Plain-English summary

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2018 Thomas Built Buses Saf-T-Liner EFX transit buses. The recall addresses a defect in the air brake system where the check valve may not be plumbed correctly. This error can prevent the primary air system from being properly isolated from the secondary air system.

If a rapid loss of air pressure occurs in the secondary system, the incorrectly plumbed check valve can cause rapid air loss in both the secondary and primary systems. This simultaneous loss of pressure can cause the parking brakes to activate suddenly, which increases the risk of a crash.

The recall began on August 12, 2018. DTNA will notify owners, and dealers will inspect and repair the check valve as needed, free of charge. Owners may contact DTNA customer service at 1-800-547-0712 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
