The 2020 Zero SR/F has 3 recalls, all involving brake safety: rear rotor bolts that were not fully tightened can loosen and damage the caliper or swingarm, reducing stopping power, and a front brake switch that can fail from water intrusion and leave the brake light dark.
The loose rear rotor bolts may produce an audible noise as they contact the swingarm, but whether or not a rider notices that warning, the real risk is reduced rear braking and a longer stopping distance. The front brake switch issue is a visibility concern for other road users: when the switch fails, applying the front brake gives no signal to following traffic that the motorcycle is slowing.
