2023 Kia Sorento: jerking or lurching

Filed Sep 9, 2026 · Engine · TX

My 2023 Kia Sorento has experienced repeated failures involving the engine, transmission/powertrain, and electrical wiring system. The vehicle has been inspected and repaired multiple times by authorized Kia dealerships, including Kia of Round Rock and Clay Cooley Kia in Irving, and the repair history and vehicle are available for inspection upon request. The most serious incident occurred on XXX, while I was driving on the [XXX]. The vehicle suddenly lost acceleration, began smoking, and experienced a catastrophic engine-related failure, creating a serious safety concern while I was traveling on a high-speed roadway. The vehicle had to be towed to Clay Cooley Kia, where it remained for approximately three months and the engine and related components were replaced. After receiving the vehicle back on XXX, a significant oil leak developed approximately five days later. The vehicle was returned for service, the problem was confirmed, and it ultimately required a transmission replacement. On approximately XXX, multiple/all dashboard warning lights illuminated, and Kia subsequently replaced the wiring harness. The vehicle continued to experience problems and was towed to Kia again. In XXX, Kia determined that another transmission replacement was necessary. The vehicle has now had three transmissions associated with it, in addition to the replacement engine and wiring harness. XXX, the vehicle is still malfunctioning despite being on its third transmission. Current symptoms include the RPMs suddenly surging/revving higher than expected, jerking while driving, and a noticeable delay between pressing the accelerator and the vehicle accelerating. These symptoms create a safety concern because I cannot confidently predict how the vehicle will respond when accelerating, merging into traffic, crossing an intersection, or traveling at highway speeds. I am concerned that the repeated engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2023 Kia Sorento with approx 60k, purchased new from New Pot Richey Kia. Approx 7 days ago, while driving home from dropping my son at school, my transmission system error warning came on as well as my check engine light. My RPM'S would increased without corresponding acceleration, which meant my transmission, was slipping. I was also experiencing jerking during shifting. In addition to that, my car would hesitate before moving. And I would also experience a slight vibrations at low speeds. All of this would make me feel unsafe when driving my car.

The car is accelerating without anyone pressing down on the gas, not accelerating when our foot is on the gas, jerking unexplainably and the emergency brake warning is coming on when it has not been employed.

On [XXX] while driving and in the process of changing lanes, as I accelerated on the brakes, my Vehicle gave a sudden jerk, at first I figured it was due to the road being wet, but on [XXX] while driving to NYC on [XXX] as we all know we all have to keep up the speed, once again during accelerating my vehicle repeated the same sudden jerk and continue for most of my ride, I brought into KIA on [XXX] with the end result being they did not find this issue, as well as my ongoing issue of my engine light that has been coming on and off for about 5 months now. I do believe my vehicle is having some kind of issue with the transmission and gears are not kicking in during the acceleration process may I add this is on the highway. My vehicle is a 2023 which I purchased in Aug of 2023 and have been in the dealership for shaking during braking engine light on and now gear delay with no resolution to all issues, I will be contacting the Manufactured as my next step in the horrible processes.
