The defect

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.

The risk

If loss of vacuum occurs, power brake assist may become inoperable, increasing the risk of a crash.
