Mr. Kent Jones of Kernersville, NC, submitted a petition to NHTSA by e-mail dated July 1, 2003, requesting NHTSA to investigate the brake rotors on MY 2002 Nissan Xterra vehicles. The petitioner alleged that the brake rotors in these vehicles overheat and warp from normal usage (alleged defect).

A review of ODI's database for complaints regarding MY 2001 through MY 2003 Nissan Xterra vehicles Start Printed Page 45893identified only two reports related to brake rotor warping; one for a MY 2001 and one for a MY 2002. The complaint for the MY 2002 Nissan Xterra was reported by the petitioner.

Brake rotor warping can result in brake pulsation and shaking when the brake is applied. Brake pulsation, tire or suspension vibration, and similar conditions, while an obvious annoyance to the driver, generally do not cause a driver to lose control of a vehicle. Furthermore, even if left uncorrected, any potential increase in stopping distance will be negligible. Therefore, this condition does not normally constitute a safety defect, even if it occurs with far more frequency.

In view of the foregoing, it is unlikely that NHTSA would issue an order for the notification and remedy of an alleged safety-related defect as defined by the petitioner in MY 2002 Nissan Xterra vehicles at the conclusion of an investigation. Therefore, in view of the need to allocate and prioritize NHTSA's limited resources to best accomplish the agency's safety mission, the petition is denied.
