On 7/13/21 afternoon, I parked my car in a parking garage of Purdue University, located in West Lafayette, IN. Around 6 pm, as I was backing out of my parking spot on reverse gear and turning the steering wheel, the car seemed sluggish. So, I pressed the accelerator -- lightly, I believe . All of a sudden, the car just took off, moving backward very fast in a semicircle. It first hit the back of a parked car with its front right side and then a concrete wall with its back with tremendous force. I was alone in the car. I called my wife. She came from our home and called 911. The university police and medic arrived promptly, as did two of our friends. One friend drove my wife and me to IU Health Hospital emergency in Lafayette, IN, and the other friend waited at the accident spot for AAA to come. Apparently, AAA came a little later and towed the car to Nissan of Lafayette body shop. Based on the x-rays and CT scans done at the emergency, the attending physician's assistant told me -- apparently, after consulting with a neurosurgeon -- that I suffered two fractures in a neck bone ("transverse process of cervical vertebra"). She gave me a hard collar and asked me to wear it 24 hours a day, expect when taking a shower, for 6 to 8 weeks. She also asked me to see a neurosurgeon, whom I will see on 7/26/21. The body shop person I spoke with next day told me that the car would likely be totaled (the car is still there). Since then, I have been thinking why the car moved so fast and also searching the web to find out any reason for it. Could it be an instance of the "sudden acceleration" problem? I must say that I have been driving Infiniti cars for many years. I have been very pleased with them so far, as well as the service provided by Infiniti dealers, especially my current one, Dreyer & Reinbold Infiniti of Indianapolis. I have decided to inform NHTSA of this accident so that no other person driving an Infiniti car meets with an accident like this.

I have a 2007 Infiniti M35S that has been garaged kept since purchase. My dashboard has started to crack and exude a shiny, sticky, messy substance. I do not know whether this substance is toxic to the touch or my respiratory system. I have never used any type of cleaner or solvents on my dashboard, only a microfiber towel and water. I'm not sure how to answer how my safety or the safety of others is at risk since I don't know what the particular substance is. Secondly does the fragile state of the dashboard put me and my passengers at greater risk of injury with the discharge of an airbag. I have read several complaints where other Infiniti owners are experiencing the same issue with Infiniti vehicles circa 2006 - 2008. Infiniti should do the right thing and fix this problem!!

I HAVE NOTICED MY DASH IS MELTING TERRIBLY BAD ITS NOW HAS SOFT SPOTS AND IS NOW SUPER STICKY FROM MELTING AND CRACKING AND CHIPING OFF IN SOME AREAS WHERE IT HAS MELTED AND THEN CRACKED AS IT HARDENED BACK. IF I TRY TO CLEAN IT WITH CLEANER MADE FOR DASHES THE COLOR JUST SMEARS AND THE DASH MATERIAL ITS SELF SMEARS AND ANY KIND OF CAR CLOTH JUST LEAVES PATCHES OF STUFF FROM THE DASH BEING STICKY AND MELTED. THIS HAS BEEN A COMMON PROBLEM I AM FINDING ALL OVER THE WEB. WHY ARE OUR DASHES NOT BEING FIXED? THIS CAN CAUSE MAJOR ISSUES IF I WAS TO GET INTO A WRECK AND THE DASH JUST CRUMBLES OR SQUISHES BECAUSE ITS MELTED.
MY DRIVE SHAFT BROKE WHILE I WAS ON THE HIGHWAY DRIVING AT 65MPH. THE DRIVE SHAFT THEN BANG A MASSIVE DENT IN THE ENGINE. 1200$ I WAS LUCKY ENOUGH TO BE ALIVE TO REPORT THIS
DASH HAS CRACKED IN NUMEROUS PLACES. THE CAR IS GARAGE KEPT AND I CLEAN THE DASH WITH A LIGHTLY DAMP RAG, NO PRODUCTS. IT BEGAN TO FEEL STICKY/TACKY BEFORE IT CRACKED. INFINITI IS DOING NOTHING TO RESOLVE THIS.

I HAVE CONTACTED THE NISSAN CONSUMERS AND FILED A REPORT APPROXIMATELY 2-MONTHS AGO AND WAS GIVEN AN INCIDENT NUMBER. I HAD COMPLAINED ABOUT SEVERAL CRACKS ON MY DASHBOARD IN MY 2007 INFINITI M35. MY VEHICLE OF LOW MILEAGE AND WELL MAINTAINED AND KEPT IN THE GARAGE. I HAVE NEVER UTILIZED ANY OTHER PRODUCTS ON THE DASHBOARDS. I HAVE BEEN REVIEWING SEVERAL POSTINGS BY OTHER CONSUMERS THAT HAVE BEEN DEALING WITH THE SAME ISSUE AND THE DEALERSHIP REFUSES TO INSTALL A NEW DASHBOARD DUE TO THE AGE OF THE VEHICLE. THIS IS A MALFUNCTION OF PRODUCTION ON NISSAN INFINITI PART AND ALL THOSE CONSUMERS AFFECTED SHOULD GET A FREE DASHBOARD REPLACEMENT FOR THE DEFECTIVE OF PART WHEN CAR WAS MADE INTO PRODUCTION. TO-DATE THERE'S A RECALL ON THE AIRBAG WHICH NO PART STILL HAS COME OR DELIVERED YET TO THE DEALERSHIP. I AM ADDRESSING MY GRAVE CONCERN AND HOPE THAT OTHER CONSUMERS WILL FILE A CLASS ACTION SUIT AGAIN THE NISSAN INFINITI FOR SELLING THESE CERTAIN KIND OF VEHICLES WITH DEFECTS AND DO NOT WANT TO HONOR THE REPLACEMENT OF DASHBOARDS THAT WERE IMPROPERLY PRODUCED BY THE MANUFACTURER. FOR A LUXURY CAR TO HAVE SUCH PROBLEMS THEN I AM VERY APPALLED DUE TO THE FACT THAT'S ALL I MOSTLY PURCHASE IS NISSAN VEHICLES. THIS MATTER NEEDS TO BE RECTIFIED WITH ALL CONSUMERS THAT ARE HAVING THE SAME ISSUE AS I AM WITH THIS PARTICULAR VEHICLE AND OTHER MODELS OF THE INFINITI ARE HAVING THE SAME OR SIMILAR PROBLEMS.
THE DASH IS CRACKING IN MULTIPLE PLACES AND IS STICKY TO THE TOUCH. INFINITI HAS NOT CHANGED THE AIR BAG YET AND HAS TOLD ME WHEN THEY DO THE DASH WILL PROBABLY BE IN WORSE SHAPE. THE CAR IS KEPT IN A GARAGE AT HOME AND A SUN SHIELD IS PUT IN THE WINDOW WHEN IT IS OUTSIDE. THE CAR HAS BEEN WELL MAINTAINED AND INFINITI DOES NO…

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.
