2023 KIA SPORTAGE HYBRID Complaints

I was driving my 2023 Kia Sportage Hybrid when the vehicle displayed a "Check Hybrid System"/ "Stop Safely" warning and suddenly lost motive power/acceleration. I was unable to accelerate normally. I had luckily pulled of the road that I was going 55 mph into a parking lot prior to the lass of power or I would have stopped right on the roadway with cars going the same speed directly behind me. This created a serious safety concern because if this had occurred while traveling at highway speed or in heavy traffic, the sudden loss of power could have resulted in a collision. There had been no indication to me that the vehicle was about to lose motive power before the hybrid-system warning appeared. The vehicle is currently at an authorized Kia dealership for inspection and diagnosis. The cause has not yet been provided to me. The vehicle is available for inspection. I am reporting this because a sudden loss of motive power associated with a broad-system warning presents a significant safety risk. I have also learned that other Kia Sportgage Hybrid owners have reported similar hybrid-system warning and loss-of-ower incidents.

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!

Electronic parking brake switch has failed. Yes the switch is available for inspection. Electronic parking brake can no longer be manually activated. Failure of the electronic parking brake switch has been confirmed by a dealer (Citrus Kia, Ontario, CA). Electronic parking brake switch has not yet been inspected by the manufacturer, police, insurance representatives or others. No warnings have been given regarding function of the electronic parking brake switch.

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 contact owns a 2023 Kia Sportage. The contact stated that while driving at an undisclosed speed, there was smoke coming from the engine compartment and the vehicle stalled. The check engine and battery warning lights were illuminated. The vehicle was towed to a dealer to be diagnosed; however, the diagnostic result was unknown. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 104,000.

The contact owns a 2023 Kia Sportage. The contact stated that while driving 75 MPH, the engine seized. The hybrid engine message was displayed. The vehicle was driven to the shoulder of the road and parked. The contact stated that while attempting to restart the vehicle, the vehicle started. The contact reset the instrument cluster. The contact stated that the failure had occurred while driving on a busy four-lane highway. The failure was a persistent failure. The dealer was made aware of the failure. The vehicle was taken to the dealer. The contact stated that no diagnostic information was provided. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the vehicle had experienced an EVAP leak in April 2026. The vehicle was at the dealer for two months and was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 45,445.

On XXX and XXX, while driving on the highway, the vehicle suffered a sudden, complete loss of motive power. Flashing warning lights appeared on the instrument cluster, accompanied by a safety warning message instructing the driver to pull over and "Check Hybrid System" immediately. This sudden, uncommanded drop in propulsion on active, high-speed roadways created an immediate safety hazard, forcing emergency maneuvering to coast the vehicle safely to the shoulder. The vehicle was delivered to an authorized franchise dealer (Arapahoe Kia in [XXX]) on XXX, where it has now remained grounded for 31 consecutive days. The service department has verbally communicated extreme diagnostic confusion, stating they lack an on-site hybrid specialist to properly diagnose the high-voltage powertrain/HPV/hybrid battery system. The vehicle has historically received software updates under Campaign SC335A, and the symptoms reported here closely align with the loss of motive power issues addressed in Voluntary Emissions Service Campaign SC338. To date, neither the dealership nor the manufacturer (under Case #XXX) has provided a formal written diagnosis, a repair schedule, or an active resolution.

The car's transmission became unresponsive and caused the car to lose the ability to accelerate. This happened twice on the highway before I could get it to the dealer. In order to recover, I had to pull over on the shoulder and turn the car off, wait, and turn it back on. The dealer, through the Kia warranty service, would only 'recalibrate' the transmission and refused to service it. After the recalibration, the dealership wanted to give me back the car. I insisted that they took it for an extended test drive in which it stalled for them as well. Kia warranty then authorized the replacement, and I am awaiting its completion.

Over the past 11 weeks, my 2023 Kia Sportage has experienced sudden, complete loss of acceleration on at least three separate occasions while driving at highway speeds. Each incident is accompanied by the battery gauge dropping to zero. I was forced to stop on the highway to restart my vehicle in order to drive it again. No error codes are stored because the fault clears on restart. I have taken the vehicle for inspection to a mechanic and Kia Dealership Marin, neither were able to diagnose or repair the issue.

REAR PASSENGER SEAT BELTS ON BOTH DRIVERS AND PASSENGER SIDE: The seat belt would not fully pull out/extend, and allow the passenger OR the child safety seat to be properly secured. It would lock up, and once the belt was pulled out, it would lock up on the retraction and not allow any extension. I took to the KIA dealership - which took a total of 3 visits- DEMONSTRATED and recreated the issue- which confirmed there was a problem. This did not happen on each use, but once I realized the child safety seat could not be installed properly (fully extended seat belt, retraction/ratcheting of belt to secure seat) I returned, and asked the service manager also observe along with at least one of the service techs. They were skeptical and not even fully aware of how a child seat should be installed, and the full extension of the seat belt, and the SOUND of the ratcheting/locking of the belt once fully extended. A repair/replacement was eventually done- parts had to be ordered and I could not find this “defect” on any KIA or other websites. It took a number of days for the replacement/repair. There were no warning lights that there were any problems with the safety belts. I (retired) police officer with NHTSA safety seat instructor certification (not current) and have knowledge of this, and it wasn’t until I explained and demonstrated the system to these dealership employees the proper function did they “believe” me. I just read of the a KIA recall on their Telluride models, and it sounds like a similar problem. Until it was fixed, I had a couple of occasions where the passenger was unable to secure their belt, which was before I realized that there was a manufactured problem with this system.
