2017 Porsche 718 Boxster

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.

2017 PORSCHE BOXSTER 718 WITH PDK HAS STARTED IN 2ND GEAR ON 3 OCCASIONS MAKING ENTERING INTO TRAFFIC AT A SLOW RATE OF SPEED VERY DANGEROUS. 1ST TIME THE PDK TRANSMISSION WAS IN PARK AND THEN I MOVED IT TO DRIVE. THE PDK SELECTED GEAR 2 WHILE IN SPORT MODE. 2ND TIME I WAS BACKING OUT OF MY DRIVEWAY, STOPPED TO PUT IN DRIVE, AND THE PDK SELECTED 2ND GEAR. THE 3RD TIME I WAS SLOWING TO A LIGHT AND CAME TO A COMPLETE STOP AT RED LIGHT. I TOOK FOOT OFF BRAKE AND PDK SELECTED 2ND GEAR. I ATTEMPTED IN ALL CASES TO MANUALLY SHIFT INTO 1ST GEAR BUT THE PDK WOULD NOT SHIFT INTO 1ST GEAR. THIS HAPPENED ON 3 OCCASIONS FROM ABOUT JULY - SEP 2019. THIS PICTURE IS SHOWING THE 3RD TIME ON SEP 9, 2019.

WHILE DRIVING WITH MY WIFE AT APPROXIMATELY 20 MPH AFTER MAKING A RIGHT TURN IN THE LANE CLOSET TO THE CURB AT NIGHT WE HEARD A VERY LOUD BANG THAT SOUNDED LIKE A GUNSHOT. I PULLED OVER ABOUT TWO BLOCKS AWAY AND NOTICED MY PASSENGER SIDE MIRROR WAS DESTROYED AND THE COVER WAS MISSING AS WELL AS THE MIRROR. THE MIRROR WAS ROTATED INWARDS TOWARD THE PASSENGER WINDOW. WE CALLED THE HIGHWAY PATROL AND RETURNED TO WHERE WE HEARD THE EXPLOSION. ABOUT 20 MINUTES LATE THE SHERIFFS ARRIVED. WE FOUND THE MIRROR AND THE MISSING COVER ON THE SIDEWALK. GLASS FROM THE MIRROR WAS EMBEDDED IN THE PASSENGER WINDOW AND THE MIRROR HAD ROTATED INWARDS. WE WALKED THE STREET AND COULD NOT FIND ANY ROCKS OR ITEMS THAT COULD HAVE BEEN THROWN UP BY THE CAR. THE OUTSIDE OF THE MIRROR CASE HAS LITTLE OR NO DAMAGE, EXCEPT HITTING THE SIDEWALK. IT APPEARED THAT THE MIRROR HAD EXPLODED. I GOOGLED "EXPLODED PASSENGER MIRRORS" ON THE INTERNET AND FOUND THIS IS A MORE COMMON PROBLEM THAN EXPECTED MAINLY ON HEATED MIRRORS. I HAVE PICTURES OF THE SITE AS WELL AS THE MIRROR DAMAGE. SINCE I WAS IN THE LAND CLOSEST TO THE CURB IT WAS NOT POSSIBLE THAT ANOTHER CARE SIDESWIPED THE MIRROR. ALSO THE ONLY DAMAGE WAS TO THE MIRROR AND WHERE ITHE COVER HIT THE CAR.

REAR TIRES ARE COMPLETE BALD AFTER 5000 MILES. WE HAVE HAD CAR FOR OVER A YEAR. DEALERSHIP HAS INSPECTED AND VERIFIED ALIGNMENT IS FINE AND THERE ARE NO SIGNS OF AGGRESSIVE DRIVING. WHEN WE PURCHASED VEHICLE PARTS WERE MISSING FROM REAR TIRE AND WE HAD TO WAIT FOR THEM TO BE REPLACED. THE CAR IS NOT DRIVE ABLE AT HIS POINT. THEY ARE SAYING THAT WE SHOULDN'T HAVE DRIVEN BELOW 45 DEGREE. THIS IS MY WIFE'S EVERYDAY CAR BUT ANY SIGNS OF BAD WEATHER SHE TAKES A TRUCK TO WORK. THEY WAS NO MENTION WHEN WE PURCHASED THE CAR THAT THE TIRE WOULD SELF DESTRUCT AT 40 DEGREES. THERE IS NOTHING IN WRITING FROM THE DEALER OR TIRE MANUFACTURER STATING THIS. BOTH THE MANUFACTURER AND THE OWNERS MANUAL STATES THAT THEY RECOMMEND SNOW TIRES BELOW 45 BUT THE TIRES ARE NOT DAMAGED UNTIL 5 DEGREES. EVEN AT 5 DEGREES THE TIRE CRACK. I HAVE NOT BEEN ABLE TO USE THIS CAR FOR OVER A WEEK NOW WHILE THEY DECIDE WHAT TO DO. THE CAR IS NOT WITH THEM SO NOT SURE WHY IT WOULD TAKE THIS LONG. THERE IS NOTHING THAT STATES THE TIRES FALL APART BELOW 45 DEGREE. THE VEHICLE IS UNSAFE TO DRIVE, THE TIRES ARE SO SLICK THAT THERE IS NO TRACTION. I WAS INFORMED AT 2500 MILE TIRES SEEMED WORN BUT DEALER TOLD US THEY WERE HIGH PERFORMANCE TIRES AND IT IS OK, AND THE PERSON TELLING US DIDN;T UNDERSTAND PORSCHE HIGH PERFORMANCE TIRES.
