Hyundai typically offers an 8-year or 100,000-mile warranty on the high-voltage battery, covering defects and significant capacity loss. Check your warranty documentation to confirm the coverage details.
To request a battery replacement, schedule an appointment at an authorized Hyundai service center. Explain the range drop and request a battery health check.
The service center will likely perform diagnostics, including a battery capacity test, to determine if the battery has degraded beyond the acceptable threshold (usually 70% or less of its original capacity).
If the service center is not cooperative or denies your request, escalate the issue by contacting Hyundai's global customer support at 1-800-633-5151 or through www.hyundai.com.
Present all documentation, including test results and communication records, to strengthen your case for a warranty replacement.
