These vehicles and other goods are called “lemons.” The federal lemon law (the Magnuson–Moss Warranty Act) was enacted in 1975 and protects citizens of all states. State lemon laws vary by state and may not necessarily cover used or leased cars, and other goods. The rights afforded to consumers by lemon laws may exceed the warranties expressed in purchase contracts. Lemon law is the common nickname for these laws, but each state has different names for the laws and acts.
Federal lemon laws cover anything mechanical. The federal lemon law also provides that the warranter may be obligated to pay the prevailing party’s attorney in a successful lemon law suit, as do most state lemon laws. - http://en.wikipedia.org/wiki/Lemon_law
