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: General Motors LLC (GM) is recalling certain 2018 Chevrolet Sonic vehicles. A joint in the driver's seat-back frame may not be properly welded, reducing the strength of the seat-back frame.
Consequence: In the event of a rear-impact crash, the seat-back may fail, increasing the risk of injury.
Remedy: GM will notify owners, and dealers will replace the driver's seat-back, free of charge. The recall began June 28, 2018. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 18178.
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.
