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: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2016-2018 Toyota Prius vehicles. A portion of the engine wire harness connected to the hybrid Power Control Unit (PCU), could contact the cover at this connection and wear, causing an electrical short circuit.
Consequence: An electrical short can increase the risk of a fire.
Remedy: Toyota will notify owners, and dealers will inspect the engine wire harness assembly and replace it if damage is found. A protective sleeve or protective tape will be included to prevent any future damage. These repairs will be performed free of charge. The recall began October 30, 2018. Owners may contact Toyota customer service at 1-888-270-9371. Toyota's number for this recall is J0T.
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.
