- The Tanner Consumer Protection Act (Civil Code 1793.22) covers new motor vehicles sold or leased in California under the manufacturer's original warranty.
- Within 18 months or 18,000 miles, whichever comes first, a reasonable number of repair attempts is presumed if: the same serious safety nonconformity was repaired 2 or more times with manufacturer notice; the same nonconformity was repaired 4 or more times with manufacturer notice; or the vehicle was out of service for repairs more than 30 calendar days in total.
- If a qualified third-party dispute resolution process exists and you were told about it in time, you generally must use it before asserting the presumption in court.
- DCA's Arbitration Certification Program (ACP) certifies and monitors those programs. Not every manufacturer has a state-certified program. New Motor Vehicle Board mediation: (916) 445-1888.

ACP describes the Lemon Law as applying to new vehicles sold or leased in California that are still under the manufacturer's original warranty. If the dealer or manufacturer cannot fix a warranty issue after at least two attempts, they must replace the vehicle or refund it. ACP arbitration is cost-free to consumers when a certified program exists. (source: California Department of Consumer Affairs)
