Cayenne

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)

Porsche dashboard leather shrunk and staples pulled out, I was told that if the vehicle was in an accident the air bags might not deploy properly . the Porsche dealer looked at it and recommended replacing it . this is a very common issue .

leather dashboard bubbles up and could effect the deployment of the passenger airbag

The leather dashboard has shrunk to the point where the the Porsche dealer recommend replaceing it. This appears to be an issue serious enough to prevent the airbag from deploying correctly if in an accident. This appears to be a common issue.

Seals around both headlights appear to be improperly/weakly sealed. Water intrusion is coming in from light rain or even a car wash causing entire headlight system to shut off until the moisture dries up often while driving. This vehicle has matrix adaptive led headlights and there is no self service bulb to replace since they’re leds. Local Porsche dealer service advisors appear to know this is a common issue but state Porsche has yet to do a recall and they have no fix option and only offer to sell me a full headlight assembly replacement.

the dashboard has a fitted leather coating covering the airbag... the leather and its surrounding seals has melted.. almost entirely.. and it is rippled and uneven all around... this is widespread for these models and may cause problems with the airbag in the dash...the airbag has to be able to deploy without any problems.. the dash should be fixed so it is safe

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.

The A/C in this 5 year old vehicle no longer works. There are no warning lights or anything to suggest the A/C is no longer functioning, other than turning it on to see if it works. The weather would need to be warm enough to test it. The dealer said it is due to the Evaporator core, and to replace it would cost $8,000.00. Upon search, many others have had this same malfunction. Audi uses the same part in their vehicles and in 2021, they revised their new car warranty to include the A/C evaporator for 10 years/100k miles. Porsche should also commit to this action as they are using the exact same faulty part and these vehicles cost even more than the Audi’s.
