2017 Porsche Macan GTS problems

What is wrong

Porsche Cars North America, Inc. (Porsche) is recalling certain 2017-2018 Macan, Macan Turbo Kits, Macan GTS, 2015-2018 Macan S, and Macan Turbo vehicles. The front passenger seat occupancy sensor mat may degrade and fail to detect a passenger in the front seat.

Risk

The air bag will not deploy during a crash if a front passenger is undetected, increasing the risk of injury.

Remedy

Porsche will notify owners, and dealers will replace the sensor mat and seat cushion, free of charge. Owner notification letters were mailed October 25, 2021. Owners may contact Porsche customer service at 1‑800‑767‑7243. Porsche's number for this recall is AMA2.

Recall number 21V131000 · Recall details

What is wrong

Porsche Cars North America, Inc. (Porsche) is recalling certain 2017 Porsche Cayenne Turbo S, Cayenne Turbo, Cayenne Plug-in Hybrid, Cayenne GTS, Cayenne Plug-in Hybrid Platinum Edition, Macan Turbo and Macan GTS vehicles, 2017-2018 Cayenne S, Macan, Cayenne Platinum Edition and Macan S vehicles and 2018 Cayenne vehicles equipped with the optional ski bag. The ski bag fastening strap may have been sewn with incorrect thread, possibly resulting in the strap seams tearing and the ski bag being unsecured in the event of a crash.

Risk

If the ski bag detaches during a crash, it can increase the risk of injury.

Remedy

Porsche will notify owners, and dealers will replace the ski bags, free of charge. The recall began January 10, 2019. Owners may contact Porsche customer service at 1‑800‑767‑7243. Porsche's number for this recall is AJ12.

Recall number 18V844000 · Recall details

What is wrong

Porsche Cars North America, Inc. (Porsche) is recalling certain 2015-2017 Macan S and Macan Turbo vehicles, and 2017 Macan, Macan Turbo with the Performance Package, and Macan GTS vehicles. The fuel pump flange on the affected vehicles may crack, allowing fuel to leak.

Risk

A fuel leak in the presence of an ignition source increases the risk of a fire.

Remedy

Porsche will notify owners, and dealers will inspect the flanges, replacing any that are cracked. Flanges that aren't cracked will have a protective film applied. These repairs will be performed free of charge. The recall began on July 19, 2017. Owners may contact Porsche customer service at 1‑800‑767‑7243. Porsche's number for this recall is AH06.

Recall number 17V289000 · Recall details

What is wrong

Porsche Cars North America, Inc. (Porsche) is recalling certain 2015-2016 Macan S and Macan Turbo and 2017 Macan GTS vehicles. The passenger occupant detection sensor mat may fail in the front passenger seat, deactivating the front passenger air bag. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk

In the event of a crash, if the front passenger air bag does not deploy as intended, the front passenger has an increased risk of injury.

Remedy

Porsche will notify owners, and dealers will replace the sensor mat and seat cushion, free of charge. The recall began June 28, 2017. Owners may contact Porsche customer service at 1‑800‑767‑7243. Porsche's number for this recall is AH02.

Recall number 17V133000 · Recall details

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 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 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
