Mobile on-site serviceRoadside & yard repairQuoted before work begins
Diesel trucks. Real problems.
Repair starts at the truck.
Call about semi trucks, commercial diesel trucks, and diesel pickups. We match the job to the available mechanic and confirm which work can be handled at your location. A useful first call gets the vehicle, symptoms, and service address clear before anyone travels.
Cooling & coolant leaks
Report rising temperature, coolant loss, steam, or a damaged hose. Mobile work can include accessible cooling-system diagnosis and repairs when the vehicle and work area are suitable.
Air & brake concerns
Tell dispatch about low-air warnings, audible leaks, pressure that will not build, or a brake problem. We confirm the repair scope and whether the truck can be worked on safely.
Fuel & engine diagnosis
Hard starting, stalling, loss of power, and warning lights can have several causes. Share the engine, symptoms, and any fault codes so dispatch can check the mechanic and equipment needed.
For symptoms to mention on the call, see our diesel no-start guide or overheating and coolant-loss guide.
Local coverage
Knoxville
and 50 miles around it.
Knoxville connects major truck routes on I-40 and I-75. A roadside breakdown, a truck that will not start at a yard, or an air or cooling concern can interrupt the whole run. We take mobile diesel repair requests within 50 miles of Knoxville, including nearby East Tennessee communities such as Farragut, Maryville, Oak Ridge, and Clinton.
Our service area is a 50-mile radius around Knoxville. The exact service address, road access, mechanic availability, and repair scope determine whether dispatch can accept the job.

Give dispatch a clear starting point.
On I-40 or I-75 around Knoxville, give the highway, direction of travel, and nearest exit or mile marker. These routes share part of the corridor, so a location pin helps dispatch identify the right approach. For a truck near Lenoir City, Sevierville, or the edge of the service area, the exact address also helps confirm access and travel before a mechanic is assigned.
If the truck is at a customer yard or terminal, share gate instructions, a site contact, and whether there is safe space to work. For fleet vehicles, have the unit number and the person who can authorize work available. If you are calling for a driver, confirm the truck's location rather than your own office address.
Some jobs require a shop, towing, specialized equipment, or parts that are not available immediately. Dispatch will discuss those limits before arranging a visit. We do not promise an arrival time until current coverage and the job have been checked.
Before you call
A few useful answers.
Can you come to my truck today?
Call with your exact location and repair need. Dispatch checks the mechanic currently available for Knoxville and the surrounding 50-mile area. Availability and timing are confirmed on the call; submitting a request or seeing an ad does not reserve a mechanic.
What will the repair cost?
The vehicle, diagnosis, travel, parts, and repair scope affect the price. Ask dispatch about the applicable service and diagnostic charges. The repair plan and pricing are discussed before work begins, and additional work requires approval.
Do you have a shop I can drive to?
This page describes mobile service coverage. Call to arrange service at your truck's location. It does not represent a walk-in repair shop in Knoxville.
What if the truck cannot be repaired on site?
We will explain the limits of the mobile repair and the next step. Major teardown, an unsafe work location, or a need for shop equipment may mean a tow or shop visit is the better option.
