SUBJECT:

Safety Recall C10120 – Front Leaf Spring Shackle Bolts

MODELS:

FEC9T(FE180)

VEHICLES INVOLVED:

Certain 2020-2021 model year 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 front leaf spring shackle bolt tightening process on certain 2020-2021 model year FEC9T(FE180) Mitsubishi Fuso trucks. On certain trucks, the front leaf spring rear lower shackle bolts were insufficiently tightened during initial assembly. If the vehicle continues to be operated in this condition, the bolt could back out and fall onto the roadway, becoming a road hazard, causing a crash without warning.

MODIFICATION:

The front leaf spring rear lower shackle and bolt will be inspected. If the bolt has backed out and has abnormally worn the shackle, the shackle and hardware will be replaced and tightened to the correct torque specification. If there is no damage, the existing bolt will be tightened properly.

PARTS PROCUREMENT:

Due to the limited number of affected vehicles, repair parts must be ordered using the Recall Parts Order Form on Fusonet.
