    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)

    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.

    In April, 2025, my vehicle's engine power was significantly reduced while on the highway. I could not keep pace with traffic. My mechanic said there were recalls for the turbo engine but my car was not included. I paid forbthe part and repair. Less than a year later and the car began burning a lot of oil very fast. I add oil weekly. The car has again been losing power and there is still no recall for my car's engine. There is burning and smoke coming from the engine because of an engine oil leak Jiffy Lube detected yesterday, Mar h 11, 2026. The problem began at around 65k miles and now has 88k miles.

    I have less than 100,000 miles on my 2018 Kia sorento. When I reached probably 50,000 miles this car went DOWN HILL. I feel like I’ve replaced everything on this car. Now every oil change was saying no oil on the dip stick, so I take it to the Kia dealership. They tell me that I need an ENTIRE engine. My car is less than 100,000 miles. I saw something that said if it was under that threshold, it could be covered but they said they couldn’t find anything. This car has been failing me. I still owe HALF of the car, what it’s not even worth on carfax anymore. AND the engine cost is exactly 50% of what I owe on this car. I don’t know what to do, but never buy a Kia again. This is a hazard for everyone around me the gas it is putting into the air. I don’t know what else to do. I even paid them to do an oil change and the oil light lit up as SOON as I left the parking lot. There are no leaks whatsoever. I even had someone from the Kia engine settlement verify my VIN # and told me that it was eligible and she told me that everything would be taken care of at the dealership without charge. She then told me to wait for the dealership to call and let me know because I was on hold while they were talking. But right after I received a call asking how I was going to pay for it because they could not find anyway to cover it. I don’t know how to ask for a second opinion. Kia is never available to speak with or try to resolve the issue. This has just been a nightmare.

    While on the road driving at 35 MPH, the vehicle started to "bog" and losing power and/or acceleration. Had to immediately drive off the road as there were several vehicles behind. As soon as driving off the road, the vehicle died down and would not start again. The check engine light came on. After several minutes the vehicle started again and drove to a secure area to call the tow truck. If the vehicle died down while in traffic, it would have caused an accident involving several vehicles. If it happened on the freeway, it would have caused a "major accident". The vehicle was towed to the vehicle dealership. It was determined by the vehicle dealership that the "high pressure fuel pump" was faulty and had to be replaced. It took four (4) months for the replacement part to arrive. Another similar dealer said that there were "55 other vehicle owners" waiting on the same part nationwide. It must be an "inherent problem" with the high pressure fuel pump. After replacing the high pressure fuel pump, the vehicle was operating normally.

    On January 30, 2026, I was driving with my daughter from Kansas City to Platte City when the vehicle experienced a sudden and catastrophic mechanical failure. As we approached our exit, the engine unexpectedly revved and the vehicle rapidly decelerated to approximately 30 mph. When I attempted to accelerate, the vehicle was unable to properly gain speed. Upon reaching the top of a hill at an intersection, the engine completely shut off and the vehicle became disabled in the roadway. The vehicle was towed and inspected by two independent repair facilities. Both repair facilities confirmed catastrophic internal engine failure. A bore scope inspection identified a broken valve in cylinder 4, along with severe internal engine damage. The first repair facility estimated the cost of engine replacement at $9,600. The second repair facility confirmed the same diagnosis and recommended full replacement of the long block assembly. Copies of the inspection reports and repair estimates are attached. Due to the extent of the internal damage and the high cost of repair, the vehicle is considered mechanically inoperable and beyond reasonable repair. The cost of repair is substantial and exceeds our ability to proceed with repairs. At the time of the mechanical failure, approximately two years remained on the finance agreement, with an outstanding loan balance of approximately $12,000. As a result of this catastrophic mechanical failure, the vehicle is unusable, and a financial deficiency remains on the loan. Although the engine carried a warranty, we were informed that the specific failure was caused by internal component failure and material shedding, which is not covered under the warranty terms. Supporting documentation, including diagnostic findings, repair estimates, and photographs of the failed engine components, are attached. Due to the sudden and catastrophic mechanical failure, the vehicle has sustained a total mechanical loss and is no longer operable.
