Lemon laws have now been enacted in all but 2 states. While these lemon laws  are not uniform, they do follow a common theme.  
- The statutes define lemon cars and required that manufacturers (not  dealers)remedy the defects. Most statutes define "lemon-ness" in terms of a car  that continues to have a defect that substantially impairs its use, value, or  safety of the car after a reasonable number of attempts to repair the car.  
 - Most statutes set up a warranty rights period of either 12 to 24 months or  12,000 to 24 thousand miles. The defects must occur sometime in this period.  
 - Most of the statutes contain a three or four prong definition of when a  manufacturer has had a sufficient number of attempts to repair, entitling the  consumer to a refund or a replacement. These are: 
- If the defect is a serious safety defect involving brakes steering, the  manufacturer is granted one attempt to repair.  
 - If the defect is a safety defect not involving a serious safety defect, the  manufacturer has two attempts to repair.  
 - For any other defect, the manufacturers are usually granted three or four  chances to repair the same defect.  
 - If at any time the vehicle is in the shop for a cumulative total of 30 days  in a one year period, at least one of those days occurring in the first 12  months or 12,000 miles. 
 
 If any of the four prongs are satisfied, the consumer is generally granted  the right to require repurchase or replacement of her vehicle.
  - Most lemon laws allow an offset for use of the vehicle for the consumer.  This reasonable offset for use, often involved a reduction in the consumer's  purchase price return in relation to the number of miles he has put on the car.  One law expresses the reduction in refund for use as follows: 
(miles at time of refund x purchase price)/100,000
 The consumer can often effectively argue that he should not be charged for  miles that were put on the vehicle after the initial attempt to repair the  offending defect. For example, what if the consumer allows a dealer to make  several attempts to repair a defect over a period of several thousand miles?  Should the manufacturer be allowed to reduce his refund for the period of time  he was unsuccessful in repairing the defect? Our answer is no and the above  formula should be computed using the mileage at the time of the first attempt.  This can often make a difference of several hundred dollars to the consumer.
  - Only about one half of the lemon laws allow the consumer to recover  attorney's fees in his action. Those states that do allow attorney's fees  certainly provide greater access to representation in warranty disputes and  greater likelihood of success.
