Is Kia More Reliable Than Subaru?
| Metric | Kia | Subaru |
|---|---|---|
| Avg Reliability Score | 73/100 | 73/100 |
| Models Tracked | 13 | 8 |

Kia vs Subaru: The Verdict
Call it a tie. Both brands rate good and both are trending better, so neither has a clear overall lead. The gap is in how they go wrong.
KIA is stronger on complaint severity, and its problems are spread across engine, electrical, and power train systems. Subaru is stronger on recall impact, with 121 recalls against 185 for KIA. Its complaints bunch up in one area instead: visibility and wipers make up about a third of them, and cracked windshields keep showing up. Repair costs are even in the overall comparison, though KIA's average estimate runs lower.
Where Kia and Subaru Differ Most
| Component | Weight | Kia | Subaru |
|---|---|---|---|
| Complaint Severity Owner complaints weighted by component severity | 35% | 64/100Good | 62/100Good |
| Repair Costs Annual maintenance and repair expenses | 30% | 72/100Good | 73/100Good |
| Recall Impact Safety recalls weighted by severity (park-it, park-outside) | 20% | 78/100Good | 84/100Excellent |
| Issue Diversity How many different systems have reported problems | 15% | 83/100Excellent | 79/100Good |
Where they diverge most: recall impact. Subaru has a 6-point edge in that component, which accounts for much of the reliability gap.

Who Should Buy Kia vs Subaru?
If you need a family hauler or want the strongest lineup depth, lean KIA. The Carnival is the best of the group, and the 2023 model year has far fewer complaints than 2022. Watch its power sliding doors, which keep closing on hands and arms, and its liftgate, which can drop partway after rising. The Niro and Sedona also rate excellent. Skip the 2022 EV6, which is tied to sudden loss of drive power from a failed charge control unit. The 2024 is the better EV6 pick.
If a lighter recall history matters most, lean Subaru. The Legacy and WRX top its lineup. Target a 2024 Legacy and skip 2019 and 2020, which draw the most trouble. The Ascent is a reasonable SUV choice in 2024, but avoid 2019. On any Subaru, check the windshield for cracks and test the touchscreen. On an Ascent, also check for a battery that drains while parked and a CVT that shudders or slips.
The Bottom Line: Kia or Subaru?
Buy on the model and year, not the badge. The KIA Carnival is the strongest vehicle across both lineups, and a 2023 is the one to find. KIA's average estimated repair cost is about $118 a year lower, or roughly $590 over five years. Choose Subaru if fewer recalls matter more, and inspect the windshield before you sign.
