THE BACKEND WILL START CHANGING DIRECTIONS ON ITS OWN, THIS IS REFERRED TO AS GHOST WALKING BY SEVERAL OTHER PEOPLE POSTING ON THE INTERNET. FROM WHAT I UNDERSTAND IT IS A DESIGN PROBLEM THAT ALLOWS THE CAMBER ADJUSTMENT TO CHANGE WHEN WEIGHT IS ADDED TO THE REAR OF THE CAR. IT IS A REAL PROBLEM AND SOMEONE IS GOING TO GET KILLED.

THE CAR TURNED INTO THE OTHER LANE AND THEN CORRECTED ITSELF. THIS KEPT ON HAPPENING AT ALMOST EVERY OVERPASS WE WENT UNDER. SLOWING DOWN REDUCED THE DEGREE OF VEERING BUT WE KEPT EXPERIENCING THE WOBBLE EFFECT AS WE CROSSED UNDER EACH OVERPASS. ALMOST LIKE THE TRACTION CONTROL SYSTEM WAS "SLOW IN RESPONDING". TOOK TO THE DEALER BUT THEY REPORTED THAT THEY COULD NOT FIND ANY ISSUES WITH THE VEHICLE. DEALER SUGGESTED I BRING THE CAR IN AND HAVE A TECH RIDE WITH ME NEXT TIME THERE IS A SIMILAR WEATHER PATTERN.

MOON ROOF GLASS SHATTERED WITHOUT APPARENT CAUSE, WHILE DRIVING ON INTERSTATE HIGHWAY AT SPEED LIMIT IN GOOD WEATHER AND IN AN AREA WITHOUT TRAFFIC, OVERPASSES, TREES OR OTHER KNOWN HAZARDS TO GLASS. THOUGHT AT FIRST THAT I WAS MYSTERIOUSLY HIT BY ANOTHER VEHICLE FROM NOWHERE, BASED ON THE LOUD NOISE WHEN THE GLASS BROKE. FORTUNATELY, I WAS NOT IN HEAVY TRAFFIC, WHERE I MAY HAVE TAKEN EVASIVE ACTION TO AVOID ANOTHER APPARENT COLLISION. DEALER SAID THE NEEDED REPAIRS WERE NOT COVERED, SO I HAD THE WORK COMPLETED BY A LOCAL GLASS SHOP FOR $325 (RECEIPT IN MY FILES).

VEHICLE STARTING BECOMES SLOWER FOR ABOUT 1 WEEK AND THEN IT WILL NOT START AT ALL. I THEN GOT A BOOST FROM A SERVICE GARAGE IN THE FIRST INSTANCE AND DROVE THE CAR TO MY SELLING DEALER 40 KM. AWAY. THEY DID ALL THE TESTING, BATTERY, ALTERNATOR AND IT DID NOT SHOW ANY CODES. THEY ONLY DID DIAGNOSTIC WORK AND NO ACTUAL REPAIRS AND GAVE ME THE PRINT OUT JUST IN CASE IT HAPPENED WHILE WE WERE ON OUR 5 MONTH VACATION IN FLORIDA. THIS HAPPENED AT 25,000 KM ON THE ODOMETER IN SEPTEMBER OF 2017. IT IS NOW JANUARY 15, 2018 AND I AM IN FLORIDA. THE CAR HAS 33,000 KM. ON IT THE EXACT SAME THING HAPPENED, WITH A SLOW TO TURN OVER FOR ABOUT 1 WEEK AND THEN FAILURE TO START. I TESTED THE BATTERY WITH A LOAD TESTER AND IT TESTED AS "BAD" ON THE GUAGE. WE THEN BOOSTED IT TO START AND TESTED THE VOLTAGE FROM THE ALTERNATOR WHICH WAS 14 VOLTS AND THE BATTERY TESTED 12 VOLTS. AFTER A FEW MINUTES OF RUN TIME WE TURNED IT OFF AND IT FAILED TO START AGAIN. AFTER BOOSTING AGAIN I DROVE IT LESS THAN 1 MILE TO MY HOUSE AND LET IT RUN WHILE I CALLED THE ROADSIDE ASSIST AND GOT THE PHONE NUMBER OF THE NEAREST SUBARU DEALER, WHO INFORMED ME THAT ROADSIDE ASSIST WOULD BRING IT TO THE DEALERSHIP AND THEY WOULD TEST IT. IF THE BATTERY WAS BAD THEN THEY WOULD REPLACE IT. AFTER 15 MINUTES I RETURNED TO MY CAR IN THE DRIVEWAY AND TURNED IT OFF. I THEN ATTEMPTED TO START IT SEVERAL TIMES AND EVERY TIME IT STARTED CORRECTLY. MY WIFE THEN DROVE IT 15 KM. TO GET GROCERIES AND IT RESTARTED EVERY TIME THAT SHE LEFT THE STORES. I THEN DID ANOTHER LOAD TEST ON THE BATTERY AND THE NEEDLE NEVER WAVERED FROM THE GREEN AREA OF THE GUAGE. IT LEAVES YOU WONDERING WHEN YOU WILL BE STRANDED IN THE WILDERNESS OR THE SIDE OF AN INTERSTATE HIGHWAY. THANK YOU FOR ANY HELP THAT YOU MAY OFFER.

SUDDEN ACCELERATION: THIS SERIOUS UNSAFE CONDITION RELATES TO MY 2016 OUTBACK LIMITED 2.5L PURCHASED ON 2/29/2016 IN TAMPA FLORIDA. THE EXACT SAME UNSAFE CONDITION HAS HAPPENED TWICE; FIRST IN OCTOBER 2016 AT APPROXIMATELY 8800 MILES, AND SECOND IN DECEMBER 2017 AT APPROXIMATELY 24,000 MILES. DESCRIPTION OF INCIDENT: WHILE SLOWLY PULLING INTO A PARKING SPACE AND GENTLY APPLYING THE BRAKE, THE CAR'S ENGINE RPM ACCELERATED AND I HAD TO BREAK HARD IN ORDER TO STOP THE CAR. I MOVED THE TRANSMISSION TO PARK, BUT THE ENGINE CONTINUED AT HIGH RPM SO I MOVED THE TRANSMISSION TO REVERSE, THEN TO NEUTRAL, THEN I TURNED OFF THE CAR OFF SINCE THE ENGINE WAS STILL AT A HIGH RPM. A NOTICE APPEARED IN MY ODOMETER AREA TO PUT THE CAR IN PARK, WHICH I DID. I THEN RESTARTED IT AND EVERYTHING WAS BACK TO NORMAL AGAIN. NOTE: I DID NOT SIMULTANEOUSLY PUSH THE BREAK AND THE ACCELERATOR TOGETHER WHICH COULD POSSIBLY CAUSE THIS SITUATION. I AM FORTUNATE NOTHING WAS IN FRONT OF ME EITHER TIME. I HOPE NO ONE HAS BEEN INJURED, BUT IT IS LIKELY PROPERTY DAMAGE HAS RESULTED. PLEASE DETERMINE THE CAUSE AND CORRECT THIS POTENTIALLY DEADLY SITUATION. I AM TAKING MY CAR FOR A 24,000 MILE SERVICE ON 1/3/2017 AND WILL DOCUMENT THIS WITH THE DEALER (MASTRO SUBARU) AT THAT TIME. I SUSPECT THIS IS A COMPUTER GLITCH, AND A POTENTIALLY DANGEROUS ONE AT THAT. I ALSO SUSPECT OTHER CAR MANUFACTURERS CAN HAVE THIS SAME ISSUE IF THESE COMPUTERS AND PROGRAMMING ALL COME FROM THE SAME THIRD PARTY.

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.
