The defect
Daimler Trucks North America (DTNA) is recalling certain 2015-2017 Freightliner M2 Business Class, 108SD, and 114SD vehicles. The affected vehicles might not have a required check valve installed in one of the ports of the spring brake modulation valve. Without the valve, the primary air system is not isolated from the secondary air system.
The risk
A rapid loss of air pressure in the secondary system could cause a similar rapid loss of pressure in the primary system, which may lead to a sudden application of the parking brakes. This could increase the risk of a crash.
The remedy
DTNA will notify owners, and dealers will inspect the vehicles, installing a check valve, as necessary, free of charge. The recall began on August 24, 2017. Owners may contact DTNA customer service at 1-800-745-8000. DTNA's number for this recall is FL-740.
