2023 Kia Sorento engine problems

Filed Oct 18, 2026 · Engine · TX

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.

When traveling up an incline or when gassing the car to accelerate quickly my car registers a spike in heat causing my car to go into limp mode creating a dangerous situation where I can not accelerate at the cars normal rate. When I lift off the gas the temperature normalizes and the car goes back to normal. I have taken the car to two Kia dealerships and they both charged for an assessment and gaslighted me saying they don’t see the issue even tho there are reports all over the internet with the same issue. I also presented a video showing the problem. Two years ago around 35000 miles I had the same issue and the dealership replaced the itm module which corrected the problem. The problem returned at 82000 miles and now they are saying my car is fine which it is not.

My 2023 Kia Sorento has experienced repeated failures involving the engine, transmission/powertrain, and electrical wiring system. The vehicle has been inspected and repaired multiple times by authorized Kia dealerships, including Kia of Round Rock and Clay Cooley Kia in Irving, and the repair history and vehicle are available for inspection upon request. The most serious incident occurred on XXX, while I was driving on the [XXX]. The vehicle suddenly lost acceleration, began smoking, and experienced a catastrophic engine-related failure, creating a serious safety concern while I was traveling on a high-speed roadway. The vehicle had to be towed to Clay Cooley Kia, where it remained for approximately three months and the engine and related components were replaced. After receiving the vehicle back on XXX, a significant oil leak developed approximately five days later. The vehicle was returned for service, the problem was confirmed, and it ultimately required a transmission replacement. On approximately XXX, multiple/all dashboard warning lights illuminated, and Kia subsequently replaced the wiring harness. The vehicle continued to experience problems and was towed to Kia again. In XXX, Kia determined that another transmission replacement was necessary. The vehicle has now had three transmissions associated with it, in addition to the replacement engine and wiring harness. XXX, the vehicle is still malfunctioning despite being on its third transmission. Current symptoms include the RPMs suddenly surging/revving higher than expected, jerking while driving, and a noticeable delay between pressing the accelerator and the vehicle accelerating. These symptoms create a safety concern because I cannot confidently predict how the vehicle will respond when accelerating, merging into traffic, crossing an intersection, or traveling at highway speeds. I am concerned that the repeated engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On multiple occasions, my 2023 Kia Sorento has experienced an intermittent failure where numerous dashboard warning lights and alerts illuminate and the engine will not start. During the failure, the brake pedal becomes very stiff and the vehicle cannot be shifted out of Park. The problem is unpredictable and has left the vehicle disabled. The vehicle was taken to a Kia dealership for diagnosis. The dealer initially stated that the battery was not properly secured and was moving around, possibly contacting nearby electrical components. They told me the issue had been repaired. However, when I returned to pick up the vehicle, the exact same failure occurred again in the dealership parking lot before I was able to leave. The warning lights came on and, after the vehicle was turned off, it would not restart. The dealer has therefore been able to directly observe the repeated failure. The exact component causing the malfunction is still unknown. I am concerned that this may be an electrical or grounding issue and that the vehicle could become disabled unexpectedly while in use.

The vehicle intermittently fails to start in two different situations. First, when the auto Stop/start system shuts the engine off while the vehicle is stopped anywhere, the engine sometimes refuses to restart, leaving the vehicle immobilized. Second, there are occasions when I park the vehicle, turn it off normally, and upon returning, the engine will refuse to start.

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.

Faulty fuel injectors are causing consistent engine misfires and occasionally causing the check engine light to illuminate and for the vehicle to reduce power greatly. This poses a great safety risk to both myself and other drivers on the road because in the event of a large misfire, my vehicle suddenly slows and I have to navigate to the shoulder of the road. A Kia dealership has confirmed that the cause of these misfires is due to a faulty fuel injector that begins to work inconsistently above 3000 RPM. This issue began shortly after the vehicle was purchased in 2023, but due to the dealerships inability to replicate the issue it went without correction. In the recent year, this issue has increased greatly and it is now a consistent issue and this is why it was able to be diagnosed now. This is a very common and widespread issue amongst other individual with vehicles with the same engine.

I am submitting a vehicle safety and certification concern regarding a 2023 Kia Sorento Hybrid that was marketed and offered for sale as a Kia Certified Pre-Owned (CPO) vehicle by Shawnee Mission Kia, 7951 Shawnee Mission Pkwy, Mission, KS 66202. On [XXX], during an in-person inspection of the vehicle prior to purchase, I observed conditions inconsistent with expected Certified Pre-Owned inspection and preparation standards, including inverter coolant below the minimum level, engine oil materially above the normal operating range, and deteriorated windshield wiper condition. A third-party witness was present during the inspection. Because the vehicle was being represented as Certified Pre-Owned, I requested the vehicle’s CPO inspection checklist and supporting inspection documentation from dealership personnel. The requested documentation was not provided despite multiple follow-up requests. Subsequent written communications from dealership management acknowledged failures in dealership standards and handling related to the matter. After a formal complaint was submitted to the dealership’s corporate parent, the dealership’s General Manager responded in writing that an internal review had been initiated concerning CPO preparation and documentation practices. The requested inspection and service documentation were still not produced. The dealership later confirmed in writing that the vehicle “has since sold.” I am submitting this complaint because the vehicle was represented to consumers as Certified Pre-Owned despite observed maintenance and inspection concerns affecting vehicle condition and safety-related systems, while supporting certification documentation was not produced upon request.

Immediately after a dealership-performed warranty repair, the vehicle experienced a severe safety‑critical failure at highway speed. The vehicle began shaking violently, produced loud knocking and impact noises, and metal pieces fell from the underside. The failure occurred without warning and created an immediate loss of safe drivability. The dealership later documented that an engine mount (‘lower dog bone mount’) had not been torqued to specification, which allowed the engine to shift back and forth under load. This improper torque caused the violent shaking, metal impacts, and falling metal. The problem was confirmed by the dealership, but no corrective repair was performed. Only a single bolt was re‑torqued, and no inspection was done to determine the extent of damage, the source of the falling metal, or the cause of the knocking. The vehicle was returned in an unsafe condition and has not been driven since. The vehicle had to be towed directly from the highway due to the severity of the failure, and it was delivered straight to the dealership because it was unsafe to operate. The vehicle remains available for inspection.
