An interesting facet of the Wisconsin Lemon Law is that it makes a difference between minor and major malfunctions. You are eligible to apply for compensation or refund or replacement claim under the lemon law only if your vehicle has a serious, that is a major malfunction. So it's no use crying foul if your car has a broken headlight or something equally inconsequential.

And speaking of the major and minor malfunctions, it is always worth knowing the nonconformities of the Wisconsin Lemon Law. They are:

- Conditions that do not affect the use, worth or safety of the vehicle,
- Items not covered by the manufacturer's warranty,
- Situations like poor acceleration of a vehicle with a small vehicle or when heavy steering has been employed on a vehicle without power steering,
- Conditions arising out of incorrect maneuver, misuse, neglect or unauthorized alterations to the setup.
