The high-voltage battery pack in my 2018 Porsche Cayenne S E-Hybrid (VIN: [XXX] , approximately 81,000 miles) has experienced a noticeable and progressive reduction in battery range and performance. On February 20, 2026, Porsche White Plains (an authorized Porsche dealer) performed an inspection…
The high-voltage battery pack in my 2018 Porsche Cayenne S E-Hybrid (VIN: [XXX] , approximately 81,000 miles) has experienced a noticeable and progressive reduction in battery range and performance. On February 20, 2026, Porsche White Plains (an authorized Porsche dealer) performed an inspection but was unable to duplicate an active fault code and declined to generate a battery State of Health (SoH%) report. No warranty repair was authorized. Porsche Cars North America (PCNA), Case #XXX, has since moved to close my statutory warranty claim, citing the absence of a duplicated fault. However, under New York State's adopted CARB emission warranty standards (6 NYCRR § 218-9.1), high-voltage propulsion batteries in TZEV/PZEV vehicles are warranted for 10 years or 150,000 miles from the date of original sale. My vehicle was placed in service in 2018 and remains within that statutory coverage window through 2028. PCNA has not addressed this statutory obligation or provided written confirmation of coverage. I also have not received the inspection documentation I formally requested on March 17, 2026, despite no case closure having occurred at the time of that request. As of the date of this filing, PCNA has not responded to my follow-up correspondence. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Porsche Cayenne equipped with Michelin Tires, Tire Line: Latitude Sport, Tire Size: 295/35/R21, DOT Number: (N/A). The contact stated that while driving approximately 45 MPH, there was an abnormal sound coming from the front passenger’s side of the vehicle, and the front passenger’s side tire started deflating. The vehicle was driven to the side of the road and was later towed to the local dealer who determined that the front passenger’s side tire sidewall had blown out. The cause of the failure was not yet determined. The contact stated that the vehicle had not driven over any object to cause the failure. The tire manufacturer was not contacted. The vehicle manufacturer was not notified of the failure. The failure mileage was unknown.

This is not accident related, but what appears to be a systemic issue related to Cayenne and Macan leather dashboards. The issue is related to delamination of the leather dash cover that can impede the safe deployment of the passenger airbag. Many cars are affected and the repair can be a significant expense to owners (~$10K) for vehicles less than 8 years old. There should be a recall to address a largely unaware owner base for a potential safety issue.
- Air bags · Unknown or other
The Porsche Cayenne that equipped with leather dashboard are peeling off over the time. If the vehicle in an accident, the airbag on the passenger side dashboard may not deploy correctly. I am finding many cayenne owners are having this issue. I really hope NTSB can issue a recall.

While the vehicle was charging, the protective sheath near the power outlet of the charging cable had possible electrical or fire damage. No warning lights were illuminated. Upon turning off the power and unplugging the outlet, it was determined that the plastic near the plug melted and caused the power to short. I have been unsuccessful getting the manufacturer to resolve the issue. A recall under APB6 was issued but did not include model year 2018 which uses the same cable that is impacted with the recall.

Our 2018 Porsche Cayenne has a problem with the headlights and water intrusion that is affecting the functioning of the headlights. I took it to someone to look at and they said this should not be happening, that it is a manufacturer defect. I googled my car / year and there is a recall for headlight issues but for some reason my VIN is not included. It should be. How do I go about having Porsche North America fix this issue for me?

The day we took our Porsche home, we noticed a lot of heat generation in the car- but we thought it will be fine going further, given the attention to detail of Porsche's Automobile Engineering. The following days were not any better for my daughter- she missed a major accident because of the unexpected burnt smell and loud warnings of an overheat of the engine by Porsche in the middle of a highway. Due to her excellent driving record for the past 5 years, she was able to manage and stop in the middle of the highway at the curb of the road. She panicked so much so that, she stopped using the Porsche and borrowed our other cars, Benz and Lexus. I requested her to give Porsche another chance yesterday night. The same situation repeated again within a span of 10 minutes of her journey in Porsche; she had to stop in the middle of the road again due to engine overheat and burning smell and I went to pick her up as she got really scared. My son immediately informed the Hennessey Porsche North Atlanta, Georgia, the USA about this repeated situation but seems like they do not care at all. I think you must be aware that Dealerships play the most crucial role between your loyal customers and Porsche. We have not dared to take the Porsche out again after yesterday. The car smelled so burnt, the whole garage smelled bad and we had to move the car into the open driveway. THE CONSUMER STATED THE DEALER AND MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE DEALER ATTEMPTED TO REPAIR THE VEHICLE, BUT THE FAILURE PERSISTED. THE MANUFACTURER OFFERED $1000.00 IN COMPENSATION. THE CONSUMER REQUESTED TO BE REFUNDED TOTALLY FOR THE VEHICLE.

Intermittent lack of acceleration when taking left turns from a dead stop. car was a dealer loaner with 9000 miles on speedometer. I purchased the car in august, 2018. within the first 1000 miles and in less than four weeks I experienced a serious lack of acceleration on two occasions when making a left turn, I reported this to the dealer and was advised that it was probably driver error caused by operating the brake and accelerator using both feet. I do not drive an automatic car using two feet. also, I was told by the dealer they checked with porsche and there are records of this type of event. I checked on the internet and there are numerous identical complaints dating back several years. this lack of acceleration has occurred four more times. The dealer has been responsive and kept my vehicle on two occasions to try and duplicate the event to no avail. On one of these occasions the dealer replaced the transfer case but this did not solve the problem. finally, the dealer called in the porsche zone manage who I am told was well aware of this condition and referred to it as a safety feature to prevent unintended acceleration. He claimed that this IS perfectly normal operation. I call it a safety hazard. In four months I have driven the car 3200 miles. This so-called safety feature has engaged on only six occasions, always on left hand turns from a complete stop. When this happens I never know when the acceleration will cut out or how long I will not be able to accelerate. Up to now, the feature has never engaged in right hand turns, in forward or reverse. I have checked the owners manual carefully and there IS no mention of "unintended acceleration" nor IS there any mention of a safety feature programmed in the car. I have requested the dealer to by pass or eliminate this feature but thet say porsche won't allow it.

- Desiccated Air Bag Inflator Rupture
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…
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.
