Thanks to their shared platforms you’d assume that Hyundai and Kia’s reliability levels would be more or less identical, but as we uncovered in a recent article, this is not actually the case. We decided to see just what the differences were between the two by comparing competing models across some of the most popular body style segments.
To get a representative view of real-world reliability, we turned to owner feedback courtesy of Consumer Reports. Because it relies on data gathered from hundreds of thousands of vehicle owners and doesn’t accept advertising revenue or vehicles from automakers, the results are based purely on actual owner experience.
The results used for this comparison were the predicted reliability values for 2026 model year vehicles. These are compiled using existing reliability data from previous model years as well as preliminary information from owners for this year.
Compact Sedans
Hyundai
Kia
K4 vs. Elantra
The Elantra has been around since 2021, and has benefited from a mid-cycle refresh for 2024, giving Hyundai the opportunity to iron out minor glitches present in earlier production runs. Owners of 2023 through 2025 Elantra models had few complaints about the standard 2.0-liter engine and Intelligent Variable Transmission (IVT), although a few drivers reported minor infotainment screen glitches and occasional trim rattles.
The Kia K4 was completely redesigned for 2025, although it uses many components from the outgoing Forte, as well as sharing a platform with the current generation Elantra. That said, owners have experienced more electronic glitches and software bugs than in the Elantra, and that is partly why it contributes to a less than stellar 49/100 predicted reliability rating for 2026.
Midsize Sedans
K5 vs. Sonata
- Kia K5 Reliability Score: 51/100
- Kia K5 base MSRP: $27,490
- Hyundai Sonata Reliability Score: 58/100
- Hyundai Sonata base MSRP: $27,450
The midsize sedan segment sees Hyundai edge out Kia once again to take another victory. While the K5 was praised by several owners for its mechanical durability, there were complaints regarding intermittent Bluetooth pairing issues and finicky wireless phone chargers.
The Sonata underwent a significant styling and tech overhaul for the 2024 model year, and has seen strong reliability scores since then, with 2026 showing a slight dip, but still better than the class average. Aside from the usual minor tech glitches that seem to affect most new cars these days, the Sonata has proven to be a solid and ownership prospect.
Subcompact SUVs
Kia
Seltos vs. Kona
- Kia Seltos Reliability Score: 54/100
- Kia Seltos base MSRP: $24,990
- Hyundai Kona Reliability Score: 39/100
- Hyundai Kona base MSRP: $25,550
Kia takes the lead in the subcompact crossover segment with the Seltos. Updated for 2024 with revised styling and a new 8-speed automatic transmission for the turbo model, and an available dual 10.25-inch display, the Seltos has improved hugely on its initially dismal reliability ratings. Owners were impressed by the solid build quality and there have been very few drivetrain complaints.
The Hyundai Kona underwent a complete redesign for 2024, growing larger and significantly more high-tech. However, early production models have suffered from teething issues, with owners of 2024 – 2025 Kona models reporting frustrations with electronic driver-assist sensors issuing false warnings, wireless Apple CarPlay dropouts, and occasional hesitation from the base powertrain. These early issues should hopefully be resolved in the future, but for now, the Seltos is the clear choice when it comes to predicted reliability.
Compact SUVs
Hyundai
Kia
Sportage vs. Tucson
- Kia Sportage Reliability Score: 62/100
- Kia Sportage base MSRP: $28,790
- Hyundai Tucson Reliability Score: 67/100
- Hyundai Tucson base MSRP: $29,450
The compact SUV market is as tough and competitive as ever, and the Sportage and Tucson are the best-selling SUVs for these manufacturers in the US. Both models share the same underlying platform and mechanical components, but according to owner survey data, the Tucson is the one that is likely to give fewer problems in the year to come.
The results for these two models are close, though, and looking at data from the previous four years reveals that Hyundai manages to maintain its edge overall, with an average of 66 versus the Kia’s 61,75. Both models received strong positive feedback on their powertrains, with the most common issues focusing on driver assistance system issues and infotainment system glitches.
Three-Row SUVs
Hyundai
Kia
Telluride vs. Palisade
- Kia Telluride Reliability Score: 38/100 (2027)
- Kia Telluride base MSRP: $39,190
- Hyundai Palisade Reliability Score: 48/100
- Hyundai Palisade base MSRP: $39,435
Both the Palisade and Telluride have recently undergone a complete redesign, so the long-term reliability scores are a mix of old and new here. The Telluride skipped 2026, but it is back for the 2027 model year as a new model, promising more of everything, including its pricing. However, a move to a completely new platform, including the introduction of a turbocharged four-cylinder in place of the trusty old V6, and all-new in-car electronics has resulted in a sub-par 38/100 predicted reliability score.
The Palisade was redesigned for this model year, and retains its 3.5-liter V6, but has a completely new interior and exterior design. Its predicted reliability score is actually better than the previous generation model could achieve in 2025, but it is still nowhere near class leaders like the Toyota Highlander and Grand Highlander which both scored in the high 60s and low 70s. Compared to the Telluride, though, it is slightly less likely to be a maintenance headache in the long run.
So Which Brand is The Most Reliable?
| Segment | Kia Model | Score | Hyundai Model | Score |
| Compact Sedans | K4 | 49 | Elantra | 57 |
| Midsize Sedans | K5 | 51 | Sonata | 58 |
| Subcompact SUVs | Seltos | 54 | Kona | 39 |
| Compact SUVs | Sportage | 62 | Tucson | 67 |
| Three-Row SUVs | Telluride | 38 | Palisade | 48 |
| Totals | Average | 50.8 | Average | 53.8 |
With Hyundai and Kia sharing much of their mechanical and electronic components, the overall results across five of the most hotly contested segments are unsurprisingly close.
Certain models, like the Telluride and Palisade, are mechanically different enough to show a clear difference in predicted reliability scores, but most with similar underpinnings deliver comparable results. And remember that sticking to prescribed maintenance schedules becomes ever more important as a vehicle ages.
When considering a new purchase, both brands have the same standard-setting warranties and the constant improvements and upgrades over the model years tend to translate into better products overall, making either one a good choice when it comes to long-term durability. Hyundai wins this contest, but by the narrowest of margins.
