I received an onboard alert that says Safety Restraint System Issue/Service is required. According to online Tesla Forums, this is a very common issue with the Model 3 drivers side air bag system. Although some relate it to a wire under the seat that becomes worn with movement of the seat, Tesla gives an estimate of over $1,000 to fix the problem. There repair estimate involves updating the front passenger airbag ($444), and replacing the occupant classification system ($426).
