2018 Kia Sorento fuel system problems

Filed Aug 27, 2026 · Fuel system · GA

The High Pressure Fuel Pump failed while driving on highway. I took it to the Kia dealership and they told me of the issue. There were no prior warnings of issues Kia recalled all 2019-2020 kia sorentos with this same issue. This component should not have failed at 63k miles and Kia should extend their warranty to previous models with the same High Pressure Fuel Pump problems under The High-Pressure Fuel Pump Warranty Extension (WTY034).

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.

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.

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.

The Vehicle emits a strong fuel odor: seems to be around the rear of vehicle & front engine compartment of vehicle. Seems the fuel system, both low & high pressure fuel pumps and their pipes channels are leaking to emit a strong fuel odor. Extreme high volatile combustion & fire risk! Remedy: the fuel system including both low & high pressure fuel pumps & their pipes channels need replaced with strong, better engineered components! A newer vehicle like this should not be having fuel system failures.

* High pressure fuel pump quick disconnect fuel line fitting leaking fuel. * Raw fuel leaking poses a risk of fire and danger to the vehicle occupants. Raw fuel leaking in a closed in area as it did in my garage could have lead to an explosion due ignition of the fuel vapors. * My vehicle was repaired by a KIA dealership. The dealership noted that they've seen this issue several times in the past few months including one instance where the fuel line fitting actually fell off. The dealership acknowledged this failure hasn't yet become a recall issue which is why I'm filing a complaint with the NHSTA to establish a record of the issue. * The component was probably discarded by the dealership. The dealership didn't mention sending the part out for inspection or reporting the issue to the manufacturer. Galeana KIA did provide 2 pictures of the fuel leak area. I've attached these to this form. * There were no warning lamps or messages for this type of leak. The vehicle drove as normal. It wasn't until I parked the vehicle in my garage that I noticed a strong smell of raw fuel.

My kia Sorento is involved in an engine recall. When driving on the highway three times now my engine has stalled and car has gone from 65 to 30 mph, almost causing multiple accidents while driving with my [XXX] and [XXX] . The Kia customer service agency said this must occur three times before they will replace my engine. They are not replacing the engine. I fear for my life, my husband life and my children’s lives . I also fear for fellow drivers on the road . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2018 Kia Sorento that I absolutely love. As of late, I have noticed that 1,000 to 1,200 miles after my oil changes- I am getting my engine oil light on, on the dash. Upon checking, again after only 1,200 miles after an oil change- my engine oil was completely gone. The dipstick was almost bone dry. I took my vehicle in to have an oil leak test, because I instantly thought I had a leak due to that being an excessive amount of oil missing. However, there is no leak. It passed the leak test, and there is also no oil in my driveway. Upon talking to the Kia dealership this is apparently a very known, and prominent issue with this vehicle. I am "out of warranty" with Kia- so I am unable to file a claim with them to have this repaired. This is unacceptable for them to know that this is an ongoing issue, and they are not standing behind their products. I have thankfully purchased an extended warranty with an outside agency, that I am filing a claim for. However they will only cover the issue at Kia if the "engine oil consumption test identifies the failure" From what the service man said to me, from Kia- the two "failures" that they have, are either needing to have a combustion chamber cleaning done, or an entire new engine dropped in. Both of which leave me without a vehicle for WEEKS. As a mother with young children, and also a mother that works and has a one vehicle home- this leaves me needing to rent a car for however long that may take. Looking into this further I have seen that Kia Sorentos with the GDI motor (like mine) from NEWER years, have a recall on their engines for a very similar case and very similar situations with them burning excessive oil in their vehicles. I strongly think that the lower year makes and models need to be investigated, as well. I absolutely think that my vehicle needs to be included in this recall as I have gotten and maintained every single oil change, and service needed to my vehicle since I have purchased it in 2020.

Oil leak was diagnosed as bad oil pressure switch that is under extended warranty for certain Kia Sorento models with GDI system, but not my car.

Fuel expired much quicker than should be, and burned on to the dip stick before oil was due to be changed. Then the engine failed while driving, causing my vehicle to lose power on a left turn on a 55 mph road, nearly causing my children and I to be hit by another vehicle. I could not accelerate, but still had power to steer and brake. After having the gas pedal fully extended, I resumed power to 30 mph (this was described as engine knock sensor decreased power). We are hearing that 14 million Kia vehicles are experiencing this. There are 46 cars ahead of mine to be repaired for the failed engine and oil problem at that dealership as of today. They are not offering loaner vehicles.
