NHTSA Complaint #11703163 — 2025 CHEVROLET SILVERADO 2500

Following vehicle startup, the entire audio system defaults to a muted state, affecting all sound output channels. This includes, but is not limited to: ​Critical Safety Alerts: Seat belt warnings, system malfunction indicators, and door ajar chimes. ​Proximity and Collision Warnings: Parking assist chimes, Rear Cross-Traffic Alert (RCTA) warnings, and Backup Collision Intervention (BCI) alerts. ​Communication Systems: Navigation prompts and hands-free/Bluetooth call audio. ​The audio failure persists until manual user intervention or the next vehicle cycle, disabling critical warning redundancy. ​Safety Implications ​The system-wide audio failure directly compromises the safety of vehicle occupants and surrounding pedestrians in two primary ways: ​Risk to Pedestrians: The silencing of proximity and backup collision warnings (RCTA, BCI) removes a vital layer of redundancy, significantly increasing the risk of striking vulnerable road users, such as children, while maneuvering in reverse. ​Impaired Driver Safety & Compliance: The defect also removes essential alerts like seat belt warnings and renders the mandated hands-free communication system inoperable, forcing potential driver distraction or non-compliance with driving regulations. ​Conclusion ​This audio muting defect is a critical safety failure that disables mandated auditory warning systems, severely limiting the driver's ability to operate the vehicle safely and respond to immediate, unseen hazards. Immediate investigation and resolution are necessary.
