Owner Narrative

To Whom It May Concern, I am submitting this complaint to report a serious and potentially dangerous safety defect affecting my 2021 Tesla Model 3 Performance. After exposure to heavy rain or wet conditions, the vehicle’s horn completely stops functioning. The failure occurs regardless of the activation method—neither pressing the steering wheel horn nor using the horn via the mobile app produces any sound. The horn remains nonfunctional even though the vehicle is otherwise operable. This issue has occurred after the vehicle becomes wet due to rain and appears to be related to moisture intrusion or an electrical/design flaw. Once the failure occurs, the driver fully loses the ability to use the horn for warnings or emergency signaling. This is a critical safety concern. The horn is a federally required safety device and is essential for alerting pedestrians, cyclists, and other drivers to avoid collisions. Losing horn functionality significantly increases the risk of accidents, especially in urban driving, highway merging, and emergency situations where immediate warning signals are necessary. This issue is not isolated to my vehicle. Numerous Tesla owners have reported the same horn failure after rain or wet conditions on online forums and owner communities, indicating a widespread and systemic defect rather than isolated wear or misuse. Given the safety implications and the volume of similar reports, I respectfully request that NHTSA investigate this issue to determine whether a design or manufacturing defect exists and whether corrective action or a recall is warranted. Thank you for your attention to this matter. Owner – 2021 Tesla Model 3 Performance
