About J&J Auto Service

J and J Auto Service has been a fixture in Fullerton, California for over 13 years, earning a 4.8-star rating across 181 reviews. The locally owned and operated shop serves drivers throughout Fullerton, Anaheim, and Placentia, handling everything from routine oil changes to brake replacements and complex diagnostics. Customers consistently praise the team's honesty, particularly highlighting that the owner personally reviews each vehicle and explains exactly what work is needed and what can wait.

What sets J and J apart is a commitment to honest assessment and transparent pricing that customers say is rare in the auto repair industry. Multiple reviewers specifically mention the owner declined to perform repairs that were not yet necessary, explaining that brake pads still had significant life remaining rather than pushing an upsell. The shop's AC condenser replacement work commands attention, with one customer noting a repair billed at under 400 dollars compared to a dealer quote exceeding 1,500 dollars. Rather than relying on generic service packages, the team tailors recommendations based on actual inspection findings.

Customer stories paint a clear picture of the experience. One reviewer described bringing in a Chevrolet Cruze with multiple diagnostic codes and finding the owner upfront about reasonable pricing from the start. Another customer recalled being told her mother minivan did not need brake pads despite already scheduling the work, with the technician showing her the measured thickness firsthand. Long-term loyalty runs deep, including at least one customer who has trusted the shop for 13 consecutive years and describes the owner as someone who consistently keeps customer interests paramount.

What Customers Say

Every one of the 181 reviews awards 5 stars, with zero negative ratings. Across the reviews, customers repeatedly mention three themes: pricing significantly lower than dealerships, honest assessments where the owner sometimes advises deferring repairs, and transparent communication. Specific praise targets the AC condenser work, brake pad inspections, and general maintenance services.
