Owners of affected vehicles will be notified by mail beginning in October, and all repairs will be completed at no cost through authorized dealerships.

Volvo Recalls More Than 1,800 Trucks

Volvo Trucks North America is recalling 1,851 model-year 2027 VNL and VNR trucks because the center roof marker lights may fail to illuminate.

According to NHTSA, the issue means the affected trucks may not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 108, which establishes requirements for vehicle lighting and reflective equipment. Marker lights help improve a commercial vehicle’s visibility to other motorists, particularly during nighttime and low-light conditions.

Volvo dealers will replace the center roof marker light assembly free of charge.

Owner notification letters are expected to be mailed on October 5, 2026. Drivers or fleet owners with questions can contact Volvo Trucks customer service at 800-528-6586 and reference recall number RVXX2608. Affected Vehicle Identification Numbers (VINs) can also be searched through NHTSA’s online recall database.

Mack Issues Similar Recall for Anthem and Pioneer Models

Mack Trucks has announced a similar recall covering 513 model-year 2027 Anthem AN and Pioneer PR trucks.

Like the Volvo recall, the center roof marker lights may fail to illuminate, creating a potential noncompliance with FMVSS No. 108.

Dealers will replace the affected marker light assembly at no charge, and owner notification letters are also expected to be mailed on October 5, 2026.

Owners can contact Mack customer service at 800-866-1177 and reference recall number SC0498. VINs included in the recall can be verified through NHTSA.

International Recalls Trucks Over Windshield Wiper Issue

International Motors is recalling 49 model-year 2027 HV, HX, LT, MV, and RH trucks because a retaining nut within the windshield wiper assembly may loosen over time.

If the retaining nut loosens, both windshield wipers can disconnect from the motor, reducing visibility during rain or other adverse weather conditions.

To correct the issue, dealers will tighten the wiper motor drive nut along with three motor mounting bolts at no cost to vehicle owners.

Owner notification letters are expected to be mailed on October 5, 2026. International customers can contact the manufacturer’s customer service department at 331-332-5000 and reference recall number 26513.

How Drivers Can Check if Their Truck Is Included

Drivers and fleet managers can determine whether a specific vehicle is included in any active recall by entering the truck’s VIN into NHTSA’s online recall lookup tool. Even if a truck appears to be operating normally, manufacturers recommend having recall repairs completed as soon as parts and dealer appointments become available.

Although manufacturers operate additional facilities for engines, components, and specialty vehicles, the following plants are among the largest and most important final assembly locations for Class 8 trucks in North America.

Cleveland, North Carolina

Freightliner’s Cleveland Truck Manufacturing Plant has become one of the busiest heavy-duty truck assembly facilities in North America. Operated by Daimler Truck North America, the plant is best known for building the Freightliner Cascadia, a model that has led the North American Class 8 market for years.

The facility has expanded multiple times since opening, reflecting continued demand for Freightliner highway tractors. In addition to final assembly, Cleveland serves as a key production center within Daimler’s broader North American manufacturing network.

Dublin, Virginia

Volvo Trucks builds nearly all of its North American highway models at the New River Valley Plant in Dublin, Virginia.

The plant opened in 1975 and has grown into Volvo’s largest truck manufacturing facility worldwide. Today it assembles the VNL, VNR, VNX, and VHD while incorporating advanced robotics, automated material handling systems, and modern quality control processes throughout production.

Denton, Texas

Peterbilt’s Denton manufacturing plant has been the company’s primary assembly location since the early 1980s.

The facility produces both highway and vocational trucks, including the Model 579, one of Peterbilt’s best-known long-haul tractors. Denton also houses engineering, testing, and administrative operations, making it one of the company’s most important campuses.

Chillicothe, Ohio

Kenworth’s Chillicothe Assembly Plant remains one of PACCAR’s largest truck manufacturing facilities.

The plant assembles a range of on-highway and vocational models while using robotic welding systems, automated paint operations, and extensive inspection procedures. Continuous upgrades over the years have helped the facility keep pace with changing production demands and manufacturing technology.

Macungie, Pennsylvania

Mack Trucks has built commercial vehicles in Pennsylvania for generations, and its Lehigh Valley Operations facility in Macungie continues that tradition today.

The plant assembles the Anthem, Granite, Pinnacle, LR, MD, and TerraPro model lines for customers across North America. While Mack’s products have evolved considerably, the company’s long manufacturing history remains closely tied to Pennsylvania.

More Than an Assembly Line

A finished truck represents the work of far more than a single factory.

Before reaching final assembly, engines, transmissions, axles, wiring harnesses, braking systems, electronics, interiors, and other major components are produced at facilities throughout North America. Final assembly plants bring those components together before each truck undergoes inspection, testing, and quality verification.

Although the names on the hood differ, every manufacturer follows the same basic goal: producing trucks that can withstand hundreds of thousands of miles in demanding commercial service.

Frequently Asked Questions

Why are so many truck manufacturing plants located in the southern United States?

Many manufacturers expanded into the South because of available land, transportation access, established supplier networks, and a skilled manufacturing workforce. Proximity to major interstate highways and distribution routes also supports efficient delivery throughout North America.

Are heavy-duty trucks built only in the United States?

No. Heavy-duty truck manufacturing takes place in both the United States and Mexico. Modern production relies on facilities in both countries, with components moving across borders before final assembly.

Do manufacturers build every part of a semi truck themselves?

No. Most heavy-duty trucks contain components supplied by hundreds of specialized manufacturers. Assembly plants receive those parts before completing final assembly and inspection.

Which truck plant has been operating the longest?

Several facilities have decades of manufacturing history. Volvo’s New River Valley Plant opened in 1975, while Mack has maintained truck manufacturing operations in Pennsylvania for well over a century through various facilities.

How many trucks can a modern assembly plant build?

Production varies by manufacturer, staffing levels, demand, and model mix. Large heavy-duty truck plants are capable of producing hundreds of trucks during a typical production week.

PACCAR Recall

PACCAR is recalling some 2026 Peterbilt 567 and 589 trucks because the air tanks don’t hold enough air for the brakes. That means these trucks don’t meet the federal safety standard for air brakes. Only 62 trucks are affected, but if you drive one of them, it’s important to get it fixed.

Dealers will replace the tanks with the right ones at no cost. Letters to owners are expected to go out on January 16, 2026. You can also call Peterbilt customer service at 1-940-591-4220. The PACCAR recall number is 25PACH.

International Recall

International is recalling certain 2023-2026 LT trucks and 2024-2025 RH trucks. The problem is with the Hill Start Assist system. If the exhaust port gets clogged, it could delay or stop the service brakes from releasing, which is dangerous.

This recall covers 1,303 trucks. Dealers will relocate the HSA valve exhaust free of charge. Letters were mailed on January 12, 2026. For questions, call International at 1-800-448-7825. The recall number is 25522.

What This Means for Drivers

If you drive one of these trucks, check your VIN and set up a repair appointment as soon as possible. Both PACCAR and International are handling the repairs at no cost, but waiting could put you and your load at risk. Staying on top of recalls keeps you safe on the road and helps make sure your deliveries stay on schedule.

This collaboration between Allison Transmission and International Truck introduces the Allison 3414 Regional Haul Series (RHS) for ordering in International RH trucks equipped with the S13 engine. The Allison 4000 Series is also now orderable in S13-equipped International HX trucks.

With the launch of the S13 engine, Navistar recognized the demand for diverse powertrain options. To that end, it has responded by integrating Allison’s fully automatic transmissions into International’s RH and HX platforms.

Allison said that this combination, alongside the Navistar S13 engine, provides customers with two high-performance solutions boasting superior acceleration and optimized efficiency.

“We are proud to collaborate with International Truck to pair both the 3414 RHS and 4000 Series fully automatic transmissions with the Navistar S13 engine for an industry-leading driving experience,” said Rohan Barua, Vice President, North America Sales, Global Channel and Aftermarket at Allison Transmission. “Specifically, the 3414 RHS fully automatic transmission offers increased horsepower and a lighter weight, translating into more deliveries, more loads, and more productivity.”

Since its introduction with the Navistar A26 engine in 2020, 3414 RHS-equipped International RH trucks have garnered interest from major fleets across North America, including prominent wholesale food distributors. The transmission has also seen uptake among regional food and beverage distribution fleets.

The 3414 RHS is tailored to enhance vehicle handling and maneuverability in urban duty cycles, delivering superior performance and efficiency. Compared to the Allison 3000 Highway Series transmission, it improves fuel economy by up to 8%. Additionally, it eliminates downtime typically associated with automated manual transmissions (AMTs) by circumventing the need for clutch replacements.
