International Issues Recall on 600+ Trucks: What Drivers Need to Know

Truck_Drivers_USA — Thu, 11 Dec 2025 14:00:40 +0000

If you run an International, you may want to double-check your model year. The National Highway Traffic Safety Administration (NHTSA) has announced a new recall that affects more than 600 trucks currently on the road, and the issue could impact how your truck’s electronic control unit (ECU) responds to commands. For drivers, this recall isn’t just paperwork. It could affect how your truck behaves out on the highway.

Which International Trucks Are Impacted?

International Motors LLC has listed several popular models across a wide range of years. If you’re running one of these, it’s worth taking a closer look:

2016–2023 Lonestar
• 2018 8600
• 2018–2023 LT
• 2021–2026 MV
• 2022–2023 RH
• 2023–2026 HX
• 2025–2026 HV

The problem stems from electrical noise and low signal strength on the power line carrier. When that happens, the ECU may misread commands or stop working altogether, something no driver wants to happen mid-run.

What’s Causing the Issue?

The power line carrier isn’t consistently delivering a strong enough signal. That interference can confuse the ECU or interrupt it, leading to incorrect responses. Drivers may notice unusual behavior in systems tied to ECU communication, though the recall does not list specific alerts or warnings.

How International Plans to Fix It

International is teaming up with Bendix to reprogram the ECU software at no cost to owners. This fix will address the electrical noise and low signal issues that can cause the ECU to misread commands or stop working. Owner letters are expected to go out Jan. 19, 2026, and drivers can reach International customer service at 1-800-448-7825 with any questions. The recall number is 25525. Drivers can confirm whether their truck is included by searching VINs connected to this recall through NHTSA’s database. By completing this reprogramming, the company aims to ensure trucks operate safely and reliably, preventing ECU-related problems on the road.

International Motors

International is recalling certain 2023 through 2026 LT and RH models. The problem centers on the auto neutral function, which may not detect that the parking brake is engaged. If that happens, the transmission may fail to shift into neutral.
This recall affects 11,418 trucks.

Remedy
Dealers will replace the quick-release valve on the rear axle at no cost. Notification letters are scheduled to go out on January 19, 2026. Owners can reach International customer service at 1 800 448 7825. International lists this recall under number 25524. Vehicle Identification Numbers (VINs) involved are searchable here.

This follows an earlier November 25 recall that also involved LT and RH units.

Mack Trucks

Mack is recalling certain 2025 and 2026 Pioneer models due to load lock clamps on the back of the cab that can loosen and cause the load lock bars to become unsecured.

This recall impacts 247 units.

Remedy
As an interim fix, Mack will push a software update over the air to disable the AHB. The final repair is still being developed. Interim letters are expected January 17, 2026, with additional notices once the full solution is ready. Owners may contact the same Mack customer service line. Mack lists this recall under number SC0488. Vehicle Identification Numbers (VINs) involved are searchable here.
