Scheduled maintenance is fast, safe, and efficient, helping minimize downtime in Southern California’s demanding operating environment.

Supported by 65,000+ emergency service providers, Cox Fleet delivers rapid roadside service across Southern California. Whether a truck is down on the 710, facing delays on the 5, or stuck in desert logistics corridors, we coordinate service end-to-end and audit every invoice — ensuring clarity, speed, and quality.

Our preventative maintenance programs follow OEM standards and operational schedules. Services include:

• Oil & fluid changes

California’s stop and go traffic, heat, and long haul demands make preventative maintenance essential to reduce downtime and extend vehicle life.
