Volvo VN and VAH trucks lose electronic safety systems

NHTSA campaign 24V790000 · Reported 2024-10-23 · Volvo Trucks North America

high How serious is it? About this label

Serious, because braking and stability aids you count on may quietly stop working; the notice does not tell drivers to park the truck, so it can stay in service until the free reprogramming is done.

What's wrong, in plain English

These trucks have a control unit that runs several driver-assist and braking systems. Electrical interference and a weak signal can make that unit misread commands or quit working. When it does, anti-lock brakes, traction control, stability control, adaptive cruise control, and the collision warning system can work poorly or stop working at all. A dealer fixes this by loading new software into the control unit, which does not require replacing parts.

What you should do

1. Enter the truck's VIN at nhtsa.gov/recalls to confirm it is covered.
2. Contact your Volvo Trucks dealer or Volvo Trucks customer service at 1-800-528-6586 (recall RVXX2409).
3. Schedule the software reprogramming — it is done free of charge.

The bigger picture

Official notice

Component
ELECTRICAL SYSTEM:SOFTWARE
Summary
Volvo Trucks North America (Volvo Trucks) is recalling certain 2020-2025 VN, VAH, VHD and VNRE trucks, equipped with Bendix EC80 Advanced Electronic Control Units (ECU). Electrical noise and low signal to the power line carrier may cause the ECU to incorrectly process commands or stop working.
Safety risk
Safety systems that depend on the ECU (Automatic Traction Control, ABS, Electronic Stability Control, Active Cruise Control, and Collison Mitigation System) may have diminished or lost functionality, increasing the risk of a crash.
Remedy
Dealers will reprogram the ECU software, free of charge. Owner notification letters were mailed December 9, 2024. Owners may contact Volvo Trucks customer service at 1-800-528-6586. Volvo Truck's number for this recall is RVXX2409.
