Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the
noncompliance decision.:
May 2019, DTNA received a report of a vehicle pulling to the right, due to an unknown cause, during a
brake event. Upon repairing the vehicle, the dealer was able to isolate the failure to the right single
modulator valve. May 2019-July 2019, DTNA performed a preliminary population and warranty seek.
Warranty indicated 6 claims of a vehicle pull event during an external brake request, where 3 claims
were from a single customer. DTNA had requested parts to be returned for further review. July 2019,
DTNA notified NHTSA Office of Defects Investigation (ODI) of an ongoing investigation relating to brake
pull during an active brake request. August 2019, DTNA received the returned parts and began an
electrical and functional test. Testing indicated parts were within specification. During a functional
evaluation, a pressure differential in air release timing was observed. The parts were shipped to the
supplier for component breakdown and further evaluation. August – September 2019, Supplier evaluated
the returned parts and found blockage of the inlet solenoid from magnesium chloride corrosion
deforming the O-ring. October 2019, DTNA and supplier began reviewing vehicle routes and chemical
wash processes, with ongoing corrosion testing with magnesium chloride and requests to the field for
additional returned parts. 34 valves returned for review from single customer. Failed valves appear to be
isolated to only the right valve and a single route. November 2019, DTNA shared an update of the
ongoing investigation with NHTSA ODI, including the low claim rate. While the investigation continued,
the modulator valves in production vehicles were spaced away from the frame rails to potentially reduce
opportunity of corrosion. January 2020, DTNA provided a status update to NHTSA ODI on testing to
understand detectability and severity. Ongoing corrosion testing and analysis continued by DTNA and
supplier. Corrosion testing with MgCl2 and NaCl was unable to replicate failures observed in field.
February 2020 – April 2020, DTNA worked with customers in various locations to randomly sample parts
to inspect. Twelve valves were returned outside of the salt belt region and 12 inside the salt belt region of
the Northeastern United States and shipped to the supplier for further evaluation. There were no
indications of a valve malfunction on the returned parts. There were still no reports of vehicle pull during
active brake request since mid-2019. May 2020, an additional field service report indicated 13 additional
failures on a separate fleet. DTNA provided a status update with NHTSA ODI on the additional field
report with pending review of returned parts. Customer provided 13 valves from different trucks for
review and these were sent to the supplier for further evaluation. June 2020, DTNA continued corrosion
testing and began analyzing chemical wash and thermal impacts to the valve. Supplier provided a report
of one returned valve that appeared to share a similar failure mode as the initial parts returned from
mid-2019. The remaining 12 valves are under review. From the returned valves prior to May, it was
believed the issue to be isolated to a single customer because there were no confirmed reports from
other customers at this time. The additional field complaint and data obtained in May/June 2020
suggested that additional customers are also impacted in different locations. With eight claims of
failures experienced in the field, even though the failure mode is not fully understood, the issue appeared
to be more systemic, and therefore DTNA, with an abundance of caution, decided to initiate a voluntary
recall campaign to address potential vehicle pull during an active brake request.

Defect / Noncompliance Description
For this Defect/Noncompliance:
Describe the defect or noncompliance:
On certain vehicles, chemical corrosion could affect the functionality of the single brake modulator valve, which may result in slow release timing of brakes on the affected side. Regular service brakes are unaffected.
Describe the safety risk:
A slow release of the brake on one side during an active brake request (ie. automatic braking events) could lead to a brake pull resulting in a sudden change in vehicle direction due to uneven braking on the front axle increasing the risk of a motor vehicle crash.

Chronology of Defect / Noncompliance Determination
Provide the chronology of events leading up to the defect decision or test data for the noncompliance decision.:
May 2019, DTNA received a report of a vehicle pulling to the right, due to an unknown cause, during a brake event. Upon repairing the vehicle, the dealer was able to isolate the failure to the right single modulator valve. May 2019-July 2019, DTNA performed a preliminary population and warranty seek. Warranty indicated 6 claims of a vehicle pull event during an external brake request, where 3 claims were from a single customer. DTNA had requested parts to be returned for further review. July 2019, DTNA notified NHTSA Office of Defects Investigation (ODI) of an ongoing investigation relating to brake pull during an active brake request. August 2019, DTNA received the returned parts and began an electrical and functional test. Testing indicated parts were within specification. During a functional evaluation, a pressure differential in air release timing was observed. The parts were shipped to the supplier for component breakdown and further evaluation. August – September 2019, Supplier evaluated the returned parts and found blockage of the inlet solenoid from magnesium chloride corrosion deforming the O-ring. October 2019, DTNA and supplier began reviewing vehicle routes and chemical wash processes, with ongoing corrosion testing with magnesium chloride and requests to the field for additional returned parts. 34 valves returned for review from single customer. Failed valves appear to be isolated to only the right valve and a single route. November 2019, DTNA shared an update of the ongoing investigation with NHTSA ODI, including the low claim rate. While the investigation continued, the modulator valves in production vehicles were spaced away from the frame rails to potentially reduce opportunity of corrosion. January 2020, DTNA provided a status update to NHTSA ODI on testing to understand detectability and severity. Ongoing corrosion testing and analysis continued by DTNA and supplier. Corrosion testing with MgCl2 and NaCl was unable to replicate failures observed in field. February 2020 – April 2020, DTNA worked with customers in various locations to randomly sample parts to inspect. Twelve valves were returned outside of the salt belt region and 12 inside the salt belt region of the Northeastern United States and shipped to the supplier for further evaluation.
