Smog Checks

We perform California Smog Checks and STAR Smog at our Chula Vista shop. We do both, and we can help diagnose and repair vehicles that need work to pass.

Smog Check and STAR Smog — we do both

OREC Imports is a California Bureau of Automotive Repair (BAR) STAR Smog Station, and we also perform regular California Smog Checks. Bring your DMV registration renewal notice — whichever type your car needs, we’ll take care of it.

We’re also CTC (Clean Truck Check) credentialed for the emissions side of the heavy-duty vehicle program. We do not service diesel engines.

Who needs a smog check in California

California requires a smog check at certain registration intervals for most vehicles. New residents have a window after registering a California vehicle to obtain a check (when one is required).

Common exceptions:

  • Newer vehicles within their early renewal cycles
  • Electric vehicles
  • Motorcycles

Smog failure diagnosis and repair

If your vehicle hasn’t passed a smog check, we can look into the cause. Common contributors include:

  • Oxygen sensor issues
  • Catalytic converter condition
  • Evaporative emissions (EVAP) system leaks
  • EGR system issues
  • Engine misfires affecting the catalyst

We’ll identify the cause, provide an estimate, and — after the repair — perform the retest.
