Service Brakes, Air

NHTSA campaign 17V402000 · announced June 26, 2017 · filed by Daimler Trucks North America Llc · 1,550 units affected

The problem

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.

What to do

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.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
