secret warranty program

Definition from Nolo’s Plain-English Law Dictionary

A program under which a car manufacturer will make repairs for free on vehicles with persistent problems, even after the warranty has expired, in order to avoid a recall and the accompanying bad press. Secret warranties are rarely advertised by the manufacturer, so consumers must pursue the manufacturer to discover and take advantage of them. A few states require manufacturers to notify car buyers when they adopt secret warranty programs.
