A lemon car is a car, usually new, that may contain hidden mechanical flaws or defects discovered only after purchase. These cars may have repeated, unfixable problems, and every state in the United States has enacted laws to protect consumers who buy these cars.
Under most state laws, a car is classified as a lemon car if (1) it has a severe defect covered by warranty that was detected within certain time span after purchase or before a certain number of miles, and (2) it cannot be repaired after a reasonable number of attempts.
Based on state laws, the car buyer may be able to get a refund or a replacement for a lemon car. However, laws in most states recognize only new cars as lemon cars. Each year, about 150,000 cars turn out to be lemons. This is about 1 percent of all new cars produced that year.
