Automobile warranties come with a wide range of protections and limitations, and can apply to new or used cars. While manufacturers typically offer express warranties (written guarantees) with all new car purchases, implied warranties and verbal guarantees can also be made a part of a vehicle warranty. Your car may be covered under a range of warranties and protections whether you purchased it new or used.
There are a number of laws that govern auto warranties for new and used cars at the federal and state level. Whereas state laws vary from state-to-state, federal laws are applicable everywhere whether the state laws are more stringent or less so. The primary federal law concerning auto warranties and consumers' rights is the Magnuson-Moss Warranty Act. However, the Uniform Commercial Code, which addresses contracts, also applies and there are other federal statutes and regulations, which address specific vehicle issues such as those requiring emission controls.
