Quick Verdict: The 2022 Kia Sorento PHEV at a Glance
The 2022 Kia Sorento Plug-In Hybrid occupies a narrow but compelling niche: a three-row SUV that can handle most daily commutes on electricity alone, then switch to a conventional hybrid powertrain for longer trips. With an EPA-rated 32 miles of electric-only range and 79 MPGe combined, it lets drivers who lack reliable home charging access—or who regularly tow, road-trip, or face extreme cold—experience meaningful EV benefits without range anxiety. Now available primarily on the used market, the 2022 model year represents a mature package with known reliability data and a battery warranty that largely transfers to second owners.

HEV vs. PHEV: What's the Difference on the Sorento?
Kia offered the 2022 Sorento in three powertrain variants: a conventional gas model, a standard hybrid (HEV), and a plug-in hybrid (PHEV). The distinction matters enormously for fuel costs and daily driving.
| Attribute | Sorento HEV (Standard Hybrid) | Sorento PHEV (Plug-In Hybrid) |
|---|---|---|
| Needs to be plugged in? | No — charges via regenerative braking and engine | Yes — plug in to access electric-only range |
| Battery Size | 1.49 kWh | 13.8 kWh |
| Electric-Only Range | ~1 mile at low speed | 32 miles (EPA) |
| Combined MPG / MPGe | 37 MPG combined | 79 MPGe (EV) / 34 MPG (hybrid) |
| Combined Horsepower | 227 hp | 261 hp |
| Drivetrain | AWD | AWD |
| Federal Tax Credit (original) | Not eligible | Eligible — up to $7,500 (see rules below) |
The conventional HEV is simpler and cheaper upfront: you never plug in, and it returns a strong 37 MPG combined. But it can't drive on electricity alone at meaningful distances or speeds. The PHEV trades a slightly lower hybrid-mode MPG (34 vs. 37) for the ability to complete most daily commutes—school runs, grocery trips, office drives—without burning a drop of gasoline, provided you charge at home overnight.
Fuel Economy: EPA Numbers and Real-World MPG
According to fueleconomy.gov, the 2022 Kia Sorento PHEV achieves:
| Mode | City | Highway | Combined |
|---|---|---|---|
| Electric (MPGe) | 79 MPGe | 79 MPGe | 79 MPGe |
| Hybrid (MPG) | 36 MPG | 33 MPG | 34 MPG |
Real-World MPG vs. EPA Sticker
Hybrid and PHEV owners frequently report exceeding EPA city estimates because regenerative braking recovers more energy in stop-and-go traffic. In mixed suburban driving with regular plug-in charging, many Sorento PHEV owners see effective fuel consumption well below what the 34 MPG hybrid-mode rating suggests—simply because the engine never starts on shorter trips.
On sustained highway driving above 70 mph, expect hybrid-mode efficiency to drop to approximately 30–32 MPG. Aerodynamic drag and the added weight of the 13.8 kWh battery (the PHEV is roughly 300 lbs heavier than the HEV) work against it at speed. In cold weather below 30°F, electric-only range typically drops 20–30% due to cabin heating demands and reduced battery efficiency, bringing the usable EV range closer to 22–26 miles.
Total Combined Range
With a full charge and a full 14.5-gallon fuel tank, the Sorento PHEV delivers approximately 440–460 miles of total range (32 miles electric + roughly 420 miles in hybrid mode). That's competitive with the conventional gas Sorento and eliminates range anxiety entirely for road trips.
Electric-Only Range, Charging, and Battery Specs
The 2022 Sorento PHEV's 13.8 kWh lithium-ion polymer battery delivers an EPA-rated 32 miles of electric-only driving. In practice, drivers who accelerate gently and stay below 65 mph can stretch this to 34–36 miles in mild weather. Aggressive acceleration, highway speeds, or cold temperatures compress it to 24–28 miles.
Charging Speed and Connectors
The Sorento PHEV uses a standard J1772 connector for Level 1 and Level 2 AC charging. It does not support DC fast charging—this is typical for PHEVs, whose smaller batteries don't justify the added cost and weight of DC hardware.
| Charging Level | Power | Time (0–100%) |
|---|---|---|
| Level 1 (120V household outlet) | ~1.4 kW | ~10–11 hours |
| Level 2 (240V, 32A home charger) | ~7.2 kW (vehicle-limited to 3.3 kW onboard charger) | ~3 hours 25 minutes |
A critical detail: the Sorento PHEV's onboard charger is rated at 3.3 kW. Even if you connect it to a 7.2 kW or 11.5 kW Level 2 station, the vehicle will only draw 3.3 kW. This means a full charge takes about 3.5 hours regardless of the station's maximum output. For most owners charging overnight at home, this is perfectly adequate—the battery is full before morning. But it also means you can't "top up" quickly at a public charger during a midday stop.
On Level 1 (a standard 120V outlet), expect roughly 3–4 miles of range added per hour. Owners with short commutes (under 20 miles round-trip) can often keep the battery topped off with Level 1 alone, avoiding the $500–$1,500 cost of a Level 2 home installation.
Powertrain: 261 Horsepower with Turbo and Electric Assist
The Sorento PHEV pairs a 1.6-liter turbocharged four-cylinder gasoline engine (178 hp, 195 lb-ft) with a 66.9 kW electric motor (roughly 90 hp) integrated into the transmission housing. Combined system output is 261 hp and 258 lb-ft of torque, routed through a 6-speed automatic to all four wheels.
The result is a 0–60 mph time of approximately 8.4 seconds—brisk for a three-row SUV and noticeably quicker than the 227 hp HEV variant. The electric motor fills in the low-RPM torque gap that small turbo engines typically exhibit, making the Sorento PHEV feel responsive from a stop. At highway speeds, the turbo engine and electric motor work in concert, and the transition between EV and hybrid modes is generally seamless.
All-wheel drive is standard on the PHEV (and on the HEV), using an electronically controlled coupling to send torque rearward when needed. This is not a dedicated rear-motor AWD system like some EVs use; instead, a driveshaft connects the front-mounted powertrain to the rear axle.
Battery Warranty, Reliability, and Replacement Cost
Kia's Hybrid/PHEV Battery Warranty
Coverage: 10 years or 100,000 miles (whichever comes first)
Capacity threshold: Kia covers the battery if it falls below approximately 70% of original capacity
Transferability: For the 2022 model year, Kia's 10-year/100,000-mile powertrain and battery warranty is transferable to subsequent owners, though coverage may reduce to 5 years/60,000 miles depending on the original purchase date and state. Verify with a Kia dealer using the VIN.
Long-Term Reliability
Kia's 1.6L turbo engine and 6-speed automatic have been in the Hyundai/Kia family since approximately 2018, and the PHEV variant of this powertrain debuted in the Niro and Sorento. As of 2026, four-year reliability data on the 2022 Sorento PHEV shows no systemic battery failure pattern. The lithium-ion polymer cells have proven durable in normal use, with most owners reporting minimal range degradation after 50,000–70,000 miles.
The conventional hybrid components—regenerative braking, motor-generator, power electronics—carry the same warranty and have a strong track record across Hyundai/Kia's lineup. The Sorento as a platform received mixed reliability scores from Consumer Reports in its first year, primarily related to infotainment glitches and minor electrical issues rather than powertrain concerns.
Battery Replacement Cost
Should the PHEV battery require replacement outside of warranty, expect a cost between $4,000 and $6,500 including parts and labor at a Kia dealership. Third-party hybrid battery refurbishers may offer rebuilt packs for $2,500–$4,000. Given the 10-year/100,000-mile warranty, most original and second owners will never face this expense. The 13.8 kWh pack is significantly cheaper to replace than a full EV battery (which can run $10,000–$20,000+), precisely because it's smaller.

Decision Framework
Choose the Sorento PHEV if:
- Your daily round-trip commute is under 30 miles and you can charge at home overnight
- You need three rows and AWD but aren't ready to commit to a full EV
- You take road trips of 200+ miles regularly and don't want to plan around charging stops
- You live in a cold climate where EV range loss is a concern
Choose the Sorento HEV (standard hybrid) instead if:
- You cannot charge at home (apartment, street parking, no garage)
- Your commute exceeds 35 miles one-way (the battery depletes early, and you're running on the less-efficient 34 MPG hybrid mode)
- You want the lowest purchase price and simplest ownership experience
Choose a full EV (e.g., Kia EV6, Hyundai Ioniq 5) instead if:
- You can install a Level 2 charger at home and rarely drive more than 250 miles in a single day
- You want zero gasoline costs, zero oil changes, and DC fast charging for road trips
- You only need two rows of seating
Frequently Asked Questions
How many MPG does the 2022 Kia Sorento Plug-In Hybrid get?
In hybrid mode (after the battery is depleted), the Sorento PHEV returns an EPA-rated 36 city / 33 highway / 34 combined MPG. When operating on electric power, it achieves 79 MPGe combined. Real-world city MPG in hybrid mode often exceeds the EPA estimate thanks to regenerative braking, while highway driving above 70 mph typically yields 30–32 MPG.
How far can the 2022 Sorento PHEV go on electric only?
The EPA rates it at 32 miles of electric-only range. In mild weather with gentle driving, expect 34–36 miles. In cold weather (below 30°F) or at sustained highway speeds, expect 22–28 miles. The gasoline engine seamlessly starts when the battery is depleted or when you demand hard acceleration.
Does the 2022 Sorento PHEV qualify for a tax credit?
When purchased new, it was eligible for up to $7,500 under the §30D federal credit, subject to income caps, MSRP limits, and battery-sourcing requirements. On the used market, the §25E credit may offer up to $4,000 if the sale price is $25,000 or less and the buyer meets income thresholds. Check current rules at irs.gov or consult a tax professional before relying on credit eligibility.
Is the 2022 Sorento PHEV reliable, and what does a battery replacement cost?
The powertrain has shown no systemic reliability issues through four years of owner data. Kia's 10-year/100,000-mile battery warranty covers capacity loss below approximately 70%. Out-of-warranty battery replacement runs $4,000–$6,500 at a dealer, or $2,500–$4,000 through a third-party refurbisher. Given the warranty length, most owners will never face this cost.
Can the Sorento PHEV DC fast charge?
No. The 2022 Sorento PHEV supports only Level 1 (120V) and Level 2 (240V) AC charging via a J1772 connector. Its onboard charger is limited to 3.3 kW, so a full charge takes about 3 hours 25 minutes on Level 2. This is standard for PHEVs—the smaller battery doesn't require or benefit from DC fast-charging infrastructure.
How does the Sorento PHEV compare to the Sorento HEV?
The PHEV offers 32 miles of electric-only range, 261 hp, and AWD for a higher purchase price. The HEV delivers 37 MPG combined without needing to plug in, at a lower cost and slightly lighter weight. If you can charge at home and your daily driving is under 30 miles, the PHEV will use significantly less gasoline. If you can't charge at home, the HEV is the more practical and economical choice.
Is the third row usable in the Sorento PHEV?
The third row fits small children or occasional short-trip passengers. Adults will find legroom tight (approximately 29.6 inches of third-row legroom). Cargo space behind the third row is limited to about 12.6 cubic feet. If you regularly need three full-size rows, a minivan or larger SUV is a better fit. The PHEV battery does slightly reduce under-floor cargo storage compared to the gas model.
