I. AML's Petition: Pursuant to 49 U.S.C. 30118(d) and 30120(h) and the rule implementing those provisions at 49 CFR part 556, AML 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 AML'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.

II. Vehicles Involved: Affected are approximately 3,282 of the following AML model passenger cars manufactured from September 2009 through October 2013:

III. Noncompliance: AML explains that during testing of the TPMS it was noted that the fitment of an incompatible wheel and tire unit was correctly detected and the malfunction indicator illuminated as required by FMVSS No. 138. However, when the vehicle ignition was deactivated and then reactivated after a five minute period, there was no immediate re-illumination of the malfunction indicator as required when the malfunction still exists. Although the malfunction indicator does not re-illuminate immediately after the vehicle ignition is reactivated, it does illuminate within 40 seconds after the vehicle accelerates above 23 mph.

Rule Text: Paragraph S4.4(c)(2) of FMVSS No. 138 requires in pertinent part:

S4.4 TPMS Malfunction.

(c) Combination low tire pressure/TPMS malfunction telltale. The vehicle meets the requirements of S4.4(a) when equipped with a combined Low Tire Pressure/TPMS malfunction telltale that:Start Printed Page 38508

(2) Flashes for a period of at least 60 seconds but no longer than 90 seconds upon detection of any condition specified in S4.4(a) after the ignition locking system is activated to the “On” (“Run”) position. After each period of prescribed flashing, the telltale must remain continuously illuminated as long as a malfunction exists and the ignition locking system is in the “On” (“Run”) position. This flashing and illumination sequence must be repeated each time the ignition locking system is placed in the “On” (“Run”) position until the situation causing the malfunction has been corrected. . . .

V. Summary of AML's Analyses: AML stated its belief that the subject noncompliance is inconsequential to motor vehicle safety for the following reasons:

(A) AML stated that although the malfunction indicator does not re-illuminate immediately after the vehicle is restarted, it generally will illuminate shortly thereafter, and in any event it will illuminate in no more than about 40 seconds, even in vehicles containing the noncompliance. Once a vehicle has started and is accelerating above 23 mph for a period of 15 seconds, the TPMS will seek to confirm the sensors fitted to the vehicle. If a sensor is not fitted, the TPMS will detect this within a further period of 15-20 seconds (up to a maximum of 25 seconds) and the TPMS malfunction indicator will illuminate correctly. Once the malfunction indicator is illuminated, it will remain illuminated throughout that ignition cycle, regardless of the vehicle's speed.

(B) AML also stated that if the TPMS fails to detect the wheel sensors, the TPMS monitor will display on the TPMS pressures screen “—” warning the driver that the status of the wheel sensor is unconfirmed. Once the vehicle starts moving, the system will then accurately determine if a sensor is present or not.

(C) AML says that the noncompliance is confined to one particular aspect of the functionality of the otherwise compliant TPMS malfunction indicator. All other aspects of the low-pressure monitoring system functionality are fully compliant with the requirements of FMVSS No. 138.

(D) AML is not aware of any customer complaints, field communications, incidents or injuries related to this condition.

AML has additionally informed NHTSA that all unsold vehicles in AML's custody and control will have the TPMS Electronic Control Unit reprogrammed prior to being sold.

In summation, AML believes that the described noncompliance of the subject vehicles is inconsequential to motor vehicle safety, and that its petition, to exempt AML 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.

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, any decision on this petition only applies to the subject vehicles that AML no longer controlled at the time it determined that the noncompliance existed. However, any decision on this petition does not relieve vehicle distributors and dealers of the prohibitions on the sale, offer for sale, or introduction or delivery for introduction into interstate commerce of the noncompliant vehicles under their control after AML notified them that the subject noncompliance existed.
