2023 Kia Sportage Hybrid acceleration problems

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!

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.

3 times in the last two days, and dozens of times over the last six months, while driving or while idling, the "check hybrid system" warning has flashed. When it happens the car does into limp mode, where it will go no faster than 13mph. this has happened in the left lane of a highway where there is no where to pull over except the lane, since there is no time to get over before the vehicle shuts down. the car essentially will shut down in the middle of driving, no matter where it is. Especially with my kids in the car it is terrifying hazard. I have brought the car to the Kia service and since its not easily reproducible they have not been able to help and have offered no solutions.

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.

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.

September 2025 (58,000 mi): Vehicle will not start without manually resetting 12v battery module integrated in hybrid battery system. Pattern suggests hybrid control system defects, not resolved by previous repair. Car has now been with dealer for 4+ days figuring out this issue.

After driving for roughly 7 hours upon activating my cruise control, after using the entire drive with no issues, it went up to 110 mph as soon as I hit the button and would not allow me to adjust the speed down. It would turn off upon pressing pause, cruise control, or brakes but would rise to 110 mph everytime. I searched for recalls for this and could find none. But I did find posts of other people with the same issue. The only thing I could find was an emissions campaign that seems like it may be related. This appears to me to be much more of a safety issue especially if the driver is not paying attention. Or for example let's say you're driving behind someone and turn cruise control on you could very easily rearend someone at a high rate of speed. I will be trying to get my car into the dealership to try and resolve the issue, but my main point for filing a report is to see if this rises to the level of a safety recall versus a tsb or emissions campaign. My vehicle is available for inspection if needed. No warning lights came on or anything of the sort. I do have a video of this but does not appear I can upload it. Any assistance is greatly appreciated thank you and have a great day

While driving on the highway at 80 mph, the accelerator suddenly stopped working and was completely unresponsive. The dashboard displayed the message "Check Hybrid system. Stop safely" and a warning ding sounded. The gas engine was still operating and showing RPMs on the dashboard, but all acceleration and/or engagement with the engine was lost. I was able to coast and safely pull over to the side of the road. After pulling over, I turned off the engine and pushed the 12v battery reset button. The car restarted, and I was able to continue driving. The issue repeated about 20 miles later and again on a different drive four days later. Each time, there is no early warning or noticeable issue with the vehicle before the sudden warning and loss of power.

I was driving with cruise control on. I had to slow down for traffic. Upon resuming speed, I reactivated cruise control at which time it jumped to 110 mph. This happen several times. I turned cruise off and back on 110. I canceled and tried to reset, 110. I kept resuming 110 mph and the function was not usable. I have a video but was unable to upload because it was to large

I was going 40 mph and tried to set the cruise control to my current speed. The cruise control set at 110 mph instead. I tapped the brake to stop the cruise control and it stopped. I tried to set the cruise control again multiple times and the same thing happened. I parked, turned the car off then on again and the cruise control worked like normal.
