Oil consumption on other Sorento years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2020, 2021, 2022, 2023, 2024, 2025.
What this problem usually is
Two different complaints land here. The more common one is an engine that uses oil: owners add a quart between changes, get a low-oil warning, or are told by the dealer that the rate is normal. The other is the opposite, where the oil level climbs and the oil smells of gasoline. Both deserve a proper test, and both are easier to argue with records in hand.
What got replaced
Owners who name the part that was replaced mention the piston rings (6 reports) and the engine (4 reports).

Is this a known problem?
The manufacturer has sent NHTSA 4 service bulletins or notices for the 2018 Kia Sorento that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

“Around 90,000 miles, the engine started leaking oil regularly, took it in for warranty. After repairs for gasket, then started burning oil and running of oil every week or two weeks, and I have to constantly refill oil. Took it again and Dealer told me I am out of warranty, then I called KIA USA and reported problems. They told me that they will get back to me and I am still waiting.”

Should you keep driving it?
This page can't tell you that. 0 of 26 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
