What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect in the braking system that can cause sudden parking brake activation and increase the risk of a crash, meeting the criteria for a Severe rating.

Plain-English summary

Daimler Trucks North America LLC (DTNA) is recalling certain 2017-2018 Thomas Built Buses Saf-T-Liner EFX school buses. The recall involves 109 vehicles where the check valve for the air brake system may not be plumbed correctly. This defect can prevent the primary air system from being 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 causes the parking brakes to activate suddenly, which increases the risk of a crash.

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