SUPPLEMENTARY INFORMATION:
I. Overview
FCA US has determined that certain model year (MY) 2019-2020 Ram
4500/5500 Cab Chassis motor vehicles equipped with Mopar rear brake
hoses and replacement brake hoses sold to FCA US dealers as replacement
parts do not fully comply with paragraph S5.3.1 of FMVSS No. 106, Brake
Hoses (49 CFR 571.106). FCA US filed two noncompliance reports, both
dated October 22, 2020, pursuant to 49 CFR part 573, Defect and
Noncompliance Responsibility and Reports. FCA US subsequently
petitioned NHTSA on November 13, 2020, for an exemption from the
notification and remedy requirements of 49 U.S.C. Chapter 301 on the
basis that this noncompliance is inconsequential as it relates to motor
vehicle safety, pursuant to 49 U.S.C. 30118(d), 49 U.S.C. 30120(h), and
49 CFR part 556, Exemption for Inconsequential Defect or Noncompliance.
Notice of receipt of FCA US's petition was published in the Federal
Register (86 FR 15548), pursuant to 49 U.S.C. 30118 and 30120, with a
30-day public comment period that began on March 23, 2021. No comments
were received. The petition, and all supporting documents, can be found
in docket NHTSA-2020-0112 on the Docket Management System's (FDMS)
website at <a href="https://www.regulations.gov/">https://www.regulations.gov/</a>.
II. Vehicles and Equipment Involved
Approximately 26,961 MY 2019-2020 Ram 4500/5500 Cab Chassis motor
vehicles, manufactured between February 10, 2019, and August 26, 2020,
are potentially involved. Approximately 182 Mopar right rear brake hose
replacement parts, with part numbers 68371722AA and 68371722AB, and
left rear brake hose replacement parts, with part numbers 68371723AA
and 68371723AB, which were manufactured between January 29, 2019, and
August 20, 2020, are potentially involved.
III. Noncompliance
FCA US states that the inside diameter of certain Mopar rear brake
hoses equipped in certain model year (MY) 2019-2020 Ram 4500/5500 Cab
Chassis motor vehicles and sold to FCA US dealers as replacement parts
do not meet the FMVSS No. 106 requirement that every inside diameter of
any section of a hydraulic brake hose assembly is not less than 64
percent of the nominal inside diameter of the brake hose, and therefore
the parts do not comply with paragraph S5.3.1 of FMVSS No. 106. FCA US
explains that this noncompliance is due to crimping of the hose without
use of a mandrel, resulting in the inside diameter of the hose at the
fitting being smaller than designed. Additionally, FCA US states that,
in the worst-case scenario, some of these brake hoses measured 52.8
percent of the nominal inside diameter.
IV. Rule Requirements
Paragraph S5.3.1 of FMVSS No. 106 provides that ``[e]xcept for that
part of an end fitting which does not contain hose, every inside
diameter of any section of a hydraulic brake hose assembly shall be not
less than 64 percent of the nominal inside diameter of the brake hose
(S6.12).''
V. Summary of FCA US's Petition
The following views and arguments presented in this section, ``V.
Summary of FCA US's Petition,'' are the views and arguments provided by
FCA US and do not reflect the views of the Agency.
FCA US described the subject noncompliance and contended that the
noncompliance is inconsequential as it relates to motor vehicle safety.
FCA US states that it ``has completed testing showing that, in this
particular circumstance, there is no safety concern with the
noncompliant brake hose assemblies'' that were built with an under-
specification inside diameter (ID) size. FCA US claims that ``the
testing shows there is no concern for hose rupture and no risk of brake
system failure due to pressure loss.'' FCA US says its testing also
``shows there is no meaningful effect on vehicle braking performance''
for the subject vehicles.
FCA US claims that the subject vehicle ``achieves no more than
2,500 pounds per square inch (PSI) in the brake hose assemblies when
performing FMVSS. 105 testing for stopping distance.'' According to FCA
US, ``FMVSS 106 specifies a minimum burst strength requirement of 7,000
PSI for brake hoses of \1/8\'' or smaller diameter'' and ``the subject
brake hoses have a diameter of \1/8\''.'' The FCA US says its
``internal specification requires the supplier to perform burst testing
daily, and the minimum requirement that all hose assemblies must meet
is 9,000 PSI under the FMVSS. 106 test conditions.'' FCA US says
``[t]he brake hose assemblies containing an out of specification ID all
surpassed the requirement and showed no difference from those
containing a compliant ID.''
FCA US believes that because the ``viscosity of brake fluid at
colder temperatures increases, the flow rate of brake fluid will be
reduced at colder temperatures,'' therefore FCA US characterizes the
cold temperature testing as the worst-case scenario. FCA US tested
noncompliant brake hose assemblies equipped in the subject vehicles and
compliant brake hose assemblies for flow at ambient and at cold
temperature, which included an overnight soak at -30 [deg]C. FCA US
says ``[t]he test was conducted using a panic brake application of 500
Newtons in 0.5 seconds per FMVSS 105 pedal force requirements and then
held for an additional 5 seconds to ensure fluid flow to the wheel
end.'' FCA US found that the ``compliant and noncompliant brake hose
assemblies showed no meaningful difference in the time they each took
to reach 50 bar and 100 bar at either ambient or cold.''
FCA US tested the subject vehicle for stopping distance according
to FMVSS 105 testing procedures for vehicles over 10,000 pounds (lbs.)
Gross Vehicle Weight Rating (GVWR), which FCA US characterizes as the
worst-case scenario. FCA US explains that the test was conducted 6
times ``on a vehicle that was slowed from a speed of 60 mph with a
maximum pedal effort of 150 lbs. to determine if it could meet the
required stopping distance requirements.'' FCA US says it focused on
the ``2nd effectiveness and 3rd effectiveness results'' and used the
best distance to calculate the Best Stop Percentage Margin. FCA US
found that there was ``no meaningful difference between the 2nd
effectiveness and the 3rd effectiveness government specifications or
the more stringent FCA US internal stopping requirements between a
brake hose with an out of specification'' ID and a brake hose with a
compliant ID. FCA US completed two tests with brake hose assemblies
with compliant ID sizes and one test with the subject out of
specification ID size.
FCA US states it is not aware of any crashes, injuries, or customer
complaints associated with the condition.
[[Page 61434]]
FCA US concludes that the subject noncompliance is inconsequential
as it relates to motor vehicle safety, and that its petition to be
exempted from providing notification of the noncompliance, as required
by 49 U.S.C. 30118, and a remedy for the noncompliance, as required by
49 U.S.C. 30120, should be granted.
VI. NHTSA's Analysis
The burden of establishing the inconsequentiality of a failure to
comply with a performance requirement in a standard--as opposed to a
labeling requirement with no performance implications--is more
substantial and difficult to meet. Accordingly, the Agency has not
found many such noncompliances inconsequential.\1\
---------------------------------------------------------------------------
\1\ Cf. Gen. Motors Corporation; Ruling on Petition for
Determination of Inconsequential Noncompliance, 69 FR 19897, 19899
(Apr. 14, 2004) (citing prior cases where noncompliance was expected
to be imperceptible, or nearly so, to vehicle occupants or
approaching drivers).
---------------------------------------------------------------------------
In determining inconsequentiality of a noncompliance, NHTSA focuses
on the safety risk to individuals who experience the type of event
against which a recall would otherwise protect.\2\ In general, NHTSA
does not consider the absence of complaints or injuries when
determining if a noncompliance is inconsequential to safety. The
absence of complaints does not mean vehicle occupants have not
experienced a safety issue, nor does it mean that there will not be
safety issues in the future.\3\
---------------------------------------------------------------------------
\2\ See Gen. Motors, LLC; Grant of Petition for Decision of
Inconsequential Noncompliance, 78 FR 35355 (June 12, 2013) (finding
noncompliance had no effect on occupant safety because it had no
effect on the proper operation of the occupant classification system
and the correct deployment of an air bag); Osram Sylvania Prods.
Inc.; Grant of Petition for Decision of Inconsequential
Noncompliance, 78 FR 46000 (July 30, 2013) (finding occupant using
noncompliant light source would not be exposed to significantly
greater risk than occupant using similar compliant light source).
\3\ See Morgan 3 Wheeler Limited; Denial of Petition for
Decision of Inconsequential Noncompliance, 81 FR 21663, 21666 (Apr.
12, 2016); see also United States v. Gen. Motors Corp., 565 F.2d
754, 759 (D.C. Cir. 1977) (finding defect poses an unreasonable risk
when it ``results in hazards as potentially dangerous as sudden
engine fire, and where there is no dispute that at least some such
hazards, in this case fires, can definitely be expected to occur in
the future'').
---------------------------------------------------------------------------
The main purpose of the vehicle brake hose and its connected
systems is to allow a motor vehicle operator to safely bring the
vehicle to a complete stop. FMVSS No. 106 states that the purpose of
the standard is to reduce deaths and injuries occurring as a result of
brake system failure from pressure or vacuum loss due to hose or hose
assembly rupture, and FMVSS No. 106 contains the constriction
requirement in S5.3.1 to help facilitate that outcome.
NHTSA does not find FCA US's arguments persuasive that failure to
meet the minimum safety requirements of FMVSS No. 106 is
inconsequential to safety. FMVSS No. 105 establishes minimum
requirements related to motor vehicle braking under certain specified
braking conditions, whereas FMVSS No. 106 describes, more broadly,
minimum performance that pertain to brake hoses and brake hose
assemblies to reduce deaths and injuries occurring as a result of brake
system failure from pressure or vacuum loss due to rupture. For
example, FMVSS No. 106 includes tests for constriction, whip
resistance, and tensile strength, among others, that are intended to
ensure a minimum level of safety beyond testing to the specific limited
braking scenarios found in FMVSS No. 105.
FCA US explained that the root cause of the noncompliance is due to
crimping of the hose without use of a mandrel that caused the inside
diameter of the hose at the fitting to be smaller than designed. FCA US
acknowledged in its petition that the hoses do not meet the
requirements of paragraph S5.3.1 of FMVSS No. 106, stating that the
worst cases of noncompliance only have 53% of the nominal inside
diameter. This represents a significant decrease from FMVSS No. 106's
64% minimum safety requirement. NHTSA finds that any potential safety
consequence resulting from FCA US's noncompliance may not present
itself initially, but can emerge over the service life of the product.
Furthermore, over-crimping a brake hose, which FCA US stated caused the
noncompliance, is a common cause of brake hose failure in motor
vehicles, and it can lead to cyclical fatigue that causes a shorter
lifespan than a correctly crimped brake hose. Even if the subject
noncompliant hoses passed a burst test when they were new, the over-
crimping can result in higher stresses on the inside of the hose than
designed and reduce the strength and cycle life of the hose.
In summary, the increased material stress and the loss of strength
and cycle life due to over-crimping can lead to premature failure of
the brake hose assemblies which negatively affects the vehicle's
braking performance and creates a risk to motor vehicle safety.
VII. NHTSA's Decision
NHTSA has determined that FCA US has not met its burden of
persuasion needed for the noncompliance with FMVSS No. 106 to be
considered inconsequential to motor vehicle safety. FCA US's petition
is hereby denied, and FCA US is therefore obligated to provide
notification of, and free remedy for, the aforementioned
noncompliances, pursuant to 49 U.S.C. 30118 and 30120.
