At $557 a month over five years, the 2021 Kia Sorento costs more to own than most buyers expect when they see its used sticker price. That $33,432 total from our ownership calculator includes depreciation, fuel, insurance, maintenance, repairs, and registration. It does not include surprises. And with certain trims of this Sorento, there are surprises.
The verdict: A well-chosen 2021 Sorento in the $22,000 to $26,000 range is a reasonable buy. It is a third-generation model with genuine interior improvements over its predecessors, decent reliability on the base engine, and a useful three-row layout. But the 2.5T turbocharged four-cylinder has an oil consumption problem that has burned enough owners to make it a real concern. Buy the right trim, pay the right price, and this is a solid used family SUV. Buy the wrong one and you are managing an engine problem from day one. Check Kelley Blue Book and Edmunds for current private-party and dealer pricing before you negotiate anything.
The 2021 Sorento comes with three powertrain options: a 2.5-liter naturally aspirated four-cylinder, a 2.5-liter turbocharged four-cylinder (the 2.5T), and a 1.6-liter turbocharged hybrid. The naturally aspirated 2.5 is the one to buy. It is not exciting, but it is not eating oil either.
The 2.5T is the problem. Multiple owners have reported consuming a quart of oil every 1,000 to 2,000 miles, sometimes more. Kia has acknowledged oil consumption concerns on this engine in other models sharing the same platform. If you are not checking your oil every few weeks on a car this new, you may find yourself with low oil and accelerated engine wear. On a vehicle that already has 40,000 or 50,000 miles on it, that is not a theoretical risk.
The hybrid is actually a reasonable choice if you can find one priced fairly. Its 1.6T engine is paired with a belt-driven integrated starter-generator system. It is newer technology with less long-term data, but early reliability signals are not alarming.
Stick to the LX, S, or EX trims with the naturally aspirated engine. Avoid the SX and SX Prestige with the 2.5T unless you have documentation of oil consumption monitoring and the seller can show clean service records.
The 2021 Sorento has had recalls, and you need to know about them before you buy. Check the NHTSA recall database for the specific VIN you are considering. Notable issues include a recall related to the panoramic sunroof glass potentially detaching, and software concerns with the forward collision avoidance system. Neither is catastrophic, but both require confirmed repair before purchase. Ask the seller for recall completion documentation, or run the VIN yourself on the NHTSA site.
The 2022 Sorento is a safer pick on the recall front, with fewer open campaigns at this point. If your budget stretches to a low-mileage 2022, it may be worth the extra cost.
RepairPal rates the Sorento above average for reliability overall, but that rating is heavily influenced by older generations with the 2.4-liter engine. The 2021 is early in its reliability data curve.
What owners actually report on the 2021 is a different picture depending on trim. On the naturally aspirated LX and EX, complaints are minor: occasional infotainment glitches, a lane-keeping assist system that can be aggressive, and some wind noise from the door seals at highway speeds. These are annoyances, not repair bills.
On the 2.5T, the oil consumption issue shows up as early as 20,000 miles. Owners have also reported turbo lag hesitation and, in some cases, check engine lights tied to the turbocharged system. A turbo replacement on this engine runs $1,200 to $2,000 at an independent shop.
The electrical systems on 2021 Sorentos have generated a moderate number of complaints, mostly around the infotainment system freezing or losing Bluetooth pairing. These rarely require expensive fixes, but they are persistent.
Our five-year total of $33,432 assumes a typical used buyer driving 12,000 miles per year. But your actual repair and maintenance costs shift significantly depending on where the odometer sits when you buy.
Under 50,000 miles: You are mostly in scheduled maintenance territory. Expect oil changes, tire rotations, cabin and engine air filters, and maybe a brake fluid flush. Budget around $600 to $800 per year for maintenance. Repairs should be minimal, maybe $200 to $400 annually if anything shows up. The warranty situation helps here: Kia's powertrain warranty runs 10 years or 100,000 miles for the original owner, but transfers to 5 years or 60,000 miles for subsequent owners. Confirm exactly where the warranty stands before you sign.
50,000 to 100,000 miles: This is where you start spending real money. Spark plugs, brake pads, and potentially rotors will be due. If the car has the 2.5T and oil consumption has been occurring, you may be looking at early carbon buildup on intake valves, which requires a walnut blasting service costing $400 to $600. Budget $1,000 to $1,500 per year for maintenance and repairs combined.
Over 100,000 miles: Budget $1,500 to $2,500 per year. Water pump, accessory belts, and suspension components come due. On the hybrid, the battery pack is a long-term question mark. The naturally aspirated 2.5 tends to hold up well past 100k with clean oil changes, but neglected examples can develop valve train noise and timing chain stretch.
These are specific to the 2021 Sorento. Do not skip them.
Check the oil level and condition. Pull the dipstick before you drive it. Low oil on a five-year-old car with under 80,000 miles tells you everything you need to know about how it was maintained, and potentially about 2.5T oil consumption.
Check for oil consumption history on the 2.5T. Ask for service records showing how often oil was added between changes. If the seller does not have records, walk.
Test every ADAS feature. The 2021 Sorento's forward collision warning, lane keep assist, and blind spot monitoring have all generated complaints. Make sure they activate and function correctly on a test drive.
Check the panoramic sunroof for cracks or delamination. The recall involves the glass potentially separating. Confirm the recall was completed and inspect the sunroof frame seal carefully.
Listen for transmission shudder on the 8-speed automatic. At low speeds, some owners have reported a shudder or hesitation. This is most noticeable during slow acceleration in a parking lot. A software update has addressed some cases, but not all.
Inspect the third row and its folding mechanism. The third-row seats in the Sorento are functional but tight. The folding mechanism can bind if the car has been used hard. Test it manually.
Check the infotainment system for software version. Older software versions have more freezing issues. A dealer can update it, but confirm it has been done or factor in a service visit.
Look for rust around the rear hatch and lower door seams. Sorentos in northern climates have shown some early surface rust in these spots by year four or five. It is cosmetic now but worth negotiating on.
The EPA rates the 2021 Sorento at 26 mpg combined for the naturally aspirated front-wheel-drive version. See the full breakdown at fueleconomy.gov. At 12,000 miles per year and $3.50 per gallon, that works out to roughly $1,615 per year in fuel. Our five-year fuel figure of $10,668 accounts for the AWD variants and the turbocharged trim, which drops to 24 mpg combined and costs noticeably more to fill.
The hybrid version earns 39 mpg combined. At the same 12,000 miles and $3.50 per gallon, that drops annual fuel cost to around $1,077. Over five years, that gap adds up to real money. If you drive mostly city miles, the hybrid case gets stronger.
2021 Hyundai Santa Fe: Built on the same platform as the Sorento, priced similarly, and available without a troublesome turbocharged engine option in the base trims; it is worth cross-shopping if you want something a little smaller and do not need a third row.
2021 Mazda CX-9: In the same price range used, the CX-9 has a stronger reliability record, a better interior, and a turbo four that does not have documented oil consumption issues at this scale.
Buy a 2021 Kia Sorento LX or EX with the naturally aspirated 2.5-liter engine, under 70,000 miles, priced at $22,000 or below, and you have a decent deal. Our five-year cost of $33,432 is manageable for what you get: real three-row space, modern safety features, and acceptable reliability. Go above $26,000 for any trim, and the depreciation math stops working in your favor. Buy the 2.5T without confirmed oil consumption records, and you are gambling with an engine that has a documented weakness. The car is not overpriced at the right number, but the right number matters more here than it does with most vehicles in this class.
