2019 Porsche Cayenne

Porsche has released a recall campaign but after taking my vehicle to a Porsche dealership to fix the recall, they informed me that they have not been given a remedy to the recall.

The AC evaporator failed at only 50,000 miles which is a manufacturer defect, as this part is not designed to fail and should withstand the life of the vehicle. When I wrote to Porsche regarding the failure, they tried to indicate or even suggest that this is normal wear and tear and the price of vehicle ownership. That is not a valid statement! This failure is considered premature and there is considerable documented evidence and concern widespread throughout the internet to back up this claim. It cost us almost $9000 to repair and almost a month of being in the shop. This is a significant repair and we actually took considerable time to not only research the issue, but quote the repair with other shops since Porsche wanted almost $15000 to conduct the repair. We would like this investigated as well as find out if there is any form of compensation we can seek due to the issue. Also, we were advised that the evaporator was leaking harmful chemicals through the vents of the ac, which cause mold and illness.

Perelli scorpion Verde tires started showing sidewall degradation and pitting in 2003 or earlier – the earliest photos we have are dated 2003. The tires had to be replaced due to the degradation and we requested the tire shop to look into a warranty claim. The tire shop changed hands and we went through four managers and weren’t able to get a clear answer, during that time the tires continued to get worse and pit. We found numerous reports on the Internet of the same tire having a identical issue and believe it is a material defect and safety issue of this tire.

The Waste Gate Arm has broken on my 2019 Cayenne. This is a widely known issue with Porsches. Feels like this needs a recall. It is absurd to me that the dealers want to replace the whole turbo unit at $7-9k when a simple weld can fix. I am 6 months out of the 7 year warranty but under the 70k mileage. I am pushing the dealer to work this out. But it is crazy that Porsche isn’t held accountable for a design flaw.

Complaint regarding a battery-monitoring/sensor issue, 2019 Porsche Cayenne and Porsche’s subsequent handling of the related repair. On May 22, 2023, at approximately 27,625 miles, my 2019 Porsche Cayenne was serviced by Fox Valley Porsche under Repair Order 103905. While driving a “battery charging warning.” showed, I was very scared. Dealer diagnosed a battery sensor failure and replaced the 12-volt battery. The invoice shows a battery charge of 1,957.87, plus labor. Repair documentation states “WMJ9 — Campaign not required.” I am asking NHTSA to investigate, whether the battery-sensor condition that resulted in my battery being replaced was related to the condition addressed by Porsche campaign WMJ9 and whether this condition can cause premature or unnecessary 12-volt battery replacement. Porsche subsequently identified the active fault associated with my vehicle as P1D6C00 and described it as a defect in the battery sensor located inside the battery. Porsche also stated that the vehicle’s battery-sensor software was already at software level 0164 and therefore the WMJ9 campaign was not performed. Porsche’s WMJ9 campaign addressed a battery-sensor/software condition involving incorrect battery-aging calculations and the potential for premature battery replacement. Because my vehicle had a battery-sensor fault and the dealer replaced the battery during the same general period that this campaign existed, I repeatedly asked Porsche and the dealer to establish why my battery itself required replacement rather than the condition being addressed through WMJ9. I requested objective documentation: • battery’s state of health/capacity at May 2023 repair; • battery test results; • diagnostic evidence physical battery failed, rather than only the battery sensor; • PIWIS diagnostic/scan information or other supporting diagnostic records; • basis for determining WMJ9 was unrelated Neither dealer, nor North America Porsche could provide factual test results.

The dashboard is peeling up and is unsafe due to airbag being underneath the leather dash. If airbag was to blow it would not function correctly due to dashboard leather peeling. Could potentially injur passenger or not deploy at all.

2019 Porsche Cayenne Turbo (EA825 4.0L V8, VIN [XXX]). Vacuum-actuated water pump seal failure caused coolant infiltration of the vacuum system on two separate occasions during the CPO warranty period. The vacuum system on this engine supplies the brake servo (brake booster) — a safety-critical connection documented in Porsche and Audi's own engineering literature for this engine (NHTSA document MC-XXX). First failure: XXX (92,916 miles, RO XXX). Towed in overheating. Technician documented coolant infiltrating vacuum system. Coolant pump replaced. Vacuum lines not inspected or replaced. Vacuum pump not inspected or replaced. PCNA's own ATI 2235.1 (NHTSA MC-XXX) required vacuum line inspection — not performed. Second failure: October 3, 2025 (103,904 miles, RO 207205). Coolant documented at timing chain cover. Coolant pump replaced. Change-over valve not replaced — required unconditionally by ATI 2235.1. Vacuum lines not inspected or replaced. No PQIS fault code logged — required by PCNA TSB 2307 (NHTSA MC-XXX). No oil analysis performed. No timing chain cavity inspection. Service visit performed one month before CPO expiration. Third visit: XXX (103,988 miles, RO XXX). Cracked breather hose found 84 miles after second service. Vacuum system still unremediated. Current failure: March 2026. Severe valvetrain noise on cylinder bank 2. Engine-out diagnosis required. Estimate $13,286.57. Vehicle currently at Porsche Novi/Farmington Hills. PCNA denied coverage June 25, 2026 without referencing a single technical bulletin, repair order, or published protocol from the documented record. The brake servo vacuum supply connection — documented in PCNA and Audi's own engineering literature — makes this a safety matter. PCNA's own TI 173/21 (NHTSA MC-XXX) explicitly covers the V8 Biturbo variant and was not followed. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The hybrid cooling system on my 2019 Porsche Cayenne E-Hybrid repeatedly displayed a red dashboard warning while the vehicle was in motion: "Hybrid coolant level too low / Park vehicle safely / Let vehicle cool down." This warning appeared on multiple occasions at speeds of approximately 22 mph, 38–40 mph, and 47 mph, as documented in timestamped photos and videos taken in November 2025. A separate warning in July 2025 read: "Engine cannot be started / Remove charger plug." The warnings indicate a potential thermal management or hybrid cooling system failure. A moving vehicle being instructed to park and cool down presents a safety risk to the driver and others, particularly if the condition causes sudden power loss or thermal event. The vehicle was serviced at an authorized Porsche dealer in 2025. Despite that service activity, the hybrid coolant warning recurred while driving in November 2025, suggesting the underlying condition was not fully resolved. The issue was reported to the manufacturer (PCNA), who acknowledged it under a case number and offered a service voucher. The selling dealer attributed the concerns to a manufacturer charging-cable campaign. Neither response addressed the recurring in-motion warning or confirmed the hybrid cooling system was repaired. Timestamped photo and video evidence is available showing the dashboard warnings and vehicle speed at time of occurrence. Complete repair orders have been requested but not yet provided. The component may be available for inspection upon request.

Porsche leather dashboard shrunk and staples pulled out. I was told if the vehicle was in an accident the airbag may not deploy properly. The Porsche dealer looked at it recommend that it be replaced. This is a known manufacturer defect that has been occurring with many of Porsche leather dashboards in different models. The manufacture is not taking responsibility in repairing or recalling this dangerous situation and putting the cost onto the customer. The fact that this is an option they offer as an additional cost on their vehicles , knowing this is a dangerous defect. This alone should automatically issue recall to fix before someone gets seriously injured.

The leather dash is peeling irregularly and will not deploy the passenger airbag properly if vehicle is involved in an accident and could result in death of a passenger. Serious problem with Cayenne SUV’s and Porsche refuses to address the problem with multiple complaints from other owners.

sudden total drivetrain failure at 52k mi with no warning, child passenger, prior dealer-documented leak that was not escalated.

At approximately 52,000 miles, the vehicle experienced a sudden catastrophic transmission / driveline failure while in use. The failure created serious concern about safe operation and reliability and left the vehicle disabled or unsafe to continue driving normally. An authorized Porsche dealer evaluated the vehicle and stated that the repair would require replacement of the entire transmission assembly at very high cost. No practical parts-level repair option has been provided. I am reporting this because a sudden major powertrain failure at this mileage may indicate a safety-related defect.

Bubbled dashboard is considered as a safety issue that airbag may NOT be properly deployed when an accident occurs.

SAFETY ASSESSMENT: 2019 Porsche Cayenne S Dashboard Material Failure Vehicle Identification: VIN [XXX] , Current Odometer: 46639 Assessment Date: 12/11/2025 Evaluator: [XXX] , Registered Owner/Operator ________________________________________ EXECUTIVE SUMMARY The dashboard upper assembly in this vehicle exhibits progressive adhesive delamination and synthetic leather separation (colloquially “bubbling”) across the instrument cluster housing and passenger airbag deployment zone. This defect, while initially cosmetic, presents measurable safety risks under Federal Motor Vehicle Safety Standards (FMVSS) by compromising passive restraint systems, driver visibility, and interior structural integrity during collision events. The failure pattern is consistent with documented manufacturing defects affecting 2018-2022 Cayenne production units. ________________________________________ TECHNICAL ANALYSIS Defect Manifestation: •Multi-point adhesive failure between dashboard substrate and synthetic leather wrap •Bubbles ranging 2-8cm diameter directly above passenger-side airbag module •Progression rate: 15% surface area increase over 4-month observation period •Material: Thermoplastic olefin (TPO) substrate with polyurethane coating exhibiting UV-degradation and outgassing Root Cause: Inadequate adhesive curing during manufacturing combined with incompatible material expansion coefficients, resulting in progressive de-lamination under thermal cycling. ________________________________________ SAFETY CONCERNS 1. PASSENGER AIRBAG DEPLOYMENT (FMVSS 208 Violation Risk) 2. DRIVER VISIBILITY IMPAIRMENT (FMVSS 101 Violation Risk) 3. INTERIOR STRUCTURAL INTEGRITY (FMVSS 201/214) 4. SECONDARY PROJECTILE HAZARD 5. OCCUPANT HEALTH & COGNITIVE LOAD This defect constitutes a latent safety hazard that degrades over time, not a static cosmetic issue. The combination of airbag deployment trajectory interference, driver visibility impairment, structural integrity compromise.

Porsche leather dashboard shrunk and is loose; I was told airbags may not deploy correctly. Porche recommended replacing the dashboard. This is a very common issue.

The dashboard material cover is pulling away lifting up from the dashboard where air bags are located.Not safe

While driving my 2019 Porsche Cayenne S on the freeway, the check-engine light came on, followed by a message on the dashboard that read “Engine Control fault – Driving permitted – Visit workshop.” Moments later, the vehicle suddenly lost power and decelerated from about ~75 mph to around 55 mph, even though my foot was still on the accelerator. I am [XXX] pregnant and had our [XXX] child in the car at the time. The unexpected loss of speed in fast-moving traffic was frightening. I had to quickly change lanes to reach the slower lane and avoid being hit by other vehicles. After reaching safety, I drove the car to an authorized Porsche dealership, where technicians found an active water-pump leak with coolant entering the vacuum system, which may have caused turbocharger and engine-power failure. This is after I replaced the water pump last year at another porsche dealership. A photo taken during the incident shows the dashboard warning message as it appeared. This incident created a serious safety hazard, as the vehicle displayed “driving permitted” even though it was at risk of a sudden loss of propulsion at highway speeds. The car and the failed components are available for inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
