    • Must agree to all program terms & conditions before receiving a voucher.
    • Must not have used a voucher with a repair date less than twelve months.
  • The following is a step-by-step process for how to redeem your voucher:
    • You can receive a smog repair voucher by attending an In-Person Event or contacting the 1-800-806-2004 call center.
    • Schedule an appointment with a participating STAR test-and-repair station.
    • The smog station with your authorization will perform a smog check inspection to determine your eligibility for repairs.
    • If your vehicle passes the smog check inspection, you will receive a certificate of compliance.
    • If your vehicle fails the initial inspection test for eligible repairs, the shop will then continue with the second emission tail pipe test (only for 2000 and newer vehicles). The shop will then perform a diagnostic to determine the reason for the smog failure.
    • The shop will follow up with the results of their diagnostics and provide you with an estimate of the cost of repairs.
    • You will need to approve or decline the needed or suggested repairs to move forward in the process.
    • Once you approve repairs and agree to any out-of-pocket expenses, you will be required to issue such payment upon picking up your vehicle.
    • Please note, the repair process may take up to 3 to 5 days. We recommend that you understand and review all the details before you give authorization to the shop to proceed forward.
    • If you decline repairs, the program will cover the cost inquire from the testing and diagnostics performed by the shop. If you need additional time to authorize your repairs, we recommend that you return within 90 days to avoid possible additional tests and diagnostics fees.
