis unless complete failure occurs. This creates unpredictable vehicle response and loss of power concerns. Transmission hard shifts and jerks violently during gear changes and acceleration, causing loss of smooth power delivery and unsafe vehicle behavior.
