'zuverlässig' and 'die Zuverlässigkeit' are closely related, but they have different grammatical forms. 'zuverlässig' is an adjective and directly describes a person, a piece of information, or a thing: someone is reliable. 'die Zuverlässigkeit' is a noun and names the quality itself. Learners may confuse the words because both have the same basic idea: you can rely on someone or something. As a practical rule: with 'sein' (to be) or before a noun, 'zuverlässig' usually fits. When talking about the quality in general, 'die Zuverlässigkeit' is appropriate.
