2022 Kia Sorento

Vehicle flashes Auto Start Stop icon on the dashboard, which is not commonplace. When this occurs, the vehicle can not accelerate when the accelerator is actuated. The vehicle can not accelerate past 40mph and the RPM is sporadic. This happens randomly and can not be diagnosed by the dealership. Multiple dealerships have tried and none can duplicate this issue. This is a severe safety concern and seems to be common all over multiple forums.

The contact owns a 2022 Kia Sorento. The contact stated that while driving at an undisclosed speed, the Auto Hold feature activated, and the check engine warning light and several other unknown warning lights illuminated. The vehicle was taken to an independent mechanic, and DTCs U0164, U0123, U01B0, and U1131 were retrieved. The independent mechanic stated that the battery needed to be replaced. The independent mechanic also informed the contact of an unknown recall; however, the VIN was not under recall. The vehicle was repaired; however, the warning lights illuminated, and the failure persisted. Additionally, the parking brake warning light was illuminated. In addition, the air conditioning system was leaking refrigerant and intermittently was blowing out hot air. The A/C started blowing colder air minutes later. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 69,900.

2022 Kia Sorento failed to increase speed when accelerator was depressed , engine RPMs increased, but no subsequent speed increase. The Amber ISG light was flashing, with no other warning lights. The car was driven to a safe pull out, placed in park, turned off and restarted, no flashing light. The car accelerated satisfactorily afterwards. This has happened several times in the last two years. Both fuel pumps were replaced as well as the battery and computer systems were reset and the problem still intermittently persists. This is a significant safety issue if the car cannot properly accelerate when required to merge into traffic and properly maintain designated speed. Was told that Kia engineering said this maybe a heat related issue, the car is operated mainly the the southwestern US, Phoenix, Az metropolitan area.

I am submitting a formal safety complaint regarding my 2022 Kia Sorento, which is experiencing a dangerous and recurring loss of engine power during acceleration. This issue presents a significant safety hazard, particularly during situations requiring immediate acceleration such as highway merging, crossing intersections, and passing traffic.

The vehicle has less than 75k miles, and I am the second owner. I was driving, and the vehicle lost power. Creating a traumatic experience that could have been fatal. After Kia had inspected the vehicle, I was informed that I needed a new engine and it would cost 8k or more, and my extended warranty would not cover it. Kia has current recalls for similar issues.

Kia refuses to perform a U.S. safety recall due to my being active duty U.S. military stationed overseas. The affected vehicle is U.S.-spec and registered to a U.S. address. The recall (SC250) involves sudden loss of drive power and is a major safety defect. Kia has refused to authorize parts or repair overseas, putting me and my family at risk.

2022 Kia Sorento X-line SX Premier model (89435 miles) 2.5 l Turbo GDI is going into limp mode when trying to accelerate. The (A) Auto Stop indicator illuminates. Pulled car over, placed in park, turned off, restarted after waiting about a minute, no warning lights, car drives and acceleration is normal. About one year ago, car experienced the same problem, took to dealer for diagnostic troubleshooting, the battery was suspected and replaced, issue persisted, the codes indicated either low pressure or high pressure fuel pumps, the low pressure pump was replaced, after further drive testing by the dealer issue was still present, the high pressure pump was replaced and the issue was resolved. Fuel pumps were replaced under warranty. Kia dealer said that Kia engineering believes the issue is possibly heat related, I live in Phoenix, Az. Summertime temperatures exceed 100 degrees in summer some days exceeding 110 to120 degrees. A month ago September 2025, the car experienced limp mode again this time with check engine light, problem was identified with faulty low pressure fuel pumps gasket which was replaced. The limp mode has been experienced again 5 times in last month, twice today. Ambient Temperature in 80s. This is a significant problem that could lead to a possible accident if the car fails to accelerate properly. My wife is afraid to drive the car until the failure mechanism is identified and is properly repaired.

The design of the grill on this vehicle is poorly constructed and leads to safety issues. I purchased the vehicle in October 2024 and early January 2025, my husband was driving on the highway when the vehicle stopped. No lights, no warnings, just stopped providing power-while driving at a high speed on the highway. He was able to make it to the side of the road and get home that evening only to find out the radiator was punctured and needing replacement. Just 4 months later the exact same thing happened. The grill has no protection for an essential part of the vehicle. Minor road debris can completely shut down the vehicle, without warning, leading me to believe it is not intended to be on the road with its current design. The dealership has replaced the radiator both times and I’ve reached out to Kia directly. This is not an uncommon issue for this model. Many accounts of this exact same problem on social media and other public forums. Kia is aware this design flaw puts their customers at risk and are doing nothing to prevent it.
