NHTSA Complaint #11666942 — 2014 HYUNDAI SONATA

Formal Complaint – Hybrid System Failure, Safety Risk (VIN: [XXX] | Hyundai Case #[XXX]) Dear Sir/Madam, I am writing to file a formal safety complaint regarding a dangerous incident involving my Hyundai hybrid vehicle (VIN: [XXX] ) and Hyundai Motor America's failure to respond meaningfully to repeated requests for assistance. Incident Summary: On [XXX], while driving with my two young children (ages [XXX] and [XXX] ), my vehicle suddenly displayed the following critical warnings: “Hybrid System Warning! Safely Stop and Do Not Drive” “Check Charging System” Immediately after these messages appeared, the car lost all power and came to a complete stop in the middle of the road. This created an extremely hazardous and distressing situation for me and my family. Although the vehicle is a few years old, it has very low mileage (38,345 miles), and I did not expect such a catastrophic failure. I submitted a report to Hyundai Customer Support on May 30, 2025 (Case #[XXX]) and followed up on June 9, 2025, but have only received an automated acknowledgment—no response, investigation, or support to date. Attachments: A video clip showing the warning messages at the time of the incident (I cannot upload the video clip since the option is not there, but I do have it if required) Requested Actions: A formal investigation into the safety and reliability of Hyundai's hybrid systems. A determination as to whether this incident qualifies under Hyundai’s warranty or federal safety defect regulations. Immediate contact from Hyundai with the next steps regarding inspection, resolution, or compensation. I am cc’ing Hyundai Motor America to ensure this matter is escalated appropriately and receives the attention it warrants. Thank you for your time and consideration. I look forward to your timely response. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
