What's wrong?
The 2015-2018 Peterbilt trucks in this recall use an anti-lock brake system controller to manage wheel lockup during hard braking. That controller also works with electronic stability control, which helps the truck stay controlled when braking or turning. The dash ABS warning light is supposed to alert the driver when the ABS loses battery or ignition power.
On affected 567, 579, T660, T800, W900, T680, and T880 trucks, the warning light does not come on when that power loss happens. The problem is tied to the cab control module software and the Bendix ABS hardware. The controller hardware changed, but the cab control module input settings were not matched to that change, so the truck does not warn the driver that ABS power is gone.
There is no warning sign before failure. The issue is that the expected warning light stays off, so the driver has no dash alert that the ABS is not powered.
Who's affected?
Spans seven truck models across four model years, with electronic stability control and anti-lock brake system components tied to each model-year pairing.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
With ABS offline, the truck lacks anti-lock braking support, and a driver who does not know the system is not working faces increased crash risk. Schedule the software update soon. Until it is completed, pay close attention to brake and ABS warnings. Repair is free at any franchised Peterbilt dealer.
What should I do?
- Check your VIN to confirm your 2015-2018 Peterbilt 567, 579, T660, T800, W900, T680, or T880 truck is included in this recall.
- Contact a franchised Peterbilt dealer to schedule the free NAMUX cab-control-module software update that corrects the missing ABS warning-light alert.
- Reference recall number 18V368 when you call, and bring the recall notice if Peterbilt mailed one.
- Call Peterbilt customer service at 1-918-259-3258 with questions about scheduling or dealer handling.
- Drive with extra following distance until the repair is complete, and stop using the truck if ABS or stability-control warnings appear.
What happens at the repair
At the dealer, a Peterbilt technician updates the NAMUX software in the cab control module so the ABS warning light works as required if the ABS controller loses battery or ignition power. The software update and labor are free under the recall. Peterbilt has a general reimbursement plan on file for owners who already paid for this repair before the recall notice. If you have prior repair paperwork for the same condition, ask the service desk how to submit documented expenses under that plan.
