Why Spotting the Signs Early Can Save You Thousands
Downtime isn’t just frustrating—it’s expensive. Whether you’re hauling freight across state lines or managing site logistics locally, a mechanical issue can sideline your operations and cost you in missed deadlines, lost revenue, and repair bills that pile up fast.
Fortunately, diesel trucks usually show signs of trouble long before they shut down. Recognizing the warning signs and calling a mobile diesel technician early can mean the difference between a quick roadside fix and a week-long repair in the shop.
At Matthews Motors, we’ve seen countless preventable breakdowns across Augusta and surrounding counties. Our certified technicians respond 24/7 to mobile service calls, catching issues before they become disasters. Here are five major red flags you should never ignore:
1. Unusual Exhaust Smoke or Sudden Power Loss
Notice black, blue, or white smoke trailing behind your rig? It’s not just cosmetic. or
- Black smoke: Often points to a rich fuel mixture or injector issues
- Blue smoke: Indicates burning oil
- White smoke: Suggests coolant leaks or a head gasket failure
Combine that with a loss of power or poor acceleration, and you’re one breakdown away from being stranded.
“Exhaust color tells a story,” says one Matthews Motors lead tech. “We can read it—and fix it—right on the roadside before it becomes a major repair.”
2. Dashboard Warning Lights (DEF & Check Engine)
Modern diesel engines are smart. That Check Engine light or DEF warning isn’t optional—it’s a cry for help.
If your Diesel Exhaust Fluid system or DPF regeneration process fails, your truck could enter limp mode or even shut down entirely.
Matthews Motors mobile units come equipped with full diagnostic scanners for Cummins, Duramax, Detroit Diesel, and other major engine systems—letting us pinpoint the problem without a shop visit.
3. Electrical Failures (Lights, Sensors, Starter)
Dash lights, malfunctioning sensors, or inconsistent starts are symptoms of:
- Battery failure
- Alternator trouble
- Corroded wires
- Faulty sensors
With mobile repair, there’s no need to tow your truck just to swap a sensor or replace a battery. We bring the solution to you.
4. Odd Noises or Vibrations
Clunking when you shift? Grinding when braking? Vibrations while accelerating? These could point to:
- Suspension issues
- Brake damage
- Drivetrain problems
Matthews Motors mobile techs are fully equipped to inspect and repair these issues on location—saving you both time and a tow.
5. Leaks, Steam, or Rapid Overheating
Coolant puddles, oil spots, or visible steam under the hood are signs of trouble. Don’t ignore:
- Coolant or oil leaks
- Blown hoses
- Overheating engines
Our mobile trucks carry hoses, clamps, fluids, and pressure testers to resolve these issues roadside—before a small leak turns into a full-blown engine failure.
