Mitsubishi Fuso Truck of America, Inc. (MFTA) is recalling certain 2019-2021 FEC7T, FECZT, and FEC9T vehicles. The brake booster vacuum pump assembly may be affected by heat radiating off the exhaust manifold during normal engine operation. This heat can cause the diaphragm in the pump to crack, resulting in loss of vacuum in the vacuum pump.
If loss of vacuum occurs, power brake assist may become inoperable, increasing the risk of a crash.
Dealers will replace the vacuum pump and install exhaust heat shields, free of charge. Owner notification letters were mailed December 15, 2021. Owners may contact MFTA customer service at 1-877-711-0707.
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.
