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 the federal safety agency 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.

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 (the federal safety agency 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 (the federal safety agency 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 (the federal safety agency 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 (the federal safety agency MC-XXX) explicitly covers the V8 Biturbo variant and was not followed.
