2023 Kia Sportage Hybrid: check engine light

Filed Aug 21, 2026 · Acceleration, Electrical · CA

2023 Kia Sportage Hybrid. Drop in power/acceleration! Upsetting, stressful & unsafe. Purchased brand new, Nov 2023. When this occurred approx. 35695 miles. I left work, got on the freeway, (only maybe 1-2 miles away) and was trying to accelerate to merge with traffic flow and could only go approx. 52-54 MPH. I tried to "floor" the pedal, but with no further acceleration. No check engine light turned on, only display message noting depleted battery/drained warning. Since power was limited, and unsure of safety of driving further or if the car would literally stop, I pulled to the shoulder of the freeway. It is a miracle that I was in the slow lane already! Unsettling! It was towed to a Kia Dealership. They had it for 2 days. The technician said there were two error codes (P017100 - System Too Lean, and P019100 Fuel Rail Pressure Sensor Circuit Range/Performance). They were unsure how/why this incident occurred. They said some kind of glitch in the system. I asked if they have had other cars with this similar issue brought in, and the technician said he did not know of any. The issue was not replicated upon initial diagnostics. Technician cleared codes, reset the engine adaptive values and road tested, and deemed the vehicle "safe to drive". But said if it occurs again, try turning off the engine, wait a bit and try driving! WHAT?! Also if it occurs again to bring it back and a technical ticket should be opened to investigate further. I have read online forums of this SAME issue, and it is a KNOWN ISSUE "especially early-production 2023-2024 models, and hard for dealers to reproduce issue after a reset". It is also noted that "many cases resolve with the free BMS software update or related module/control unit work under warranty. Some report reoccurrence even after updates". I found this information AFTER the fact, otherwise I would have pushed for the software update or related work to be done. I plan to seek that out next!

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.

The vehicle frequently fails to engage gas engine when depressing gas pedal to any degree. A full push of the gas pedal does not result in gas engine engagement. This has happened over 15 ties since the recall computer update last summer (2025). This creates extreme danger because the operator expects the full power of the engine to engage when pulling out of intersections or crossing oncoming traffic, but the engine does not engage causing a slow, creeping acceleration from the electric motor only. I took it into the Kia dealer and they found nothing wrong. No warning lights occur when the malfunction happens. And no check engine lights occur either. The only correction is to fully turn the vehicle off and back on. Doing that resets everything back to normal. This malfunction usually occurs within the first 25-30 minutes of vehicle operation.

The hybrid powertrain system failed. Specifically, the vehicle remains stuck in EV mode and does not switch to the gasoline engine under acceleration, leading to complete loss of power while driving. Yes, the vehicle is available for inspection upon request. This malfunction caused the vehicle to lose all forward power in traffic. I had to pull over into emergency lanes and restart the vehicle multiple times. This is extremely dangerous and could lead to a crash, especially on highways or during merging. It puts both myself and others on the road at risk. The Kia authorized service center was able to reset the adaptive system, and the hybrid warning light turned off temporarily. However, the issue reappeared the same day. The dealer claims they cannot reproduce it and refuses further diagnosis without replication. The vehicle was only inspected by a Kia-authorized dealership. Kia Consumer Affairs has not yet conducted a manufacturer-level inspection or assigned a field technician. Yes. A “Check Hybrid System. Stop Safely” warning message appears before the failure occurs. Then check engine light was on. It first appeared immediately after a routine service (oil change, tire rotation, multi-point inspection) on 26th June 2025, just 2 days after my regular service. The warning disappears after restarting but returns intermittently, typically after the EV battery is fully drained and the car fails to switch to gas mode.

On June 9, 2023, the owner purchased a brand-new 2023 Kia Sportage Hybrid from Quirk Kia Braintree. Over the next six months, the owner regularly drove the car between work and home, accumulating approximately 4,500 miles. However, in early January 1st 2024, the owner noticed that the check engine light had illuminated, although there were no other noticeable issues with the vehicle at that time. In response to the warning light, the owner ceased using the car and promptly scheduled an appointment with Quirk Kia for a diagnosis. When the owner attempted to drive the car to the dealership, it exhibited severe shaking when the engine was running, rendering it undrivable. Subsequently, the owner had the car towed to Quirk Kia, where it has remained since January 5, 2024. Upon examination, multiple error codes were detected, yet as of January 17, 2024, the dealership has been unable to determine the root cause of the engine's shaking. They have raised the possibility of poor-quality gasoline as a potential culprit, and they claim to have conducted tests on the fuel. Based on the email and phone communications between the owner and the dealership, the owner believe that the gasoline used was of good quality (the owner consistently refueled at Costco). Additionally, three pictures of the fuel test were shared (attached), indicating that the ethanol content in the gasoline was below 10%, which aligns with the car's manual specifications. Their proposed solution is to replace the gas tank, with the cost to be borne by the owner. The owner find this resolution to be entirely unacceptable.

While driving 30-40 mph most of the Advanced Driver Assistance System warning lights came. The check engine light, service light, etc also came on. There was a notice that kept flashing do not drive vehicle. This has happened on three occasions. There were zero issues prior to this. On one occasion I was driving on a two lane mountain highway and had to continue driving the vehicle because there wasn't an emergency lane nor pull off. Having all the warning lamps flashing was extremely nerve racking and frightening. The vehicle has been at the dealership for two weeks. I'm told that a national ticket has been opened and there are no updates available as of this writing(09/01/22).
