American Honda Motor Co., Inc., Receipt of Petition for Decision
of Inconsequential Noncompliance
AGENCY: National Highway Traffic Safety Administration, DOT.
ACTION: Receipt of petition.
-----------------------------------------------------------------------
SUMMARY: American Honda Motor Co., Inc. (Honda) \1\ has determined that
the tire pressure monitoring system (TPMS) low tire pressure warning
for certain model year (MY) 2011 and 2012 Acura TSX passenger cars
equipped with accessory 18-inch diameter wheels sold at Honda
dealerships do not comply with paragraph S4.2(a) of Federal Motor
Vehicle Safety Standard (FMVSS) No. 138 Tire Pressure Monitoring
Systems. Honda has filed an appropriate report dated September 27,
2012, pursuant to 49 CFR Part 573, Defect and
[[Page 43966]]
Noncompliance Responsibility and Reports.
---------------------------------------------------------------------------
\1\ American Honda Motor Co., Inc. is manufacturer of motor
vehicles and is registered under the laws of the state of
California.
---------------------------------------------------------------------------
Pursuant to 49 U.S.C. 30118(d) and 30120(h) (see implementing rule
at 49 CFR part 556), Honda submitted a petition for an exemption from
the notification and remedy requirements of 49 U.S.C. Chapter 301 on
the basis that this noncompliance is inconsequential to motor vehicle
safety.
This notice of receipt of Honda's petition is published under 49
U.S.C. 30118 and 30120 and does not represent any agency decision or
other exercise of judgment concerning the merits of the petition.
Vehicles involved: Affected are approximately 212 model years 2011
and 2012 Acura TSX passenger cars equipped with accessory 18-inch
diameter wheels sold at Honda dealerships.
NHTSA notes that the statutory provisions (49 U.S.C. 30118(d) and
30120(h)) that permit manufacturers to file petitions for a
determination of inconsequentiality allow NHTSA to exempt manufacturers
only from the duties found in sections 30118 and 30120, respectively,
to notify owners, purchasers, and dealers of a defect or noncompliance
and to remedy the defect or noncompliance. Therefore, these provisions
only apply to the subject 212 \2\ vehicles that Honda no longer
controlled at the time it determined that the noncompliance existed.
---------------------------------------------------------------------------
\2\ Honda's petition, which was filed under 49 CFR part 556,
requests an agency decision to exempt Honda as a motor vehicle
manufacturer from the notification and recall responsibilities of 49
CFR part 573 for the affected vehicles. However, a decision on this
petition cannot relieve vehicle distributors and dealers of the
prohibitions on the sale, offer for sale, introduction or delivery
for introduction into interstate commerce of the noncompliant motor
vehicles under their control after Honda notified them that the
subject noncompliance existed.
---------------------------------------------------------------------------
Noncompliance: Honda explains that the noncompliance is that when
the accessory wheels and tires are installed on the subject vehicles,
the preset TPMS warning level cannot be adjusted to warn at a higher
cold inflation pressure for the accessory tires. The TPMS system on
these vehicles is set for the OEM 17-inch diameter wheels with
recommended 230kPa (33psi), not the accessory 18-inch wheels with
recommended 260kPa (38psi).
The TPMS warning level is based on the OEM tires, which is no lower
than 183kPa (26.5psi), while the accessory wheel should be set to warn
at no lower than 204kPa (29.5psi). Therefore, the vehicles do not
comply with paragraph S4.2(a) of FMVSS No. 138.
Rule text: Paragraph S4.2(a) of FMVSS No. 138 requires in pertinent
part:
S4.2 TPMS detection requirements. The tire pressure monitoring
system must:
(a) Illuminate a low tire pressure warning telltale not more
than 20 minutes after the inflation pressure in one or more of the
vehicle's tires, up to a total of four tires, is equal to or less
than either the pressure 25 percent below the vehicle manufacturer's
recommended cold inflation pressure, or the pressure specified in
the 3rd column of Table 1 of this standard for the corresponding
type of tire, whichever is higher;
Summary of Honda's Analysis and Arguments
A total of approximately 848 wheels, or 212 complete wheel sets,
were sold to Acura dealerships by Honda between November 2010 and April
2012. These wheels were sold with a replacement tire pressure placard,
in accordance with the requirements of FMVSS No. 110 ``Tire Selection
and Rims'', indicating an inflation pressure of 260kPa (38psi) for the
recommended 225/45ZR 18 tire size with an 95Y load capacity rating.
There have been no reports of crashes, injuries or death as a result of
the accessory tire being used with the standard TPMS threshold.
After the beginning of retail sales of 2012 model year Acura TSX
models Honda discovered that the recommended electronic method of
updating the TPMS setting for these accessory wheels would incorrectly
inform technicians that the adjustments had been completed
successfully. The result is that the TPMS warning threshold remains at
the standard setting for the OEM 17-inch diameter wheels of not less
than 183kPa (26.5psi) for the standard recommended tire pressure of
230kPa (33psi). The minimum allowable TPMS threshold for the 18-inch
diameter accessory wheels would be 193kPA (28psi), based on the
recommended pressure of 260kPa (38psi) as indicated on the tire
pressure placard.
Honda believes that this noncompliance is inconsequential to motor
vehicle safety because even at the lower TPMS threshold, adequate load
capacity remains for the tires on these vehicles. Honda indicated that
it also conducted dynamic testing to confirm that the handling and
stability of the vehicle is not adversely affected at the lower
pressures.
The maximum load capacity for each of the P225/45ZR 18 95Y tires
for this vehicle is 575 kilograms (1,268 lbs) at 230kPa (33psi),
calculated using the Japan Automotive Tyre Manufacturer's Association
(JATMA) method, as recognized by NHTSA in FMVSS No. 110. The maximum
allowable load according to the Gross Axle Weight Ratings (GAWR) for a
2011 or 2012 Acura TSX is 546.6 kilograms (1,207.2 lbs) for each front
tire and 514.9 kilograms (1,135 lbs) for each rear tire, well within
the load capacity specified by JATMA.
At 80% of the lower pressure for the OEM 17-inch tires (230kPa
(33psi), as opposed to the 260kPa (38psi) recommended on the tire
pressure placard for the 18-inch accessory tires), the low tire
pressure indicator will illuminate at 183kPa (26.5psi).
Honda has additionally informed NHTSA that it has corrected the
noncompliance so that all future vehicles will comply with FMVSS No.
138.
In summation, Honda believes that the described noncompliance of
its vehicles is inconsequential to motor vehicle safety, and that its
petition, to exempt from providing recall notification of noncompliance
as required by 49 U.S.C. 30118 and remedying the recall noncompliance
as required by 49 U.S.C. 30120 should be granted.
