Mobile diesel mechanic and truck repair in DeBary, FL

DeBary is the first Volusia stop after I-4 and US 17-92 cross the St. Johns River. When a diesel quits here, an RDI Power technician comes out from our Brooksville shop with diagnostic tools and on-site repair capability.

A pair of bridges brings traffic into DeBary from Seminole County. I-4 crosses the St. Johns River at the mouth of Lake Monroe on a 6-lane, 2-span bridge finished in 2004, and US 17-92 comes over from Sanford on the Bill Benedict Bridge, which replaced the 1933 Lake Monroe Bridge in 1994. RDI Power has no shop or office in DeBary. Our technicians travel out from Brooksville to fleet yards, job sites and roadside stops in the city, and the first phone call is where we sort out whether the truck can be repaired where it sits.

Stopped on I-4 or US 17-92 in DeBary

FDOT’s 2025 traffic inventory counts roughly 10,912 trucks a day on I-4 near DeBary, about 7.5% of everything on that stretch. US 17 between Saxon Boulevard and Enterprise Road carries far less traffic overall, yet trucks make up 21% of it, around 4,725 a day. Those 2 roads call for different handling when something fails.

On the interstate, a shoulder beside more than 145,000 vehicles a day is a poor place for a long repair. If the truck can still roll, the next exit or a wide, level spot well clear of the lanes gives the technician room to work. On 17-92, a side street or a lot beside the corridor beats the curb lane. Either way, the technician makes the final call on whether a spot is safe before any tools come out.

Pinpointing a truck in DeBary for the technician

Clear directions matter more when the service truck is coming across the state. Give us:

  • The road and direction of travel, and on I-4, the last exit you passed and whether you have crossed the river yet
  • The nearest cross street on 17-92, such as Saxon Boulevard or Enterprise Road
  • A landmark if one is close, such as the DeBary SunRail station
  • Year, make, engine and unit number, plus any warning lights or dash messages
  • Whether the truck is loaded and whether someone is staying with it

Repairs that can finish on site in DeBary

Plenty of strandings come down to a short list of failures, and a service truck carries what it takes to handle many of them. Before anything is replaced, the technician connects and reads codes and live data: Ford IDS on a Power Stroke, WiTECH on a Ram, heavy-duty software on a tractor. Then the repair:

  • No-crank and slow-crank problems traced to batteries, cables, grounds or the starter
  • Charging faults and alternator replacement
  • Air leaks, brake chambers and slack adjusters on air-brake trucks
  • Fuel filter and water separator service, and purging air after a filter change
  • Failed sensors and wiring behind a derate or a shutdown
  • Belts, hoses and coolant leaks the technician can reach

Each job is written up on a digital vehicle inspection with photos and the technician’s notes, so whoever pays for the repair can see what failed and what was replaced.

Job sites around DeBary’s power plant and solar farm

DeBary is more than commuters and SunRail riders. The city holds a 10-unit combustion turbine plant that runs mainly during peak demand, Duke Energy’s 74.5 MW solar farm, online since May 2020, and Konomac Lake, a Florida Power & Light reservoir. Team Volusia also lists Smart Baking as a DeBary manufacturer. If your crew’s trucks work sites like these, the technician comes to the site rather than the truck coming off the job. Have the gate instructions and a site contact ready, and park the truck on firm, level ground if it can still move.

When a DeBary breakdown needs the Brooksville bays

Some failures should not be fixed on a shoulder: internal engine damage, a failed transmission, or anything that needs a lift and heavy tooling. When the diagnosis points there, we lay out the options with you, including how and when the truck makes the trip to Brooksville and what the schedule looks like while it is down. Because the fault was confirmed on site, the shop starts from a known failure instead of from scratch. Labor carries RDI Power’s 3-year / 36,000-mile warranty, or the 2-year / 24,000-mile fleet warranty on RDI Fleet accounts.

Who to call from DeBary, and when

Fleet customers have 24/7 roadside assistance. Everyone else can reach the shop at (352) 433-3800 on weekdays from 7:00 AM to 4:00 PM. You will get a straight estimate of when a technician can be there, based on where the truck sits and what is already on the board, never a promised arrival time. Operators who would rather see fewer roadside calls can read how planned work is set up on our DeBary fleet maintenance page, and the full on-site program is on mobile diesel repair. Trucks that stop on the Seminole side of the river are covered on our Sanford mobile diesel repair page.

DeBary questions

What should I do if my truck stops on I-4 just past the Lake Monroe bridge into DeBary?
Get it as far from the travel lanes as it will go, turn on the hazards and set out your warning devices. Then call with your direction and the last exit you passed; the technician decides on arrival whether that spot is safe to work or the truck has to be moved first.
Does RDI Power have a shop or office in DeBary?
No. The only RDI Power shop is in Brooksville. In DeBary we work on-site at yards, job sites and the roadside, and heavier repairs are planned into the Brooksville bays.
Will 24/7 roadside cover my pickup if it dies on US 17-92 in DeBary on a Sunday?
Round-the-clock roadside is part of an RDI Fleet account. Without one, call (352) 433-3800 on a weekday between 7:00 AM and 4:00 PM.
