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.
