2023 Kia Sportage Hybrid Fuel system Problems

My 2023 Kia Sportage EX Hybrid has experienced repeated engine-related failures since October 2022, requiring multiple dealer repairs. The safety issue escalated in 2026 when the vehicle experienced sudden loss of acceleration while driving on highways. In April/May 2026, the vehicle lost acceleration twice within approximately 10–15 minutes. Warning messages appeared, including Check Engine Light and "Check Hybrid System – Stop Safely." The accelerator became unresponsive, requiring the vehicle to be moved to the shoulder. The dealer diagnosed P0030 and P1120 and replaced the Bank 1 Sensor 1 oxygen sensor and valve cover assembly with manufacturer technical support involved. Several months later, another highway loss-of-acceleration event occurred. The vehicle would not respond to the accelerator, RPM remained around 1,000, and it had to be safely moved off the road. The dealer diagnosed P2138 and replaced the accelerator pedal assembly. The repeated unexpected loss of acceleration creates a serious safety risk. The root cause remains unknown despite multiple repairs.

When driving on the highway, warning lights activated on the dash with the message "Check Hybrid System. Stop Safely." Seconds later, the vehicle lost all propulsion power. The hybrid battery indicated it had a half charge and the combustion engine was running. Depressing the accelerator caused the engine to increase RPMs but little to no power was output to the wheels. I turned the car off and all electrical systems were disconnected and the car would not start. I pressed the "12V Battery Reset" button and electrical systems were restored and I was able to start the car. The failure then repeatedly occurred. This issue has presented multiple times now, all while driving on the highway.

While driving, the vehicle repeatedly displays “Check Hybrid System – Stop Safely”, followed by loss of acceleration and shutdown of the 12V system, rendering the vehicle unable to drive. These incidents occurred on both freeways and local roads. To avoid a collision, I was forced to activate hazard lights, pull over, shut the vehicle off, and attempt recovery using the 12V reset procedure or an external jump starter. The issue has persisted despite multiple dealer inspections and repairs and presents a serious safety risk.

Vehicle flashed with a "check hybrid system. Stop safely" warning and then forced me to slow until my vehicle stopped - I could no longer press the gas pedal. I was on a highway and luckily was able to pull over safely before the vehicle came to a complete stop, but that was not guaranteed. I ended up being towed to a Kia Dealership where they informed me this was an issue under recall, but that recall is not listed on your system nor was I ever informed of the recall by the manufacturer.

My 2023 Kia Sportage Hybrid, with only 22,000 miles, has been experiencing a recurring "Check Hybrid System Stop Safely" error, causing sudden and complete loss of acceleration while driving. This issue first occurred in November 2024, while I was driving at highway speeds (60 mph), and has recurred multiple times since. The sudden loss of power puts my safety and others’ at serious risk by leaving the vehicle stranded in traffic, increasing the chance of accidents. On December 30, 2024, I brought the car to Kia of West Nyack for diagnosis and repair, providing video evidence of the error. However, the dealership claims they cannot replicate the issue and has not completed any repairs. While the dealership has stated since last week that a Techline case was opened, Kia Corporate confirmed no such case exists, highlighting a lack of accountability and coordination. For over two weeks, no progress has been made, and the issue has not been escalated to a specialist. Despite being under warranty, I have not been offered a loaner vehicle, significantly impacting my daily life, work, and family responsibilities. This issue is further complicated by Kia’s inability to log intermittent errors, as the "Check Hybrid System Stop Safely" message disappears when the car is restarted. This design flaw has allowed the dealership to dismiss the error as unreproducible, despite video evidence provided. This situation has left me questioning whether my car is safe to drive and when it will be repaired. This defect is not isolated to my vehicle. Many other Kia and Hyundai hybrid owners have reported the same error, highlighting a widespread safety issue. Despite its warranty obligations, Kia has failed to act promptly to address this defect. Immediate action is needed to ensure the safety of this vehicle and others affected by this recurring problem.

This is a heads up, not an incident report. On this vehicle there is a push button starter on the center console. Page 6-11 of the owner’s manual has a warning that reads, “Never press the ENGINE START/STOP button while the vehicle is in motion. This would result in loss of directional control and braking function, which could cause an accident.” I feel this is a hazard with an easy fix: disable the start button if the vehicle is in motion. A toddler could reach over and press the button for fun. A person could drop an object on it accidentally. I’m sure there are other scenarios where that button gets pushed inadvertently. Thank you.
