2023 Kia Sportage Hybrid

I am filing a safety complaint regarding my 2023 Kia Sportage Hybrid. The vehicle developed a “Check Hybrid System” warning and was diagnosed by a Kia dealership as having a failure involving the high-voltage hybrid system, specifically the MCU (Motor Control Unit). The dealership informed me that the vehicle may be unsafe to drive due to the possibility of fire risk associated with the high-voltage system. I was told technicians had to use specialized protective equipment while diagnosing the issue and that the diagnosis process took nearly a week. The repair estimate was approximately $5,000, in addition to approximately $750 charged for diagnostics alone. The vehicle is reportedly out of warranty due to mileage, even though this appears to involve a major hybrid system component and a potential safety defect. This concerns me because: - the vehicle is a relatively new 2023 model, - the failure involves the high-voltage hybrid system, - Kia advised the vehicle may catch fire, - and independent mechanics generally cannot service or repair these proprietary hybrid components. I believe this may represent a broader safety issue or defect involving the hybrid system or MCU components in Kia hybrid vehicles. I am requesting that this matter be investigated for possible safety defects, recall eligibility, or manufacturer responsibility.

When driving on the highway, warning lights activated on the dash with the message "Check Hybrid System. Stop Safely." Seconds later, the vehicle lost all propulsion power. The hybrid battery indicated it had a half charge and the combustion engine was running. Depressing the accelerator caused the engine to increase RPMs but little to no power was output to the wheels. I turned the car off and all electrical systems were disconnected and the car would not start. I pressed the "12V Battery Reset" button and electrical systems were restored and I was able to start the car. The failure then repeatedly occurred. This issue has presented multiple times now, all while driving on the highway.

I would welcome making my vehicle available for inspection on this issue. Year/Make/Model: 2023 Kia Sportage EX HEV AWD 4-Door SUV Color: Black Powertrain: Hybrid Electric Vehicle (HEV) Number of occupants: 2 (driver and passenger) Injuries: None, but fatalities could have occurred. Vehicle turned off completely – no power, no hazard lights, and although driver miraculously made it to the shoulder, most of it was blocked by a snowbank and sat in a dead car with no hazard lights. Passenger (recovering from leg surgery in full leg brace) was forced to exit onto a snow bank and enter a tow truck cab, risking re-injury. Crash: No — vehicle was somehow brought to shoulder and aid protected by two state trooper vehicles until a tow arrived. Our car suddenly emitted a loud alarm at highway speed on I-84 -the instrument panel displayed an "stop vehicle immediately" warning. There was no prior warning, unusual noise, or dashboard indication of any problem. The car shut completely down while still on the highway. Car was towed to the nearest KIA dealer - Columbia Ford/Kia [XXX] ). After diagnosis, the authorized Kia dealer documented the following on Repair Order Invoice W7403: • Concern: "TOW IN. DIED WHILE DRIVING. SEPARATED" • Diagnostic fault code: BMS P1BB20 • Failed/replaced parts: ◦ DECOUPLER-BASFILTR, Part No. SPO 25290 2MHD0 ◦ BOLT-CRANKSHAFT, Part No. KIA 23127 2MHA0 ◦ BATTERY MODULE ASSY, Part No. SPO 37507 L5000 • Parts total: $835.54 • Vehicle in dealer possession: March 5, 2026 – March 20, 2026 (15 days) complete loss of motive power at highway speed. Based on my subsequent research, this failure mode appears consistent with a documented similar issue in the United Kingdom and European markets - which did result in a recall. -hybrid belt/tensioner system. Kia issued revised parts and ECU updates in those markets. No equivalent safety recall or consumer notification has been issued in the US.

The AC compressor failed on my 2023 Kia Sportage Hybrid after 2 1/2 years of service and 59,800, mostly highway, miles. This affected the vehicle's drivetrain and it ground to a halt many times with a message "Check Hybrid System" displayed on the dashboard. The problem occured randomly and initially every few minutes when the vehicle was stopped at traffic lights, creating a real danger of being rear-ended by other cars.

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.

While driving, the vehicle repeatedly displays “Check Hybrid System – Stop Safely”, followed by loss of acceleration and shutdown of the 12V system, rendering the vehicle unable to drive. These incidents occurred on both freeways and local roads. To avoid a collision, I was forced to activate hazard lights, pull over, shut the vehicle off, and attempt recovery using the 12V reset procedure or an external jump starter. The issue has persisted despite multiple dealer inspections and repairs and presents a serious safety risk.

Ev battery system threw up back back to earnings and codes of overcharge and then all lights on dash came on started beeping and then dash went red saying check hybrid system , hybrid system failure stop vehicle. Engine wouldn’t kick back on. I had literally just left my local Kia for a routine checkup and there report is nothing is wrong. Even tho I’ve called them now a few times about it shaking and idling super hard and going limp very often. Towed back to Kia and they have now had it for 4 days and still no results.

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.

The contact owns a 2023 Kia Sportage Hybrid. The contact stated that while driving, the vehicle unexpectedly stopped. The contact noticed that the coolant level was low, and additional coolant was added. The vehicle was taken to the local dealer, where it was diagnosed with a loss of fluid. The vehicle was repaired, but the failure recurred. While driving on the highway, the vehicle stalled. The vehicle was coasted to the side of the road. The message “Hybrid System Failure” was displayed. The vehicle was restarted after several minutes. While driving, the vehicle stalled, and the contact was able to pull over safely. The vehicle was taken to the local dealer, who was unable to retrieve any fault codes. The vehicle was not diagnosed or repaired. While driving in the center lane, the vehicle stalled. The driver turned on the hazard lights while coasting to the side of the roadway. The vehicle was taken to the same dealer, but the dealer was unable to duplicate the failure. The manufacturer was contacted and opened a case. The failure mileage was approximately 1,500.
