ABOUT Stellar Mechanic

Fleet Maintenance Built From Experience
Stellar Mechanic was created after we experienced firsthand how difficult it could be to find dependable, accessible maintenance for commercial delivery vehicles. When a local mechanic closed his shop and our own fleet still needed reliable service, we recognized an opportunity to build something better.
What began as a solution for our own vehicles grew into a fleet-service company designed around the specialized needs of FedEx contractors, BCs, and private fleet owners.
Today, Stellar Mechanic provides fleet maintenance and support at the FedEx terminals in San Diego and Bakersfield. We understand that every vehicle represents revenue, responsibility, and a commitment to your customers. Our goal is to reduce downtime, identify maintenance concerns early, and help keep every vehicle safe, compliant, and ready for its route.
We Understand Fleet OperationsFleet maintenance involves more than repairing a vehicle when something goes wrong. It requires preventive planning, clear communication, accurate inspections, dependable scheduling, and an understanding of how vehicle downtime affects the entire operation.
Our services include preventive maintenance, brake service, fleet inspections, tire service, diagnostics, VEDR and camera installation, anti-theft equipment installation, safety-equipment installation, and vehicle decal placement.
Whether you manage a few delivery vehicles or an entire fleet, Stellar Mechanic provides practical service tailored to the demands of your operation.
Our CommitmentWe are committed to providing:

• Honest and straightforward communication
• Dependable workmanship
• Clear inspection and repair recommendations
• Service built around fleet schedules
• Long-term support for contractors and fleet owners

At Stellar Mechanic, we do not simply work on vehicles—we help protect the equipment your business depends on.
