Volvo VNL trucks may shift into neutral unexpectedly

NHTSA campaign 21V781000 · Reported 2021-10-06 · Volvo Trucks North America

high How serious is it? About this label

This is serious because losing drive power without warning can cause a crash; the notice does not tell owners to stop driving, but get the software update done as soon as you can.

What's wrong, in plain English

On these Volvo VNL trucks, the computer software that controls the transmission has a flaw. While you are driving, the transmission can slip into neutral on its own without you doing anything. When that happens the engine stops sending power to the wheels, so you suddenly lose the ability to speed up or pull away — a dangerous situation in traffic, on a hill, or at a crossing. The dealer fixes it by reloading corrected software into the truck's control module.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your truck is included. 2. Contact your Volvo Trucks dealer, or Volvo Trucks customer service at 1-800-528-6586 (recall RVXX2104), to book the reprogramming. 3. Have the software updated — the repair is free.
