2019 Kia Sorento: sudden loss of power

Filed May 20, 2026 · Engine · AZ

My 2019 Kia Sorento equipped with a Theta II engine entered limp mode and displayed a flashing check engine light along with an active P1326 diagnostic trouble code. The P1326 code is a proprietary Kia/Hyundai specific code that can only be generated when the Knock Sensor Detection System (KSDS) software update is present on the vehicle. This software was developed and distributed by Kia specifically to detect Theta II engine bearing failure and rod bearing wear before catastrophic engine damage occurs. The presence of the P1326 code is confirmation by Kia's own proprietary detection system that this engine is experiencing the exact failure pattern associated with the Theta II engine defect. The vehicle was towed to an authorized Kia dealership. The dealership refused to perform a BTC test or enter the vehicle into Techline, citing that the VIN does not appear in the Theta II settlement database. Kia America customer care has also denied coverage. The vehicle remains inoperable. Safety risk is significant. The Theta II engine defect has been directly linked to engine fires in Kia and Hyundai vehicles. Limp mode and sudden loss of power while driving creates serious risk of accidents, injury, or death to the driver and other motorists. The 2012-2019 Kia Sorento is a model year range specifically identified in Theta II multidistrict litigation. Kia's own KSDS software flagging a P1326 code on this vehicle while Kia simultaneously denies any defect-related coverage is contradictory and raises serious safety concerns for owners whose VINs were excluded from settlement but whose vehicles are exhibiting identical failure symptoms.

I am submitting this complaint regarding a 2019 Kia Sorento that has experienced recurring oil loss/oil starvation and engine-related issues that I believe may present a safety concern. I purchased the vehicle used with approximately 45,000 miles. Since ownership, the vehicle has experienced repeated incidents involving low or nearly empty oil levels despite regular maintenance and monitoring. The vehicle previously underwent an oil consumption evaluation, however the issue continued afterward. During one event, the vehicle was reportedly found approximately three quarts low on oil. More recently, the vehicle again appeared to have little to no oil visible on the dipstick and began exhibiting drivability and engine concerns including grinding/banging noise during acceleration, intermittent timing/tensioner-type noise, misfires on cylinders 1 and 2, exhaust smoke, and strong oil-burning odor from the exhaust. Due to concern over possible engine damage and reliability, the vehicle was returned to the dealership for further diagnosis and repair. The dealership replaced ignition coils and spark plugs and road tested the vehicle extensively. While the vehicle is currently operating, I remain concerned that the underlying oil consumption/oil starvation condition may not have been permanently resolved. My concern is that repeated oil starvation conditions could potentially lead to sudden engine failure, loss of power while driving, or other safety-related issues. I am requesting that this issue be reviewed to determine whether similar complaints or defects exist involving oil consumption, oil starvation, or related engine failures in this vehicle.

Vehicle: 2019 Kia Sorento Issue: Engine Failure / Safety Concern Complaint: I am filing a complaint regarding a 2019 Kia Sorento that experienced sudden engine failure after clear warning signs that created a serious safety concern. The vehicle began making a loud ticking/knocking noise that progressively worsened over time. While driving, the vehicle struggled to accelerate and lost power. The noise became louder when pressing the gas. Shortly after, the vehicle shut off completely and is now unable to start at all. This failure occurred without any warning lights appearing on the dashboard, including no check engine light, which prevented me from knowing the severity of the issue in advance. After contacting Kia, I was informed that there were multiple recalls on the vehicle that were not completed. However, I was never notified of these recalls as the current owner. I was told that recall notifications were sent to the previous owner, and no effort was made to notify me directly. Kia has refused to assist with the engine failure, stating that recalls must be completed first. However, the vehicle is now completely inoperable and cannot be driven to complete recall repairs. Requiring a non-running vehicle to complete recall updates is unreasonable and places consumers at risk. This situation raises serious safety concerns because: The vehicle lost power while in operation, creating a dangerous driving condition There were no warning indicators prior to failure The engine failure appears consistent with known issues involving Kia engines I am requesting that this matter be investigated, including Kia’s handling of recall notifications and their refusal to assist with a known engine failure issue under these circumstances.

Vehicle: 2019 Kia Sorento (VIN: [XXX] at Incident: 171,800 Description of Incident: On Sunday, August 31, 2025, at approximately 12:30 PM, my 2019 Kia Sorento experienced a sudden and catastrophic engine failure while in motion. I was driving with my two children at approximately 60 mph on Highway 111, a major highway in Palm Springs, CA. Without any warning whatsoever, no dashboard lights, sounds, or symptoms, the engine failed and the vehicle immediately lost all power. The gas pedal became completely unresponsive, and I was left to coast from highway speeds down to a natural stop. My safety and the safety of my children were severely at risk. Being in a vehicle that is unable to accelerate or even maintain speed on a major highway creates an immediate and extreme hazard for being rear-ended by other traffic moving at 60+ mph. We were a vulnerable, slow-moving obstacle with no ability to power ourselves out of a dangerous situation. The vehicle was towed to the Palm Springs Kia dealership in Cathedral City, California, where it was inspected by their service department. A certified Kia technician confirmed the cause of failure was a cracked engine valve, requiring a full engine replacement. I am the original owner of this vehicle and have a complete and documented history of performing all scheduled maintenance. This incident represents a severe safety defect, as a sudden loss of motive power in traffic places the vehicle occupants and surrounding drivers at high risk of a serious collision.

This morning my 2019 Kia Sorento lost power all while driving on a busy highway going 70 miles per hour. When this occured the battery light flashed twice and then the instrument cluster had all warning lights. Then the cluster started flashing and the infotainment center lost power. I lost power steering and brakes. This is not the first time this has happened and I am extremely upset. I drove to the nearest dealership because it was the next exit off of the highway. The engine was running but nothing else was working. The dealership could not get it out of park after I arrived and then it would not start. This same issue occured in 2023 and the dealer had it for over 90 days. They claimed everything was fixed and multiple things were not resolved. My cluster has sparatically flashed since 15k miles and this is ridiculous. Kia will not honor warranty or admit that this is a lemon.

Possible components/systems with issues: Engine, Suspension, Electrical, Emergency Parking Brake and Auto Hold, Back-Up Camera, Parking Collison Warning, et al Been trying to get my vehicle issues resolved. I have not been able to enjoy nor use my vehicle. I've had numerous repeat service appointments. I feel unsafe using the vehicle. Issues have almost caused accidents. It is now at the dealership and I've been in a loaner vehicle almost 3 months. 1. Suspension problems: I had to drive at reduced speeds and avoid highway usage. Poor driveability and rough handling. Felt like tires would pop off. 2. Oil consumption: Poor performance, reduced power and fuel economy. Check engine light came on. Dealership said I had no oil, history codes, and code for injector misfire. They cleared the codes, told me to come back if codes come back. Had me to do oil consumption tests every 1,000 miles which showed low oil levels. I had to restrict usage of my vehicle for the testing. They ultimately said someone did not properly do the testing and there was never an issue with oil consumption. I believe there was an issue. Check engine light keeps coming on. 3. Back-up camera was replaced for recall. New camera had issues causing inverted images, distorted views, and malfunctions with parking and blind spot sensors. Could not use camera. Took back to dealership multiple times, they checked and said they fixed it but it was not. 4. Emergency Parking Brake and Auto Hold Malfunction: Dashboard indicator for Auto hold malfunction and messages for activation/deactivation of emergency brake/Parking. Vehicle would stop abruptly while driving without notice. Almost caused several accidents. Auto hold would not function as designed so vehicle would keep moving when it was activated, however, the vehicle is not supposed to move when it is activated. Had to pull over, turn vehicle off and back on. Sometime it cleared, sometimes it didn't. Dealership could not replicate so had me record

Bought car with 36k miles on it in July 2023. In Jan 2024, engine light came on and we noticed loss of power shifting between gears, had fuel injectors replaced/cleaned. In Feb 2024 at 51k miles, car made knocking noise, pulled over and shut car off, would not restart. Towed to KIA dealer, told the engine was seized and crankshaft snapped. I had regular oil changes every 5,000 miles as recommended by KIA. KIA dealer showed sludge in the bottom of the oil and accused me of adding oil after the engine failed -- false. KIA would not provide any remedy and is charging me $12,000 to replace engine. Seeing other complaints here for the same issue leads me to believe that this is a known issue for KIA on these engines but it has not yet reached critical mass.

We have been experiencing a lost of power. The engine sputters and loses power when accelerating. This has happened on several occasions. Today, 10/11/2021, we were nearly hit four times on interstate 580 in Oakland. We were travelling in the number two lane at sixty miles per hour. I began to accelerate to reach the speed limit when the Sorento began to sputter and lost power to five miles per hour. As we lost power the vehicle behind me nearly rear-ended our vehicle. As we moved to the shoulder we were almost struck two more times. Once on the shoulder I turned the Kia off and back on. I attempted to accelerate on the shoulder and it sputtered and lost powers at twenty miles per hour to five miles per hour. I have done research and its apparent there is a major safety issue with this year. Its unfortunate it take a loss of life (or lives) to have a major recall.
