SERVICE BRAKES,ENGINE — Filed 06/18/2026

My wife and I were Driving when I tried to stop and the brakes failed. Within seconds the vehicle caught fire in the engine compartment. I had to slam the transmission into park cause the doors would not open. When my wife tried to escape out the passenger side the flames came into the cabin towards her. I then opened my door and then had to help my wife escape out the driver's side door. Within minutes the car was engulfed in flames. The fire department arrived and it took a while to extinguish. The vehicle is totaled.

I have replaced my rotors and my brakes soon as I got the car I’ve had the car for a month now I was in a major accident. Someone walked in front of my car. My emergency brake system did not work my rotors and my brakes, have been scrubbing ever since I got the car. And I don’t know how to fix the situation. The brakes are still going out and sound very horrible. I can’t keep replacing them because I don’t think they need to be replaced. Is something wrong with the car.

ENGINE — Filed 05/01/2026

2018 Kia Sorento, under 88,000 miles, with Theta II engine defect. KSDS update installed. Oil consumption issues requiring adding at least one liter of oil every 1,000 miles in between regular oil changes/ maintenance. Oil warning lamp does not illuminate at all or only blinks on for a second then stays off, even when oil is less than 1 liter. Noticed slight jerking/hesitation at acceleration for a few days, then experienced shaking and heard vibrations when breaking and idling. Within a few minutes, MIL appeared with audible warning, "Take this vehicle to a Kia dealership." Immediately parked car. Towed to Kia dealership. No record of DTC P1326 found, which would have qualified vehicle for new engine under PI1802 Y/Z Theta II Extended Warranty. Diagnostic found misfiring cylinder and fouled spark plug. Technician in the video stated "oil consumption." Due to absence of P1326 code, service manager suggests we replace fouled plug and return with the vehicle when the same issue happens again. This does not follow Kia's own guidelines in PI1802 Y/Z campaign for a couple of reasons. First, activation of the MIL in conjunction with the audio warning indicates the Knock Sensor P1326 code should have been generated and stored, but the warning system must have malfunctioned. Service dept. did not to inspect the knock sensor harness for damage or oil saturation which could have kept the code from registering. Second, Service dept. did not consider shaking and vibration as "engine noise," which would have required them to perform a BCT or test for connecting rod bearing noise, providing a pathway to request Techline PWA approve replacing the engine under warranty. Kia's Product Improvement Campaign for Theta II engines ought to prevent injury or death resulting from catastrophic engine failure. My vehicle presents clear evidence of engine failure progression at different stages. Rather than navigate the warranty via a Techline, Kia has advised me to continue driving.

My 2018 Kia Sorento has developed excessive oil consumption consistent with the known engine defects affecting Kia’s Theta II engines. The vehicle began consuming oil rapidly without warning, despite regular maintenance. This issue did not appear until after 100,000 miles, which is common for this defect. The sudden loss of oil creates a serious safety hazard, including engine stalling or failure while driving. Kia dealerships have acknowledged the symptoms but stated that because my vehicle is outside the warranty, I must pay for the oil consumption test and would be responsible for the full cost of an engine replacement. Kia has issued multiple Technical Service Bulletins related to excessive oil consumption in these engines, and many owners have experienced the same problem. This is a manufacturer‑related defect that develops over time and poses a safety risk to drivers and passengers.

UNKNOWN OR OTHER,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE — Filed 04/04/2026

I've never had a problem staying awake driving. I don't have this problem in my vehicles or other vehicles. Every time I drove the car. I could not stay awake. I ve driven the car about 5xs. I would fall asleep and not even realize it. Now fell asleep driving the car two nights ago. No warnings went off and I drove over one lane and off into the center medium. No lane change warnings went off. But I truly believe there's something more going on with the car that's making people fall asleep. My neighbor rode with me to the store in it (14 miles ) she was falling asleep. She wasn't one bit tired when we left my house. Once we got out of the car and we're changing the oil on it, we walked over to the store a couple blocks away. We were fine. Got back in the car. Started driving it home and both of us were falling asleep. There was something wrong with this car

Sunroof was working properly, no issues. I parked car with sunroof open and when i restarted car it started closing extremely slow. Technicians have tried resetting but no luck. This is a safety issue that has been repeatitive on KIA Suvs since 2012 or 2014. Techs cannot reset sunroof and last KIA I owned was 2014 had same issue plus drainage hole issues. A panoramic sunroof malfunction can be a safety issue for a few reasons: 1. Emergency situations: In the event of an accident or emergency, it may be necessary to quickly evacuate the vehicle. A stuck panoramic sunroof could prevent passengers from being able to exit through the opening, potentially putting their safety at risk. 2. Ventilation and air circulation: On hot days, being unable to open the sunroof can lead to uncomfortable and potentially dangerous conditions inside the vehicle due to poor ventilation. This can increase the risk of heat exhaustion or dehydration for passengers. 3. Excessive heat build-up: A closed sunroof can also lead to excessive heat build-up inside the vehicle, which can be particularly dangerous for children, elderly individuals, or pets who may be more sensitive to high temperatures. 4. Visibility issues: A sunroof that is stuck closed can also affect visibility for the driver, especially when driving in bright sunlight or in adverse weather conditions such as heavy rain or fog. Overall, a malfunctioning panoramic sunroof can impact the overall safety and comfort of passengers and drivers, highlighting the importance of ensuring that all vehicle components are in proper working condition. KIA refuses to address the issue and needs to take accountability for this ongoing issue that each model has continued to have.

My car for the last 2 years has had multiple malfunctions with misfiring and replacement of head gaskets, pistons and more. Not to mention consistence oil concerns. On two occasions my family and I had to have the vehicle towed home over 200 miles because the car was not driving well. I have a [XXX] ghter who was with us at the time. The only warning lamp that ever triggered was the check engine. In October is when I was informed about a recall that was on my vehicle from KIA the corporation and I was told to have it towed to Kia in [XX [XXX] ey would replace my engine if the rod barring failed; and it did. Kia refused to pay for the engine and reported that I was misinformed. In December of 2025 I went through the Attorney General for mitigation to try and fix the engine- However, Kia reported because the engine manufacturer recall was not updated prior to October 30th or 2020 it was considered failure on the consumers part for not updating their address. However, I have documentation that the vehicle was sign for by myself on December 2nd of 2020. I have the car fax reporting that the car was surrendered by the previous owner on October 28th, 2020. Therefore, I was not the own when this manufacturer warrantee recall was in place or when it expired. So, I do not feel since i did not own the car when this was to be completed, that I should be responsible. Not to mention I am paying on the loan that financed this vehicle for the last 7 months while it has sat at KIA in [XXX] [XXX] ION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ELECTRICAL SYSTEM,EXTERIOR LIGHTING,VISIBILITY/WIPER — Filed 01/09/2026

The vehicle’s ignition system began malfunctioning immediately after a recall-related service (Campaign CS2312 – ignition cylinder protector installation) performed on January 9, 2026. Prior to this service, the vehicle had no ignition or electrical issues. After the repair, the ignition key became difficult to turn, and the vehicle intermittently failed to start. Additionally, multiple electrical components began to fail intermittently, including the infotainment screen shutting off, the air conditioning system stopping, and windshield wipers not operating at times. These failures create a safety concern, as they may affect visibility, driver awareness, and vehicle operability while driving. The issue was reported to the dealership, and their own inspection confirmed that the ignition key cylinder is sticking. The vehicle remains available for inspection, and the condition persists.
