About this index
The National Highway Traffic Safety Administration collects safety complaints from vehicle owners through its Office of Defects Investigation. Each complaint records the make, model and year, the affected component, whether a crash, fire or injury was involved, and the owner’s description of the problem. This Kapa index covers complaints filed in 2026, mirrored for agent search. It is not a complete NHTSA archive.
