Diesel Service

Truck & Fleet Repair

Pickups to semis and the trailers behind them — diagnosed and repaired by experienced techs in a fully equipped Austin shop.

Commercial truck & fleet repair, done right

Modern Diesel’s technicians work out of a fully equipped, state-of-the-art facility built to handle everything from routine fleet maintenance to complex heavy-duty repairs. Our team is trained across the systems that matter — engine and drivetrain diagnostics, air conditioning, brakes and suspension, exhaust and emissions, welding, and more — so every job is done to industry best practice.

What we service

  • Heavy-, medium-, and light-duty diesel trucks
  • Trailers — brakes, lights, suspension, and structure
  • Vans, pickups, and mixed commercial fleets

A maintenance plan built around your fleet

A Fleet Service Plan matches managed maintenance to how your vehicles actually get used and to your budget. It pulls together preventative maintenance, safety inspections, and repairs — and for business customers, on-site fleet diagnostics and repairs at your location — so your fleet stays safe, compliant, and earning instead of sitting.

Warranty coverage is set with your service advisor at the time of service.

Why Modern Diesel

Established in 2015, we’ve grown into a trusted fleet partner across the Greater Austin Area (Travis, Bastrop, Williamson, Hays) by sticking to three things: professionalism, quality workmanship, and proactive maintenance. We’re a Christian, veteran-owned shop — teamwork, training, and current technology on every job.
