2023 Kia Sorento: multiple warning lights

Filed Sep 9, 2026 · Engine · TX

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.

All lights came on the dashboard including the check engine light and I could not accelerate. I had to pull over and turn car off and on to get it to accelerate. It poses a very serious threat as you can not accelerate at all and can be rearended. Kia has fixed the throttle twice and have told me 2 other times they can not replicate the issue. It clears out by the time I am able to bring it to the dealership. This issues has happened 4 times starting at 9,000 miles and most recently at 21,000 miles.

Upon starting the vehicle, it flashed several warning lights that were not on the day before. Including popping codes up on the infotainment system and urging me to schedule a service with KIA. Upon looking up the codes it states HVAC issue, when calling to dealership to schedule a service for it (while it is still barely under warranty) they let me know it might not be covered. That’s when I found out there is a recall only for certain VIN #’s for the exact same issue. My car won’t even drive because the electrical system is being affected. Windshield wipers going crazy, lights not working, AC/heat not working, the emergency braking system braking out of nowhere, the lane departure pulling the wheel while driving without cause. I don’t even feel safe driving the vehicle anymore. Kia needs to have a recall on this that alerts the vehicles owners because I had no clue that there was a potential fire hazard due to faulty wiring.

As a result, I no longer feel safe operating the vehicle. In July 2025, I formally requested that Kia Corporate initiate a buyback of the vehicle, rather than returning it to me following another attempted repair."

I had just entered the highway and reached highway speed of 70 mph. Without any warning, the engine died, all of the dashboard lights came on, and I was unable to accelerate. Thankfully I was in the right-hand lane and there was an exit ramp a short distance ahead. The car decelerated as it had no power, and cars behind me were honking. I was able to exit the highway and coast into a parking lot just off the frontage road. Had I not been able to get off the highway, the vehicle would have been stalled in fast-moving traffic, and a pile-up could have easily occurred. I turned the car off using the push button start/stop, waited several minutes, and restarted the car. The check engine light was on and the car diagnostics system reported an issue with the "engine management system." Upon clicking the details link, the diagnostics system further stated "A possible condition with your Engine Control System has been detected. A full system check is recommended to be done soon. Please contact your local dealership to schedule an appointment." I took the car to a local Kia dealership, and they stated they could not recreate the problem. They reported they "inspected the vehicle for DTC's and found code PO65312 in history." They cleared the code and reported, in writing, that "no issues found during test drive, vehicle currently operating properly, no further action taken" and gave the car back to me without fixing anything. They stated it may need to be diagnosed for longer ext diag time. The vehicle is available for inspection, and I would appreciate any help I can get as I got no help at the dealership.

When attempting to start the car, the engine will not start and every alert system and dashboard light turns on. The car is undriveable when it does this. It takes 5-10 minutes of turning the car on and off before it stops and is drivable again. It does not happen every time and seems to be random. This has happened 5 times. An additional 6th time this same issue happened while I was driving - all of the dashboard lights went on, and every alert / warning turned on (forward collision, lane warning, etc). The steering wheel also became stiff and extremely difficult to turn. I have been attempting to work with 2 different Kia service departments and their corporate escalations department without luck. They are unable to replicate the issue and are planning to give the car back to us. After seeing so many similar or same issues reported on various forums I am filing a the federal safety agency claim.

I bought a 2023 Kia Sorento SX with 11 miles on the vehicle in June of 2023, On 7/17/23, within a month and a half of driving it, it would lose all power and would not respond to excelleration, whereby coasting to the side of the road. All warning lights would come on, 3 codes popped up, one of which is the malfunction of the engine. I would turn it off and back on to reset the computer and it would drive. I took it to my local Kia service department and they cleared off the codes and couldn't recreate or duplicate the problem. On 8/23/23 I experienced the exact same experience the same scenario, but this time I could barely pull over it had loss of power and I was about to drive through an intersection. Took it back to service they performed a complete check without success they kept it for 2 weeks to try and duplicate the problem, wasn't fixed. The 3rd time on 5/06/24, same problem, they still don't know what causes the car to lose power. I am concerned that the car will cause a fatality to myself, my family, or to another motorist. This car is not safe to drive because the computer systems shut down while driving and it is sporadic and unnerving when it happens.

Purchased brand new 2023 Sorento on 12/30/23. On Jan 14th, with less than 300 miles on it, had 1st incident. All lights on dash came on said Engine control system, lost all ability to accelerate. Had to get out of traffic, as safely as I could. Turned car off and waited 5 min. Turn car back on, check engine light stayed on but could give gas. Took to dealership and a code was stored in history, engine control module. 3 days later took it back to get fixed and they could reproduce problem or get any code. Put flight recorder on, drove it for 11 miles, nothing. Said they can't fix without a code. On Feb 17th, with 1500 miles, same situation. All lights on dash, cannot give any gas. Extremely dangerous in traffic. Got off road and on display it said it performed 7 checks. All showing good except Engine Management System. Shows condition with engine control system and take to dealership immediately. It was a Saturday, service was closed. Check engine light stayed on Saturday and all day Sunday. Monday, check engine off. Took to dealership, no code found. This is a brand new car and has has same problem twice now. They are saying they need a code to fix. So now I'm driving a ticking time bomb, a death trap. Scared to drive on interstate or anywhere with heavy traffic. When you loose ability to control cars speed, that's EXTREMELY dangerous. I dropped car off at KIA and will NOT pickup until they can tell me what's going on with my brand new car. Why KIA put a safety feature that "limp mode" stops the car from accelerating is beyond me. This is so scary and disappointing.
