7 recalls across 5 model years
The Zero SR has 7 recalls spanning 2014 through 2022, with the most serious recent issue affecting 2022 models where incorrectly installed front brake caliper bolts can damage the fork threads, allow the caliper to loosen, and reduce braking effectiveness.
The 2022 model year also has a separate recall for incorrect rear brake pads that may not perform as intended, further reducing stopping ability. On 2021 models, the DC-DC converter can run out of capacity when the anti-lock brakes, instruments, lights, and any connected accessories are all drawing power at once, causing the converter to shut off and disabling all of those systems simultaneously while riding.
The same DC-DC converter power shortage affected 2015 models, where insufficient output during high demand could cut power to the anti-lock brakes and all lights at the same time. A related filing for 2015 covers the same underlying issue through the power converter that feeds the brakes, instruments, and accessories. Going back to 2014, the motor rotor can contact the stator at sustained high RPM, which can cause the rear wheel to lock up without warning.
The 2018 model year has a compliance recall for an emissions label that may state the wrong model year, which could cause owners to miss a future safety notice.
