The problem is ongoing and has occurred on three separate occasions. Starting when the vehicle had been driven approximately 20,000 miles. The problem occurs without warning. the vehicle well be performing as expected then a warning light will come on next every warning light on the dash comes the vehicle loses power in a extremely short period of time. it can be steered and the brakes work. The problem has occurred in heavy traffic creating a harrowing experience. Once I am in a relatively save place I turn the vehicle off for a period of time. I then restart and the warring's clear like a computer is rebooting. I have been two dealers neither can identify the problem.

During normal operation the vehicle will randomly decelerate (no brake lights). This has happened on the highway and on city streets. I repeat on the highway this vehicle will go from 75mph to 40mph with no lights or warnings. The issue happened with my wife and child in the car and I was able to replicate the issue. I refuse to put my family in the car at this point. The Dealership says they cannot replicate the issue but is also lying about driving it diagnostically. The issue is video documented on two occasions. Since vehicle is under warranty it was brought to the dealership both times and have had zero resolution. During its last visit I was without the car for a month. I Contacted KIA corporate who denied a buy back. This vehicle will undoubtedly kill or injure my family or more if driven. I have been responsible and not done so to protect the public. But I need the car. Car is available for inspection at anytime. Videos available upon request.

The 12-volt battery system repeatedly collapses while the 2023 Kia Sorento Plug-in Hybrid is parked, leaving the vehicle completely immobilized: the doors will not unlock/open normally and the vehicle cannot be started, even though the high-voltage hybrid battery and fuel are ample. On November 2, 2026, after six days parked, the 12-volt system measured approximately 6 volts, about half of nominal. The vehicle could not be revived by 14+ hours on a battery maintainer; on November 3, 2026, roadside assistance revived it with a jump pack applied for about 1.4 seconds, confirming a system failure rather than an energy shortage. The defect has previously locked the owner out of the vehicle at -12 degrees Fahrenheit in upstate New York, a safety hazard in cold climates. The owner's instrumented findings, reported to Kia America in writing on February 9, 2026 and again November 2, 2026, show persistent parasitic draw during idle states, inconsistent charging of the 12-volt battery by the DC-DC converter, and no logic to re-energize the 12-volt system from the charged high-voltage battery. Kia has provided no substantive technical response. The vehicle/component is available for inspection upon request. No crash, no fire, no injuries. Manufacturer and dealer were notified in writing.

I am filing a formal vehicle safety complaint regarding my 2023 Kia Sorento, purchased new in December 2023. My vehicle has experienced intermittent, unexpected engine stalling and loses acceleration while driving requiring to turn off an back on. This creates a serious safety risk because the vehicle can unexpectedly lose propulsion while in traffic, potentially resulting in a collision. The vehicle was taken to an authorized Kia dealership for evaluation several times over the past year. Despite the reported malfunction, the dealership has been unable to reproduce or identify the cause. The vehicle has not been repaired, and the underlying safety concern remains unresolved. I opened a case with Kia Corporate Customer Care and have repeatedly requested that this safety issue be escalated for further investigation. However, Kia has not provided a resolution, and my requests to speak with a supervisor or higher-level representative have been refused. The dealership is now requesting the return of its loaner vehicle on October 30, 2026, despite the unresolved safety concern. Kia has refused to authorize continued alternative transportation. I do not feel safe operating this vehicle because I cannot predict when it may stall or shut off again. I am concerned that this malfunction could result in a serious accident, injury, or death. I am requesting that NHTSA investigate this potential safety defect to determine whether other Kia Sorento owners have experienced similar engine shutdowns or unexpected losses of propulsion. The dealership’s inability to reproduce this intermittent problem should not be considered proof that the vehicle is safe to operate.

Subject: Request for Review of Potentially Related Electrical Overheating – Kia Sorento HVAC Harness Recall SC351 / NHTSA 25V649 I am requesting that NHTSA review an electrical overheating issue involving my Kia Sorento and consider whether it could be related to the existing HVAC blower-motor resistor harness recall, SC351 / NHTSA 25V649. My vehicle experienced overheating at a terminal on the main relay in the under-hood fuse box. The overheating spread to and melted part of the fuse box. Kia inspected the vehicle in person and informed me that the overheated relay terminal belongs to a different circuit from the HVAC resistor harness involved in the recall. I understand Kia's position that these are separate circuits. However, I have not received a detailed technical explanation identifying the root cause of the relay terminal overheating or explaining the basis for ruling out any relationship to the recalled wiring defect. Kia has offered approximately $2,200 toward an estimated $3,900 repair through a goodwill program, leaving me responsible for approximately $1,700. I am concerned about both the safety implications of the electrical overheating and whether the problem could be related to a known wiring-harness defect. I am not asserting that the recalled HVAC harness definitively caused the damage. I am asking NHTSA to consider whether this incident warrants further review, whether similar failures have been reported by other Kia Sorento owners, and whether the existing recall adequately addresses the relevant safety defect. I can provide the vehicle identification information, recall information, photographs of the damage, Kia's written communications, and the repair estimate. Thank you for reviewing this potential safety concern.

My 2023 Kia Sorento has experienced continuous mechanical failures, including a serious engine fire in December 2025 while I was driving on the [XXX], which put my life at risk. Following that incident, my vehicle remained in the shop for nearly three months while the engine and related components were replaced, only to experience another failure in March 2026 requiring a transmission replacement, followed by electrical issues in April requiring a wiring harness replacement. In June 2026, my vehicle broke down again and required yet another transmission replacement, leaving me without my vehicle for several additional months. [XXX], my vehicle failed AGAIN while I was in Houston and had to be towed, proving that nearly a year of extensive repairs has failed to resolve these ongoing mechanical issues. This vehicle is a serious safety concern, and I have completely lost confidence in its reliability, especially after experiencing an engine fire, repeated breakdowns, and dangerous acceleration issues. I have continued making monthly payments on a vehicle that has spent more time in the repair shop than in my possession, causing significant financial strain, stress, and inconvenience. After nearly a year of unsuccessful repair attempts, I am demanding an immediate and permanent resolution, including a vehicle buyback or replacement, as I should not be expected to continue driving a vehicle that repeatedly jeopardizes my safety.

The vehicle experienced a sudden transmission malfunction while operation on public roads. The check engine light illuminated on the dashboard, and a diagnostic scan from the app revealed active error code P1C2D03. This specific component failure looks like it relates directly to Kia Safety Recall SC250 (NHTSA Campaign 22V760) regarding the 8-speed Dual-Clutch Transmission (DCT). Although my specific vin shows no active recalls. The failure presents an immediate safety risk as it causes an abrupt, unexpected loss of all motive power while driving in traffic.
