Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

659 units potentially affected
The defect: Zero Motorcycles Inc. (Zero) is recalling certain 2020 SR/F and SR/S motorcycles. The front brake switch can fail from water getting into the switch.
The risk: An inoperable front brake switch will not illuminate the brake light when the rider applies the front brakes. Following vehicles may not realize the motorcycle is braking. Cruise control will not shut off with the application of the front brakes. Both conditions increase the risk of a crash.
The remedy: Zero will notify owners, and dealers will the replace the front brake switch, free of charge. The recall began November 30, 2020. Owners may contact Zero customer service at 1-888-841-8085. Zero's number for this recall is SV-ZMC-021-020.
