NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE06-007.

THE POPULATION OF 116,000 VEHICLES IS AN ESTIMATE BASED ON AMERICAN HONDA MOTOR COMPANY (AHM) DATA IDENTIFYING ORIGINAL STATE OF SALE OR DELIVERY.THE SUBJECT VEHICLES (SV) UTILIZE LIGHT WEIGHT COIL SPRINGS MANUFACTURED FROM HIGH STRENGTH STEEL (HSS).

IF THE COATING MATERIAL OF A HSS SPRING IS BREACHED, CORROSIVE ELEMENTS (SALT) MAY ATTACK THE SPRING.SPRING CORROSION RESULTS IN A STRESS RISER AND MAY CAUSE A FRACTURE.DEPENDING ON THE LOCATION WHERE THE SPRING BREAKS, THE JAGGED EDGE MAY PIERCE THE TIRE; A RAPID DEFLATION OF THE TIRE MAY OCCUR AND CAN RESULT IN A LOSS OF CONTROL OR CRASH.SV SPRING FAILURE MECHANICS AND TIRE CONTACT LIKELIHOOD ARE DISCUSSED IN AN AHM PRESENTATION TO ODI DATED APRIL 20TH, 2006 (AVAILABLE ON ODI?S WEB SITE; WWW-ODI.NHTSA.DOT.GOV).

AHM?S PRESENTATION IDENTIFIED TWO MECHANISMS WHICH CAUSE THE SPRING COATING TO BECOME BREACHED; 1) CONTACT WITH THE LOWER SPRING SEAT, AND 2) ENTRAPMENT OF ABRASIVE MATERIALS BETWEEN THE SILENCER TUBE AND SPRING.THE PRESENTATION COMPARED SV SPRING FRACTURE RATES TO THE HONDA MDX MODEL, A SISTER VEHICLE RECALLED FOR FRONT SPRING FRACTURE UNDER NHTSA RECALL 05V385, AND TO OTHER VEHICLES INVESTIGATED AND OR RECALLED FOR FRONT SPRING FRACTURE.THE SPRING FRACTURE RATE FOR THE SV, WHICH IS ABOUT HALF THE RATE OF THE MDX MODEL EVEN THOUGH THE SV'S HAVE ONE YEAR LONGER IN SERVICE, IS COMPARABLE TO RATES OBSERVED IN PRIOR SPRING FRACTURE INVESTIGATIONS THAT WERE CLOSED WITH NO RECALL AND LOW IN COMPARISON TO INVESTIGATIONS THAT HAVE RESULTED IN A SAFETY RECALL.OF THE 7 REPORTS ODI IDENTIFIED ALLEGING TIRE DAMAGE DUE TO SPRING FRACTURE, 6 INVOLVED SPRING-TIRE CONTACT WHICH RESULTED IN SLOW OR NO LOSS OF AIR PRESSURE; ODI WAS UNABLE TO VERIFY THE ONE REPORT ALLEGING A PUNCTURE OCCURRED.ODI NOTES THAT THE SV FRONT SPRING DIFFERS FROM THE MDX SPRING IN THAT IT HAS A SINGLE SILENCER TUBE (UPPER ONLY, AS OPPOSED TO UPPER AND LOWER ON THE MDX) WHICH IS, ACCORDING TO AHM, LOCATED IN AN AREA LESS LIKELY TO RESULT IN A TIRE PUNCTURE SHOULD A FRACTURE OCCUR.A DEFECT TREND HAS NOT BEEN IDENTIFIED AT THIS TIME AND FURTHER USE OF AGENCY RESOURCES IS NOT WARRANTED.ACCORDINGLY, THIS INVESTIGATION IS CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY THE CIRCUMSTANCES.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
