2023 Hyundai Kona Complaints

Dear Hyundai Motor America Consumer Affairs, I am formally escalating a safety defect involving my 2023 Hyundai Kona, VIN [XXX] , purchased [XXX].

These changes created a safety risk because the vehicle no longer responded in a predictable way compared to its original performance.

Braking response became inconsistent, and the speed‑control system no longer behaved as it did before the service. The timing and behavior of forward‑collision alerts also changed compared to pre‑service operation. These changes created unpredictability in traffic, especially during following‑distance adjustments, stop‑and‑go situations, and sudden‑braking scenarios. The dealership did not provide t...
