What's wrong?
The spring brake valve on 2015-2017 Wabash National Van trailers is part of the air brake system that holds the trailer parked. When the driver sets the parking control, air pressure is released in a controlled way so the spring brakes apply and keep the trailer from rolling. The valve has to route that air cleanly every time the trailer is parked.
On affected trailers, certain Bendix SR-5 spring brake valves were machined without the correct check valve seat radius. That small internal shape helps the valve seal and move air as designed. With the seat machined incorrectly, the valve can delay spring brake application while parking, so the trailer takes longer than expected to settle onto its parking brakes.
This condition can happen without warning. Before the tractor is uncoupled, the operator can hear air leaking from the dash-mounted park control valve or from the red glad hand when it is disconnected; that leak continues until air pressure is depleted.
Who's affected?
Spans the 2015, 2016, and 2017 model years, all tied to the same parking brake component.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific trailer is included.
What's the safety risk?
A delayed spring brake application means the trailer can roll away after it decouples from the tractor, increasing crash or injury risk. Listen for an air leak at the dash mounted park control valve or red glad hand when the trailer is disconnected. If you hear that leak, keep the trailer parked and contact Wabash National. Repair will be free at any franchised Wabash National dealer once available.
What should I do?
- Check your VIN to confirm your 2015-2017 Wabash National Van trailer is included in this recall.
- Watch for Wabash National's owner notice and remedy kit instructions if you have not received them.
- Contact Wabash National customer service at 1-765-771-5300 and reference recall number 16V484 when you ask about the free SR-5 spring-brake-valve remedy kit.
- Secure the trailer against rollaway risk until the repair is complete, since delayed spring-brake application can let the trailer roll after it is decoupled from the tractor.
- Follow the remedy kit instructions or have a qualified trailer service technician repair the affected SR-5 relay valve before returning the trailer to normal parking use.
What happens at the repair
The final dealer repair is not marked available in this recall data. Wabash National's planned fix is a free remedy kit with instructions to repair affected Bendix SR-5 trailer relay valves, the valves tied to delayed spring-brake application while parking. Once the repair opens, parts and labor are covered under the recall. Wabash National has a general reimbursement plan on file, so if you already paid for a related SR-5 relay valve repair, contact Wabash National Customer Service with documentation and ask how to submit the claim.
