Authorized Bureau of Automotive Repair Smog Check & Repair Center
123 Auto Center is an authorized Bureau of Automotive Repair (BAR) smog check and smog repair center in Upland, CA. We don't just test your vehicle — we specialize in diagnosing and repairing vehicles that have FAILED their smog check inspection. If your car or truck didn't pass, bring it to us. We'll identify the problem, fix it, and get it ready to pass with confidence.
Did your vehicle fail its smog check? You're not alone — and you're in the right place. Unlike test-only stations that can only pass or fail your vehicle, 123 Auto Center is fully licensed to perform both smog inspections AND smog repairs. Our experienced technicians use advanced diagnostic equipment to pinpoint the exact cause of your emissions failure, whether it's a faulty oxygen sensor, catalytic converter issue, evaporative system leak, or engine performance problem. We repair it right the first time and re-test on site — no need to go anywhere else.
