Did you know the typical “extended warranty” is not a warranty at all, but, a “service contract?” Still, even a short service contract of 30 days or more may help you get coverage under the CA or FED lemon laws. If a dealer sells you a “service contract” an “implied warranty of merchantability” may well attach and if so, that dealer could be on the hook under the lemon law. If the dealer uses the word warranty or it is written somewhere in the sale documents, you have an express or a written warranty and you should have lemon law protection.
Be sure to know what your “extended warranty” covers and does not cover. If it is breached, then you may have some alternative protection(s).
