Tune In & Tune Up

In-Person Smog Repair Events

If you are a San Joaquin Valley resident and you think your vehicle is in need of smog related repairs, bring it to the next scheduled Tune In & Tune Up in your area for a free emissions test.

If your vehicle fails our emissions test, you get a $500 voucher for emission-related repairs at a local STAR-certified smog shop. The $500 can only be used for diagnostics, smog testing, smog repair work, and certification.

We are only concerned about your vehicle emissions, not your personal life, so any data we collect is only used for internal reporting and is not shared with outside agencies.
