Emergency Roadside Assistance for Semi-Trucks and Big Rigs

Heavy-duty trucks face demanding conditions every day and roadside failures are sometimes unavoidable. Our emergency roadside assistance for semi-trucks and big rigs is designed to get drivers moving again as safely and efficiently as possible.

We assist with common roadside breakdown scenarios including engine no-start conditions, sudden power loss, overheating, electrical faults, sensor failures, fuel system problems, and after-treatment system derates. With manufacturer level diagnostic software and hands on diesel experience, our technicians quickly identify the root cause of the problem and determine whether roadside repair is possible.

When on-site repair can restore operation, we focus on safe, lasting fixes, not temporary patches that fail miles down the road.

Emergency Roadside Assistance for Commercial Fleets

Fleet downtime disrupts schedules, impacts customer commitments, and increases operating costs. California Mobile Fleet provides emergency roadside assistance for commercial fleets operating throughout Southern California.

Our roadside fleet services are designed to support multiple units, urgent dispatch needs, and clear communication with fleet managers. We understand teh importance of documentation, accurate diagnostics, and reliable repairs that minimize repeat breakdowns.

Whether your fleet operates locally or regionally, our roadside assistance services help keep drivers safe and freight moving using our mobile diesel repair expertise.

RV Emergency Roadside Assistance and RV support

Roadside breakdowns don’t just affect commercial trucks, they can completely derail RV travel plans. California Mobile Fleet offers emergency RV roadside assistance for motorhomes and recreational vehicles.

Our mobile technicians provide roadside support for RVs experiencing engine trouble, electrical issues, cooling system failures, warning lights, or after-treatment system issues. We bring the same professional expertise used for commercial trucks to RV roadside emergencies.

If on-site repair isn’t possible, we coordinate safe  RV towing using heavy-duty equipment, ensuring your motorhome or RV is handled properly and transported securely.

On-Site Roadside Repair vs. Towing Support

One of the biggest advantages of professional roadside assistance is determining whether a vehicle can be repaired on-site or requires towing.  California Mobile Fleet focuses on accurate assessment and honest recommendations.

Whenever possible, we perform repairs roadside to reduce downtime and costs. If towing is required, we arrange heavy-duty towing services for semi-trucks, trailers, and RVs using appropriate equipment to prevent further damage.

Our goal is always the same: get you back on the road safely or transported efficiently for further repair.

Advanced Diagnostics During Roadside Assistance

Modern roadside assistance goes beyond basic tools. California Mobile Fleet uses advanced diesel diagnostic software  to quickly identify faults that can’t be diagnosed visually.

We support roadside diagnostics for major diesel engine platforms including Cummins, Detroit Diesel, Volvo, Mack, International, PACCAR, Hino and Isuzu, as well as Allison and Eaton transmission systems. This capability allows us to resolve complex issues more efficiently, even during roadside emergencies.

Accurate diagnostics reduces guesswork and helps prevent repeat failures.

Roadside Assistance for Emissions and After-Treatment Issues

In California, emissions related issues are a frequent cause of roadside breakdowns. Our emergency roadside assistance includes support for after-treatment and emissions system problems that can cause engine derates or shutdowns.

Roadside after-treatment support includes diagnostics related to DPF systems, DEF systems, sensors, and emissions fault codes. Addressing these issues promptly can help restore operation or determine the safest next step.
