NHTSA Complaint #11690150 — 2016 HYUNDAI SONATA

I am submitting this complaint as a follow-up to my prior NHTSA complaint regarding the defective passenger seat Occupant Classification Sensor (OCS) in the 2016 Hyundai Sonata. Previous Tracking Number: 11689976 Since my initial submission, I have prepared a detailed technical and comparative report, which I am attaching here. The report documents how Hyundai’s repair policy for the OCS creates excessive repair costs (over $3,600 for a single sensor failure) and forces consumers to operate vehicles with compromised safety systems, in violation of the intent of FMVSS 208. The attached report provides: • Technical analysis of the OCS design and failure mode • Cost comparison with other manufacturers (Toyota, Honda, Ford, BMW, Mercedes-Benz) • Legal and consumer protection implications, including potential violations of the Texas Deceptive Trade Practices Act • Supporting exhibits (service estimate and parts documentation) I respectfully request that NHTSA review this additional evidence in connection with my prior complaint and consider appropriate regulatory or enforcement actions. Thank you for your attention.
