What Is Considered A Substantial Impairment?

The Lemon Law only covers serious defects—those which substantially impair the use, market­value or safety of the vehicle. The law does not list the defects which are considered substantial. You must be able to demonstrate specifically how the use, safety or market value of your vehicle is substantially impaired by the defect. For example, to prove market value impairment, you must show that your vehicle is worth at least 10 percent less than it would be without the defect. Although a defect may be annoying, it is not necessarily substantial.

The information on this page is meant to provide a general overview of the law. The laws in your state and/or city may deviate significantly from those described here. If you have specific questions related to your situation you should speak with a local attorney.
