2017 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.

My 2017 Porsche Macan has a Timing Chain Cover Bolt Failure which has caused leaking oil and may lead to total loss of oil and engine failure. This is a known documented design and manufacturing defect affecting the 3.0L and 3.6L engines. The manufacturers original aluminum bolts for the cover suffer from premature failure leading them to break. Porsche has recognized this widespread defect and problem by issuing a technical service bulletin for this issue. Porsche has not issued a recall to fix this problem. I have contacted a Porsche dealer to address this problem but they refused to make the repair without my paying the cost to repair their defect.

this is in regards to NHTSA TSB #ATI-1907. i had this issue repaired by porsche san antonio for over 1k. the problem came back and porsche is trying to charge me again saying there is a design flaw they are aware of but cannot perform work under warranty. This is very unfair and makes me think that everytime it rains i cant drive my car because ill have to spend another 1k for a rear camera and parking sensor fail. I hope i can get any kind of help or visibility on this problem. It is not only unsafe, but porsche as a brand has such bad customer service and no one wants to help

I am submitting this complaint regarding a known safety issue affecting my vehicle. I own a 2017 Porsche [2017 Macan GTS ], and I recently discovered that the fuel pump flange on my car has developed cracks, causing a noticeable fuel odor and potential fuel leakage. This component matches the description of the part listed under NHTSA Recall No. 17V-289 (Porsche Campaign AH06), which addresses the same defect. However, when I contacted Porsche and checked my VIN, I was informed that my vehicle is not included in the recall, despite exhibiting the exact failure described in the recall documentation. This situation raises serious safety concerns, as fuel leaks pose a significant fire hazard. I respectfully request that NHTSA investigate why vehicles experiencing the same defect are being excluded from the recall and ensure Porsche extends coverage to all affected vehicles. I am happy to provide photos, repair invoices, and inspection reports upon request. Thank you for your attention to this important safety matter. Recall Overview The recall campaign is identified as NHTSA Campaign No. 17V-289 (also known internally by Porsche as AH06). NHTSA +2 RepairPal.com +2 Affected vehicles: 2015-2017 Macan S and Macan Turbo, and 2017 Macan, Macan Turbo (with Performance Package), and Macan GTS. Asbury Auto +2 NHTSA +2 Issue: The fuel-pump filter-flange may develop fine hairline cracks due to aging/oxidation and internal pressure, which can allow fuel seepage. Fuel leakage in presence of an ignition source increases fire risk. NHTSA +1 Remedy: Dealers will inspect the flange. If cracked, it will be replaced. If not cracked, a protective film will be applied to the flange to prevent external damage. This work is free of charge. RepairPal.com +1 Date of notice: June 13, 2017 for this recall

Headlight severe crazing/crackle and DLR module failure. Both Porsche NA and extended warranty fail to cover or take responsibility for this poorly mfr’d part that is dangerous as it limits visibility as well as others seeing you. I want Porsche NA to own up to this hazardous parts failure.

Porsche is making use of aluminum fasteners for important engine components. These fasteners are substandard for the service. At 100,000 miles, two of the bolts for the timing chain cover simply broke in half during normal service, resulting in a substantial oil leak and an expensive repair (about $3000). At 120,000 miles, one of the bolts for the valve cover also simply broke in half, resulting in another oil leak and a repair bill of about $1000.

On [XXX] at around 6pm the AIRBAG light displayed in instrument cluster and remained steady after vehicle was placed in motion. I called my nearest service dealer at Porsche Carlsbad and they ran a vehicle diagnosis using their scanning tool. The finding was that the Front Passenger Seat Occupancy Sensor / Module was defective and needs replacement. The dealer also said that a recall had been issued (for which my vehicle's VIN was not listed). I called Porsche Company North America and they said my VIN was not part of that campaign to fix this issue, but I feel that this recall related to vehicle safety should have included my vehicle since it was within the make/model/year and trim of those included in the recall.
