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.

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)
