SINCE THE CAR WAS NEW, PERIODICALLY WHEN THE VEHICLE IS STARTED,. THE BLIND SPOT CAUTION/WANING SYSTEM IS DISABLED. THIS IS CONFIRMED BY A CAUTION LIGHT IN THE INSTRUMENT PANEL. THE ONLY WAY TO REACTIVATE THE SYSTEM IS TO TURN OFF THE IGNITION AND RESTART THE ENGINE. IF THE MALFUNCTION IS NOT CAUGHT ON STARTING THE VEHICLE THE SYSTEM CANNOT BE ACTIVATED UNTIL THE VEHICLE IS STOPPED AND THE ENGINE RESTARTED. THE PROBLEM HAS BEEN ONGOING FOR TWO YEARS AND 40,000 MILES. EVERY TIME THE VEHICLE IS BROUGHT IN FOR SERVICE AT DARYL WALTRIP SUBARU IN FRANKLIN TN THE PROBLEM IS POINTED OUT TO THE SERVICE MANAGER. EVERY TIME I AM TOLD BY THE SERVICE REP THAT THERE IS NOTHING WRONG WITH THE SYSTEM BUT THEY HAVE UPDATED THE COMPUTER. RECENTLY A RELAY IN THE SYSTEM, PART NO. 87611AL00B, WAS REPLACED. THIS HAS ONLY EXACERBATED THE PROBLEM. I HAVE MADE MULTIPLE CALLS TO SUBARU'S CUSTOMER CARE LINE AND THEY HAVE NOT BEEN WILLING TO HELP. MULTIPLE CALLS TO THE SERVICE MANAGE AT DARYL WALTRIP SUBARU IN FRANKLIN TN HAVE GONE UNANSWERED AND HAVE NOT BEEN RETURNED. SUBARU CUSTOMER CARE HAS SUPPOSEDLY CONTACTED THE SERVICE MANAGER AT DARYL WALTRIP SUBARU REQUESTING THAT HE CONTACT ME, HE HAS NOT. THIS IS A CONTINUING PROBLEM.

OCTOBER 1, 2016 11:50AM, 32,00MILES SUDDEN UNINTENDED ACCELERATION (SUA) MY WIFE HAD AN ACCELERATION AND BRAKE MALFUNCTION ON THIS DATE AND TIME.SHE HAD JUST TURNED INTO A PARKING LOT AND ATTEMPTED TO TURN INTO A PARKING SPACE. AS SHE TOOK HER FOOT OFF THE ACCELERATOR AND APPLIED PRESSURE TO THE BRAKE, THE CAR ACCELERATED AND THE BRAKE WOULD NOT FUNCTION. THE CAR RAN OVER THE YELLOW CEMENT BARRIER AND WAS HEADING FOR A TREE, SHE CONTINUED TO APPLY PRESSURE TO THE BRAKE AND IT DID NOT RESPOND AS SHE TURNED THE CAR RIGHT TO MISS THE TREE. REALIZING SHE MAY BE HEADING FOR THE STREET SHE TURNED HARD RIGHT, STILL APPLYING PRESSURE TO A UNRESPONSIVE BRAKE PEDAL. SHE CONTINUED TO STEER HARD RIGHT TO MISS A FIRE HYDRANT. SHE LEFT TIRE MARKS IN THE BARK CHIPS NEAR THE HYDRANT. THE BRAKE FINALLY ENGAGED AND THE CAR CAME TO A STOP IN FRONT OF ANOTHER CEMENT PARKING BARRIER THAT WAS PERPENDICULAR TO THE STREET. SHE SAT FOR APPROXIMATELY A MINUTE, GATHERING HER THOUGHTS AND TALKING TO HER GRANDCHILD, IN THE BACK SEAT. SHE THEN DROVE SLOWLY OVER THE BARRIER AND PARKED. SHE DROVE AROUND THE PARKING LOT STOPPING AND STARTING BEFORE PROCEEDING HOME, APPROXIMATELY 2 MILES. THIS WAS A SUDDEN AND RANDOM ACCELERATION AND THE BRAKES WOULD NOT FUNCTION. WE BELIEVE IT HAS TO DO WITH THE COMPUTER THAT CONTROLS THROTTLE AND THAT IT MALFUNCTIONED. WE DO NOT FEE SAFE IN THIS CAR AND ARE CONCERNED THAT THIS SUA MIGHT HAPPEN AGAIN. WE ARE ASKING SUBARU TO REPLACE THIS CONTROL COMPUTER. IT IS AT THE DEALERSHIP WAITING ON THEIR EVALUATION. WE WANT TO DRIVE AND FEEL SAFE IN OUR 2015 SUBARU OUTBACK! THERE SHOULD BE NO DOUBT OR HESITATION IN KEEPING US SAFE AND ONE INCIDENT OF SUA/BRAKE MALFUNCTION IS ONE TOO MANY. WE HAVE PICTURES OF THE AREA SHOWING THE TREE, FIRE HYDRANT AND BARK CHIPS WITH TIRE MARKS. YOU CAN FOLLOW THE PATH OF THE VEHICLE THROUGH THE PICTURE.

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.
