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.
Date: 2020-12-11. Systems: ENGINE, ENGINE AND ENGINE COOLING.
Defect: Kawasaki Motors Corp., U.S.A. (KMC) is recalling certain 2021 Z400 ABS (ER400D), Ninja 400 (EX400H) and Ninja 400 ABS (EX400G) motorcycles. The strength of the camshaft chain tensioner may be insufficient due to improper heat treatment, possibly causing it to be damaged.
Consequence: A damaged camshaft chain tensioner can cause the engine to stall, increasing the risk of a crash.
Remedy: KMC will notify owners, and dealers will replace the camshaft chain tensioner, free of charge. Note: Owners are advised to not ride their motorcycles until the repair has been completed. The recall began December 21, 2020. Owners may contact KMC customer service at 1-866-802-9381. KMC's number for this recall is MC20-13.
Do not drive: Yes. 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.
