about
nx_underbuilt_fetch.nx -- R6 of the CAD car-twin ladder (nx_cadtwin_census P6b): bank the REAL NHTSA
complaints + recalls JSON per vehicle = the raw "this part is underbuilt on this model" flip signal.
Operator 2026-07-07: rebuild cars + identify underbuilt parts when flipping. NOBODY benchmarks
failure-prone-part prediction publicly (cadtwin research finding) -- this data lane DEFINES ours.
VEHICLE SET = DATA (grow by adding rows): 2013 Nissan Altima (CVT era) / 2011 Chevy Cruze (engine/
cooling era) / 2016 Honda Civic. Complaints can be thousands of records -> 16MB buffer.
API: api.nhtsa.gov complaintsByVehicle + recallsByVehicle, public, no key (probed 2026-07-07).
