THIS CAR HAS AN UNDRIVABLE ISSUE OF TRAMLINING. IT IS SO HARD TO STEAR WHEN THERE ARE GROOVES OR ROAD IMPERFECTIONS...UNLIKE ANY OTHER VEHICLE I HAVE EVER DRIVEN. AN INFINITI MECHANIC TOLD ME THE PROBLEM IS A DEFECT IN DESIGN OF THE STEERING RACK. I CAN CHANGE THE STRUTS/SHOCKS AND PUT NEW TIRES AND THAT WILL NOT HELP...I HAVE BEEN TOLD. PLEASE FIX THIS PROBLEM SO I CAN SAFELY DRIVE MY CAR. IT IS SO JITTERY TO STEAR, I WILL NOT LET MY WIFE DRIVE IT. UPDATE: I SPENT $450 AT THE INFINITI DEALER TO TRY AND FIX THE STEERING. RESET A SENSOR AND ALIGNMENT. NOTHING CHANGED. CONSTANT TRAMLINING. I AM TOLD THAT A REDESIGNED STEERING COLUMN WOULD FIX THE ISSUE. AGAIN, THIS IS DANGEROUS. THE CAR WILL NOT STAY STRAIGHT ON A SMOOTH STRAIGHT ROAD. VERY DANGEROUS IN CORNERING.

I HAVE A 2007 INFINITI M35X AND HAVE NOTICED A PRONOUNCED PROBLEM THAT I RECENTLY LEARNED IS TERMED "TRAMLINING". I HAVE NOTICED THE PROBLEM MOSTLY AT HIGHWAY SPEEDS ON THE INTERSTATE. WHEN I CHANGE LANES, AS THE CAR MOVES TO THE CENTER OF THE LANE THAT I AM COMING FROM THERE IS A VERY DISTINCT PULL ON THE STEERING WHEEL AND FEEL AS THOUGH THE CAR IS COMING OUT OF A RUT. AS THE CAR COMPLETES THE MANEUVER TO THE ADJACENT LANE IT LITERALLY SWERVES ABRUPTLY INTO THE RUT IN THE NEW LANE, WHICH AGAIN PULLS THE STEERING WHEEL AND IS VERY DISTINCT. THIS PROBLEM IS AN ANNOYANCE DURING DRY AND CLEAR WEATHER CONDITIONS; HOWEVER, IN DEGRADED WEATHER SNOW, ICE, OR EVEN WET PAVEMENTS IT IS DOWNRIGHT SCARY AND IN MY OPINION PRESENTS A SIGNIFICANT SAFETY HAZARD. FROM WHAT I HAVE READ THIS IS NOT UNIQUE. I WAS RESEARCHING NEW TIRES (SUSPECTING THIS COULD BE THE CAUSE, ALONG WITH A GOOD ALIGNMENT). IN THE COURSE OF MY RESEARCH I FOUND OTHERS WITH THE SAME COMPLAINT. BY THE WAY, MY TIRES ARE NOT IN NEED OF REPLACEMENT AS YET AND THE ALIGNMENT WAS PERFORMED APPROXIMATELY 6 MONTHS AGO. I WOULD HOPE THAT WITH THE PROBLEMS TOYOTA WENT THROUGH RECENTLY THAT SOMEONE LOOKS INTO THIS PROBLEM BEFORE SOMEONE IS INJURED OR WORSE. *TR

Official recalls
4Jan 9, 2020
Nissan North America, Inc. (Nissan) is recalling certain 2001-2003 Maxima, 2002-2006 Sentra, 2002-2004 Pathfinder, 2007-2011 Versa Sedan and Versa Hatchback, 2001-2004 Infiniti I30 and I35, 2002-2003 Inifiniti QX4, 2003-2008 Infiniti FX35 and FX45 and 2006-2010 M35 and M45 vehicles. The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Consequence & remedy
Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the front passenger air bag inflators with alternate desiccated inflators, free of charge. The recall began February 12, 2020. Owners may contact Nissan customer service at 888-737-9511 or Infiniti customer service at 888-810-3715.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger 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.
