Star Auto Care on Chula Vista's Broadway is a California Bureau of Automotive Repair STAR-certified test-and-repair station providing smog inspections, gross-polluter diagnostics, and full mechanical service. The shop's BAR-97 emissions analyzers and OBD-II diagnostic scanners handle simultaneous vehicle testing, a throughput advantage on the high-traffic Broadway corridor near Broadway gas and wash and the Costco-Walmart retail stretch. As a C.A.P.-approved Consumer Assistance Program station, Star Auto Care performs state-subsidized emissions repairs for qualifying vehicles that fail their smog check. Bilingual service in English and Spanish covers the full inspection spectrum: gasoline tailpipe tests, diesel-opacity scans, OBD-II readiness verification, and brake-and-lamp safety certifications required for salvage-title vehicles. Extended multi-day catalyst replacements and fuel-system overhauls include courtesy referrals to Men In Black Transportation for interim vehicle access while post-repair drive-cycle monitors reset. The facility's most involved repairs target chronic P0420 and P0430 catalyst-efficiency codes, requiring downstream O2-sensor replacement, catalytic-converter installation with CARB-certified units, and post-repair drive-cycle verification.
