Complaint title: defective horn system on 2026 Tesla Model 3 - ineffective in rain or highway conditions description: the horn on my 2026 Tesla Model 3 highland is dangerously inadequate. It uses a single pedestrian warning speaker instead of a proper horn, which is easily overpowered by road noise, tire noise from large trucks, and especially rain. I cannot reliably alert other drivers, including 18-wheelers, when they are drifting into my lane or failing to yield. This creates a serious safety risk in wet conditions and highway driving. Traditional horns have been effective for decades — this design fails basic safety expectations. I am requesting immediate investigation and a fix.
The contact owns a 2026 Tesla Model 3. The contact stated that while driving 35 mph with the autonomous self-driving feature enabled, the vehicle was driving in the left-turn lane and jerked over into the oncoming traffic. The failure mileage was approximately 9,999.
