2025 Kia Sorento: hesitation when accelerating

Filed Jul 1, 2026 · Transmission · OH

The transmission is not shifting gears correctly. The engine revs loudly and hesitates for a few seconds before shifting. There were no warning lamps. The vehicle has not been inspected yet. This causes a dangerous situation when driving and accelerating in traffic.

The DCT transmission causes significant hesitation at slow speeds or starting from a stop. This often leaves the driver and it’s occupants in a vulnerable position if the car hesitates when trying to navigate through traffic. I have taken it to the dealership and they stated that nothing is wrong with it, However, in reviewing online forums, it is obviously a significant concern.

My vehicle has an ongoing acceleration problem that feels like the engine and transmission are not communicating correctly. There are times when the vehicle will not accelerate even though the RPMs increase. Instead of picking up speed, it feels like the engine is pulling the vehicle back. This creates hesitation and uncertainty about whether the car will respond when I press the accelerator. This happens most noticeably at lower speeds (around 30–40 mph, often near 30 mph), where the RPMs may rise on their own even if I am maintaining steady pressure on the gas pedal. It also occurs when I need to accelerate quickly — such as merging onto the freeway or joining the flow of traffic — and the vehicle feels like it resists gaining speed. Even when I press the pedal gradually and correctly, the vehicle struggles to accelerate and the engine revs without the car moving forward as it should. I reported this to the dealership. They ran diagnostics and told me no issues were detected. They also stated they cannot take action unless they can re-create the problem themselves. Because this does not happen every time, recreating it on command is very unlikely, leaving me without a solution. This is a safety concern because hesitation or failure to accelerate properly during merging or crossing traffic increases the risk of collisions. The problem remains unresolved.

Our 2025 Kia Sorento has exhibited several issues with shifting into gears especially from 1-2 gear there is hesitation, hard shifting, where it has delayed engagement, rough or jerky shifts, and a feeling of power loss while driving. It has a hard time getting into 3rd gear and just stalls, dragging at 1st/2nd when attempting to accelerate and coming down from 4th gear back into 2nd and 3rd. A "check transmission' warning light has appeared on the dashboard. This is teh second time we have had this issue. The car only has 16K miles on it, we have had it for 12 months exactly now and only drive it locally.

While traveling to VA from TX, [XXX] and on [XXX] the vehicle hesitated to accelerate multiple times. Some were from a complete stop, and other times it occurred when accelerating to merge on the highway. On [XXX], I pulled out of a driveway onto a very busy road and upon increasing pressure on the gas, the vehicle shook (similar to the behavior of a manual when letting up off the clutch and not applying even pressure to the gas. Due to the vehicle's hesitation, I as almost hit by a large truck traveling on my exact path. This was the sole instance that warranted a call to Kia Corporate, as I feel the issue is a significant safety concern. I placed the vehicle in service 11-12 JUN and the attached receipt highlights that the dealer was unable to replicate the issue. As of 16 JUN, the vehicle is still exhibiting the same issue intermittently, along with the break pedal popping when ascending or descending on a hill/ramp.
