Kia Sorento engine failure problems

Severe high-pressure fuel system failure and engine oil fuel dilution creating a fire hazard and engine seizure risk following a corporate engine replacement. On July 15, 2026, my 2016 Kia Sorento (2.4L GDI) received a corporate-covered engine block replacement due to rod bearing failure. On September 30, 2026 (2,332 miles later), the vehicle jerked violently while driving. Inspection revealed the engine oil was heavily diluted with gasoline due to an internal failure of the High-Pressure Fuel Pump (HPFP), creating a fire hazard. The HPFP was replaced out-of-pocket. Kia Corporate Case #26456059 is open regarding this safety issue. A severe safety hazard currently persists. Within 20 days and 176 miles of this fuel pump repair (totaling 2,512 miles on the new block), the vehicle exhibits severe drivability issues and the oil dipstick again smells heavily of gasoline. This fuel dilution compromises oil viscosity, threatening catastrophic engine seizure and creating an active fire hazard. Due to the severity of this fire risk, the Kia Executive Director of Customer Care intervened, ordering an emergency flatbed tow to a different authorized facility. An invoice audit revealed the dealer violated Kia repair protocols, factory TSBs, and federal safety guidelines. Kia’s factory TSB mandates that the high-pressure fuel pipe is a strict, single-use component that must be replaced upon pump removal; however, this part was completely omitted from my invoice, confirming it was dangerously reused. Reusing it introduces a volatile engine-bay fuel leak risk, mirroring the hazardous pattern in the federal safety agency Recall 18V‑907 (Kia Campaign SC172) regarding fuel lines mishandled during engine swaps. Furthermore, the dealer illegally charged retail fees for Service Campaign SC340 materials and withheld all diagnostic trouble codes (DTCs). I request a formal the federal safety agency investigation into unsafe recall compliance and systemic powertrain installation failures originating from the engine replacement.

1. Headlight Failure (Recall Malfunction): Last year, my headlights began intermittently shutting completely off while driving at night, creating an immediate visibility hazard. Kia of Palmdale performed the designated recall repair, but the dangerous defect remains. The headlights still shut off unexpectedly while the vehicle is in motion. 2. Shift Lock Failure: In May 2024, just two months after purchasing the vehicle, the shift lock mechanism failed completely. This intermittently prevented the vehicle from shifting properly out of park, creating an entrapment and stalling hazard. 3. Catastrophic Engine Failure: Last week, the 3.3L V6 engine suffered a sudden, catastrophic mechanical failure while driving. This caused an immediate loss of motive power, putting me and other drivers in severe danger.

The engine failed due to a manufacturing defect that is well known in the company but they aren't calling it a recall, they are calling it an improvement and therefore my car isn't qualifying and isn't being repaired

I bought a used 2020 Kia Sorento LX 2.4L in 2022. It had 15,000 miles on it. AT 50,000 miles I noticed it was consuming oil. I have been changing the oil at 5,000 mile intervals even though the manual calls out to do it every 7,500 miles. I have records of the maintenance for every oil change done on this vehicle. I kept a log and now at 54,740 miles it is consuming 1 quart every 500 miles or so. I took it to the dealer on 10/19/2026 and was told that since I was not the original owner there was no warranty coverage on it. So that nullified the 10 year/100,000 mile warranty. I was told they could do a chamber cleaning for $800.00 and if that failed I would need to replace the engine at an out of pocket cost to me of $9,000.00 to $10,000.00 I have to monitor the oil level constantly to avoid the engine seizing and breaking down in traffic . This auto is used by my spouse to drive my grand kids to and from school. There are no warnings or messages on the oil level so it is driven with uncertainty .

I am the original owner of a 2016 Kia Sorento and have lived at my original registration address since purchasing the vehicle. The engine suddenly and catastrophically failed/seized due to internal rod bearing failure. The local Kia dealership is denying the recall engine replacement because the KSDS (Knock Sensor Detection System) software update was not performed. However, Kia America failed to mail me a statutory recall notice to my verified address. The dealership is weaponizing Kia's own notification failure to deny coverage for an acknowledged safety defect."

The contact rented a 2015 Kia Sorento. The contact stated that the headlights and tail lights intermittently failed to illuminate or shorted out, and the check engine warning light illuminated. While driving at approximately 35 MPH, the vehicle suddenly seized in the middle of an intersection, and the contact was unable to move the gear shifter out of gear. The local police department arrived on the scene and assisted the contact by disassembling components around the gear shifter in order to shift the transmission into neutral (N). The vehicle was then towed back to the rental business. The failure mileage was approximately 207,000. The VIN was not available.

On October 3, 2026, at approximately 12:30 p.m., my 2019 Kia Sorento, with fewer than 100,000 miles, experienced an unexpected engine failure while I was driving on the highway in the Chicago, Illinois, area. Component or System Failure: The vehicle's engine failed unexpectedly while the vehicle was being operated on the highway. The exact internal component responsible for the failure is currently UNKNOWN. However, the vehicle has since been inspected by an authorized Kia dealership, and I have been informed that the engine repair was approved. The availability of the failed engine or its components for further inspection is currently UNKNOWN. Safety Risks: What makes this incident particularly alarming is that my daughter was in the vehicle with me when the engine failed. We were traveling on the highway, surrounded by vehicles moving at high speeds, when we experienced this unexpected mechanical failure. This situation placed both my daughter and me in a potentially life-threatening situation. The sudden engine failure could have resulted in a serious collision, catastrophic injuries, or even the loss of both of our lives. As a mother, it is deeply disturbing to know that my daughter and I were exposed to such a dangerous situation while simply traveling in our vehicle. We could have been involved in a devastating accident through no apparent fault of our own. My concern extends beyond the inconvenience and financial burden of having my vehicle break down. This was a serious safety incident that endangered not only my life but also the life of my daughter and potentially other motorists on the highway. Dealer Confirmation: Following the incident, I contacted Kia to arrange an inspection and repair. Unfortunately, the earliest available service appointment was October 8, 2026, five days after the engine failure. An authorized Kia dealership subsequently inspected the vehicle and approved the engine repair. I am requesting the complete diagnostic finding
