2015 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.

Same passenger airbag issue as what everyone else is reporting! A recall is needed again for this!

My airbag light has remained on, uninterrupted, for over about one month now. I had the fault code read by an independent shop and they informed me that the fault was the occupant sensor for the passenger seat (BodySense front passenger seat occupancy sensor mat). They also informed me that this was the subject of a recall. Recall 17V-133/AMA2. I contacted a Porsche dealer as to the problem, made an appointment and took the car to the dealer. The dealer informed me that the recall on this part had already been completed. I expressed my concern that the recalled part obviously failed again, but the dealer indicated that corporate would not allow them to replace it again under the prior recall. I then filed a claim with Porsche NA. After weeks of back and forth with Porsche NA, they denied my claim, despite the fact that a previously recalled part had failed again. Performing some investigation since, I have learned that I am not alone and that the previously recalled Generation 1 seat occupancy sensor mat was replaced with a generation 2 mat, but that those were also failing. In fact, in January 2021 Porsche investigated this matter and did conduct another recall in February of 2021. However, for whatever reason my car was not part of that recall, though it suffers the same issue as to the failure of the Generation 2 mat. Any assistance you are able to provide is appreciated. Thank you. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear subframe of my 2015 Porsche Macan has suffered severe corrosion to the extent that it was no longer safe to operate the vehicle. This corrosion led to an unexpected failure of the subframe, causing the rear end of the vehicle to essentially collapse. As a result, significant damage occurred to both the control arms and the rear differential. A local independent repair shop specializing in German-made vehicles (Porsche, Audi, Mercedes, VW) assessed the subframe and confirmed that it was in extremely poor condition, having prematurely rotted and failed. Porsche offers a 12-year limited warranty against corrosion for body panels, but this warranty does not extend to the subframe. The cost of repairs to address the damage, performed by the independent shop, amounted to $3,600. It is worth noting that this issue is widely recognized among owners of 2015-2018 Porsche Macan and Audi Q5 models, as both vehicles share the same subframe. The problem appears to stem from a design flaw related to the inferior materials used in the construction of the subframe. Porsche is aware of this recurring issue, yet has not taken any corrective action to resolve it.

Coolant pipe burst or started a sudden leak and lost all the coolant while driving. I had to have the vehicle towed and repaired which costed me $2750. Porsche is aware of the problem but does not have a solution, until someone is killed when the vehicle stalls while driving.
