Common Semi Truck Issues & Specialized Services

Diagnostics and preventive maintenance are at the core of what we do. Many breakdowns start as small, avoidable issues, and catching them early keeps your truck out of the shop longer.

Common issues include: 

• Aftertreatment problems often show up as loss of power or repeated regens. These situations usually trace back to underlying faults that need proper testing, not guesswork.
• Cooling system trouble can creep up during long hauls or heavy loads. A weak fan clutch, failing water pump, or restricted radiator can quickly push engine temperatures too far.
• Electrical issues tend to be inconsistent, starting with intermittent faults and turning into no-starts or sensor failures. Pinpointing the exact cause requires detailed ECM data and system checks.
• Brake and suspension components wear gradually but impact safety right away. Worn S-cams, loose slack adjusters, or failing brake chambers can reduce control and need routine inspection.

FAQs

What are early signs of aftertreatment problems?

Frequent regens, reduced power, warning lights, or poor fuel economy can all point to aftertreatment issues. These systems rely on multiple sensors and components working together, so proper diagnostics are needed to find the root cause and prevent repeat failures.

How often should preventive maintenance be done?

Service intervals depend on usage, load, and driving conditions. Regular inspections help catch cooling issues, electrical faults, and wear on braking components before they lead to breakdowns. Staying consistent with maintenance reduces downtime and helps keep your truck in service longer.
