Freedom Diesel Mobile

When your diesel truck or generator breaks down, do you really want to spend a whole day driving to a shop in Los Angeles, CA? Freedom Diesel Mobile provides expert diesel repair right where you are, so you can get back to work faster with less downtime and greater confidence in the fix.

Built On Experience, Powered By Accountability

Freedom Diesel Mobile was founded in 2024 by Tito Isais and became fully operational in 2025 with a clear mission: deliver dealership-level repairs with mobile convenience and straightforward answers. Tito didn’t stumble into diesel—he trained for it. He attended school to become a diesel technician, gained real-world experience in dealership settings (including running a shop), and ultimately found his stride as a mobile technician, where every call demands critical thinking, adaptability, and the ability to diagnose under real job-site conditions.

That mobile challenge is exactly what shaped this business. Over the years, Tito also helped other technicians improve their skills, including his time as a trade tech school instructor. Today, he applies that same methodical approach—measure twice, fix once—to every service call.

What We Do: Mobile Diesel, Diagnostics, Brakes, Generators, & More

We’re a mobile-only diesel repair service that focuses on keeping commercial vehicles reliable and compliant. Our main services include:

• Diesel engine repair and troubleshooting
• Electrical and diagnostic repairs (including complex drivability and fault-code issues)
• Brake repairs and inspections
• Generator service and repair for diesel-powered units

We also perform alignment work when it is suitable for mobile service. Since we’re not in a fixed bay with full alignment racks, we concentrate on front-axle alignments where mobile adjustments are practical and effective.

Certifications That Matter

Repairs are only as effective as the technician behind them. Tito is ASE-certified and has specialized training in aftertreatment systems. He’s also certified in Clean Air Truck Testing, which means he understands the emissions side of modern diesel repairs — not just swapping parts but identifying root causes that trigger derates, warning lights, and repeated failures.

Transparency First, Quality Always

At Freedom Diesel Mobile, transparency isn’t just a slogan — it’s our way of working. You’ll always know what you’re paying for upfront, what the diagnosis revealed, and which options fit your truck, budget, and schedule. Tito’s work ethic is straightforward: get the job done right the first time, using proven methods and clear communication from start to finish.
