Is The 2025 Kia EV9 Reliable? Here's What Consumer Reports Says

Why It Matters

Reliability flaws in a high‑priced EV can deter buyers and erode Kia’s credibility in the premium electric‑SUV market, potentially shifting demand toward more proven competitors.

Key Takeaways

• Consumer Reports ranks 2025 Kia EV9 among least reliable new EVs
• ICCU MOSFET failures cause limp mode and 12‑volt battery loss
• Issue affects 2‑10% of Hyundai and Kia EV owners on E‑GMP platform
• Recall issued for dual‑motor EV9 rear drive unit welding defect
• Pricing starts at $56,395, reaching $75,395 for top GT‑Line

Pulse Analysis

The 2025 Kia EV9 arrives at a time when three‑row electric SUVs are scarce, promising a spacious cabin, premium styling, and a price tag that starts around $56,000 and tops out near $75,000 for the GT‑Line. Kia markets the EV9 as a family‑focused alternative to the Tesla Model X and Rivian R1S, leveraging the Hyundai Motor Group’s E‑GMP architecture that underpins the Ioniq 5 and EV6. Early reviews praised its driving dynamics and interior quality, positioning the EV9 as a serious contender in the premium EV segment.

Consumer Reports, however, flagged the EV9 as one of the least reliable new EVs, primarily because of failures in the integrated charging control unit (ICCU). The ICCU’s MOSFET can overheat under high load, pulling a fuse and disabling the 12‑volt system, which may trigger limp mode or even a loss of power. Although the defect appears in only 2‑10 % of Hyundai and Kia E‑GMP models, the frequency is enough to drag the EV9’s reliability score below rivals such as the Rivian R1S. A separate recall addressed a welding flaw in the rear drive unit of dual‑motor versions, further denting confidence.

For prospective buyers, the reliability concerns translate into higher ownership risk, especially given the vehicle’s premium price. Kia’s standard warranty and an eight‑year, 100,000‑mile battery guarantee provide some mitigation, but the brand will need to demonstrate rapid fixes to preserve its reputation in the fast‑growing EV market. As competitors roll out more mature platforms, the EV9’s long‑term success will hinge on Kia’s ability to resolve ICCU issues and deliver consistent quality across its expanding electric lineup.
