2 MONTHS AFTER MY WARRANTY ENDED MY TOUCH SCREEN WENT OUT. I TALK WITH MY SERVICE REPRESENTATIVE AT NORTHSIDE LEXUS AND HE TOLD ME UNFORTUNATELY THE ONLY RESOLUTION WAS TO REPLACE IT BUT IT WOULD COST 50% OF THE LABOR AND PARTS. I TOLD HIM THIS WAS A DEFECTIVE ITEM DUE TO THE SCREEN SUDDENLY WENT OUT WHILE I WAS STARTING THE CAR. FOR A 30K VEHICLE, YOU WOULD THINK THAT TOYOTA WOULD OWN UP TO THIS ISSUE AND THE OTHER ISSUE I COMPLAINED ON WITH THE MELTING OF THE INTERIOR DOORS AND DASHBOARD. I THOUGHT THE DEALERSHIP SINCE THEY HAD NUMEROUS COMPLAINTS WOULD BE LOYAL TO THEIR CUSTOMERS WOULD STEP IN AND SAY THEY WOULD TAKE CARE OF IT BUT SILLY ME WHO THOUGHT THERE IS STILL SOME LOYALTY IN THIS WORLD. MY FAMILY HAS BOUGHT 6 NEW LEXUS VEHICLES AND ALL WAS HAPPY UNTIL WE SLOWLY STARTED SEEING DIFFERENT ISSUES ARISE. I GUESS TOYOTA AND NORTHSIDE LEXUS DOESN'T MIND LOOSING LOYAL CUSTOMERS! *TR

MY NAVIGATION TOUCH SCREEN STOPPED WORKING ON MY IS250 WITH NORMAL CONSUMER OPERATION. I STARTED NOTICING HUNDREDS OF OTHER LEXUS VEHICLE OWNERS COMPLAINING ABOUT THE SAME ISSUE. THEY DID NOTHING TO CAUSE THIS ISSUE AND MAINTAIN THEIR CARS WELL. IN FACT, ALL THE SERVICE DONE ON MY CAR INCLUDING A RECENT UPDATE TO THE NAVIGATION SYSTEM DRIVING DIRECTIONS HAS BEEN DONE BY THE SAN DIEGO LEXUS DEALERSHIP. THEY HAVE BEEN SERVICING MY CAR SINCE I PURCHASED IT FROM THEM NEW IN 2008. IN MY RESEARCH I HAVE FOUND THAT THEIR IS A DEFECT IN THAT THERE IS A FAULTY CONNECTOR ON THE TOUCH PANEL. THE TOUCH PANEL IS A 4-WIRE RESISTIVE PANEL, TAPED TO THE LCD DISPLAY. THERE'S A FOUR WIRE RIBBON CABLE THAT IS IMPROPERLY BONDED TO THE TOUCH PANEL. LEXUS QUOTED ME $2,800 TO FIX THIS PROBLEM THAT IS A COMMON PROBLEM AND A DEFECT IN THEIR MANUFACTURING. IN MY OPINION LEXUS SHOULD TAKE RESPONSIBILITY FOR THIS ISSUE AS THEY PROVIDED FAULTY EQUIPMENT WITH HUNDREDS OF CONSUMERS HAVING THE SAME ISSUE WITH LEXUS. THE CONSUMER STATED THE DEALER RESOLVED THE PROBLEM. THE CONSUMER WOULD LIKE THE COMPLAINT, REMOVED FROM THE WEBSITE. UPDATED 07/10/13 *TR

19V741000 · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

Oct 17, 2019

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2010-2016 4Runner, 2003-2006 Tundra, 2003-2013 Corolla, 2009-2010 Corolla Matrix, 2004-2005 RAV4, 2002-2007 Sequoia, 2011-2013 Sienna, 2008-2012 Scion xB, 2008-2009 Lexus IS-F, 2007-2012 Yaris and Lexus ES350, 2010-2017 Lexus GX460, 2002-2010 Lexus SC430, 2006-2012 Lexus IS250 and IS350 and 2010-2015 Lexus IS250C and IS350C vehicles. These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and 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: Toyota will notify owners. Depending on the vehicle model, dealers will replace the front driver inflator, front passenger airbag inflator, the airbag assembly, or the front passenger airbag sub-assembly and inflator. The recall began November 20, 2019. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987. Toyota's numbers for this recall are J0A, J0B, and J0C.

EA21002 · 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.
