Yes, in CA they do! If the vehicle came with a warranty or a service contract you may have protection under the lemon law or some other consumer protection law. Also, a new law going into effect on January 1, 2013, in CA will make all vehicles sold by a smaller buy here pay here (BHPH) lots carry a minimum 30-day warranty. This will help a lot of consumers who are most needy and who have been regularly ripped off in the sub-prime vehicle buying segment.
