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

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your Mitsubishi Fuso been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Mitsubishi Fuso dealer can also check your VIN. Recall repairs are free.
