The 2021 Kia Seltos is a small SUV with more room than you might expect. It has a tall roof, comfortable back seats, and enough cargo space for groceries, luggage, and weekend trips. It also offers all-wheel drive on most versions, which is useful if you regularly deal with rain or snow.
Kia introduced the Seltos to the United States for the 2021 model year, placing it between the smaller Soul and the larger Sportage. Buyers could choose between an economical 2.0-liter engine and a quicker 1.6-liter turbocharged engine.
Today, the Seltos is an interesting used SUV for drivers who want practicality without the cost or size of a larger vehicle. But there are a few important things to check before buying one, including engine recalls and transmission behavior.
Here’s how the 2021 Seltos holds up, which version makes the most sense, and what to look for on a test drive.
2021 Kia Seltos Overview
| Specification | Details |
|---|---|
| Vehicle type | Subcompact SUV |
| Seating capacity | 5 passengers |

| Transmission | Intelligent Variable Transmission or 7-speed dual-clutch |
| Drivetrain | Front-wheel drive or all-wheel drive |
| Fuel economy | 27–31 MPG combined |
| Cargo space | 26.6 cubic feet behind rear seats |
| Maximum cargo space | 62.8 cubic feet |
| Ground clearance | 7.3 inches |
| Fuel tank capacity | 13.2 gallons |
| Original starting MSRP | $21,990 |
| Available trims | LX, S, S Turbo, EX, SX Turbo |
The Seltos was an all-new model in the US for 2021, so there wasn’t an older American version to compare it with.
Its main selling point was simple. It offered many of the useful features people wanted in an SUV without requiring them to buy something much larger.
Exterior Design and Dimensions
The Seltos looks tougher than many small crossovers. Its wide grille, squared-off shape, black body cladding, and available two-tone roof give it a more rugged appearance.
The headlights sit high on the front end, while the short overhangs help make the vehicle look compact and well-proportioned.
The design is practical, too. Large side windows help with visibility, and the upright body creates more usable space inside.
How Big Is the 2021 Kia Seltos?
| Dimension | Measurement |
|---|---|
| Length | 172 inches |
| Width without mirrors | 70.9 inches |
| Height without roof rails | 63.6 inches |
| Height with roof rails | 64.2 inches |
| Wheelbase | 103.5 inches |
| Ground clearance | 7.3 inches |
At 172 inches long, the Seltos is easy to manage in crowded parking lots and smaller garages.
Its 7.3 inches of ground clearance gives it more room underneath than a typical sedan, which can help on uneven roads and steep driveways.
However, the Seltos isn’t built for serious off-road driving. Its ground clearance and available AWD are better suited to everyday conditions, gravel roads, and light adventures.
Exterior Colors
Kia offered several colors, including Neptune Blue, Mars Orange, Starbright Yellow, Cherry Black, Snow White Pearl, and Dark Ocean Blue.
Some versions also came with contrasting roof colors.
Color availability depends on the trim and factory configuration, so not every combination will be found on the used market.
Engine Options and Performance
Kia offered two engines for the 2021 Seltos. The one you choose makes a noticeable difference in how the SUV drives.
2.0-Liter Four-Cylinder Engine
The standard engine produces 146 horsepower and 132 lb-ft of torque.
It comes with Kia’s Intelligent Variable Transmission, often called an IVT. This transmission works similarly to a continuously variable transmission and is designed to keep the engine operating efficiently.
The 2.0-liter engine is available in the LX, S, and EX trims.
For city driving, commuting, and relaxed highway trips, the engine provides enough power for normal use.
Its biggest weakness is acceleration. Passing at highway speeds or climbing a steep hill with passengers aboard can require more patience than in the turbocharged model.
The engine may also become louder when you press the accelerator hard.
Still, drivers who care more about everyday fuel economy than quick acceleration may find this version perfectly suitable.
1.6-Liter Turbocharged Engine
The available turbo engine produces 175 horsepower and 195 lb-ft of torque.
It comes with a seven-speed dual-clutch automatic transmission and standard all-wheel drive.
You can find this combination in the S 1.6T and SX trims.
The turbo engine provides stronger acceleration, especially when merging onto highways or passing slower traffic.
Its extra torque makes the Seltos feel more responsive, particularly when several people are riding along.
However, the dual-clutch transmission behaves differently from a traditional automatic. It may feel less smooth when moving slowly through traffic or creeping forward in a parking lot.
That doesn’t automatically mean something is wrong, but strong shuddering, slipping, warning lights, or unusually harsh engagement should be investigated.
Which Engine Is Better?
| Feature | 2.0L Engine | 1.6L Turbo Engine |
|---|---|---|
| Horsepower | 146 hp | 175 hp |
| Torque | 132 lb-ft | 195 lb-ft |
| Transmission | IVT | 7-speed dual-clutch |
| Available drivetrain | FWD or AWD | AWD |
| Combined MPG | 29–31 | 27 |
| Driving character | Relaxed and economical | Quicker and more responsive |
The 2.0-liter engine makes more sense if you want a simple daily commuter and better fuel economy.
The turbo engine is more enjoyable if you regularly drive on highways or prefer stronger acceleration.
For either option, the maintenance history and mechanical condition should matter more than the horsepower number when buying used.
2021 Kia Seltos MPG and Fuel Economy
Fuel economy is one of the Seltos’ stronger qualities.
The most efficient version is the S with the 2.0-liter engine and front-wheel drive. It earns an EPA-estimated 31 MPG combined.
Adding all-wheel drive reduces the combined rating slightly, while the turbo engine uses more fuel.
Official EPA Fuel Economy
| Engine and Drivetrain | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|
| 2.0L FWD | 29 | 34 | 31 |
| 2.0L AWD | 27 | 31 | 29 |
| 1.6L Turbo AWD | 25 | 30 | 27 |
These are EPA estimates. Your mileage can vary with driving speed, weather, traffic, tire condition, and how much weight the SUV carries.
How Much Does It Cost to Drive?
Let’s say you drive 12,000 miles per year and pay an average of $3.50 per gallon for gasoline.
Your estimated annual fuel costs would be:
- 2.0L FWD at 31 MPG: approximately $1,355.
- 2.0L AWD at 29 MPG: approximately $1,448.
- 1.6L Turbo AWD at 27 MPG: approximately $1,556.
Under these assumptions, the difference between the most efficient version and the turbo model is about $201 per year.
That isn’t a huge amount, but it adds up during long-term ownership.
All three versions use regular unleaded gasoline, so premium fuel isn’t required.
Driving Range
The Seltos has a 13.2-gallon gas tank.
Based on its combined MPG ratings, the theoretical range is approximately 409 miles for the FWD version, 383 miles for the 2.0L AWD, and 356 miles for the turbo AWD.
These are calculated estimates, not guaranteed distances between fuel stops.
Actual range will be lower or higher depending on driving conditions, and you shouldn’t plan to use every gallon in the tank.
2021 Kia Seltos Interior and Comfort
The interior is one of the most convincing reasons to consider the Seltos.
It has a clean dashboard layout, controls that are easy to understand, and an upright seating position that gives the driver a good view of the road.
The cabin doesn’t feel as cramped as the exterior size might suggest.
There are hard plastics in several areas, particularly on lower trims, but the overall layout is practical.
Front Seats
The front seats provide good headroom and enough adjustment for many drivers.
Higher trims offer more comfort features, including a power-adjustable driver’s seat, heated front seats, and upgraded upholstery.
The EX and SX have automatic climate control, which is more convenient than manually adjusting the fan and temperature throughout a trip.
For long commutes, seat comfort is worth checking in person. A short trip around the dealership won’t always reveal whether the driving position works for you.
Rear Passenger Space
The rear seat has 38 inches of legroom, which is generous for a subcompact SUV.
There is enough space for two adults to sit comfortably on many trips, although fitting three adults across the back will be tighter.
The rear seats also recline, allowing passengers to adjust their seating position.
Families with young children will appreciate the rear-door access and available passenger space. However, parents should test their particular child seats before buying, especially if they need to install more than two.
Cargo Space and Storage
Despite its compact exterior, the Seltos offers a useful amount of room for luggage and everyday gear.
With the rear seats upright, there are 26.6 cubic feet of cargo space.
Fold the rear seats down, and the available cargo area increases to 62.8 cubic feet.
The rear seatbacks have a 60/40 split, so you can fold one section while keeping another passenger seat available.
A dual-level cargo floor also helps with storage. You can lower it to create more vertical space or raise it for a flatter loading surface when the seats are folded.
This makes the Seltos suitable for shopping trips, small furniture, camping equipment, and weekend luggage.
However, it only seats five people. Families that regularly need a third row should consider a larger vehicle. For example, the 2025 Toyota Sienna offers seating for up to eight passengers, although it’s a much larger minivan.
Technology and Infotainment
The Seltos came with a strong selection of technology for its price when new.
The LX, S, and EX trims have an 8-inch touchscreen with Apple CarPlay and Android Auto support.
The SX includes a larger 10.25-inch touchscreen with navigation.
Depending on the trim, additional features include:
- Bluetooth connectivity.
- USB charging ports.
- Wireless phone charging.
- Keyless entry and push-button start.
- Heated front seats.
- Automatic climate control.
- Bose premium audio.
- Interior sound mood lighting.
The Bose audio system and sound-reactive lighting are among the distinctive features of the SX.
For a used vehicle, don’t assume that every Seltos has the same equipment. Confirm the exact trim and test the infotainment system, phone connection, cameras, and charging ports before buying.
2021 Kia Seltos Trim Levels and Original Prices
The Seltos was available in five main trims with six engine and drivetrain configurations.
Here are the original US starting MSRPs.
| Trim and Configuration | Original MSRP |
|---|---|
| LX 2.0L AWD | $21,990 |
| S 2.0L FWD | $21,990 |
| S 2.0L AWD | $23,590 |
| EX 2.0L AWD | $25,390 |
| S 1.6T AWD | $25,590 |
| SX 1.6T AWD | $27,990 |
These are original manufacturer prices, excluding destination charges, optional equipment, taxes, and fees. They are not today’s used-car values.
Kia Seltos LX
The LX is the base model, but it includes all-wheel drive as standard equipment.
It uses the 146-horsepower 2.0-liter engine and comes with basic comfort and connectivity features.
The LX is worth considering if you want AWD without paying for extra luxury equipment.
One thing to remember is that the LX does not have the same advanced driver-assistance equipment as higher trims.
Kia Seltos S
The S offers a sportier appearance and additional features.
It was sold with the 2.0-liter engine in either FWD or AWD form, as well as the optional 1.6-liter turbo engine with AWD.
Features include upgraded interior trim and additional safety technology compared with the base LX.
The 2.0-liter FWD model is the fuel-economy leader.
Kia Seltos EX
The EX adds comfort without requiring the turbo engine.
It comes with the 2.0-liter engine, standard AWD, heated front seats, a power-adjustable driver’s seat, and automatic climate control.
It also includes a sunroof and upgraded interior materials.
For someone looking for a comfortable used SUV, the EX is a good trim to investigate.
Kia Seltos S Turbo
The S Turbo combines the stronger 1.6-liter engine with the seven-speed dual-clutch transmission and AWD.
It’s suited to drivers who want extra performance without moving to the top trim.
Check the transmission carefully during a test drive, particularly in slow traffic.
Kia Seltos SX Turbo
The SX was the most expensive and best-equipped Seltos for 2021.
It includes the turbo engine, AWD, a 10.25-inch navigation display, Bose premium audio, LED headlights, and additional driver-assistance technology.
The SX makes sense if you want the strongest engine and the fullest equipment list.
However, a well-maintained EX may be a smarter used purchase than an SX with poor service history.
Does the 2021 Kia Seltos Have AWD?
Yes. All-wheel drive is one of the Seltos’ most useful features.
The LX, EX, S Turbo, and SX came with AWD as standard. The 2.0-liter S could be purchased with either front-wheel drive or AWD.
The AWD system automatically distributes power to help improve traction when conditions require it.
It also includes a lock mode designed for lower-speed situations where additional traction is needed.
Is It Good in Snow?
An AWD Seltos can be a reasonable choice for drivers who regularly encounter snowy roads.
The system can help the vehicle accelerate on slippery surfaces and improve traction when climbing a snow-covered hill.
However, AWD doesn’t shorten braking distances on ice.
Good tires, careful driving, and appropriate winter equipment are still essential.
For drivers in warmer parts of the United States who rarely face snow, the FWD Seltos may be sufficient and offers better fuel economy.
Safety Ratings and Driver Assistance
The 2021 Seltos received an overall four-star rating from the National Highway Traffic Safety Administration.
The Insurance Institute for Highway Safety also gave it a 2021 Top Safety Pick award, but there is an important qualification.
The award applies only to vehicles built after August 2020 with specific headlights and optional front crash-prevention equipment.
According to the IIHS safety ratings, the Seltos earned Good results in several major crashworthiness tests.
However, some headlight configurations received a Poor rating. The exact trim and production date therefore matter.
Driver-Assistance Features
Depending on equipment, the Seltos can include:
- Forward Collision-Avoidance Assist.
- Lane Keeping Assist.
- Blind-Spot Collision Warning or Assist.
- Rear Cross-Traffic Collision Warning or Assist.
- Driver Attention Warning.
- Smart Cruise Control.
- Highway Driving Assist.
Not all these features are standard, and some are limited to higher trims.
If a particular feature is important to you, verify that it is fitted to the vehicle rather than relying on the model name alone.
2021 Kia Seltos Reliability and Common Problems
The Seltos offers good everyday practicality, but reliability deserves careful attention when buying a 2021 example.
It was the first US model year, and certain vehicles have been included in engine-related recalls.
That doesn’t mean every Seltos will have engine trouble. It does mean buyers should verify the recall status and service history before handing over any money.
Engine Oil Ring Recalls
Two separate safety recall campaigns have included certain 2021 Seltos vehicles equipped with the 2.0-liter engine.
Recall 21V259000, announced in April 2021
This recall involved piston oil rings that may not have been heat-treated correctly.
The problem could cause engine damage, stalling, and, in some circumstances, a fire.
Kia’s remedy included engine inspection, replacement when necessary, and a piston-ring noise detection software update.
Recall 25V099000, announced in February 2025
This later recall affected certain 2021–2023 Seltos and Soul vehicles with the 2.0-liter engine.
It also involved incorrectly manufactured piston oil rings that could lead to engine damage, loss of power, or fire.
Kia’s remedy included inspection, possible engine replacement, and updated detection software.
These are separate recalls. A repair recorded under one campaign should not automatically be treated as proof that every other applicable campaign has been completed.
You can check an individual vehicle using the official NHTSA VIN recall lookup.
If an oil-pressure warning appears, the engine makes unusual noises, or the vehicle loses power, stop in a safe place and follow Kia’s recall safety instructions. Do not continue driving a vehicle showing symptoms of serious engine damage.
Transmission Behavior
The Seltos uses two different automatic transmissions.
The IVT paired with the 2.0-liter engine can feel different from a traditional stepped automatic, particularly during strong acceleration.
The turbo model’s dual-clutch transmission may feel less smooth while creeping through traffic or parking.
A different driving feel is not necessarily a defect. However, delayed engagement, severe jerking, slipping, warning lights, or repeated loss of power deserve a professional inspection.
During a test drive, pay attention to how the transmission behaves both when cold and after the vehicle has warmed up.
Other Things Worth Checking
As with any used SUV, look for uneven tire wear, suspension noises, brake vibration, fluid leaks, and malfunctioning electronic equipment.
Also inspect the paint, body panels, and underbody for accident damage or corrosion.
A vehicle with complete maintenance records and no unresolved safety problems is generally a better starting point than one whose history is unknown.
Kia Seltos Warranty Coverage
Kia originally provided the following coverage for the 2021 Seltos:
| Coverage | Original Warranty |
|---|---|
| Basic limited warranty | 5 years or 60,000 miles |
| Powertrain limited warranty | 10 years or 100,000 miles |
| Anti-perforation warranty | 5 years or 100,000 miles |
| Roadside assistance | 5 years or 60,000 miles |
Coverage ends when either the time or mileage limit is reached, and exclusions apply.
There is an important difference for used buyers.
The full 10-year/100,000-mile powertrain coverage generally applies to the original purchaser and qualifying Kia Certified Pre-Owned buyers. A normal used-vehicle purchase does not automatically transfer the full original powertrain warranty.
Before buying, ask a Kia dealer to check the VIN, original in-service date, ownership history, and remaining coverage.
Don’t assume a vehicle is under warranty simply because it has fewer than 100,000 miles.
How Much Does a Used 2021 Kia Seltos Cost?
The 2021 Seltos originally started at $21,990, but used-car prices depend on much more than the trim.
In nationwide used listings reviewed in October 2026, many examples were advertised in roughly the $12,000 to $20,000 range, although individual vehicles can fall outside that range.
That is an illustrative market snapshot, not a fixed value for every Seltos.
Mileage, accident history, mechanical condition, location, equipment, and dealer fees can all affect the price.
A lower-mileage SX may cost more than an older, higher-mileage LX. But a higher asking price doesn’t always mean a better vehicle.
When comparing listings, look at the total cost, including any dealer charges. Also budget for a pre-purchase inspection, registration, insurance, tires, and maintenance.
What to Check Before Buying a Used Seltos
The most useful part of shopping for a used 2021 Seltos is checking the actual vehicle rather than relying only on its specifications.
Here’s a practical inspection checklist.
1. Check the VIN for Recalls
Ask for the full 17-character VIN and run it through the NHTSA recall search.
Pay particular attention to the applicable engine recalls. Ask for dealer records showing which repairs or inspections were completed.
Remember that the NHTSA VIN search primarily shows unrepaired recalls. For proof of completed campaign work, request documentation from Kia.
2. Review the Maintenance History
Look for regular oil changes and other services performed according to Kia’s schedule.
Missing records don’t automatically mean a vehicle was neglected, but they make its condition harder to judge.
If an engine was replaced, ask for the repair paperwork and mileage at the time.
3. Test Both City and Highway Driving
Drive the SUV in traffic, through turns, and at highway speeds when safe.
Make sure acceleration is consistent and the transmission responds normally.
Try parking, reversing, and moving forward from a complete stop.
4. Listen for Unusual Sounds
Pay attention to knocking, rattling, suspension clunks, and other unfamiliar noises.
Noisy operation by itself doesn’t prove a particular defect, but unexplained sounds should be evaluated.
5. Inspect Tires and Brakes
Uneven tire wear can point to alignment or suspension problems.
Check the brake pedal for unusual vibration, and ask when the brakes and tires were last replaced.
On AWD models, check that the tires are properly matched and in acceptable condition.
6. Test the Features You Are Paying For
Confirm that the air conditioning, heated seats, infotainment display, rearview camera, keyless entry, and safety systems work correctly.
A vehicle may be advertised with optional equipment that it doesn’t actually have.
7. Get an Independent Inspection
A qualified mechanic should inspect the engine, transmission, suspension, brakes, underbody, and visible accident repairs before you commit.
This is especially important for a first-model-year vehicle with documented engine recalls.
A clean-looking interior and short test drive are not enough to establish mechanical condition.
