NHTSA Complaint #11654003 — 2019 PORSCHE CAYENNE

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.
