2021 Kia Soul: Buy or Avoid?
The 2021 Kia Soul is one of the more dependable compact crossovers in its segment, offering robust value and impressive features for the money.

It's a generally solid car, but diligent maintenance and a thoroug…

2021 Kia Soul — Known Trouble Spots
The systems that tend to fail first on the 2021 Kia Soul, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
While improved over traditional CVTs, the IVT (Kia's version of a CVT) can develop internal wear, leading to whine, shudder, or reduced efficiency over time. Proper fluid changes are crucial for longevity.
Like many Kia/Hyundai models, the Soul's catalytic converter can be targeted for theft due to its precious metals content and relative accessibility. Additionally, some units may experience premature failure, potentially linked to engine…
Minor electrical gremlins can surface, including infotainment screen freezing, occasional Bluetooth connectivity issues, or intermittent sensor warnings (e.g., tire pressure). These are usually software-related or minor component failures.
2021 Kia Soul Mileage Danger Zones
The mileage windows when the 2021 Kia Soul most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Low Risk Zone
At this mileage, the vehicle is still relatively new, likely under its initial warranty, and issues are typically minor electrical glitches or early wear items like tires and brakes.
Maintenance Zone
This mileage often marks the end of the bumper-to-bumper warranty for the second owner. Key preventative maintenance, especially for the IVT, becomes critical to avoid future major repairs.
Elevated Risk Zone
Beyond 90k, the risk of component failures, particularly related to the powertrain and emission system, increases. The original powertrain warranty for the first owner is typically expiring around this point.
High Risk Zone
At this point, many components are at the end of their design life. Major repairs like transmission replacement become more likely if preventative maintenance hasn't been diligent.
2021 Kia Soul Ownership Cost Outlook
What it typically costs to keep the 2021 Kia Soul on the road. Full 5-year cost-of-ownership projection and major-failure-risk forecast are in the report.
Annual Maintenance
$400-600
Moderate Repairs
$500-1,500 occasionally
How Long Does the 2021 Kia Soul Last?
Focus on models with comprehensive service records demonstrating regular fluid changes, especially for the IVT. Low mileage is always preferable, but a well-maintained Soul at 60,000-80,000 miles can still be a sound purchase.
