NHTSA Complaint #11716198 — 2012 HYUNDAI GENESIS

I am submitting this letter as a formal safety defect complaint regarding my 2012 Hyundai Genesis 5.0 sedan, which is experiencing braking system behavior that directly mirrors the defect described in Hyundai Recall Campaign 114 (NHTSA Campaign 13V489000), despite my vehicle not being included by VIN. Although excluded by VIN, the functional failure mode matches recalled vehicles, indicating the defect population may extend beyond the original VIN range. The vehicle exhibits the following symptoms: 1.Excessive and inconsistent brake pedal travel 2. Soft and spongy brake pedal feel 3. Highly variable brake biting point 4. Requirement to pump the brake pedal to obtain normal braking 5. Unpredictable brake engagement during normal driving These symptoms are intermittent and occur without warning, significantly increasing stopping distance and reducing driver confidence. The behavior is consistent with internal hydraulic or HECU malfunction, which the original recall attributes to corrosion caused by improper brake fluid formulation. I am particularly concerned because I am a disabled driver, and any reduction in braking reliability presents an elevated safety risk. Unpredictable brake response materially affects my ability to operate the vehicle safely and to respond to emergency conditions. While Hyundai has limited the recall to certain VIN ranges, Model Years Affected: 2009–2012 Hyundai Genesis sedans built April 30, 2008 – March 28, 2012. The braking behavior is functionally identical to recalled vehicles. This suggests the defect may not be limited to the originally identified production range and warrants further investigation. I respectfully request that NHTSA: 1. Review this complaint in the context of the existing recall 2. Evaluate whether the defect population should be expanded 3. Initiate further inquiry into VIN-excluded vehicles exhibiting identical symptoms 4. This issue represents a clear safety concern with potential for serious injury
