NHTSA Complaint #11524131 — 2023 TESLA MODEL 3

Software Version: 2023.12.10 Over the past month, I have experienced a recurring problem with my vehicle's auditory notification system. The issue first began a couple of software updates ago and has persisted through the most recent update. The problem manifests sporadically, having occurred three times within the past month. When this issue arises, all system sounds, excluding radio and media, cease to function for the duration of my ride and persist across all future rides until the vehicle is hard rebooted. There are no visible warning signs or error messages on the dashboard to indicate that the system sounds are malfunctioning. Proof of issue - https://youtube.com/shorts/VbDErQVVzp4?feature=share The malfunctioning system sounds include but are not limited to: 1. Forward Collision Warning Sounds 2. Seatbelt Warning Sounds 3. Blinker Indicator Sounds 4. EV Reverse Sounds 5. System Notifications 6. All alerts and warnings Attempts to Resolve the Issue: To temporarily rectify the issue, I performed a hard reboot on the vehicle's system. This measure restored the sounds, but the problem consistently returns. **Safety Concerns:** This issue poses a significant safety concern as the lack of audible notifications increases the risk of accidents, particularly due to the absence of forward collision warning sounds, seatbelt warning sounds, and blinker indicator sounds. Additional Observations: It is important to note that this issue began a few software updates ago and has persisted despite subsequent updates. There are no error messages or warnings on the dashboard when the auditory system malfunctions, making the problem harder to detect until an auditory notification is expected but not heard.
