Recall 24V012 covers 248 2020-2023 Pierce International and Freightliner vehicles with Weldon nodes that overheat circuits. Firmware update is free through Pierce and Weldon.
Pierce is recalling 248 2020-2023 International and Freightliner chassis vehicles under recall 24V012 because Weldon 8X16 Input-Output node firmware can leave an output pin powered after a short circuit or wiring failure.

What's wrong?
The V-MUX Node in affected 2020-2023 Pierce International and Freightliner vehicles is an electrical input-output module. It reads signals from the vehicle wiring and uses firmware to switch electrical outputs on and off. One of those outputs is an output pin, the contact point that sends power to a connected circuit.
On recalled vehicles, the current-sensing calibration in the node was not built to specification. During a short circuit or wiring failure, the firmware does not shut off the output pin as intended. That leaves the circuit energized when it should be protected, which results in overloaded electrical circuits.
There is no warning sign before failure. The vehicle can appear to operate normally until a short circuit or wiring fault exposes the problem. The included nodes are identified by firmware version, with version 1.00-1.02 in the recalled range.
Who's affected?
Covers International and Freightliner chassis across the 2020-2023 model years, all using the same V-MUX Node wiring component.

The year and chassis model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Overloaded electrical circuits can overheat and increase the risk of fire. There is no warning sign before failure, so if your VIN is included, schedule the firmware update soon and follow Pierce or dealer instructions until the repair is complete. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2020-2023 Pierce International or Freightliner vehicle is included in this recall.
- Contact a franchised International dealer to schedule the free Weldon 8X16 firmware update that lets the node shut off the output pin after a short circuit or wiring failure.
- Call Pierce customer service at 1-888-974-3723 with questions and reference recall number 24V012 (Pierce recall Pierce 74B332) when you call.
- Bring the recall notice if Pierce mailed one. If not, ask the dealer to look up recall number 24V012.
- Avoid operating equipment with signs of electrical overheating, smoke, or burning smell until the firmware update is complete.
What happens at the repair
At the dealer, an International service technician updates the Weldon node firmware so the system shuts off the output pin as intended after a short circuit or wiring failure. Pierce works with Weldon on the software update, and the recall repair is free. Pierce says vehicle owners who paid for a previous remedy are eligible to ask for reimbursement. Contact Pierce customer service at 1-888-974-3723 and have prior repair paperwork ready so the claim can be reviewed under the recall program.
