I bought a car from a used car lot 3 days ago "as-is". I discovered the check engine light was either removed or burnt out.

The following text comes from the website of the Washington State Office of the Attorney General: [BEGIN QUOTE] "As Is" Most used vehicles are offered by dealers "as is." If you explicitly negotiate and knowingly accept such an offer, you give up your implied warranty of merchantability. Nothing in any law requires you to sign a waiver of your implied warranty rights under any circumstances. You waive the implied warranty only if: The dealer explicitly discussed warranty terms with you You are accurately informed of the consequences of purchasing the vehicle "as is" (i.e. the waiver lists the particular qualities and characteristics of the vehicle that will not be covered) You do not purchase an extended service contract; and finally, You knowingly and voluntarily assume all risk for costs of repairs due to defects in the vehicle. If you waive the implied warranty and the vehicle breaks down, you will be responsible for all repairs! If the vehicle breaks down one minute or one mile from the dealership, you will still be responsible for all repairs! Buying a vehicle "as is" means you are assuming all responsibility for the repair and maintenance of the vehicle! As an informed buyer, you should consider whether negotiating away your implied warranty rights is really in your best interests. Buying a car "as is," you will not have any warranty and little if any recourse against the dealer if the vehicle turns out to have substantial problems. [END QUOTE] Hope this helps.

A sale "as is" is one in which the dealer makes no promises about the car's condition or future performance, but "as is" is not a defense to fraudulent misrepresentation or active concealment.
