What 107 owners told NHTSA about the 2023 Kia Sorento Plug-in Hybrid

Engine- car turn off - lights were still on, car restarted - no icons on dashboard

NHTSA ODI 11740793

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.

UNKNOWN However multiple times the front end of the vehicle starts shaking when I try to break up especially on the highway. The dealership claimed to have repaired it once and shortly after it happened again. When I took it in they first looked and said the parts was ordered but nothing was done then came back and said oh yes it was done then refused to fix it without a charge so I had to pay to repair it since I feared that the brake would give out if I drive it. The other issue was the check engine light just popped up check engine while driving on the highway, when I take it in they are stating that I may have left the gas tank open which is absolutely false. They cleared it but could not or neglect to explain why it was on. All these incidents occur while on highways never in the general local areas.

Was driving on Dallas North Toll way when my vehicle lost acceleration. Had to pull over and engine started smoking and lit a flame under the hood. Car is now at Clay Cooley Kia in Irving, TX. Car has been there for over two weeks and I still have no answers or information regarding the plan to fix it. Major dealership delay and all they keep saying is “Waiting on a Kia Engineer to come out but we don't have a date.”

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.

While driving vehicle looses throttle power, goes into limb mode. Does not throw any codes. Turn the car off then back on and drives fine for a little bit. Has happened numerous times. Multiple trips to the dealership but since no codes pop up nothing can be fixed. Major safety issue!!!!

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.

The vehicle was purchased new. From day one, there were issues. When it was delivered from the factory, it was discovered to be partly unpainted. This raised quality concerns. So far, the most serious has been that the motor blower failed at approximately 29,700 miles. This resulted in the vehicle filling with noxious fumes. It then had to be abandoned on the side of the highway. This led to a fire dispatch and later urgent care visits. Prior to towing, it was discovered that the AC was not working and the engine coolant reservoir was at ~ 1/4 of the minimum line. Ultimately, the vehicle was towed to King KIA. They held the vehicle for 2 weeks. They drove the vehicle 16 miles. However, they did not diagnose the problem. The only action that they took was to refill the engine coolant reservoir. Prior to pick-up, we notified the KIA Customer Service Escalation Case Manager in writing that the vehicle had not been fixed and continued to represent a safety risk to our family. They took no further action. After pick-up, the vehicle was driven approximately 35 miles before the smoke started to fill the engine cabin. It was taken to two independent mechanics along the side of the highway. One was Vienna Auto Care and the other was Jiffy Lube Auto Care. Both identified that the motor blower resistor had likely failed. The JLAC manager also identified white material on the engine manifold believed to be engine coolant. All was documented in writing. The vehicle was towed back to King KIA. Prior to towing, the JLAC manager told us that melted motor blower casing was highly toxic. (Later, the KIA Case Manager informed us that he would admit that our family was put at risk by being told to pick-up the unfixed vehicle.) He also told us that if the motor blower failed then it likely was not an isolated case. This time, the motor blower failure was reproduced. However, the engine coolant issue has yet to be resolved. We are now being instructed to pick-up the car again.

This was an alarming situation. I was taking my wife for a cancer treatment in our 2023 KIA Sorrento with 2600 miles on it. The instrument panel showed a A with a circle around it, blinking continuously. I was going up a grade in a town and the car would not accelerate. All of a sudden the engine SURGED the brakes would not stop the car, I put it into neutral and went into a parking lot. If there would have ben a car in front of me or no place to pull over there would have been a serious accident. I called the KIA dealership and took it in for a diagnostic test. Nothing wrong with car was their answer. In the mean time I am afraid to drive the car. I am [XXX] and reflexes are not as good as they were [XXX] .

Twice while driving on the highway the engine power went off and all the safety lights flash and I could not accelerate. I was able to pull Over in neutral and restart the engine. When taken in for inspection, no problems were found. It happened again in June after the 7500 mile inspection on May 9th. This issue is life threatening as it could easily cause a fatal crash if I was not in the right lane, on flat ground, with a shoulder. There was no warning light.

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.

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.

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.

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.

NHTSA ODI 11570005

1. I have been complaining about the vehicle turning off by itself. No one is listening to me or telling me what is causing the problem. I have numerous witnesses when the car turns off by itself. It isn’t safe. It could cause a deadly accident. No it’s not the auto shut off either. I have to put the car in park and hope it restarts each time. 2. When auto shut off is in use the vehicle stalls leading it to act like it’s trying to get fuel to move and turns off. I’ve come too close to having accidents. I never know when it will do it. Sometimes I don’t drive it because I don’t want to be held liable for causing an accident and harming somebody's life. 3. I had been complaining to them that I smelled something burning but I couldn’t identify it. I asked them to keep my car and check it out and they refused. While driving in the hottest summer the AC goes out. I immediately took it to the dealership. The worker said we can’t fix it. It'll be a week before they will take my vehicle. The lady was rude and said go to another dealership. It was too hot not to have AC then on top of that it rained the rest of the week and I wasn’t able to work because I couldn’t defog my windows to drive. It finally stopped raining and I was able to get another dealership to check it out and they told me something had burned up that makes the AC work ( I have the paperwork). If they would have checked the car like I asked when I first started complaining about smelling the burning smell this could have been avoided. Also, I don’t get notifications about recalls via mail, phone, call, email etc.
