Top 3 Truck Repair Services and Diesel Shops in Nashville, TN

Selecting a commercial truck repair vendor in Middle Tennessee is a different exercise than choosing a pickup mechanic. Class 7 and Class 8 tractors, vocational straight trucks, and the trailers behind them sit under Federal Motor Carrier Safety Administration (FMCSA) jurisdiction, which means every unit must clear a 49 CFR 396.17 annual inspection, carry the corresponding inspection report or decal, and present documented maintenance records on demand. Engine families (Cummins X15, PACCAR MX-13, Detroit DD15, International A26, Volvo D13) each carry distinct diagnostic platforms, factory training requirements, and warranty pathways, and aftertreatment work on diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems requires EPA tampering-rule literacy that strip-mall auto shops rarely possess. The three operators profiled below run franchised OEM dealer service departments in the Nashville metropolitan area, each pairing factory-trained diesel technicians with the parts inventory, alignment racks, and chassis dynamometers a heavy-truck fleet manager actually needs.

Each profile covers founding history, brand authorizations, the service menu (preventive maintenance A/B/C, DOT inspection, engine, drivetrain, brake, body), and the in-house capability that separates the dealer from a generic diesel garage. The three operators were chosen for documented OEM franchise status, multi-decade trade presence, and a service mix that spans medium-duty straight trucks through Class 8 over-the-road tractors rather than a single equipment niche.

1. Cumberland International Trucks: Nashville-Headquartered International Dealer #

Cumberland International Trucks, headquartered at 640 Massman Drive in Nashville, has held the International Truck franchise for Middle Tennessee since 2005, with sister branches in Murfreesboro, Lebanon, and a Florida corridor running from Jacksonville through Orlando, Ocala, Daytona, and Palm Bay. The Nashville facility serves as the flagship shop and houses an in-house alignment rack capable of squaring full Class 8 tractor chassis, an investment few independent diesel garages can justify. The dealership is the authorized service point for International medium-duty MV Series and HV Series trucks, the heavy-duty LT Series and RH Series tractors, IC Bus school and commercial bus chassis, and Capacity yard spotter tractors, with parts and labor coverage for Cummins B6.7, L9, and X15 engines installed in those platforms.

Mobile Diesel and Emergency Roadside #

The shop runs a 24-7 mobile diesel division dispatched on (615) 256-4633, equipped to handle roadside diagnostics, jump-starts, fuel-system priming, air-system leaks, DPF face-cleaning under regen-stuck conditions, and engine fault-code clears for fleets that cannot deadhead a tractor back to Massman Drive. The mobile trucks carry OEM parts pulled from the Nashville parts counter, which keeps a stocked inventory of International filtration, brake shoes, slack adjusters, and aftertreatment sensors so that a roadside call rarely escalates into a multi-day parts-order delay. Service-bay capability covers DOT 49 CFR 396.17 annual inspection, preventive maintenance A/B/C tiers, complete engine rebuilds, transmission and differential overhauls, trailer brake and ABS work, and warranty repairs across the International and IC Bus product lines.

Hours and Dispatch #

The Nashville parts and service counter operates Monday through Friday from 7 a.m. to midnight and Saturday from 7 a.m. to 3:30 p.m., a longer service window than most regional dealers maintain. The main switchboard is (615) 829-7800, the service desk is (615) 829-7900, and the parts counter is (615) 829-7860, with separate dispatch lines for warranty, mobile, and Idealease lease-rental customers operating the same chassis under lease contract.

2. MHC Kenworth Nashville: 24-Hour PACCAR and All-Makes Shop #

MHC Kenworth Nashville, located at 550 Spence Lane, is the Middle Tennessee branch of Murphy-Hoffman Company, a Kenworth dealer group founded in 1975 in Springfield, Missouri by Reed Murphy Senior and Ken Hoffman and now headquartered in Leawood, Kansas with 130-plus locations across 19 states. The parent group has earned Kenworth North American Dealer of the Year recognition on multiple occasions across the last three decades, and the Nashville store carries the same factory-training pipeline, parts allocation, and warranty authority as the flagship locations in Kansas City and Dallas. The shop runs 24 hours a day, seven days a week, which matters for over-the-road fleets that route their tractors through Nashville on the I-40 and I-65 corridors and need a service door open at 2 a.m.

PACCAR, Cummins, CAT, and Eaton Certifications #

The service department holds PACCAR MX-11 and MX-13 engine certification, Cummins ISX and X15 engine certification, Caterpillar legacy C13 and C15 certification for the pre-2010 chassis still rolling in vocational fleets, and Eaton transmission and clutch certification covering the Fuller manual, UltraShift Plus automated manual, and Endurant heavy-duty AMT product lines. The shop is an all-makes service center, meaning the technicians work on Peterbilt, Freightliner, Volvo, Mack, International, and Western Star equipment in addition to the Kenworth nameplate, with the parts counter stocking the TRP all-makes line alongside genuine PACCAR parts. DPF two-stage cleaning, mandatory at fleet-specified intervals for emissions compliance, runs on a dedicated bake-and-blow oven on site.

Body Shop, CNG, and Rental #

A full all-makes body shop handles cab repair, paint, frame straightening, and post-accident rebuilds, and the shop carries compressed natural gas (CNG) service certification for the Cummins Westport ISX12N and L9N engine families running in regional delivery and refuse fleets. Short- and long-term truck rental, full-service Paclease leasing, and a drivers lounge with WiFi round out the on-site offering. The local switchboard is (615) 366-5454, the toll-free line is (866) 728-7740, and the fax for purchase orders and lease paperwork is (615) 366-2539.

3. Rush Truck Centers Nashville: Peterbilt and Multi-Brand Medium-Duty #

Rush Truck Centers Nashville, with its primary facility at 900 Expo Drive in Smyrna and a central location at 727 Fesslers Lane in Nashville, is the Middle Tennessee branch of Rush Enterprises, a publicly traded dealer group W. Marvin Rush founded in Houston in 1965 and listed on NASDAQ under ticker RUSHA in 1996. The parent company holds the largest network of Peterbilt dealerships in North America, picked up its first Peterbilt franchise in 1967, and added medium-duty Hino, Isuzu, and Ford franchises across 2003 to 2005 to round out the Class 4 through Class 7 product line. Rush Enterprises today runs more than 200 dealership and affiliate locations across North America with annual revenue above 7.8 billion dollars.

Xpress Service and 86-Point B-Inspection #

The Smyrna shop runs the Rush Xpress Service program, which guarantees same-day diagnostics and repair estimates on preventive maintenance, brake, lighting, and minor electrical work routed through a dedicated drive-through bay. The branded preventive maintenance ladder runs an A Service oil and filter package, a B Service 86-point inspection that bundles DOT 49 CFR 396.17 annual inspection, water filter replacement, cooling-system pressure test, and coolant chemistry test, and a C Service heavy interval covering driveline lubrication, differential service, and air-dryer rebuild. The shop runs an on-site collision center for post-accident cab and frame repair across all makes, paired with a paint booth sized for Class 8 sleeper cabs.

Mobile Service and Engine Overhaul #

Rush operates a mobile service fleet dispatched from the Smyrna yard, equipped to bring diagnostic laptops, brake tooling, aftertreatment sensor inventory, and electrical repair capacity to fleet yards across the Nashville, Murfreesboro, and Lebanon corridors. The shop holds PACCAR PX-7 and PX-9 medium-duty certification and full PACCAR MX-11 and MX-13 heavy-duty certification, with engine overhaul capability spanning short-block replacement, in-frame rebuild, and complete remanufactured-engine swap on Peterbilt and all-makes equipment. The Smyrna dispatch line is (615) 220-7600, and the Central Nashville location on Fesslers Lane runs through (629) 295-8035.

Selection Methodology #

The three operators above were selected from the broader Nashville commercial truck repair field using these filters: minimum tenure on Nashville-area heavy-duty service, verifiable OEM franchise authorization on file, brand-name anchor with verifiable address visible on the operator’s own website, and a published service scope that maps to fleet maintenance need without scope-of-practice overreach. Independent diesel garages without OEM franchise authority, single-equipment niche shops, and offices without verifiable street addresses were excluded.

Frequently Asked Questions #

Q: How do I verify a Nashville commercial truck repair operator holds the right credentials?
A: Use the Federal Motor Carrier Safety Administration Safety and Fitness Electronic Records system at safer.fmcsa.dot.gov for the carrier customer side, the Tennessee Department of Revenue Motor Carrier Services unit for IRP and IFTA standing, and the OEM (International, Kenworth/PACCAR, Peterbilt) dealer locator for franchise authorization.

Q: What sets these three apart from the broader Nashville commercial truck repair field?
A: Each operator carries verifiable Nashville tenure, OEM-authorized factory training on the engine and chassis families they service, a brand-name anchor with a working street address, and a published service scope that does not bundle unrelated repair categories.

Q: Are any of the three operators paid placements?
A: No. The three profiles above are editorial selections drawn from publicly verifiable sources. No operator sponsored placement.

Q: How should I prepare for a first service visit?
A: Confirm your fleet account terms with the dealer service desk, bring the unit’s title, registration, current 49 CFR 396.17 annual inspection report, and any open warranty claim numbers, and request the dealer’s published preventive maintenance ladder (A/B/C tiers) in advance to align expectations on the first repair order.
