Used Kia Sorento 4th Gen (2021-2025): Buyer's Guide

Car and Driver tested a 2022 Kia Sorento for 40,000 miles. Their conclusion: it wasn't very reliable. The culprit was the 2.5-liter turbocharged engine paired to an 8-speed wet dual-clutch transmission. A circuit board component inside the DCT's electric oil pump detaches due to insufficient soldering. When it fails, the vehicle throws a "stop safely immediately" warning, drives for another 20 to 30 seconds, then loses all drive power.

Kia recalled 65,612 units. A Kia-Forums thread tracking the failures drew over 150,000 views and 400 replies. Owners reported waiting two to four months at dealerships for replacement transmissions.

But the 4th-gen Sorento also comes with three other powertrain options. One of them has none of these problems. The 2021 through 2025 generation is a legitimately capable vehicle if you know which engine to buy, which years to target, and what to verify before signing.

This guide covers exactly that.

This Generation at a Glance

The 4th-gen Sorento (MQ4 platform) launched for 2021 as a clean-sheet redesign. Kia dropped the optional V6 from the 3rd-gen lineup and replaced the beam rear axle with independent multi-link suspension. The result is a more composed ride and a more modern feature set, with a mandatory trade-off: every powertrain now uses a four-cylinder engine.

A 10.25-inch touchscreen display became standard across all trims for 2022. The X-Line off-road variant and Plug-In Hybrid joined at the same time. No significant structural platform changes occurred through the 2025 model year.

Key mid-cycle note: 2022 and later models are the ones to target for most buyers. The 2021 had the highest recall and complaint burden of the generation.

Powertrain and Trim Breakdown

2.5L MPI (Naturally Aspirated): The Safe Pick

The base 2.5-liter MPI engine uses multi-port injection and pairs with a conventional 8-speed automatic transmission. Not the DCT. That distinction is the most important thing to understand about this generation.

Output is 191 horsepower and 181 lb-ft of torque. It's adequate for everyday family use, but noticeable when the third row is occupied and highway merging is required. The engine belongs to Kia's Smartstream G2.5 MPI family (G4KN/G4KM) and uses port injection, meaning fuel washes over the intake valves. Carbon buildup is not a concern on this engine the way it is on pure direct-injection motors.

The 2.5L MPI is available on the L, LX, and S trims. It sidesteps the DCT recall entirely. Kia-Forums discussions about the base powertrain are almost entirely absent of mechanical complaints. Owners report routine maintenance without surprises.

FWD is standard on this engine. AWD is optional on LX and S trims at a modest upcharge.

What to watch for: Not much. Check for deferred maintenance (cabin filter, spark plugs at 60k-75k), and listen for any accessory belt noise. Budget $300 to $500 for scheduled maintenance catch-up on higher-mileage examples.

Verdict: Most reliable combination in this generation. The trade-off is 90 fewer horsepower and lower towing capacity.

2.5L T-GDI (Turbo): High Risk on Early Builds

This is the engine that gave the 4th gen its reliability reputation. On paper, it's excellent: 281 horsepower, 311 lb-ft, and AWD standard. In practice, the 8-speed wet dual-clutch transmission it's paired with produced a documented manufacturing defect that reached tens of thousands of owners.

Kia's investigation confirmed the root cause: a component on the electric oil pump's circuit board detaches due to insufficient soldering at the supplier. The pump fails to supply oil to the transmission clutches. The vehicle enters a fail-safe mode, displays "stop safely immediately," and loses all drive power within 20 to 30 seconds.

NHTSA Recall 22V760000 covers 65,612 units built between October 26, 2020 and August 25, 2022. That means all 2021 turbo models and most 2022 turbo models fall within the recall window.

The Kia-Forums thread "Transmission failed: DCT failures / manufactured date / SA502A ECU update" accumulated 150,000 views and over 400 replies. Owners reported units failing before and after recall work, multiple replacement transmissions on the same vehicle, and multi-month dealer waits during peak parts shortages. Car and Driver's 40,000-mile long-term test of a 2022 Sorento turbo ended with DCT failure.

The recall involves either an oil pump replacement or a full transmission replacement, depending on the condition of the unit. Some early recall completions involved only the SA502A ECU software update, which addresses fail-safe behavior but not the root cause. If you are buying a recalled-and-repaired unit, ask for the service record and confirm whether the transmission was physically replaced, not just software-updated.

Post-August 2022 production units fall outside the recall window. Forum discussions from 2023 onward show significantly fewer DCT complaints for the turbo model. The manufacturing defect appears to have been corrected at the supplier level.

The Theta III 2.5T engine itself uses dual injection (both direct and port) which reduces the carbon buildup risk common to older Theta II pure-GDI engines. No systemic engine failure patterns have been documented on the Theta III through typical used-car mileages.

One additional 2021-specific issue: Recall 21V519000 covers a fuel system leak at the high-pressure fuel pump connection, posing a fire risk. Confirm this recall is completed on any 2021 turbo model before purchasing.

What to watch for: Cold-start transmission behavior at low speeds. A healthy DCT should engage smoothly even in parking lot crawl. Hesitation, shuddering, or gear hunting at under 5 mph indicates a compromised DCT. Walk away from any turbo model that hasn't had verifiable recall work.

Verdict: Acceptable buy on verified post-recall or post-August 2022 production. High caution on 2021 and early 2022 builds without documented transmission replacement.

1.6L T-GDI Hybrid: The Best All-Around Choice

The hybrid uses a 1.6-liter turbocharged engine integrated with an electric motor and generator, paired to a 6-speed automatic transmission. It is architecturally separate from the 2.5T DCT combination. The hybrid powertrain does not share the oil pump circuit board issue.

Combined system output is 227 horsepower. In FWD form the hybrid achieves 37 mpg combined. AWD brings it to 34-35 mpg. That is better fuel economy than any comparable 3-row family SUV in this price range.

Owner feedback on the hybrid is substantially more positive than feedback on the 2.5T gas model. The most consistently reported complaint is a false "Refill Inverter Coolant" dashboard warning. Across Kia-Forums and Reddit discussions, owners report the message appearing when coolant is at the correct level. Kia has addressed this through TSBs. In most cases it's a sensor calibration issue, not a coolant failure.

Throttle hesitation when transitioning from EV-only to hybrid mode is another documented behavior. When electric torque hands off to the combustion engine at low speeds, some owners feel a brief pause. This is inherent to how the hybrid system manages the transition, not a defect.

Air conditioning performance in EV-only mode draws more battery, which some owners report as slightly reduced cooling on very hot days. Normal behavior for the system.

What to watch for: Verify inverter coolant level at purchase. Note any active hybrid system warning codes. At mileages over 100,000 miles, ask about hybrid battery condition and any past replacement history.

Verdict: Best combination of reliability and fuel economy in this generation. Strong buy across 2021-2024, with the usual caveat to verify HVAC fire recall completion.

1.6L T-GDI PHEV: The Right Tool for the Right Buyer

The plug-in hybrid joined the lineup for 2022 on the SX Prestige PHEV trim. It uses the same 1.6T hybrid base with a larger 13.8 kWh battery and a second electric motor on the rear axle for AWD. EPA-rated all-electric range is approximately 34 miles. Combined system output is 261 horsepower.

The PHEV is the most capable and most expensive powertrain in the generation. Owner reviews from Edmunds across 2022-2024 are mostly positive. The value case is strong for buyers who charge daily and run most trips under 34 miles.

Two documented issues affect PHEV models specifically. First, NHTSA recalled 2022-2023 PHEV models with factory-installed tow hitches: moisture and debris can enter the harness connector, creating an electrical short with fire risk. Confirm this recall is completed before purchase. Second, isolated Edmunds owner reports describe hybrid battery management system warnings appearing within the first year of ownership, with some requiring battery replacement under warranty. This is not a documented systemic pattern but is worth checking in service records.

What to watch for: Confirm tow hitch harness recall status. Test that the vehicle charges to full and displays a realistic EV range estimate. Check service records for any past hybrid system warning codes.

Verdict: Excellent for buyers who can use the EV range regularly. Higher complexity means higher repair costs if something fails. Stick to CPO or warranted examples when possible.

Trim-Specific Notes

The 4th-gen trim structure creates a clear fork at the EX level: L, LX, and S get the 2.5L NA with conventional automatic; EX and above get the 2.5T turbo with DCT, or the option to spec a hybrid powertrain.

S: The value pick for reliability-focused buyers. Gets the 2.5L NA, 8-speed conventional AT, and a meaningful feature set. The 2022 update added the 10.25-inch touchscreen, forward collision avoidance, lane-keeping assist, and blind-spot warning as standard. If you want to avoid the DCT risk and don't need the extra 90 horsepower, the S trim is the right answer.

EX (gas): First trim to get the 2.5T and 8-speed DCT. Adds heated front seats, power driver's seat, and dual-zone climate control. On a 2023 or later EX, the DCT risk is substantially lower. On a 2021-2022 EX, verify recall work before purchase.

EX Hybrid and SX Hybrid: These are the sweet spot for buyers who want features beyond the base S trim without the DCT risk. The hybrid powertrain brings 37 mpg combined and the same reliability profile as the standard hybrid. Worth the price premium over the equivalent gas EX or SX.

SX and SX Prestige (gas): Higher trims with the 2.5T. Adds leather, panoramic sunroof, Bose audio, and full active safety suite. Same production-year DCT caveats apply. Well-equipped and genuinely pleasant to drive once the transmission concern is resolved.

SX Prestige PHEV: Top trim with plug-in capability. Best feature content in the lineup. AWD standard. For the right buyer who charges regularly, it offers the lowest effective fuel cost of anything in this segment. Confirm tow hitch harness recall if the vehicle has a hitch.

X-Line: Off-road styled variant with raised ride height, X-Line badging, and AWD. Uses the 2.5T gas engine. DCT concerns apply by production year.

Note on third-row practicality: the third row is standard on all trims. It fits children comfortably and adults for short trips. Legroom in the third row is tighter than in larger 3-row SUVs. If third-row adult use is a primary requirement, note this before purchase.

Which Model Years to Target Within This Generation

2021: The highest-risk year in the generation. Three concurrent fire-related recalls affect the turbo model: DCT oil pump (22V760000), fuel system leak at the HPFP connection (21V519000), and HVAC blower wiring (25V649000). If buying a 2021, restrict the search to the 2.5L NA S or LX trim. Verify all applicable recalls are completed.

2022: High complaint count (166) and four recalls make this a cautious year. The DCT recall covers turbo models produced through August 2022. The turbo oil pipe fire recall (22V202000) applied to a narrow production window in March 2022 and covered approximately 26 units. For 2022 turbo models: confirm recall 22V760000 is completed, and ask specifically whether the transmission was replaced.

2023: First full model year outside the original DCT recall window. Complaints dropped from 166 to 90. The remaining recalls are comparatively minor: camera mounting clips and airbag warning labels. HVAC wiring fire recall (25V649000) still applies and should be confirmed completed. Best value year for buyers who want the turbo.

2024: The sweet spot. Two recalls, both software updates. Only 29 complaints on record. No mechanical drivetrain concerns. Strong buy for turbo, hybrid, and PHEV models. The 2024 Sorento represents the generation at its most refined.

2025: The connecting rod bolt recall (25V548000) is a serious manufacturing defect: improperly torqued rod bolts can cause complete loss of drive power and require sub-engine assembly replacement. The 2025 is still a serviceable vehicle once this recall is completed, but verify it before purchase. The headlight software error (25V006000) and HVAC wiring recall also apply.

Best overall year: 2024 across all powertrains. Best value for turbo buyers: 2023-2024. Best budget entry: 2023 S trim.

Pre-Purchase Inspection Checklist

Run the VIN through a recall lookup before the test drive. Check for outstanding campaigns 22V760000, 25V649000, and any year-specific recalls from the table above.

For all 2.5T turbo models (2021-2022 production):

• Request service records showing recall 22V760000 completion. Confirm whether the transmission was replaced or only software-updated. An ECU update alone (the SA502A calibration) addresses fail-safe behavior but not the oil pump hardware defect.
• Drive the vehicle cold if possible. Navigate low-speed city traffic, stop-and-go. The DCT should engage smoothly at under 5 mph. Hesitation, shuddering, or gear hunting at parking lot speeds warrants investigation.
• On the highway, do a full-throttle acceleration run. A healthy DCT shifts cleanly and without slip. Any flare or hesitation under load is a red flag.
• Ask the seller when the DCT fluid was last serviced. The 8-speed wet DCT uses Kia SK-5 fluid. Not every independent shop will stock it; factor in potential dealer-only service.

For hybrid models:

• Note the inverter coolant reservoir level before starting the vehicle. If the "Refill Inverter Coolant" message appears during the drive, confirm the reservoir is actually low or dismiss it as the known false-positive issue. Either way, note it in your negotiation.
• Test the AC on a warm day in EV-only mode. Reduced cooling is normal behavior; no cooling output at all is not.
• Check service records for any hybrid system warning codes or battery replacements.

For PHEV models:

• Confirm tow hitch harness recall is completed on 2022-2023 models.
• Verify the vehicle charges to full capacity and that the displayed EV range estimate is consistent with the EPA figure.
• Ask about any past "Hybrid System" or "Battery Management System" warning events.

For all years:

• Confirm HVAC blower wiring recall (25V649000) is completed. This affects 2021-2023 and 2025 models. Ask for a dated repair order.
• Inspect the windshield carefully. Spontaneous cracking has been reported across multiple owners without a clear impact cause. If a crack is present, negotiate a replacement or walk.
• Press the brakes firmly at 30-40 mph. Any pulsation or vibration indicates rotor wear. Budget $300 to $600 for a full brake service.
• Test the third-row fold mechanism both directions. Should move without sticking. Some early units show stiffness from disuse.

Running Costs

RepairPal data puts average unscheduled repair costs for the Kia Sorento at $533 per year, below the compact SUV class average of $573. Owners bring their Sorentos in for unscheduled work 0.3 times per year on average.

The 2.5T DCT requires Kia SK-5 DCT-specific fluid. Change interval is 40,000 to 60,000 miles. Not all independent shops stock this fluid; budget for dealer-only DCT service if you go the turbo route.

Hybrid brake pads last longer than on gas models because regenerative braking handles most deceleration at normal speeds. Still budget for brake fluid flushes every two years regardless of pad condition. Fluid degrades with heat even when friction wear is minimal.

Five-year total maintenance cost for the Sorento runs approximately $2,736, well below class average.

FAQ

Is the 4th-gen Kia Sorento reliable? It depends on the powertrain. The 2.5L NA engine with 8-speed conventional automatic has no documented systemic failures. The 2.5T turbo's 8-speed wet DCT had a confirmed manufacturing defect affecting 65,612 units built through August 2022. On post-recall or post-August 2022 production, the turbo has a substantially better record. The hybrid and PHEV powertrains use a different transmission architecture and do not share the DCT issue.

Which year Kia Sorento 4th gen should I avoid? Avoid 2021 turbo models with unverified recall work, and exercise caution with 2022 turbo models unless recall 22V760000 was completed with a confirmed transmission replacement. The 2021 also carries a separate HPFP fuel leak fire recall. For the 2025, verify the connecting rod bolt recall is completed before purchase.

Is the Kia Sorento Hybrid reliable? The 1.6T hybrid uses a 6-speed automatic, not the DCT. It does not share the oil pump failure issue. The most common complaint is a false "Refill Inverter Coolant" dashboard warning that appears when coolant is at the correct level. Throttle hesitation during EV-to-hybrid transitions is normal system behavior, not a defect.

Does the 4th-gen Kia Sorento have a third row? Yes. A third row is standard on all 4th-gen Sorento trims. Legroom is comfortable for children and tight for adults on longer trips. If you need three rows of adult seating regularly, evaluate this during the test drive.

How many miles will a 4th-gen Kia Sorento last? Properly maintained NA and hybrid models should reach 150,000 to 200,000 miles without major mechanical failure. Turbo models with verified DCT recall completion are expected to perform similarly. Pre-recall turbo units with unresolved DCT issues carry significant longevity risk beyond 100,000 miles.

Bottom Line

The S trim with the 2.5L NA engine is the low-risk pick: reliable, well-equipped, and free from the DCT saga. The EX Hybrid or SX Hybrid is the best overall choice for buyers who want features and fuel economy with a clean reliability record. If you want the turbo gas engine, stick to 2023-2024 production and verify any outstanding recalls before handing over money.
