SERVICE BRAKES,FORWARD COLLISION AVOIDANCEVehicle purchased 9/1/24 from Courtesy Hyundai of Tampa. Dealership failed to file registration/tags until 10/4/24. 7/12/25: Vehicle experienced involuntary acceleration and braking, resulting in impact with my mother’s home. 7/16/25: Dealer issued written report stating vehicle was operating normally and documented a recall-related display/audio/camera software update. 8/14/25: Hyundai engineering inspection performed without my knowledge. No report has ever been released. 8/27/25: Hyundai issued corporate denial, blaming driver error and stating braking/acceleration systems were normal. 12/5/25: Second involuntary braking incident at highway speed on I-275. Five uncommanded braking events over ~20 miles. Service Manager stated failure was due to sensor/camera malfunction and instructed that the vehicle should not be driven and to tow immediately. Despite this, the vehicle had been released into roadway operation. VIN lookup shows an open, unrepaired federal recall (24V879000 / Recall 271) for the rearview camera system, marked Recall Incomplete, despite the dealer’s documentation that recall-related camera/software work was completed on 7/16/25. BBB Auto Line denied my claim only because the vehicle was outside Florida Lemon Law eligibility. No safety determination was made. Hyundai released no engineering, sensor, or camera data despite an engineering inspection. This vehicle has experienced repeated involuntary braking and acceleration at highway speed, involving braking, camera, and automatic emergency braking systems, creating a serious risk of loss of control, collision, injury, or death. Despite repeated failures, contradictory diagnostics, withheld engineering data, and an open federal recall, the vehicle was released back into public roadway operation. I request that NHTSA formally investigate this safety defect.
