What does faultiness mean?
Faultiness is an abstract noun denoting the condition of being faulty — that is, of containing defects, flaws, or imperfections. Where a single crack in a machine part would be called a fault, faultiness describes the broader state of a thing that is prone to or characterized by such faults. The word appears most often in formal, technical, and evaluative contexts: engineering reports may cite the faultiness of a design, and philosophical writing may refer to the faultiness of human judgment or memory. It carries a neutral to mildly negative connotation, pointing out inadequacy rather than assigning blame. Derived from the adjective "faulty" by addition of the suffix "-ness," it belongs to a family that includes "faultlessly" and "faultlessness" on the opposite side of the scale. Though less common than its relatives, it offers a precise way to name defective quality as a property rather than a countable list of individual flaws.

Every time you say "find fault," you're echoing the same Latin root — fallere, "to deceive" — that hides inside "faultiness."

Etymology of faultiness
"Faultiness" is formed within English from the adjective "faulty" plus the noun-forming suffix "-ness." The root word "fault" entered Middle English from Old French "faute," itself from Vulgar Latin *fallita, ultimately traceable to the Latin verb "fallere," meaning to deceive or disappoint. This Latin root also gave English "fail," "fallacy," "default," and "unfailing," making "faultiness" part of a large family of words concerned with deception, shortfall, and imperfection.
