2016 Porsche Macan

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.

Y shaped plastic Coolant line cracks and leaks do to manufactures poor choice of materials! Resulting in engine overheating, and sever loss of coolant! Spraying entire engine compartment under hood white dried up coolant over spay spots with empty coolant reservoir and no heat. You would think that line would be made from an aluminum as it beads to with stand high heat temperatures from being against and engine.

Porsche dashboard leather shrunk and staples pulled out. I was told that if the vehicle was in an accident the airbag might not deploy correctly. The Porsche dealer said it needs replacing. This is a VERY COMMON issue and Porsche is not recalling to fix. Please investigate and make Porsche correct this serious issue. Thank You

Vehicle speeds up and breaks uncontrollably. When stopped it displays several codes on the dashboard 1) power steering fail, increased effort, driving permitted, 2) GRA/ACC fault driving permitted 3) faulty windshield wipers No fault codes are found with a code reader.

My Porsche Service Center advised that the front passenger airbag sensor of my 2016 Porsche Macan Turbo is not functioning properly. The identified fault was: Airbag (variant 002) B12251B "Seat occupancy sensor on passenger side (BOSE) - resistance too high" I have been advised that NHTSA has issued two recalls on this problem. My Porsche Service Center has advised that the originally installed passenger side occupancy sensor was replaced pursuant to one of the recalls. Despite the same problem affecting the presently installed passenger side occupancy sensor, my Porsche Service Center has advised that it is not subject to a recall. It has proposed repairing the sensor at a cost to me of $3,124.23. I believe that the repair should be conducted under the terms of the prior recalls, since the presently installed passenger side occupancy sensor is clearly defective.
