2023 KIA SORENTO Power Train Problems

I purchased a new 2023 Kia Sorento in February 2023 from Ken Garff Kia Avondale. Since shortly after purchase, the vehicle has experienced repeated electrical and mechanical failures that substantially impair safety. In July 2023, the vehicle began displaying flashing lights, dashboard error messages, and system malfunctions while driving, despite no collision or visible damage. The air conditioning system malfunctioned and blew hot air even when turned off. The dealership stated a front sensor was “damaged” and not warranty-covered, despite no visible damage, and verbally indicated that many other customers were experiencing similar issues. Repairs took nearly four months, during which Kia Corporate engineers were involved. The issue persisted despite repairs. In December 2024, the vehicle began displaying repeated transmission system error warnings, often within the first 5–10 minutes of driving, causing significant loss of speed and drivability. After multiple service visits, the vehicle required a full transmission replacement in July/August 2025 under warranty. Despite this repair, the same transmission errors returned in December 2025. More critically, the vehicle then experienced multiple sudden and complete electrical shutdowns without warning, including: Shutting off entirely while stopped at a red light, requiring a jump start All screens going black and the vehicle failing to restart Restarting only after being left parked for several minutes These events occurred without any battery or system warning indicators and created a serious safety risk, including risk of being stranded or disabled in traffic. The issues have been documented with photos, videos, repair records, and written communications. Due to the ongoing and dangerous nature of these failures, I am reporting this as a vehicle safety defect.

Incident #1: [XXX] The vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 MPH with oncoming traffic from both the East and West as I was turning West from a North Bound Road. On coming traffic was traveling between 45 and 50 MPH. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 MPH speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the Kia of Round Rock dealership November 17th. The car remained at Kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to Kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [XXX] Vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (No traffic was visible.) The car would not accelerate more than 20 MPR, the speed limit was 55 MPH. For the 1.5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 MPH.

The contact owns a 2023 Kia Sorento. The contact stated that while the vehicle was parked, the gear shifter was shifted into drive, the accelerator pedal was depressed; however the vehicle failed to accelerate as intended. The contact stated that the vehicle failed to move forward. No warning lights were illuminated. The contact stated that the failure had occurred more than five times within a month. The failure occurred after a previous repair was performed by the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that previously, while the vehicle was parked on a hill, the gear shifter was shifted into reverse, and the vehicle rolled forward and crashed into a curb. The vehicle was taken to the dealer and was repaired. The contact was informed that the failures were not failures but instead the normal function of the vehicle. The contact submitted a Lemon Law claim and was advised to contact the NHTSA Hotline to report the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 21,700.

Mileage: 21,700

on [XXX], the check engine light came on solid. My car is just 2 years old, only has 22K miles, and is currently under warranty, as it is a leased vehicle. According to Auto Zone, it was a "speed sensor". On 7/25/25, I was able to get an appointment with Garvey Kia of Queensbury, NY and the fault code is the "input turbine shaft speed sensor B circuit range for performance". The service technician told me that it is not able to be accessed, as it is internal, and it is not serviceable. My safety and the safety of others were at risk because the car would go "limp" when accelerating, there was harsh and delayed shifting, erratic RPM readings, and no power when accelerating. This inability to accelerate causes problems in traffic and when trying to get through intersections or out of side streets when acceleration is imperative. Yes, the car has been inspected by the Kia dealership. This same exact thing happened on [XXX], in which Destination Kia of Albany had by car for over 4 weeks to replace the transmission. At that time, the car had under 10K miles and was not even a year old. At that time, they put a refurbished transmission into the car.

When I start driving, there’s a lot of hesitation like it’s going to stall and it also does this going up hills or mountains? I was on the interstate and there was a line of cars behind me and my car started to hesitate and almost stall, causing all cars behind me to break to not cause a domino effect accident I have reported this to the Kia dealer and knowing that there’s a lot of DCT problems that are posted all over the Internet they are saying there is no problem with the car upon doing research again there is a lot of DCT reporting of Kia’s not just my Sorrento please do some research on this and help me. We just bought this car. There is 13,000 miles on it. It should not be doing this and again I’m going to a different Kia to see if they say the same thing. Below you ask for a date that this happened there is too many dates to enter, but I will try to enter the very first one that we experienced.

Transmission Warning Indicator appears on Dashboard Cluster and vehicle bucks and stalls and won't shift properly. Dealership found Transmission was never filled properly and below specifications according to Kia Service and was verified the fluid level was extremely low and not filled to specification from factory. The dealership filled transmission to proper level and test drove vehicle. Issue seamed to be fixed. But now a month later same transmission is is happening with Transmission warning Indicator and vehicle bucking and not shifting properly causing erratic vehicle behavior and safety issues.

Car is a huge safety issue. Seems to be DCT transmission issue. Car gets stuck in first or second gear and revs all the way up. Happened multiple times getting on highway or at intersections. This has almost caused multiple accidents for me. You can push the pedal to the floor and it won’t do anything. The only temp fix is turning car off and back on.

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.

CURRENT MILEAGE 6,776 miles -Purchased the vehicle and on two occasions the AEB Emergency brake system came on twice without any cars around- Also, twice the engine shutdown light came on and acceleration has stopped on me and the vehicle stalled, which is dangerous if Im on the parkway or road where I cant pull over like a bridge. NICE LOOKING CAR BUT DONT BE FOOLED- A 🔴RECALL NEEDS TO BE SENT TO PROTECT OTHERS FROM A CRASH IMMEDIATELY.

As I was driving the car it suddenly lost power… then all warning and sensor lights came on in the dash. I pulled the car over and restarted and the engine turned on but would not engage to drive. It was stuck. Multiple engine and transmission warning codes appeared on my Kia app for the car. Kia’s response to resolve has been non existent. I am fearful for my safety if this happens again. It’s the second time.

Engine light came on and I don’t have 30,000 miles on my car. The service tech informed me that they’ve seen this and Kia had not issued a recall

On [XXX] while driving and in the process of changing lanes, as I accelerated on the brakes, my Vehicle gave a sudden jerk, at first I figured it was due to the road being wet, but on [XXX] while driving to NYC on [XXX] as we all know we all have to keep up the speed, once again during accelerating my vehicle repeated the same sudden jerk and continue for most of my ride, I brought into KIA on [XXX] with the end result being they did not find this issue, as well as my ongoing issue of my engine light that has been coming on and off for about 5 months now. I do believe my vehicle is having some kind of issue with the transmission and gears are not kicking in during the acceleration process may I add this is on the highway. My vehicle is a 2023 which I purchased in Aug of 2023 and have been in the dealership for shaking during braking engine light on and now gear delay with no resolution to all issues, I will be contacting the Manufactured as my next step in the horrible processes.

Transmission Oil light came on and the vehicle lost power. It was determined that the Transmission was faulty with only 3800 miles.

Transmission problem arised on/about 9/15/23 and 3,000 miles. There is a distinct shudder when shifting through lower gears, more recently, on/around 4,000 miles l, shudder is growing worse, and there is intermittent problems at highway speeds. This is very dangerous, and could cause an accident/injury at any time. I have been to my local Kia dealership 3 times now, who have flight recorded and concurred with me that its the transmission failing, but have been sent home every time with "we don't know exactly what it is, so keep driving it". These symptoms are very similar to the 2021 model years dct transmission recall problems. I know of others with this same problem, and Kia needs to be held liable asap.

The contact owns a 2023 Kia Sorento. The contact stated while driving 70 MPH, the vehicle independently decelerated with the transmission error warning light illuminated. The contact was able to push the vehicle to the side of the roadway. The vehicle was towed to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was 12,000. The VIN was not available.

Mileage: 12,000
