Kia Sorento fuel leak problems

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 filing a safety complaint regarding a Kia vehicle I purchased from CarMax Waldorf approximately 3 months ago. The vehicle has developed a strong gasoline/fuel odor that is consistent with a possible fuel leak. This creates a serious safety concern, including the risk of fire or explosion while driving or operating the vehicle. The issue began shortly after purchase and has continued. The vehicle is now unsafe to drive due to the strong fuel smell. When I contacted CarMax about the issue, I was instructed to take the vehicle to a Kia dealership instead of CarMax inspecting or addressing the safety concern themselves. I believe this is improper handling of a potentially dangerous defect in a recently sold vehicle. At this time: * Vehicle emits strong fuel/gas smell * Safety risk increases while driving * Vehicle has been in my possession for only 3 months * Issue appears to be early or pre-existing defect * I was redirected away from CarMax responsibility I am requesting that this safety issue be investigated as a potential fuel system defect and documented appropriately.

The vehicle involved is a 2019 Kia Sorento with approximately 111,000 miles. Over the course of ownership, the vehicle has experienced numerous unresolved mechanical and safety-related issues, including ongoing fuel leak concerns, excessive oil consumption/loss of oil, rough shifting, shift solenoid problems, rattling noises, shaking/vibration while driving, and repeated drivability issues. The primary safety concern at this time is a suspected fuel leak that multiple independent mechanics have identified. I have been told by at least three separate mechanics that the vehicle appears to have a fuel leak. During my most recent oil change at Valvoline, the technician expressed concern about the safety of driving the vehicle in this condition and warned me that driving a vehicle with a fuel leak could be dangerous. I previously brought the vehicle to Kia dealerships multiple times while the extended warranty was active and specifically requested inspection for the suspected fuel leak. On at least three separate visits, I was informed by the dealership that they could not find or confirm a leak. Because the issue was never resolved or properly diagnosed while under warranty, I am now out of warranty coverage and facing potentially dangerous and costly repairs. This issue has placed my safety and the safety of others at risk due to fear of possible fire hazards, stalling, or sudden vehicle failure while driving. Because of these concerns, I have significantly reduced driving the vehicle and currently do not feel safe operating it regularly. This has created substantial hardship because this is my only vehicle for work and daily life. Additional unresolved issues with the vehicle include: - Persistent rough shifting and shifting hesitation - Shift solenoid issues - Ongoing excessive oil consumption/loss of oil with no confirmed source - Constant rattling noises - Excessive vibration/shaking while driving - AC system failure around 60,000 miles - Electrical seat failur

Upper fuel pump module, on top of fuel tank, is leaking fuel from a crack in fuel pump port where fuel hose connects. Fuel can be seen on top of upper fuel pump module and can be seen leaking from fuel pump port, and can be seen on exterior of gas tank. Also fuel odors were present. This could be a fire hazard. The manufacturer issued TSB FUE 064 for this exact issue for vehicles produced from March 31, 2017 through July 24, 2019. Local dealer will not cover the vehicle because it was manufactured in February of 2017. The vehicle has not been inspected by manufacturer, police, of insurance company. There were no warning lamps, messages prior to failure. The symptoms were fuel on top of module, fuel odor, and fuel stain on exterior side of fuel tank

On 3-21-26 I noticed the smell of gasoline after driving the vehicle. Upon inspection a noticeable fuel leak from the top of the fuel tank was evident from underneath the vehicle. Further inspection found fuel leakage at the fuel pump outlet line. After online research it was found that other vehicles of this type have hairline cracks on the fuel pump outlet causing fuel to spray out under pressure. Fuel pump assembly replacement has repaired the problem. No indication other than the smell of gasoline was noted at any time. This is a safety hazard that should be addressed ASAP. Part removed has only been inspected by me. Part is available. If I had not been diligent in addressing this problem the consequences could have been catastrophic. The fuel outlet on a high pressure pump should have never been allowed to be made of plastic. People's lives are at risk!

I am submitting a formal written complaint to supplement my existing the federal safety agency Safety Report ID 11702339 regarding a serious fuel system defect on my 2013 Kia Sorento. My car began experiencing sluggish starting, sputtering during acceleration, stalling at stop signs and traffic lights, and a strong fuel odor. A check engine light subsequently illuminated, and due to safety concerns, the vehicle was towed to a Kia dealership for diagnosis. The dealership confirmed and documented fuel leakage from the high-pressure fuel pressure regulator and fuel contamination in the engine oil. This defect presents a serious safety risks: increased risk of engine fire due to fuel leakage, unexpected loss of power while stopped or in traffic, and increased likelihood of a collision due to engine stalling. This vehicle previously had its engine replaced under a Kia recall in 2020, making this failure particularly concerning. Fuel system failures and post-recall engine-related defects have been the subject of multiple Kia recalls, service campaigns, and the federal safety agency investigations involving engine fires and fuel leaks. Despite the dealership's documented diagnosis and clear safety implications, Kia Consumer Affairs denied recall coverage and refused to assist with repair costs, stating this is not a recall-related issue. The estimated repair cost exceeds $1,700, and the vehicle remains unsafe and undrivable. Given the confirmed fuel leakage, fuel contamination of engine oil, prior recall engine replacement, repeated stalling events, and Kia's refusal to acknowledge responsibility, I respectfully request that the federal safety agency review this case as part of a potential defect trend, particularly involving high-pressure fuel system components on Kia Sorento vehicles with prior recall engine replacements. I am submitting this complaint to ensure this safety issue is formally documented, investigated, and considered for further action to protect consumers. Thank you for your attention to this serious safety matter
