2018 Kia Sorento 2.4 GDI. In late 2024 a Kia dealer performed an oil-consumption test and confirmed the engine was burning excessive oil. In Feb 2025 the engine long block was replaced. Within about 4,000 miles the vehicle began setting P1326 warnings, misfiring, losing power, and struggling to climb hills. On a highway trip from South Carolina back to Indiana, the vehicle could barely maintain 30–40 mph on grades with the accelerator floored while traffic was moving much faster. The check-engine light returned repeatedly. The vehicle eventually died on an exit ramp and had to be pushed out of traffic and towed. I felt it was unsafe to drive but was repeatedly told by dealers that it was “OK to drive” or that the issue was “bad gas.” After visits to multiple dealers, the current Kia service center finally diagnosed a severely clogged exhaust. They report the manifold catalytic converter and underbody converter have broken down internally and are heavily coated in carbon/oil deposits, and state this likely came from the engine burning oil before and around the time of the rebuild. Exhaust temperatures have been recorded at very high levels, and the engine will only run briefly with an O2 sensor removed to vent exhaust; with the exhaust sealed it will not stay running. The dealer has warned there may now be internal engine damage from prolonged backpressure. The vehicle has been undriveable for many months and the failed converters are being retained and are available for inspection. My concern is that excessive oil consumption on these GDI engines is causing secondary catalytic-converter failure, extreme power loss, stalling risk, and possible fire risk from overheated exhaust components, even after engine replacement.

I was driving and the vehicle shut off. All electric still on lights, radio, dash, etc. No issues or noises indicating that the engine was having faliure. Did not overheat, had oil and gas. Just bought car used 6 months ago with 140k miles. Had it towed to Mechanic and was told the engine was locked. Engine repair is my only option that is going to cost 5-8k. Vehicle has been maintained regularly with only one previous owner and no major repairs ever needed to be done.
On May 1, 2024, I noticed my 2018 Kia Sorento making a knocking sound and smoking heavily from the back exhaust. I turned it off, thinking it might be overheating, and planned to check it the next day. On May 2, 2024, while taking my daughter to school, the vehicle was knocking but no indicator lights were displayed, the main display screen suddenly showed an engine control system issue, and the car spoke and said to take the vehicle to the closest service center I immediately headed to the Kia service center. About 2-3 miles into the drive, the car shut down completely on the interstate. I managed to coast to a stop on the access road but was still partially on the road, so I called for a tow. The police later helped me move the car further off the road because I was a hazard for Morning rush hour traffic. After waiting for three hours, the tow truck took me to the Kia dealership, where the mechanic found that the engine had seized. Kia refused to repair the damage, citing that I hadn't done a KSDS recall. The repairs are estimated to cost over $7000 needing long block replacement from hole in block (KSDS requirements not met). I was not aware of any issues with my car, as I had not been informed about a KSDS recall or any suggestions regarding it. I feel this situation put me in danger, first with the potential fire hazard and then being stranded on the highway and nearly struck in multiple occasions. . I currently have no working vehicle, and Kia is not taking responsibility for these engine issues but my make and model has no listed recall. I am not considered a part of the KSDS recall therefore I also get no claims to the millions awarded to others due to this recall.
My wife was taking my son to school on April 11, 2022 around 7:45am. On the way, and without warning, the engine stopped. She coasted on an exit ramp and stopped at the light. The car's engine wouldn't turn over or even click. A police officer assisted by pushing the car into a gas station parking lot. We had the car towed to the dealer in Fort Worth. After two weeks, they contacted me and said I needed a new engine, intake manifold, and starter because the engine was sized. They said there was no oil in the vehicle. They could not offer an answer as to why.. There had been no warning...no lights had come on the dash...no indication the engine was overheating....no check engine light came on...no check oil light....no limp mode activated. Until that morning, there had been no problems with our vehicle whatsoever. I filed a complaint report with Kia Consumer Affairs. Today, 6 days later, I was told that they would offer no assistance and that all repairs would have to be paid by me. It is available to inspect st the dealer. My wife and child could have been seriously hurt had they stopped in the middle of the interstate by another car running into them. Only the dealer has inspected the vehicle. Had any warning lights come on, we would have had the vehicle serviced. There was never an indication there was a problem.
