Under the North Carolina Lemon Law, a vehicle is a lemon when, after a “reasonable” number of repair attempts, a manufacturer is not able to fix a defect that began within the first 24 months or 24,000 miles of ownership. Generally, a reasonable number of repairs is considered four or more for the same problem, or if the vehicle has been out for repair for more than 20 days within a twelve-month period of the warranty. The problem also has to substantially impair the vehicle’s value to the consumer.
