Kia Sportage Hybrid check engine light comes on

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.

While navigating the highly dangerous downhill descent of the Tejon Pass, LEBEC, CA , the vehicle experienced a complete throttle disengagement. The accelerator pedal became entirely unresponsive, leaving the vehicle without power on a steep, high-speed highway descent. I was traveling with my young daughter inside the vehicle. Due to the sudden loss of propulsion, I was forced to make an emergency maneuver and pull over onto the shoulder on the left side, right next to the high-speed passing lane. This situation put our lives in immediate danger of a catastrophic high-speed rear-end collision. A highway patrol that drove by within 5 mins was able to assist by blocking the downhill highway cars so I can drive down on Neutral Gear until a safe spot ( which it was a very stressful life endangering maneuver). Only Warning light I got was the Yellow engine light but no text indication of failure. Car was tolled to the dealership today for scanning. This is the first time that an event like this occured. Car has around 35 K miles and under warranty. All services have been performed ( last was 2 months ago)

I own a new 2026 KIA Sportage Hybrid VIN: [XXX] Odometer reading 1,200 miles On XXX while accelerating at freeway speeds the vehicle suddenly lost power and went into “reduced power mode” which slows the vehicle to a near stop. A Check engine light came on and two messages appeared. One message read:” Follow-up check required 1” and the other read: ”There may be a problem with the engine management system. If the warning light remains on please contact your nearest service center or designated maintenance center as soon as possible.” I immediately took the vehicle to a KIA dealership and they said they replaced an oil pressure sensor that they believed caused the problem. Odometer reading 2,450 miles On XXX while accelerating at freeway speeds the vehicle suddenly lost power and went into “reduced power mode” The same warning messages that appeared during the first power loss incident appeared again. After turning the vehicle off and on a few times the messages disappeared and I was able to drive it again. The vehicle is currently in a second KIA dealership for diagnosis and repairs. Both of these incidents occurred when I was passing tractor trailers on the freeway and had just pulled in front of them after passing.

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 system completely failed and ev battery completely discharged. That issue is a major safety concern and I no longer feel confident driving myself and my child in that vehicle. I was on a hilly 55mph County Road, with few turn offs, when the hybrid system failed, resulting in a loss of acceleration, power steering, power brakes and heat. Check engine light, Oil Light and battery light illuminated while entire dash display started flashing red with critical fault message. The vehicle then went into limp mode. Dash showed that hybrid battery was completely discharged and warning message displayed saying vehicle would shut off in 5 minutes. Able to restart after a few minutes, but warning light said vehicle had to be left in park and vehicle started shuddering hard. It was a frightening few minutes trying to get to a safe place to turn off and park with the dashboard flashing red. The vehicle had to be towed to the dealership. The vehicle would not go into neutral and the tow company had to drag the vehicle with wheels locked onto the flatbed. The Kia dealership service department states both the wiring harness and wiring fuse box need to be replaced as a result of the hybrid system failure. I have reached out to Kia Customer Care and currently have a case opened with Kia that has been escalated. Prior to the hybrid system failure, after vehicle was at dealership for routine maintenance, a code P052400 appeared and vehicle had to return to service dept to address code. That code was NOT present when vehicle went in for its routine oil change and tire rotation. I still do not have my vehicle back. It has been at the dealership in service since December 1, 2025. According to the service department, the parts needed are on backorder with no ETA.

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.

The infotainment screen goes out randomly while driving and can stay off for the entirety of the trip. That includes the speedometer, check engine light, fuel gauge, etc.

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.
