2023 Kia Sportage Hybrid electrical system problems

“Driving on hwy, hybrid battery light comes on. Car basically dies you have to pull over, shut car off, hit battery reset and start . Very dangerous It's been happening off and on for a while. Started about 28000 miles , now have 42000. Dealership is 1 1/2 hrs away, very heavy traffic. Plus our only car and have to work various hrs. No rental car avail. Can happen 6-7 times one day then a month goes by nothing.”

“I was driving on the highway going about 70mph and the car completely shut off. When off I couldn’t accelerate or brake. I put my hazards on and pulled over. The car continued to turn off and on. It couldn’t stay on. Still don’t know what’s wrong with it but a HUGE safety concern.”

“Was driving my child to school when the Hybrid System alert came on, I only had a few seconds to try and pull over before the car completely shut down, we lost all motive power. I was on a downward incline right in front of an uncontrolled intersection with very little shoulder as I live in a rural mountain town. Since the parking brake is part of the integrated system I did not feel I had full control of the car while pulled to the side and even moved a bit while trying to wait to restart the system via the 12volt re-set button. This was a very serious safety issue, the difference of less than a minute could have led to my child and I being helpless in the middle of a highway intersection. This is a reoccurrence of a previously documented problem from April of 2026. We took it to an authorized dealership for repair who stated it was due to two battery cells reading higher (diagnotic codes P1B200 and P0A1B), they performed a BMS cell balance and reset the values. Despite the repair the same situation occurred again in a significantly more dangerous situation. I was able to drive the car home with no reoccurrence but due to the unpredictable nature and severity…”

“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…”

“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.”
