Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

My car will randomly go into limp mode and I am unable to accelerate. The auto stop/start light will flash orange on the dashboard. I need to pull over and restart car and it seems to reset. I see there is a recall for a 2021 KIA Sorrento but I don't think it affected my vehicle even though the issue is exactly the same. Recall #22V6000. It happened once a few months ago then didn't reoccur until about two weeks ago and it has happened three times since. It is scary because I am afraid to cross traffic in fear that the car won't move fast enough

NHTSA ID 11751187 · filed Jul 17, 2026

I am filing this complaint regarding my 2021 Kia Sorento, which has suffered a serious transmission failure. The vehicle is displaying diagnostic code P0741, indicating a torque converter clutch malfunction. The transmission slips, shifts harshly, hesitates during acceleration, loses power unexpectedly, and has become unsafe to drive. The vehicle is available for inspection upon request.This defect has put my safety and the safety of others at risk. On several occasions the vehicle failed to respond properly when accelerating, including while entering highways and driving in traffic. The hesitation and sudden loss of power created fear and anxiety because I could not trust the vehicle to move when needed to avoid a dangerous situation. The problem has been reproduced and confirmed by a repair facility, and the symptoms are consistent with a transmission torque converter clutch failure. I also contacted Kia and provided the vehicle information. Kia informed me that they would not repair the vehicle because it has exceeded 100,000 miles and that the recall or warranty extension had expired. However, my vehicle is experiencing the same transmission-related symptoms reported by many other Kia owners.I never received any recall notification because I purchased the vehicle from a dealership as the second owner. Had I been properly notified, I would have taken the vehicle in for inspection much earlier. It is extremely frustrating and financially devastating to be denied assistance solely because of mileage when the failure appears to be related to a known transmission defect.Before the failure, the check engine light illuminated and code P0741 appeared. Prior to that warning, the vehicle had already shown delayed shifting, slipping, hesitation, rough gear changes, and loss of power, which became progressively worse.This situation has caused significant emotional stress, anxiety, and financial hardship. I am requesting a full investigation and a fair resolution from kia.

NHTSA ID 11756015 · filed Aug 10, 2026

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 those driving around me is put at risk when vehicles around me are expecting me to drive a certain speed but I can't and am looking for a safe place to pull over to stop and restart the vehicle. To date, the vehicle acceleration has not suddenly dropped from a high speed to a low speed thankfully, but when the issue presents itself, it will not allow the vehicle to accelerate above the 30mph range. The vehicle is available for inspection upon request. It is currently at a dealership that is working to reproduce and confirm the problem. There are Reddit threads that discuss other Sorento owners experiencing this same issue. To my knowledge, there were not any warning lamps, messages, or other symptoms of the problem prior to this issue presenting itself. It has been happening on and off for the last 1-2 years. My vehicle has not been inspected by the manufacturer, police, insurance representatives, or others but I am happy to have any of them do so. A simple battery replacement has not resolved the issue - it was happening before I had my battery replaced and it has happened since having my battery replaced.

My windshield randomly cracked from driver side top edge and down in a diagonal direction. There is no visible impact from an object hitting my windshield, which might be a manufacturer defect. This is my daily drive vehicle but the crack is in my line of sight while driving and is not safe. This crack happened yesterday while driving and I contacted KIA service department and left a message since it was on a Saturday afternoon.

The panoramic sun roof opens but will not close. it takes 6-12 attempts to get it to close, it will move to where its an inch away from closing then reopen. Kia has recalls for this make and year but says my car is not affected. attempting to get it to close is very distracting and frustrating taking focus away from driving.

Power train incident - • transmission holding gears, jerking between shifts, gear shifted into S mode on its own and stuck there, unresponsive acceleration, locked up steering/inability to turn the steering wheel and total loss of drive power. • happened while merging onto a highway in one of two split lanes for highway access. A merging semi truck in the other merging lane almost ran into me because I could not give it gas. Me and a local police officer who saw me broke down and stopped to provide additional cover, were nearly hit several (6) times from other vehicles and semi trucks due to malfunctions happening. • diagnosed by Kia dealership and was told there was a major electrical failure which caused the electrical oil pump to fail and need a new transmission. Although my VIN doesn’t list recalls, similar issue to the recall on my same year/make/model under NHTSA Campaign Number 21V519. • Warning lamps/messages shown in photos attached. __________________________________ Forward Collision warning incident - • front forward safety system light appeared on dash, then moments later a warning appeared and the vehicle braked on its own detecting a vehicle in front of me when there was not another vehicle in front of me within vision!! • happened while driving in a 55mph zone, a vehicle was driving behind me when this occurred and that vehicle almost slammed into the back end of mine causing a crash. • problem not yet inspected on vehicle due to blown transmission from above incident and inability to start/move the vehicle.

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, the instrument cluster suffered a total system crash into 'Factory Mode,' losing all telemetry. Simultaneously, the vehicle's Forward Collision-Avoidance Assist (FCA) failed to engage. Despite the vehicle being equipped with automatic emergency braking designed to detect and mitigate collisions, the system provided no warning and no autonomous braking prior to striking a deer. ​Post-Accident Failures: Following the crash, Geico Insurance funded a wiring harness replacement at a Kia facility (backed by a Geico Lifetime Warranty). However, the glitches and 'Factory Mode' errors have returned, proving the vehicle's core safety systems remain compromised. ​Safety Risk: This vehicle is non-compliant with FMVSS 101 and 127. The failure of both the speedometer and the autonomous emergency braking creates an extreme risk of further injury or death. Kia Corporate has failed to address this documented accident history.

Tonight was the first time I drive this car in the snow. I was going downhill doing 5 miles per hour, I even downshifted to hold vehicle back, and the brakes totally locked up on me. I couldn't turn the car, it slid straight across the road, at a "T" intersection, and I crashed into a sign, and continued to slide down a hill on someone's property. In all my years driving this has NEVER happened to me. We have been complaining to Kia about the brake system on this car for months. Something is wrong with this car.
