2023 Kia Sorento Hybrid Transmission and drivetrain Problems

“Critical Issue: Gasoline leaks into engine. That causes increasing engine oil level significantly and mixed with engine oil. I dropped off me car (mileage: 11731) at Kia Pro in Glendale, CA on 5/1/2025 as soon as I confirmed that engine oil level exceeds the maximum (twice of max) and smelled Gasoline from the dipstick. The service advisor and a tech confirmed that the excessive engine oil level and gasoline smell. However, they refused to repair it under warranty because they don't see any physical leaks and error codes. …”

“The contact owns a 2023 Kia Sorento. The contact stated that while stopped at a light or making a left or right turn, while depressing the accelerator pedal, the vehicle failed to respond. The contact stated that seconds later, the vehicle responded, and the vehicle hesitated and moved forward independently. The contact stated that during the failure, there was a vibration coming from the rear passenger’s side wheel, and the vehicle lost motive power while driving. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the diagnostic result was unknown. …”

“Vehicle suddenly loses power while driving. Engine does not turn on, vehicle will run on battery until battery is dead, then putting the vehicle in park once stopped. Vehicle will not accelerate normally since the engine does not turn on. Only goes 10-20 mph. Lights on the dash come on, prompting to keep car on to charge the battery. No code is found when the vehicle is scanned. Dealerships can't seem to diagnose the issue. This is a safety concern when driving on busy roads or state highways at higher speeds.”

“At times vehicle hesitates or doesn't responses when accelerator is pushed. Has occurred several times when moving into traffic from a yield lane or stop. Fortunately it hasn't lead to an accident but was very scary. Researching this problem on-line, this has been reported by many Sorento owners. This is an intermittent problem and when vehicle is taken to the dealer they report they can not duplicate problem so nothing is done. By the shear numbers of owners reporting the same issue, something needs to be corrected.”

“While driving on September 15, 2025, the vehicle displayed a loud beeping and the warning message “Check Hybrid System. Stop Safely.” The vehicle restarted about an hour later, but the combustion engine ran very rough. The Kia dealer inspected it but reported no stored error codes. On September 23, 2025, the vehicle suddenly lost power while driving. It appeared to operate only on electric at low speed, then died completely in the roadway. The vehicle would not power down until the start/stop button was held. It required a tow back to the dealer. …”
