2016 Kia Sorento: engine failure

Filed Nov 4, 2026 · Engine, Fuel system · RI

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.

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."

Vehicle equipped with 3.3L V6 Lambda II engine, covered under active Kia Warranty Extension Campaigns WTY035/WTY039 for engine block head bolt/gasket failure.In July, the vehicle experienced a cooling system issue and was brought to authorized dealer Westgate Kia. Despite explicit campaign guidelines mandating a coolant pressure test and chemical combustion block test for cooling complaints on this engine, the dealership failed to follow the TSB protocol. They attributed the issue solely to an external hose, recommended unrelated peripheral repairs, and released the vehicle without performing the required campaign diagnostics.A few months later, the unchecked progressive manufacturing defect resulted in catastrophic engine failure. The vehicle exhibited intermittent overheating, blew heavy white smoke from the tailpipe (indicating a massive head gasket breach/coolant entering combustion chambers), and ultimately suffered a total loss of cylinder compression, requiring it to be towed back to Westgate Kia.The dealership is currently trying to evade the 15-year/180,000-mile WTY035/WTY039 campaign coverage. The service department is refusing to follow the mandated diagnostic flowchart to check for stripped engine block head bolts, instead claiming the failure is due to a "melted radiator." They are attempting to blame the consequences of the extreme engine overheating on peripheral parts to avoid performing the required engine sub-assembly replacement under the federal campaign.

Upon a catastrophic engine failure Tasca Kia replaced engine under Theta II settlement. I picked up my kia on 9/12. Engine is not running properly. It’s jerking and there is loud mechanical knocking. I don’t feel safe driving. I’ve contacted Kia corporate beginning 9/16 who contacted Tasca to arrange for tow and loaner. They said Tasca service mgr would contact soon to set up. They never did. I called corporate again later that day and after they called Tasca they were told service mgr went home for the day. As of this date Tasca Kia has not contacted me. I again called Kia corporate 9/17 asking to please escalate and allow me to use another service dept. The only other service location with loaner is a half hour away and I cannot afford another tow or another rental. I am stranded with a car that is not safe due to installation failure or another defective engine. No one from Kia will help in a reasonable time frame. I’m now told it can take up to 48 BUSINESS HOURS for any assistance. In the meantime I’m being forced to decide on whether to risk driving an unsafe vehicle to the service dept or to continue waiting for Kia to contact me.

I am filing this complaint regarding a 2016 Kia Sorento, VIN [XXX]. The vehicle suddenly broke down while my [XXX] daughter was driving in [XXX] and was taken to Sooner Kia in [XXX]. The dealership diagnosed the engine as seized and stated that it failed because there was no oil, requiring engine replacement. We dispute that conclusion. Within approximately five minutes of the breakdown, my daughter checked the oil at her father’s direction, and the level appeared normal. A mobile mechanic later inspected the vehicle and also reported that the oil level was normal and appeared clean. Sooner Kia now claims the engine was “bone dry” and that lack of oil caused the seizure. We have requested documentation showing how much oil was found, whether any oil was drained, what testing was performed, what internal damage was identified, and what evidence proves that oil starvation caused the failure. We have not received documentation establishing the cause. This is concerning because the federal safety agency previously investigated loss of motive power involving 2016–2017 Kia Sorento vehicles with 3.3L Lambda II engines under PE23-019. Kia later created extended warranty campaign WTY035 for certain related failures. Please document this complaint and review whether this engine failure may be related to those known issues. We are being asked to authorize an expensive engine replacement without evidence supporting the dealership’s conclusion.

On or about XXX, my KIA Sorento LX FWD Auto 2.4-liter engine with an approximate mileage of 36,000, began having drivability problems, none of which occurred before that date. On XXX the vehicle was serviced at Ourisman Chantilly Kia (VA051) for a Voluntary Emissions Service Campaign (SC340) THETA II 2.4L GDI ECM S/W Upgrade. Records reflect that it was a Theta II Emissions Logic Improvement 250A21R1 0.3 M/H. This was a voluntary campaign from Kia America, Inc., [XXX]. Failure to have this performed, as cited from the Kia Corporate Headquarters, could nullify warranty/warranties. What ensued was a vehicle that stalled, seized, hesitated, and/or jolted at low speeds that had the potential to cause severe injury or accident. Uncontrolled rough accelerating and seizing is a serious complaint, and the causation can be linked to the dealership performing the voluntary recall where the vehicle was purchased on March 15, 2015, in [XXX]. Further, this vehicle has a full and complete record of all repairs and symptoms, which includes, and is not limited to, maintenance, Service Campaign, Service Action, Recall, and Product Improvement. This vehicle, included in a class of vehicles with a history of potential engine failures, has a Lifetime Engine Warranty extension coverage included in PI1802 Y/Z Engine R&R Warranty Bulletin 2020-26 and PI1802W/X Warranty Bulletin 2018-10. Therefore, when the records were reviewed for the initial Voluntary Emission Service Campaign recall code SC234 completed in 2022, along with my former the federal safety agency Complaint Number XXX submitted electronically, an apparent history of obfuscation relating to material safety concerns emerges. KIA America, Inc. sold this Kia as a five-star safety rated vehicle. It now makes me feel uneasy with its defective drivability.

While I was driving, my 3.3 V6 engine on my 2016 Kia Sorento seized up with no warning. There is no visible oil on the dip stick, although I have changed my oil routinely. There has never been visible oil outside of the engine or on the ground. I never had any warning light come on. I believe the engine burns an extreme amount of oil, which is putting people in a dangerous situation and financial hardship.

Car completely stalled while on the freeway with no warning, no engine lights, nothing….luckily we were going downhill and were able to pull over to the side safely. Still owe 6k to the finance company but mechanic claimed I needed a new waterpump…after being changed and charged the car still wouldn’t turn on despite the new waterpump….and a bunch of new obd codes showed up & now I need a new engine. After a lot of research I’ve learned this car is notoriously known for many recalls and overall complains…..I wish I had done research before buying it, now I’m in debt for a car I can’t even drive
