My truck went down in one of the busiest intersections in Costa Mesa at 5pm. I hurried to aid my crew in assessing the issue with the truck. After a few calls I'm connected with Precision Diesel,Eric P came out in no time flat and found the issue and resolved it within 5 minutes. Saved me money on a tow and a repair. I've found the mechanics I'll call from now on.
