From Jedburg Rd to College Park Rd

Jedburg Rd (Exit 194)

The Jedburg industrial area holds a logistics park with a large cross-dock building and last-mile delivery hubs, and the truck stop at the exit has truck parking. We come to units parked at any of them.

Nexton Pkwy (Exit 197)

Nexton Pkwy runs from I-26 to US-176, serving Nexton (in Berkeley County), Carnes Crossroads, and Cane Bay. Warehouses in the Charleston Trade Center sit right off the interchange.

US-17A (Exit 199)

Exit 199A takes US-17A south into Summerville as Main St, and 199B heads north toward Moncks Corner. We work on contractor trucks, service vans, and diesel pickups at shops and jobsites along it.

Ladson & Dorchester Rd

Ladson Rd runs through the Oakbrook area of Summerville, connects to Palmetto Commerce Pkwy, and forms a corridor with US-78 (Exit 205). College Park Rd (Exit 203) serves Ladson, and Dorchester Rd (SC-642) runs on into North Charleston. The Dorchester Commerce Center on Hodge Rd sits just off I-26.

Summerville is spread out. The truck should not have to move.

Summerville sits mostly in Dorchester County, with pieces in Berkeley and Charleston counties, and its truck traffic is split across a string of I-26 exits. Hauling a disabled truck from a Jedburg Rd dock or a Nexton jobsite to a shop can cost a day before anyone opens the hood. We do all of our work on-site, so the testing starts where the truck stopped.

Lowcountry Diagnostics is based in Goose Creek and covers Summerville 24/7. Founder and lead diesel technician Joseph Cufaude brings 13 years in the diesel trade to no-starts, derates, air brake problems, and DPF cleaning, and every call ends with written findings and a clear next step.

What a Summerville service call looks like

1. Tell us the exit or jobsite

An exit number such as 194, 197, or 199, a Main St address, or a jobsite in Nexton or Cane Bay gets us to the truck. Add the make and what it is doing.

2. We test where it sits

At the dock, on the jobsite, or on the shoulder, we confirm the failed part with codes, live data, and system tests before replacing anything.

3. Fix it or plan it

Practical repairs happen on the spot. If the truck needs more, you get a written plan and decide what comes next.
