NHTSA Complaint #11667442 — 2024 HYUNDAI SONATA

Vehicle: 2024 Hyundai Sonata. Current Mileage: 17,804 Primary Safety Defect: Electronic Stability Control (ESC) Steering Malfunction The vehicle's ESC system has a severe, intermittent malfunction causing unpredictable loss of steering control. This defect creates an extreme safety hazard. Occurrences include the vehicle veering unexpectedly towards highway medians and losing steering precision during turns and roundabouts, leading to multiple near-collision incidents. The vehicle is currently considered unsafe to operate. Relevant History: This ESC concern was subject to a manufacturer recall. An authorized Hyundai dealership performed the "ESC SOFTWARE LOGIC UPDATE (24-01-065H-1)" on June 6, 2025. Despite this specific recall repair, the severe ESC steering issue has persisted and recurred multiple times since that date, indicating a failure of the repair to permanently resolve the safety defect. Secondary Safety Defect: Inaudible Parking Collision Assistance The vehicle's parking collision assistance system is non-functional. Its audible warnings are inaudible and have never worked as designed since vehicle acquisition. This eliminates a critical safety feature intended to prevent low-speed parking collisions. Finally, The combination of a critical, recurring ESC steering defect, unaddressed by a recall repair, and a continuously inaudible parking collision assistance system, renders this vehicle highly unsafe to drive. Immediate investigation and permanent resolution are required.
