ZERO SR Recalls

The Zero SR has 4 recalls spanning 2014 through 2022, with the most serious being a front brake caliper bolt issue on 2022 models where incorrectly installed bolts can damage the fork's mounting threads, allowing the caliper to loosen and reduce braking force. The 2015 model year has a power converter that can lack sufficient output during high electrical demand, causing the anti-lock brakes and all vehicle lights to cut out simultaneously during a braking event. Going back to 2014, the motor rotor on certain examples can make contact with the stator at sustained high RPM, which can lock the rear wheel without warning while riding.
