2021 Kia soul- perfect car for anyone!
I really love how smooth the Kia soul drives. For a smaller class car, it is very spacious. The backseat has lots of room as well! The trunk is a very nice size. The backup camera is extremely helpful when backing into a parking spot or out of one. I love my Kia soul!

Reliable. 100k mile bumper to bumper warranty. 35 mpg. Ample amount of space.
I wanted a Kia soul because my mom's soul has 300k miles on it and has never needed any work other than maintenance fluids and breaks. They're very reliable and have the option for a bumper to bumper 100k warranty, which was highly appealing to me. I get 35 mpg, and there is tons of space in the car. I am 6ft tall so it's hard for me to find a decent compact car that my head doesn't rub the ceiling. I actually had to scoot the seat up. 10/10 recommend.

Soul personality and performance.
I have only owned the 2021 Kia soul for a little over 2 weeks but I am very impressed so far. The vehicle offers all the bells and whistles of much more expensive vehicles in a cool looking and great handling car. This car definitely looks different than most of the cookie cutter vehicles on the road and the soul has a personality of its own.

The dogs and I love our turbo Kia.
My kisa is my third Kia soul. I have three big five. 11 year old and I am a property manager. My Kia is roomy enough for a St Bernard 2 labradoodles groceries work documents an 11 year old and me! The gas mileage is crazy good. The amenities are similar to my friend’s new BMW and the turbo makes it so much fun to drive. The weather is getting cooler so I open the sunroof turn to the music and let the dogs hang out the window! We all love our Kia!

Peppy little car and so fun to drive.
Just purchased this car a couple of weeks ago. Surprisingly peppy. For a small car it has a lot of room inside. Traded in my jeep compass so the gas mileage is way better. The people I have had in the car so far have all said they liked it and that it was very comfortable for them.

My vehicle is a great car. Everyone who needs a good commute car.
I have not had any problems with my car, it is great on gas and really is just overall a great commute car. The gas is great. The size is a little on the small side if you have a baby but that is okay! It is safe and is great for long travels or even just going to work. It has under storage for your tools and whatever else you need.

I am extremely happy with my 2021 Kia soul, they offer amazing deals and warranty.I am so happy I decided to go with the soul it has everything I need and has great gas mileage.

Great small car with a big personality.
It is really great just seems to have wind noise inside the cabin coming from the right passenger window. It drives super smooth and has really good quality interior. It is a lot bigger than you'd think from such a small car. The only other slight downfall is with the lx version you have to connect your phone via USB cable to get the navigation.

What Do Critics Say About the Kia Soul?

  • Consumer Reports says the 2021 Kia Soul is small on the outside but feels roomy on the inside, with good owner satisfaction scores as it ages.
  • Edmunds rates the Kia Soul at 3.9/5, enjoying the responsive steering, but doesn’t like the slow transmission on the turbocharged models.
  • Kelley Blue Book users give the Soul a 4.5/5, praising the spacious cabin for a small car, but owners don’t like that there’s no all-wheel drive available for snowy roads.

What Common Problems Does the 2021 Kia Soul Have?

Common problems found on the 2021 Kia Soul include check engine lights, worn-out brakes, along with some excessive noise while turning. Overall, these problems are a bit worse than some other small SUVs on the market, leading to some higher repair costs if anything breaks.

Check engine lights are the most widespread complaint from 2021 Soul owners, showing up within the first 20,000 miles. Typically, the problem is caused by a sensor issue on the engine. You will need to use an OBD-II scan tool to read the code stored in the ECU, which can help diagnose the source of the problem. Once you know the source, fixing the problem costs $50 to $500.

Worn-out brakes are another problem mentioned by some Kia Soul owners at around 15,000 miles. The front brakes on models with larger wheels tend to wear out quickly. Changing out the brake pads costs around $150, while new rotors are an additional $400 if they have been damaged.

Excessive noise while turning is also a complaint from Soul owners within the first 1,500 miles. Usually, the problem is caused by the steering motor, or hitting the bump stops in the rack. Most dealerships can diagnose the source of the problem and fix it for free under warranty. If your Soul is out of warranty, then it’s around $400 to $750 to fix.

There is only one recall on the 2021 Kia Soul, which is better than some other small SUVs from the same year. The recall covers improperly heat-treated piston rings, which can cause the engine to fail. Kia will inspect and replace the pistons on affected models for free.

How Long Will the 2021 Kia Soul Last?

A well-maintained 2021 Kia Soul can last around 175,000 miles, which is shorter than other small SUVs like the Toyota RAV4. Regular annual maintenance costs are similar to other compact SUVs, according to data provided by Repair Pal, at $407 per year.

As a used 2021 Soul reaches 100,000 miles, and depending on the vehicle history report, owners should be prepared to replace the fuel filter for $170, the oxygen sensor costing $300, along with the radiator fan motor, which costs around $400.

How Is the Technology?

The standard entertainment technology is good, and includes a 7-inch touchscreen with Apple CarPlay and Android Auto connectivity. Optional upgrades include a larger 10.25-inch screen, and a premium Harman Kardon stereo system.

Standard safety technology is a bit worse than other SUVs, and features:

  • Rear-seat alert
  • Rearview camera

Optional driver assistance features include:

  • Forward collision warning
  • Pedestrian detection
  • Driver-attention monitoring
  • Rear cross-traffic alert
  • Adaptive cruise control
  • Forward automatic emergency braking
  • Lane-keep assist
  • Blind-spot monitoring
  • Lane-change assist
  • Head-up display

Is the 2021 Kia Soul a Good Value?

Yes, the 2021 Kia Soul is a good value if you’re in the market for a compact car with a practical hatchback, and fun driving experience. The blue book fair purchase price ranges from $17,275 to $25,995, making it less than a Honda CR-V or Subaru Crosstrek. When new, the price range was $17,590 to $27,650.

Paired with a continuously variable transmission (CVT), it achieves a combined fuel economy of approximately 30 MPG. This engine also enables the Soul to accelerate from 0 to 60 MPH in about 8 seconds, offering a balance of efficiency and responsiveness.
  • For those seeking more power, the Soul GT-Line Turbo comes equipped with a 1.6-liter turbocharged four-cylinder engine, producing a more robust 201 horsepower. This engine is mated to a seven-speed dual-clutch automatic transmission, enhancing driving dynamics. It achieves a slightly lower combined fuel economy at around 27 MPG. The turbocharged variant boasts a quicker 0 to 60 MPH time, clocking in at around 6.5 seconds, making it a more performance-oriented choice.

What Colors Does the Kia Soul Come In?

How Comfortable Is the Kia Soul?

The 2021 Kia Soul has been widely recognized for its comfortable and accommodating interior, which makes it a standout choice in its segment. One of the primary aspects contributing to its comfort is the spacious cabin, which is cleverly designed to maximize passenger comfort. The vehicle offers ample headroom and legroom both in the front and rear seats, making it suitable for passengers of varying heights. This spaciousness guarantees that even on longer drives, occupants can enjoy a relaxed experience. The seats themselves are designed with ergonomics in mind, providing good support and cushioning, which further enhances the comfort during travel.

In terms of ride quality, the Kia Soul impresses with its smooth and stable handling. The suspension system is tuned to absorb most road imperfections, providing a serene ride even on less-than-ideal road surfaces. This feature is particularly beneficial in urban environments where uneven roads and potholes are common. The vehicle also exhibits minimal body roll and maintains composure around corners, adding to overall comfort and confidence while driving. Additionally, the cabin is well-insulated from external noise, which contributes to a peaceful and quiet interior environment, allowing for easy conversation and an enjoyable audio experience.

Moreover, the 2021 Kia Soul includes various features that further elevate the comfort level. These include climate control options, which guarantee the interior temperature remains pleasant regardless of the weather conditions outside. Some models also come with heated seats and steering wheel, adding an extra layer of comfort during colder months. Overall, with its spacious and well-designed interior, smooth ride, and additional comfort features, the Kia Soul provides a delightful and comfortable experience for both the driver and passengers, making it an attractive option for a wide range of buyers.

How Much Storage Space Does the Kia Soul Have?

The 2021 Kia Soul stands out as a versatile and compact SUV, offering ample storage space designed to accommodate a variety of needs. The vehicle boasts a significant cargo area, providing about 24.2 cubic feet of room behind the rear seats. This space expands considerably when the rear seats are folded down, opening up to 62.1 cubic feet. These dimensions make the Kia Soul remarkably spacious for its class, allowing it to handle everything from daily errands to longer road trips with ease.

To put this space into perspective, the 24.2 cubic feet behind the seats can comfortably fit several large suitcases or grocery bags, making it ideal for airport runs or weekly shopping trips. For those needing more room, folding down the rear seats transforms the Soul into a cargo carrier capable of accommodating larger items like bicycles, a small piece of furniture, or even camping gear for outdoor adventures. The flexibility offered by the foldable rear seats adds to the practicality of the vehicle, making it a suitable option for a wide range of users, from families to adventure enthusiasts.

Additionally, the 2021 Kia Soul doesn’t just excel in offering sizable trunk space. It also includes various small interior storage spaces that are thoughtfully designed for everyday convenience. These include door pockets, a glove compartment, and a center console area, which are perfect for storing smaller items like phones, wallets, and water bottles. The inclusion of these storage spaces makes sure that passengers can keep their essentials within easy reach, enhancing the overall functionality and user experience of the vehicle. With its blend of generous cargo capacity and practical interior storage solutions, the Kia Soul emerges as an attractive choice for those seeking a compact yet spacious SUV.

What Are the Differences Between Years?

The third generation of the Kia Soul was launched for the 2021 model year.

2015: Standard rearview camera on all models, and optional leather seating is available.

2016: The Soul! model adds more safety features, including lane departure and forward collision warning

2017: Stronger turbocharged engine offered.

2018: Offers the same features as the 2017 model.

2019: No changes from earlier years.

2020: Fully redesigned for the third generation with new engines, technology features, and updated styling.

2021: Rear occupant alert system is standard on all models, updated suspension in the 2.0 X-Line and GT-Line models.

How Does the Kia Soul Compare to the Competition?

The 2021 Kia Soul is a decent small SUV if you’re in the market for something fun, but it does not last as long as some of the competitors on the market.

The Kia Sportage is a larger SUV offered by Kia, which costs around $3,000 more. Passenger room is better in the Kia Sportage, while the Kia Soul offers more responsive steering. We recommend the Kia Soul since it’s more unique, but both are decent small SUVs worth trying to see which you prefer.

The Toyota C-HR is another small SUV which costs about $2,500 more. Standard safety technology is better in the Toyota C-HR, while the Kia Soul offers more advanced entertainment features. We recommend the Toyota C-HR since it lasts longer, and has lower ownership costs as it ages.

Kia soul gt: a fun ride with just enough space.
The Kia soul gt line is fun to drive. It is very nimble, responsive, compact and has a very trendy/hip look. It is 4-cylinder engine leave much to be desired in terms of power, but it is sport semi-manual mode somewhat makes up for the lack of speed. However fuel is not the 30 mpg average that was advertised. It barely hits 11-16.5 on average, even when I am being extremely conservative with my driving. The price tag is moderate but could be a little lower seeing that the gt-line drives like the simpler iterations of the same model.

Performs very well. It's great on gas mileage and is very comfortable to drive. The seats sit a little low but don't create blind spots.

Car drives nice, it gets up and goes quite a bit more than the 2016 gen. 2 model. More electronic features like, blind spot monitoring and automatic bright headlights.
