2023 Kia Sorento Complaints

POWER TRAIN,ENGINE — Filed 07/14/2026

I have a 2023 Kia Sorento with approx 60k, purchased new from New Pot Richey Kia. Approx 7 days ago, while driving home from dropping my son at school, my transmission system error warning came on as well as my check engine light. My RPM'S would increased without corresponding acceleration, which meant my transmission, was slipping. I was also experiencing jerking during shifting. In addition to that, my car would hesitate before moving. And I would also experience a slight vibrations at low speeds. All of this would make me feel unsafe when driving my car.

UNKNOWN OR OTHER,VISIBILITY/WIPER — Filed 07/01/2026

The panoramic sunroof on my 2023 Kia Sorento intermittently fails to close. When commanded to close, the glass travels most of the way, then stops or reverses before reaching the fully closed position. It frequently takes many repeated attempts. In some cases the panel will not seat at all until the vehicle is driven over rough pavement, and the resulting vibration allows it to complete closure. The malfunction is accompanied by a loud grinding or scraping noise from the roof assembly during travel. This condition has been present since I purchased the vehicle new. The sunroof has seen very limited use. Safety risk: the glass panel cannot be reliably secured. An open or unseated panoramic panel at highway speed presents a risk of water intrusion, wind loading on an unsecured glass panel, and loss of roof structure integrity. Repeatedly operating the switch and monitoring the panel while driving is a significant distraction from the driving task, and driving specifically to induce vibration in order to force closure is itself an unsafe workaround. Dealer history: I have reported this to a Kia dealership on multiple occasions. I was told there is no defect and that the cause is debris, which is inconsistent with a vehicle purchased new with minimal sunroof use. On one visit the dealer cleaned the assembly as a goodwill gesture. This did not correct the noise or the closure failure. The vehicle was returned to me as repaired while the noise and the failure to close were both still present. Kia issued Technical Service Bulletin BOD125 (Rev 1, 02/27/2017) describing a slow-to-close condition and abnormal closing noise on the prior-generation Sorento (UMa), remedied by cleaning and lubricating the rear guide rails and replacing the rear tilt levers. My vehicle exhibits the same failure mode described in that bulletin. The component is available for inspection on request. No warning lamps or messages preceded or accompanied the failure.

VISIBILITY/WIPER — Filed 07/09/2026

While traveling on a freeway, the front sliding portion of our sunroof exploded outward and upward. Sunroof was closed at the time with no impact present to cause the event. A very expensive repair for something that is clearly a defect of some sort. KIA was contacted and not willing to warranty or help cover.

STEERING,ELECTRICAL SYSTEM,LANE DEPARTURE — Filed 12/10/2025

Since fall of 2025, my 2023 KIA Sorento has repeatedly been in the shop for multiple issues. Most notably, a completely wrecked steering column. This issue was fixed after being in the shop for 12 days. Then in December, I started noticing the shift would lock while in park. I would need to open the top plate and stick an item down into the shifter to emergency release in order to drive. Then all of the electrical components began to state they were no longer working. No cameras, no lane assistance, no forward collision warning, etc etc. Beyond that, all automatic locks, windows and my trunk stopped working. I was locked out of my vehicle in January in CT with my son. My vehicle has now been at a KIA dealership for 5 months awaiting the part to fix my car. All of these problems have been confirmed by their technicians. I continue to pay my $600 a month vehicle payment, as well as insurance as KIA consumer refuses to assist in any way and does not have any answer as to when my vehicle will be fixed. I do not have a vehicle that will fit my family due to this issue. I have asked them to buy back my vehicle, as it is clearly a lemon, but they state I have waited too long to request the buy back under lemon law in CT. NEVER did I think it would be acceptable to be unable to fix a customers unsafe vehicle and refuse to to do anything to help for 5 months at this time and no end in sight. I also have videos it says are too large to send.

ELECTRICAL SYSTEM,UNKNOWN OR OTHER — Filed 06/29/2026

Vehicle Component Affected: Electrical System / HVAC / Blower Motor Resistor Incident Description: While operating my 2023 Kia Sorento, the HVAC system suddenly suffered a complete failure, causing all airflow to cease instantly. A subsequent professional diagnostic inspection by an authorized Kia dealership revealed that the contacts at the blower motor resistor were severely burnt, causing the blower motor relay to burn out. This failure presents two critical safety and fire hazards: Fire Risk: The physical burning and overheating of electrical components and wiring within the dashboard assembly create an active fire hazard in the passenger cabin. Loss of Visibility: The sudden, complete loss of the climate control system severely compromises passenger safety by preventing the vehicle from defogging or defrosting the windshield during inclement weather, presenting an immediate crash hazard. This exact failure mechanism matches the description of Kia Safety Recall SC351 (NHTSA Campaign 25V649) word-for-word. However, Kia has stated that my specific VIN is excluded from the current recall population. Because this identical safety defect is actively manifesting outside of Kia's restricted recall range, I am requesting that the NHTSA investigate an expansion of SC351 to include all affected 2023 Kia Sorento vehicles to mitigate the risk of electrical fires and sudden visibility loss. 06/29/26 Experienced symptoms Inspected and diagnosed on 07/01/26 at JT Kia (Killian Road) Columbia, South Carolina

UNKNOWN OR OTHER — Filed 06/25/2026

Driving down the road and the left rear passenger window exploded. Shatters went everywhere all over the passenger in the back. I went online and looked and this is a hugh issue evidently with some Kias. To me this is really serious issues that Kia is completely ignoring. Someone will eventually get seriously injured bi the glass exploding like it does.

ELECTRICAL SYSTEM — Filed 05/09/2026

EHICLE: 2023 Kia Sorento, VIN [XXX] , currently 48,000 miles. Vehicle has never been in a collision. DEFECT: MASTER POWER WINDOW SWITCH / WIRING HARNESS — OCCUPANT EGRESS HAZARD The driver's master power window switch fails intermittently, causing simultaneous loss of all window operation and electric door lock function. When this occurs, occupants cannot operate any window or unlock any door electrically until the condition resets, typically by opening and closing the driver's door. The condition was first reported to Arapahoe Kia at 24,859 miles on 11/08/2024 (RO 208018) and again at 25,050 miles on 11/15/2024 (RO 208449). On the 11/15/2024 visit, the dealership confirmed the defect on customer-supplied video and performed a full diagnostic including pin tension testing on connector D01, power, ground, B-CAN continuity testing, and a wiggle test of the harness. The dealership's written conclusion on the repair order: "we've determined that the harness is probably not the issue and it will need a new master switch." The master switch was not ordered or installed, and the vehicle was returned with the defect unresolved. The condition continues to occur intermittently as of the current 48,000-mile reading. SAFETY IMPLICATION: This defect creates an occupant entrapment and egress hazard. In a fire, submersion, or crash event where the mechanical door release is inaccessible, inoperative, or where occupants are incapacitated, simultaneous loss of window operation and electric door lock function eliminates secondary egress options. The defect is intermittent and unpredictable. The vehicle remains within the 5-year / 60,000-mile basic warranty period.

FUEL/PROPULSION SYSTEM — Filed 05/09/2026

VEHICLE: 2023 Kia Sorento, VIN [XXX] , currently 48,000 miles. Vehicle has never been in a collision. DEFECT: FUEL FILLER DOOR ACTUATOR WITH NO EMERGENCY RELEASE — STRANDING HAZARD The fuel filler door actuator fails to release on demand intermittently. When the actuator fails, the door must be pried open with tools or force, which is inconsistent and not always possible. The dealership service advisor has stated that this model is not equipped with any emergency release mechanism for the fuel filler door. With no emergency release, the actuator is the only mechanism by which the fuel door can be opened. SAFETY IMPLICATION: An intermittent actuator failure with no backup release mechanism creates a stranding hazard. If the actuator fails when the vehicle is low on fuel — particularly in remote areas, in cold weather, at night, or in emergency situations requiring refueling to reach safety or medical care — the vehicle cannot be refueled and becomes immobilized. This is a single-point-of-failure design on a system required for vehicle operation. The condition has been reported to the dealership and remains unresolved. The vehicle remains within the 5-year / 60,000-mile basic warranty period. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE — Filed 02/06/2026

Vehicle exhibits repeated brake pulsation and vibration under normal braking conditions, affecting braking performance consistency. The issue began at approximately 10,000 miles and has progressively worsened. The vehicle currently has approximately 30,000 miles. The pulsation is felt through the steering wheel and brake pedal during moderate braking from highway speeds and occurs consistently across multiple driving conditions. The condition is significantly more pronounced when using the vehicle’s adaptive cruise control system. During normal operation, the adaptive cruise repeatedly applies the brakes automatically, and this consistently produces increased vibration and uneven braking response. This indicates the issue occurs during normal vehicle operation rather than abnormal use. The repeated pulsation creates inconsistent brake feel and may affect stopping performance, particularly during repeated or sustained braking events. This raises concern regarding braking reliability and stopping consistency, especially in traffic conditions where adaptive cruise control is actively managing following distance. The condition has steadily worsened over time and is present during routine driving. It is not limited to high-speed or heavy braking scenarios. A manufacturer Technical Service Bulletin (TSB CHA126V) exists for this vehicle model addressing front brake disc judder. The symptoms described in the bulletin match the condition experienced in this vehicle. Given the early onset, progressive nature of the issue, and the involvement of system-controlled braking (adaptive cruise), this condition appears to be related to component performance or design rather than normal wear. Kia response .. Dear [XXX] , Thank you for contacting Kia Customer Care. We do not see that bulletin related to this VIN, as such, any repairs recommended would be the responsibility of the vehicle’s owner.
