THE DIFFERENCE BETWEEN LEMON LAW AND AUTO FRAUD Typically, California Lemon Law claims involve vehicles which the manufactur cannot repair to properly comply the the terms of its warranty after a reasonable number of repair attempts.  With automobile fraud, there is oftentimes an issue not with the warranty on the vehicle, but concerned with the sales transaction of the auto, boat, or rv. Many attorneys who practice lemon law also engage in auto fraud matters.  Other lemon law attorneys limit their practices exclusively to auto lemon law warranty claims.
