Recall 24V032 affects 19 2020-2023 Maxi-Metal-modified Freightliner and Kenworth trucks for overloaded electrical circuits. Firmware update is free through Maxi-Metal and Weldon.
Maxi-Metal is recalling 19 2020-2023 Maxi-Metal Freightliner and Kenworth trucks under recall 24V032 because a short circuit or wiring failure can leave the Weldon 8X16 Input-Output node's output pin on. That can overload electrical circuits and increase the risk of fire; a Freightliner dealer will complete the free repair.

What's wrong?
The Weldon V-MUX 8x16 Input/Output Node on these 2020-2023 Maxi-Metal Freightliner and Kenworth trucks is an electronic control module in the wiring system. It receives electrical commands and switches power to connected equipment through output pins, so circuits turn on and off when the truck body systems call for them.
The problem is in the node firmware, the software that tells the module how to react when a circuit shorts or wiring fails. The current-sensing calibration was not built to specification. Under a short circuit or wiring failure, the firmware does not shut off the affected output pin. That leaves the circuit energized and creates an overloaded electrical circuit instead of cutting power.
Owners are not given an advance symptom to act on. There is no warning sign before failure, so the firmware version on the node, including versions 1.00 to 1.02, is what identifies the recalled equipment.

A matching year and model does not guarantee inclusion. 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 the circuit overheats, so treat the recall as a repair priority and schedule service soon. Repair is free at any franchised Freightliner dealer.
What should I do?
- Check your VIN to confirm your 2020-2023 Maxi-Metal Freightliner or Kenworth truck is included in this recall.
- Contact a franchised Freightliner dealer to schedule the free Weldon 8X16 node firmware update that corrects the overloaded-circuit fire risk.
- Call Maxi-Metal customer service at 1-418-228-6637 with questions and reference recall number 24V032 when you call.
- Bring the recall notice if Maxi-Metal mailed one, and ask the dealer to confirm the software update is complete before returning the truck to service.
- Avoid operating the truck if you smell smoke, see electrical warning lights, or notice overheating until a qualified service technician checks it.
What happens at the repair
At the dealer, a Freightliner technician works with Weldon to update the firmware in the Weldon 8X16 Input-Output node. The update is meant to correct the node behavior so an output pin shuts off when a short circuit or wiring failure occurs. The recall repair is available now, and parts and labor are covered. If you already paid for this firmware repair before the recall notice, contact Maxi-Metal customer service and ask how to submit documentation under the general reimbursement plan on file.
