2002 Infiniti QX4

Suspension:front

NISSAN IS RECALLING CERTAIN MODEL YEAR 1996-2004 PATHFINDER AND MODEL YEAR 1997-2003 INFINITI QX4 VEHICLES ORIGINALLY SOLD, OR CURRENTLY REGISTERED IN, CONNECTICUT, DELAWARE, IOWA, ILLINOIS, INDIANA, MASSACHUSETTS, MAINE, MARYLAND, MICHIGAN, MINNESOTA, MISSOURI, NEW HAMPSHIRE, NEW JERSEY, NEW YORK, OHIO, PENNSYLVANIA, RHODE ISLAND, VERMONT, WASHINGTON D.C., WEST VIRGINIA AND WISCONSIN. IN AREAS OF THE COUNTRY IN WHICH HEAVY CONCENTRATIONS OF ROAD SALT ARE USED, A MIXTURE OF SNOW/WATER AND SALT MAY ENTER AN ASSEMBLY LOCATION HOLE IN THE UPPER STRUT HOUSING, CAUSING WATER TO COLLECT AT THE MATING SURFACE OF THE STRUT HOUSING PANEL AND THE INNER HOOD LEDGE ASSEMBLY. OVER TIME, THIS SNOW/WATER AND SALT INTRUSION MAY RESULT IN CORROSION OF THE STRUT TOWER HOUSING IN SOME SUBJECT VEHICLES.

Consequence: THE STRUT HOUSING MAY CRACK AND PULL AWAY FROM THE INNER HOOD LEDGE ASSEMBLY. THIS MAY LEAD TO GRINDING NOISES, INCREASED STEERING EFFORT, AND POSSIBLY THE STEERING COLUMN TO BREAK, RESULTING IN THE LOSS OF STEERING CONTROL, WHICH COULD RESULT IN A CRASH.

Remedy: NISSAN WILL INSPECT THE STRUT HOUSING AND REPAIR THE VEHICLES AS NECESSARY, FREE OF CHARGE. AN INTERIM NOTIFICATION LETTER WAS SENT OUT IN MAY 2011. THE SECOND NOTICE WAS MAILED ON JULY 25, 2011. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

Air Bags:frontal:driver Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

In their Defect Information Report (DIR) of April 20, 2011, Nissan North America, Inc. (Nissan) notified NHTSA that it would conduct a safety recall of certain 1996-2004 Nissan Pathfinder and 1997-2003 Infinity QX4 vehicles to repair corrosion damage to the driver's side front strut tower.The vehicles included in the recall are those that were originally sold, or are currently registered in salt belt states including Connecticut, Delaware, Iowa, Illinois, Indiana, Massachusetts, Maine, Maryland, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and the District of Columbia.The DIR states in part, ...the strut housing may crack and pull away from the inner hood ledge assembly.This could lead to the strut housing panel separating and contacting the steering column lower shaft.Contact with the steering column lower shaft can cause steering difficulties and may require an increase in steering effort by the driver.If the steering column lower shaft completely fractured it would result in a total loss of steering control.In some cases, the strut housing panel can contact or affect adjacent brake system components.Complainants reported experiencing either steering or brake system issues, and in some cases, both.Nissan dealer's will inspect the strut housing and, based on the level of corrosion found, make an assessment as to how to remedy the vehicle (see defect information report for additional details). Brake system components adjacent to, and in the area of, the strut tower (i.e., brake master cylinder, left front brake line, ABS wire harness, etc.) will also be inspected.
