What's wrong?
The trailer ABS control unit on these 2010-2025 Mack Mru and Terrapro (Te) towing vehicles is part of the air brake system for an attached trailer. In normal use, the truck supplies trailer brake control through end-of-frame air connections, while ABS wiring and a dash warning lamp support the trailer anti-lock brake function. The lamp tells the driver when the trailer ABS has a fault.
On affected trucks, that warning lamp and the related circuits were not installed for towing setups built to customer specifications. The truck has trailer brake control valves and air connections, but the wiring needed to enable trailer anti-skid braking is missing. Mack traced the issue to an insufficient engineering review of customer engineering changes.
There are no driver warnings associated with this issue. There is no warning sign before failure, because the missing lamp and circuitry are not something an owner will feel during a normal pre-trip or brake pedal check.

What's the safety risk?
Without a functioning anti-lock brake system, the trailer is at risk of not braking as intended, increasing crash risk. There is no warning sign before this issue. Drive cautiously, leave extra following distance, and schedule service soon. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2010-2025 Mack Mru or Terrapro (Te) is included in this recall.
- Watch for Mack's owner letter if you have not received it, then keep it with the truck's service paperwork.
- Contact a franchised Mack dealer and reference recall number 25V030 when asking about the free ABS warning-light and trailer anti-lock brake circuitry repair.
- Schedule the repair once the dealer confirms the parts and procedure are ready for your truck.
- Drive with extra space when towing until the repair is complete, since the trailer anti-lock brake system can fail to brake as intended.
What happens at the repair
Once the dealer repair is available, a Mack technician will add the missing ABS warning light and the circuitry that controls the anti-lock brake function for an attached trailer. The recall repair is free, with parts and labor covered. If you've already paid out of pocket for ABS warning light or trailer ABS circuitry work tied to this recall, Mack's standard reimbursement plan covers documented expenses. Keep your repair paperwork and ask Mack customer service how to submit it.
