2023 Kia Sportage: jerking or lurching

Filed May 28, 2026 · Visibility · MA

I had gotten my windshield replaced by safelite last year. On a cold day while driving to work, I went to adjust my rearview mirror and the rearview mirror came off from the windshield. It completely detached. I was adjusting it as I would any other time I adjusted the rear view mirror. This obviously left me in a lurch because I had to go to work. So I drove without a rear view mirror until I could get a replacement after the work day. This is obviously a dangerous situation to be in. I reached out to safelite because they have a lifetime warranty. They informed me that they will not cover replacement because a small piece of glass came off of the windshield which according to them means it must have been a result of force.

Purchased the vehicle 2nd hand January 29th 2025. Since then she has been in and out of multiple shops including Kia. Check engine light, loss of power on fwy, shifting/brake changes from a stop. From jerking, lunging, studder, taking off fast, not wanting to go at all. I was on these dips that I encounter almost daily and the collision warning went off. There wasnt anything in front of me. 2 weeks later I was cut off and had to swerve to avoid. Collision warning DID NOT go off. Driving on the fwy and the gas pedal pulled away from my foot as if it was accelerating. Kia has done a hard carbon, changed all fuel injectors. Last time they stated there was a factory defect with the rotors, changed all 4 rotors. Still she drives like this. Carmax, Kia and Daniels Tires NO ONE can tell me what is wrong! I have driven a 2024 same make and model and the car drove beautifully. Something is wrong with my particular vehicle. This is becoming frustrating. Please help. I drive often, I hike a lot. We are always on winding roads. I can't afford to sell it as I still owe. I love the vehicle, aside from this, like I'm just waiting for disaster to occur. Miles started at 14.5k and it's now 33k. Speeds have been anywhere from a complete stop to go and fwy speeds of 55 to 80.

The issue appears to involve the CVT (Continuously Variable Transmission) system or the transmission fluid/lubricant pump. The vehicle jerks or hesitates when accelerating from a stop, as if struggling to shift properly. The check engine light comes on repeatedly. This issue is ongoing, and the vehicle is available for inspection upon request. The jerking and hesitation when trying to drive, especially from a stop or when merging into traffic, poses a safety risk to myself and others. The delayed or unpredictable response could easily lead to an accident in high-traffic areas, intersections, or when making turns. Yes. The issue has been observed multiple times. The check engine light has returned even after replacing the O2 sensors, and a trusted mechanic believes the problem may be transmission-related. However, the Kia dealership claims there are no active recalls tied to my VIN, even though publicly available information lists powertrain- and fluid pump-related recalls for my vehicle's year and model. The vehicle has not yet been inspected by Kia corporate. I reached out to the local dealer, who denied any applicable recall. I am submitting this complaint in hopes of an official review and inspection by the manufacturer or the federal safety agency to determine if the issue qualifies for safety recall intervention. Yes. The check engine light first appeared months ago, which led to replacement of the O2 sensors. Shortly after the replacement, the light returned, and the car began jerking while trying to drive or accelerate from a stop. These symptoms have persisted and appear to be worsening.

A few months after I got the car all of the warning lights randomly came on and I had to turn jt off and on and they went away. Since then around Nov 22 it has happened about 25 times or more and is happening more frequently lately. I called kia and they said they hadn't heard anything yet bc of it being so new. Also the brake assist for Collison is VERY dangerous. You can be a car length and more away and it will take the brake out from my foot and slam on the brakes and about throw me through the windshield with my seat belt on. This has happened too many times and has hurt my chest. I turned it off and it has still done it. Another thing, the lane assistance tries to take the wheel away from you and will jerk the car one way or the other which is scary. Please look into these!!

The car is currently in the shop at Jim Shorkey Gainesville Kia and is available for inspection. They have contacted me to tell me the transmission/engine failed. I was driving on interstate when I suddenly lost the ability to accelerate and was forced to get off of the highway. After coming to a complete stop I pressed on the gas pedal but the car would still not accelerate. I tried putting into park and back into drive and that did not work. I tried putting it into manual mode and it did go forward but every gear change was loud, jerky, and rough. I was able to make to my next complete stop in a left turning lane to cross a two lane busy highway that is coming downhill towards me at an intersection that does not have a traffic signal. However the car was stuck in gear 5. I was the first car in line. At this point I put other cars in danger as they swerved back into the high way to get around me into the intersection to make that left turn across busy highway. I turned the car completely off and after a minute turned it back on. I put in drive, waited until I couldn't see any cars coming down the hill and I pressed the gas pedal to test. It jerked forward and I managed to get across the highway as it shifted into the second gear it jerked violently and made a loud popping noise and there after every single gear change was loud and jerky. Thank God I did not lose the ability to accelerate in that left turn because those cars are coming at 70+ miles per hour Down that hill or my family would have been t-boned on their passenger side. I am also lucky that I was able to get off the nearest exit when they problem originally happened as I was going downhill on the interstate and the next exit was very close so my momentum got me there. I lost the ability to control the vehicle as I ordinarily would putting myself, my family, and other motorists in danger had we not been able to get off on the exit or make it through that left turn.
