In the evening, while driving home after dinner with my daughter in the vehicle, I was traveling in the area of [XXX] and [XXX] when the vehicle displayed a “STOP SAFELY IMMEDIATELY” warning. The vehicle unexpectedly slowed down/appeared to brake on its own while I was driving.

Intermittently, when coming from a stop (stop sign, red light, etc) or recent start of the vehicle, the Sorento will not accelerate past approximately 30 miles per hour and the auto-stop light will flash orange in the panel. Once the vehicle is stopped, turned off, and restarted, it goes back to operating as it should and accelerates like normal. This has happened when driving on small, low speed limit roads and on large, high speed limit roads. My safety and the safety of…

I have taken my vehicle to the dealership multiple times to address ongoing and serious safety concerns. Despite having active warranties on the transmission and powertrain, I have continually been told that there is nothing they can do, and my concerns have not been properly addressed. The vehicle is…

On 3/26/2026, I was driving at 45mph when the vehicle started slowing down and the auto stop light on the dash was blinking yellow. Every time it blinked, the car slowed even more. I tried to speed up, but it slowed down more. This could have caused an accident. I pulled off on the side of the road and shut the car off. I waited a few minutes and started the car. It ran alright and the light did not blink. It has been alright so far. If it occurs again, I will call the…

Component: Electrical System / Forward Collision-Avoidance Assist / Speedometer Incident Summary: I am reporting a catastrophic and uncorrected safety defect in my 2021 Kia Sorento (VIN: [XXX] ). Pre-Accident Attempts: Before April 2024, I repeatedly sought diagnosis for instrument cluster 'glitches.' The Kia dealer misdiagnosed this as a battery failure, charging me out-of-pocket for a replacement that did not resolve the issue. Collision (April 22, 2024): While driving,…

My vehicle completely shut off while I was driving with my children in the car. The dealership replaced the battery but never identified the root cause. Since then my car has been experiencing RPM surging while in Park — the engine revs up and down repeatedly on its own. The vehicle also feels sluggish and does not want to accelerate properly while driving. Additionally since taking ownership of the vehicle my window has squealed every time it rains and I roll down the…

The issue appears to involve the electric oil pump and related components. My 2021 Kia Sorento had a recall for the electric oil pump that was marked “completed” in January 2023; however, the dealership only performed a software update and did not replace any mechanical components because no fault code was present at that time. Beginning around October 2025, the vehicle started experiencing drivability issues including hesitation and bogging down when accelerating from a…
