A buyer can revoke his or her acceptance if it was predicated on a reasonable assumption that the goods' nonconformity would be cured, and the nonconformity was not cured.

Nonconformity

A deviation from a specified standard, requirement, or expectation, typically in the context of products, services, or actions not meeting prescribed criterions.

Revoke Acceptance

In legal terms, it's the act of formally withdrawing acceptance of an offer or agreement, often due to discovering defects or misinformation.

Reasonable Assumption

A premise made on the basis of apparent facts or evidence, considered to be logical or sensible under given conditions.
