Fred Johnson Diesel Service LLC/MOBILE ROADSIDE DIESEL REPAIR

Fred Johnson Diesel Service LLC operates as a mobile roadside diesel repair provider serving the Memphis, Tennessee metro area and surrounding corridors. With a 4.8-star rating compiled from 45 customer reviews, the business has established a solid reputation among commercial truck operators, independent owner-drivers, and transport companies requiring emergency diagnostics and repairs away from a fixed shop location. The service model centers on bringing tools, parts, and expertise directly to disabled or malfunctioning diesel vehicles, eliminating the need for costly towing operations.

What distinguishes this mobile repair operation is the willingness to diagnose issues on-site at no charge, a practice highlighted by multiple reviewers who describe encountering Fred while he was working on another customer's truck. This diagnostic-first approach allows truck operators to understand the scope of needed repairs before committing to a full service call. The business handles common roadside failures including cooling system repairs, brake maintenance, and general diesel engine troubleshooting.

Customer stories reveal consistent themes of responsive service during stressful breakdowns. One reviewer recounts a radiator hose failure on a highway ramp where Fred tracked down a replacement hose, worm clamps, and coolant, completing the repair in short order. Another describes Fred arriving during a brake failure on I-40 through Memphis to provide immediate assistance. The technician maintains a transparent communication style, explaining what repairs are needed and why, without attempting to inflate repair costs.
