NHTSA Complaint #11695969 — 2025 TESLA MODEL 3

On my 2025 Tesla Model 3 Highland, the right-turn signal button on the steering wheel fails to activate approximately 25–30% of the time. The issue is random and unpredictable. This has occurred while changing lanes on the freeway and when turning into shopping centers or side streets, leaving drivers behind me unaware of my intent and creating a safety hazard. The problem is worse when lane assist is active, as the vehicle resists the maneuver when the signal doesn’t engage, interpreting it as lane departure. The problem started happening at around 3,000 miles on the odometer and continues intermittently. I have not had Tesla service confirm the issue yet, but other owners have reported that replacement of the steering wheel does not resolve it, suggesting a systemic or software-related defect. No warning lamps or messages appear.
