2018 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 fiancé was driving the car normally on the elevated interstate at about 130 in the morning central time on Monday, April 20 when the suddenly burst into flames! The entire vehicle is destroyed bumper-to-bumper the fuel pump on these models are apparently reason for recalls because of this exact reason.my fiancé's life was endangered because of this fire.thank Goodness there was no collision.police inspected and towed the vehicle

Air bag light turns to "off" despite passenger sitting in seat. Took car to dealer (Bill Pearce Motors) who "verified customers concern" and "found fault present for passenger seat mat resistance to high" with a recommendation to replace "seat mat and module." This is at our expense (quote of $3700) and two trips to the dealer, being charged diagnostic fee each time. It is noted that a previous recall exists for this issue, however, it did not cover this vehicle. NHTSA ID 21V-131

I am writing to formally submit a safety complaint regarding my 2018 Porsche Macan. I have experienced a significant issue with the vehicle’s headlights, which I believe poses a serious safety risk. Description of the Issue: The headlights on my 2018 Porsche Macan have failed without any prior warning or indication. There were no dashboard alerts or error messages to notify me of a problem. The failure occurred suddenly while driving at night, resulting in a complete loss of forward illumination. This created a hazardous situation, as I was unable to see the road ahead and other drivers were unable to see my vehicle clearly. Safety Concerns: The headlight failure happened unexpectedly and without any warning. This issue significantly increases the risk of a crash, especially when driving at night or in low-visibility conditions. Upon inspection, I was told the entire headlight assembly would need to be replaced, which is costly and concerning for a relatively new vehicle. Request for Investigation: I am aware that other owners of the 2018 Porsche Macan have reported similar headlight failures. I urge NHTSA to investigate this matter, as it appears to be a widespread and potentially dangerous defect. Reliable headlight operation is essential for safe driving, and sudden failure without warning is unacceptable. Thank you for your attention to this matter. Please let me know if you require any additional information or documentation.

The Macan engine cooling system is defective and dangerous. It is made with a plastic cooling lines that are poorly placed (and concealed) where they are subject to high heat and pressure and therefore break suddenly. The danger is that it happens suddenly and you have to pull over right away even in dangerous road situations to avoid complete engine damage/failure. My husband and I drove the Macan to Mammoth Lakes for instance for the holidays and had to pull over in a dangerous side of a windy cliff, which posed great risk to our safety. Not to mention the difficulty and danger for a tow truck to access us. It was further pitch dark and snowing. We waited hours for the tow truck which thankfully came but we easily could have had to spend the night in a dangerous spot. Porsche should have let its customers know about this vulnerability so we could have changed these plastic lines even at our cost to avoid such a possible situation. They were sued for this same defect on the Cayenne. It's something I would have paid for and changed but they are not wanting to publicize this dangerous issue. They are putting customers' lives at risk. When we were (luckily) towed to Mammoth, Mammoth does not have the Porsche parts nor many mechanics so the mechanic (who was booked out for weeks) there did a temp fix and we risked our lives on the way back as well. We paid around $700 for the temporary repair and maybe another $1341 for the permanent change of the lines when we returned. This is a serious problem. We need to be able to trust otherwise reputable manufacturers like Porsche and our government entities. Happy to provide receipts. This vehicle needs to be recalled. At very least, the customers need to know about the issue because the plastic cooling tubes are concealed and not obvious. Further the lines cannot be replaced where the vehicle stalled and have to be towed to a mechanic.

Upon routine 80k service, discovered that steering wheel column loose due to faulty bushings. Individual bushings could be replaced but manufacturer insists that entire steering column needs replacement. Manufacturer should provide replacement bushings for technician to replace instead of entire column. This is simply an 8mm plastic piece!
