Peterbilt Truck Repair in North Charleston, SC

Your Peterbilt’s electronics, powertrain, and aerodynamics work as an integrated system. Our shop’s OEM software directly links to SmartLINQ Technology for live fault codes, while our technicians interpret data from PACCAR Engines to identify root causes in minutes. From emissions and cooling to steering, brakes, and electrical systems, we adhere to factory specifications to ensure your warranty remains intact. Need a cosmetic refresh? We realign panels and bumpers to protect the truck’s Aerodynamic Design and chrome appeal. As a local Peterbilt repair shop, we blend precision repairs with clear communication so you leave knowing exactly what was fixed and why.

"I had a couple injectors go on my N14 Cummins and these guys changed the injectors and treated me an my driver very well and with respect the price was more than fair. I highly recommend this shop and their staff for any repairs that you may need."

Bob Wilson

"Very skilled, honest, and quick. Fixed my truck right the first time. Fair price and great service. I’ll definitely be back!"

Amg Boss

"I HIGHLY RECOMMEND THIS SHOP TO ANYONE IN THE AREA, NEEDING ANY REPAIRS DONE!!!!Every one of them were very polite, transparent, courteous, and respectful. My truck needed 2 new injectors, they ordered them IMMEDIATELY. Since the truck wasn’t going to be done that day, the one owner gave me a ride to the hotel, avoiding me from getting an uber. The next morning the other owner, out of his own pocket, got me an uber back to their shop. These guys are very knowledgeable in what they do!!"

Kevin Vivis

"My experience at General Diesel has been absolutely wonderful. The workers there show great customer service and the service on my vehicle was terrific. I recently brought my vehicle into the shop last Friday and ask for it back by Wednesday. I really wasn’t expecting for the vehicle to be serviced and complete, but General Diesel had the issue with the vehicle complete by Tuesday evening. Thank you General Diesel. I will definitely be coming back soon!"

Harris Borden

"I had a complex electrical fault in my Kenworth T680 truck. They did everything they could and finally detected the fault and repaired it. I would like to thank especially KENNY, who has years of experience in this business, and the owner of the business and the other employees. If you have a Kenworth truck, you should definitely go to GENERAL DIESEL, not a Kenworth dealer."
