- Hyundai recalled Ioniq 5 and 9 for a battery pack issue.
- Some high-voltage busbars may not be torqued correctly.
- Faulty bolts could lead to fire risk or fail-safe mode.
Hyundai is recalling two of its newest electric models, the Ioniq 5 and Ioniq 9, in the United States due to a potential fire risk stemming from a battery defect. Both models are currently produced at the company’s plant in Georgia.
According to Hyundai, the issue involves the battery pack’s internal components and could increase the risk of electrical fire if not addressed. Specifically, a recall notice points to improperly tightened high-voltage busbars during assembly.

If the retention bolts work loose over time, this could lead to electrical arcing within the battery pack, which in turn may trigger a fire. Hyundai also notes that these loose connections could disrupt voltage readings, pushing the vehicle into a fail-safe operating mode.
How Many Vehicles Are Affected?
The recall affects a very limited number of vehicles. Hyundai has identified 21 units of the Ioniq 5 from the 2025 to 2026 model years, built between January 24 and September 8, 2025. Additionally, just six Ioniq 9s produced from April 8 to September 12, 2025, are impacted.
The issue was first identified in November, when Mobis North America Electrified, Hyundai’s in-house battery supplier, discovered a battery system assembly unit that failed a quality test. The root cause was traced to under-torqued busbar bolts. By December, Hyundai had compiled a list of potentially affected VINs, and the recall decision followed in January.
Hyundai has confirmed that no related incidents have occurred in the field. So far, there have been no reports of crashes, fires, or injuries linked to the issue.
Starting April 6, Hyundai will notify both owners and dealers. The fix is straightforward. Dealers will inspect the busbar bolts in the battery system assembly and tighten them if necessary.
