Complaints
One complaint can name several systems, so shares can add to more than 100 percent.
Confidence is the model's own probability for the label it chose (0 to 1), not accuracy.
Model-generated labels on tagged complaints only. Model years 2013 and newer are tagged in full; 2012 in part (see tagged_share); earlier model years have no tags. NHTSA's own flags remain separate in the complaints block.
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.
Consequence: 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.
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.
Do not drive: No. Park outside: No.

Notes on this record
Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
