NHTSA complaint #11715496

Owner complaint summary

At approximately 30,000 miles, the front left suspension lateral link/control arm separated while driving due to a missing mounting fastener (bolt), resulting in sudden steering instability and abnormal front wheel movement. Vehicle handling became unpredictable and felt unsafe to control, creating risk of loss of steering control. I stopped driving immediately. There was no collision, curb strike, pothole, or road hazard at the time of the incident. No warning lights or messages appeared prior to the failure; it occurred suddenly without advance notice. Tesla Service inspected and confirmed the separation and missing fastener. Suspension components and the front subframe assembly were replaced —4,400 out of pocket. Tesla documented they could not make a formal cause determination. The recovered bolt is intact and available for inspection upon request. Insurance also reviewed the incident and classified it as mechanical rather than collision-related. Because this involves a safety-critical steering/suspension fastener failure without warning, I am submitting this report for safety tracking. I am aware of similar owner reports describing suspension fastener or lateral link separation on this vehicle generation in case this reflects a broader pattern.
