Arboc Specialty Vehicles Spirit OF Freedom Recall 26V137: Rear brake lines may be misrouted, disabling rear ABS

NHTSA campaign 26V137, reported March 11, 2026, 908 vehicles potentially affected.

What this recall means for you

Certain Arboc Spirit of Freedom and Spirit of Mobility transit buses from model years 2018 through 2021 may have had their rear brake lines installed incorrectly. This can cause the anti-lock brake system (ABS) modulator valve to malfunction, and the vehicle then fails to meet federal brake system safety requirements.

Loss of the rear ABS system can increase the risk of a crash, because the wheels may lock or skid during hard braking and the vehicle may not stop as controlled as intended.

The repair is free. ARBOC will provide instructions to reroute and reconnect the rear brake lines. Owner notification letters were mailed April 17, 2026. You can contact ARBOC customer service at 1-866-953-5555, and you should check your vehicle identification number (VIN) for open recalls.
