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)

I purchased a Used Porsche Pre-Owned Certified 2019 Porsche Cayenne Turbo SUV on February 22, 2025, and within 4 to 6 weeks, the front brakes started to squeal very loudly when the vehicle comes to a near- stop. The dealership (Porsche River Oaks, 4007 Greenbriar Dr, Houston, TX 77098) tells me that this is normal squealing due to the type of brakes that this car has (PSCB). The squeal is louder than typical brake squealing and shouldn't appear on such a newly purchased certified car. I am reading multiple complaints on the internet about the squealing problems with the Porsche Surface Coated Brakes (PSCB) that I have on my vehicle. I am also seeing that. Porsche Cars North America, Inc has issued a Technical Service Bulletin 120/22ENU 4652 published on Sept 9, 2022, on how to fix this problem for its customers with a special brake disc and brake pad with better acoustical properties. The parts for this repair are extremely expensive. My car is supposed to be under warranty, but the service technician has offered to only clean the brake pads which the service advisor tells me should suppress the brake squeal for a short period of time, but then told me that the noise will come back due to the type of PCSB brakes this car has. I feel like I have been tricked into buy a car with defective squealing brakes and Porsche Cars of North America knew about the problem with these PSCB brakes. My worry is that Porsche Dealerships, know how to temporarily fix this squealing problem when they sell these vehicles by cleaning the brake pads.

SEVERAL TIMES A MONTH WHEN MY CAR COMES TO A STOP THE BRAKES MALFUNCTION AND THE BRAKE PEDAL GOES TO THE FLOOR AND THE POWER STEERING STOPS WORKING. IT TAKES UP TO ANOTHER CAR LENGTH TO FULLY STOP WHEN THIS HAPPENS - SOMETIMES JUST A FEW EXTRA FEET. IT HAS CAUSED ME TO DAMAGE THE FRONT END BY DRIVING INTO A BUSH. THE DEALER REFUSES TO DO ANYTHING BECAUSE THEY CAN'T REPLICATE THE BRAKE PROBLEM AND THEY STATE THE STEERING PROBLEM IS NORMAL. I HAVE BEEN ABLE TO REPLICATE THE STEERING PROBLEMS TO THEM BUT BECAUSE THE BRAKE ISSUE HAPPENS ONLY A FEW TIMES A MONTH I WAS NOT ABLE TO.
