2021-2025 International Truck Recall 24V818: ECU Signal

RN
Reviewed by the RecallNotify editorial team
Published May 20, 2026

Recall 24V818 affects 105,276 2021-2025 International trucks for Bendix ECU command-processing failures. Repair is free at any franchised International dealer.

International is recalling 105,276 2021-2025 Mv, Hx, Hv, Rh, Lt, Lonestar, and Prostar vehicles because electrical noise or a weak power line carrier signal can make the Bendix EC80 Advanced ECU process commands incorrectly or stop working. Safety systems tied to that ECU can lose or have reduced function, including ABS, stability control, active cruise control, and collision mitigation, increasing crash risk; International dealers will complete the recall repair free of charge.

What's wrong?

The EC80 Advanced Electronic Control Unit is the brake system computer on affected 2021-2025 International trucks. It manages the air brake antilock system, automatic traction control, and electronic stability functions when equipped. On trucks pulling air braked trailers, it also communicates trailer brake information over the power line carrier network, which sends signals through the trailer electrical connection.

On affected trucks, electrical noise and a low signal on that power line carrier connection interfere with the ECU's software logic. The ECU can incorrectly process commands, set a fault, stop operating, or malfunction. That means the system that helps manage antilock braking and stability support is not processing trailer-related signals as designed.

The warning sign is an illuminated ABS warning lamp. That light turns on when the system detects an ABS fault or when the ABS stops operating.

Field incidentsNHTSA has logged no field incidents to date.

The year, model, and truck line narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

When ECU-dependent systems lose functionality, Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collision Mitigation System protection is reduced, increasing crash risk. If the ABS warning lamp illuminates, treat it as a fault signal and schedule service promptly. Repair is free at any franchised International dealer.

What should I do?

  1. Check your VIN to confirm your 2021-2025 International Mv, Hx, Hv, Rh, Lt, Lonestar, or Prostar vehicle is included in this recall.
  2. Contact a franchised International dealer to schedule the free Bendix EC80 ECU software reprogramming that fixes the brake and stability-system control issue.
  3. Bring the recall notice if International mailed one. If not, reference recall number 24V818 when you call.
  4. Call International customer service at 1-800-448-7825 with questions before your dealer visit.
  5. Drive cautiously until the software update is complete. Leave extra following distance and avoid relying on affected driver-assistance systems.

What happens at the repair

At the dealer, an International technician coordinates with Bendix to reprogram the Bendix EC80 Advanced ECU software. The software update is free under recall 24V818, with parts and labor covered.
