Re: Vacuum Pump
Group: 35 Models: FE
SUBJECT:
Safety Recall C10118 – Vacuum Pump
MODELS:
FECZT (FE140), FEC7T (FE160), FEC9T(FE180)
VEHICLES INVOLVED:
Certain 2019-2021 model year FECZT, FEC7T, and FEC9T trucks.
A list of vehicles your Dealership has sold that require this Recall can be found on the Dealer’s “Open Campaigns”
list supplied by MFTA via Fusonet. Some individual vehicles described above may not need the Recall as the
repairs may have already been performed. Always check the “VIN Inquiry” tab under “Service” or “Warranty” on
Fusonet to verify that the VIN requires this Safety Recall.
Important note: It is a violation of Federal law for a dealer to deliver a new or used motor vehicle covered
by this Recall Information Bulletin, under a sale or lease, until the Safety Recall has been completed.
OWNER NOTIFICATION:
Owners of affected vehicles will be notified by mail.
CONDITION:
Mitsubishi Fuso Truck of America, Inc. has decided that a defect, which relates to motor vehicle safety, exists in the
vacuum pump on certain 2019-2021 model year FECZT (FE140), FEC7T (FE160) and FEC9T(FE180) Mitsubishi
Fuso trucks. On some light duty trucks, the vacuum pump assembly is affected by excessive heat generated prior
to performing safety recall C10114 may cause the vacuum pump to fail prematurely. This heat causes the
diaphragm in the pump to crack, resulting in loss of vacuum in the vacuum pump. If the vehicle continues to be
operated in this condition, the low vacuum lamp will illuminate and as the vacuum pump loses vacuum, the brake
pedal will become hard. In the worst case, the power brake assist will become inoperable, causing a crash.
MODIFICATION:
The vacuum pump will be replaced with an improved pump assembly and exhaust heat shields will be added to
protect the pump from excessive heating.
RECALL CLAIM SUBMITTAL:
Reimbursement claims are filed through FALCON using the Field Fix claim type. Enter all requested information.
The system will automatically populate the labor allowance and parts kit.

SAFETY RECALL NOTIFICATION – C10118 – Vacuum Pump
NHTSA SAFETY RECALL – 20V645
Dear Mitsubishi Fuso Truck Owner:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Mitsubishi Fuso Truck of America, Inc. has decided that a defect, which relates to motor vehicle safety, exists in the
vacuum pump on certain 2019-2021 Model Year FECZT, FEC7T and FEC9T Mitsubishi Fuso trucks. The purpose
of this letter is to explain what the recall is about and to keep you informed of MFTA’s implementation plan. We are
currently making preparations to implement the Safety Recall remedy. We will send you another notification when
the remedy is available
What is the problem?
On certain affected vehicles, the vacuum pump internal diaphragm may have been overheated by exhaust stud
looseness remedied through Safety Recall C10114 (20V646). If the vehicle continues to be operated in this condition,
the vacuum pump diaphragm could tear, causing a loss of vacuum. In the worst case, the vacuum loss could cause
the power brake assist to become inoperative, resulting in extended braking distances and a crash without warning.
What should you do in the interim?
We appreciate your patience while we prepare the remedy. In the meantime, if the vacuum warning lamp illuminates,
or the brake pedal become hard, please make an appointment with your authorized Mitsubishi Fuso dealer as soon
as possible to have the vacuum system in your vehicle inspected and repaired, and if your vehicle remains open for
the C10114 Exhaust Stud Safety Recall, please have that recall completed immediately.
