Make: Freightliner
Model: Cascadia
Model Yr. Start: 2021 Model Yr. End: 2021

Descriptive Information: Freightliner Cascadia vehicles built with an Automated Manual Transmission
(AMT) with certain clutches between the affected build dates.
Number potentially involved: 6,105 Estimated percentage of involve with defect: 1%
Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance: Clutch damper failure at low miles.
Describe the safety risk: Flange failure may cause loose parts to fall into the clutch pressure plate
assembly and potentially affect clutch disengagement. Even though this has not been reported in the
field, this may cause the vehicle to lurch and cause unexpected vehicle movement.
Identify any warning which can precede or occur: It is expected that a failure would happen over a
period of time with increasing noise and vibration.
If applicable, identify the manufacture of the defective or noncompliant component: Schaeffler
Involved Components
Component Name: Clutch
Component Description: Automated Manual Transmission Clutch
Component Part Number: A02-14108-001
Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision: In late 2020, DTNA became aware of a potential clutch failure and promptly
began a recall (FL869, a/k/a 20V-742) while still investigating root cause and population, and while still
trying to determine if any vehicles in the field were actually affected. January 2021, DTNA received the
first report of a clutch failure, at low miles. DTNA began investigation to understand the contributing
factor of this failure and sent parts to the supplier for analysis. March 2021, DTNA received a second
report of a clutch failure. DTNA sent the second set of failed parts to the supplier for analysis. March 18,
2021 out of an abundance of caution, DTNA decided to conduct a voluntary safety recall while continuing
to investigate root cause and population. Though the failures seem similar to the defect in FL869, DTNA
chose not amend that recall so the vehicles could be tracked for their completion of the revised remedy.
At this time, the analysis of these parts has not been completed and root cause has not been established.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for
reimbursement. On affected vehicles, the clutch will be replaced. Repairs will be performed by Daimler
Trucks North America authorized service facilities. Details of the reimbursement plan will be included in
the owner’s notification letter.
Identify the Recall Schedule
Describe the recall schedule for notifications: Customer notification will be made by first class mail
using Daimler Trucks North America records to determine the customers affected.

Though the failures seem similar to the defect in FL869, DTNA chose not amend that recall so the vehicles could be tracked for their completion of the revised remedy. At this time, the analysis of these parts had not been completed and root cause had not been established. May 2021, DTNA has since received information clarifying that the Schaeffler-LUK Damper Flange failures were not a result of a supplier-manufacturing defect. Rather, during the root cause analysis process, it was discovered that these failures were due to an installation issue specific to these two units and not known or believed to be on any other units. The failure of the two clutches were caused by improper installation of the transmission to the engine flywheel housing, which mimicked a hardness and hydrogen embrittlement issue. Due to this information, DTNA has reduced the scope of this recall to the two vehicles that had reported failures.
Identify the Remedy
Describe the defect/noncompliance remedy program, including the manufacture’s plan for reimbursement. On both affected vehicles, the clutches have been replaced. Repairs were performed by Daimler Trucks North America authorized service facilities at no charge to the customers.
