ELECTRICAL SYSTEM:INSTRUMENT PANEL:SPEEDOMETER/ODOMETER
Odometer Fraud. The contact purchased a 2021 Porsche Cayenne. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase on 5/29/25, the mileage was 21,000. The contact had taken the vehicle to another dealer for other repairs, and the dealer informed the contact that the vehicle was flagged for Odometer Fraud, and the actual mileage was 90,000. The dealer found an odometer tampering device still located on the vehicle, but deactivated the device. The contact called the State Attorney General's Office for New Jersey.

AIR BAGS
I am reporting a safety defect with my 2021 Porsche Cayenne GTS. The leather dashboard is delaminating and lifting away from its underlying structure. This defect is concerning because: The delamination is occurring on the drivers side but will eventually expand in the area covering the passenger-side airbag. If the airbag deploys, the raised/lifted dashboard material may interfere with or obstruct proper deployment, posing a serious risk to passenger safety. Porsche Cars North America (PNA) has been notified, but they classify this issue as “cosmetic” and refuse to repair it voluntarily under warranty or goodwill. Furthermore, The issue was not disclosed by the dealer at purchase. I have consulted two Porsche dealerships, both of which confirmed Porsche considers this a cosmetic defect not covered by the Certified Pre Owned warranty. However, given the location and potential interaction with the airbag system, I strongly believe this constitutes a safety-related defect that requires investigation. Online forums show this is a common issue across many models made by Porsche during this time but specifically SUV's. I am requesting that NHTSA investigate this issue to determine whether the delaminating dashboards in Porsche Cayenne models create a safety hazard that requires a recall and mandatory repair.

EXTERIOR LIGHTING
During rain events, headlight housings are becoming inundated with moisture (L and R sides). A quick search on multiple forums shows this is a known issue with all Porsche models. During night driving this issue reduces visibility significantly. Yes, this puts my occupants and other drivers at risk. Porsche is famous for not acknowledging and addressing out of warranty manufacturing defects, even safety issues. They would not address this issue. Brief warning lights and flashing of the headlight system was evident. This has been happening for a few years and is getting progressively worse.

VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
i was driving my car and at a stop sign i started accelerating when the light turned green - i must have been going 45 mPH after the light and all of a sudden my car went into hyper acceleration speeding up to 80 mph, i was pumping my brakes and the car was still raging to accelerate. I almost ran into a semi truck in front of me becuase i could not stop my car from accelerating, my foot was on the brake padel not the accelerator and it would slow down but as soon as I take the foot off of the brake - it would go into a rage accelration again, my car also gave WBA restricted warnings while accelerating. I was finally about 2 miles of stoping and accelerating pull into a sholder with my brakes slammed, and parking brake pulled, the car finally came to a stop. I was also being followed by other cars and could have caused them to run into me as i tried to stop the car.

AIR BAGS, UNKNOWN OR OTHER
The factory leather dashboard has detached/ungluded in places both on the driver and passenger side. Now the dashboard cover in the passenger area does not properly line up and has bubbled up on top of the passenger air bag door. There is a high possibility that this defect will prevent the passenger air bag from properly functioning or not function at all during an accident. Several Cayenne owners have reported this problem to Porsche USA however they will only replace at the owner's request and owners expense which is in the thousands of dollars. Porsche USA said that this is not a recall item therefore they will not pay for the repair.

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.

EXTERIOR LIGHTING
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.

FUEL/PROPULSION SYSTEM, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: WARNINGS
As I was making a turn onto another avenue, and accelerating to blend into traffic flow, dashboard messages suddenly appeared 1)"Engine control error, driving still possible, see dealer." 2)"Active lane keeping not available, driving still possible, service required" 3)"Adaptive Cruise Control not available, driving still possible, service required". Adaptive cruise was not engaged at the time of the error. The car lost almost all power, despite saying "driving still possible"; cars behind me had to brake hard as my car would only go about 7-10mph tops with accelerator firmly depressed and engine began to run very roughly. I coasted to shoulder of road, took video of error messages, turned car off and restarted car which cleared messages and car regained normal operation. I was glad this happened in-town and not when merging on a highway. This is not the first time the car has issued sudden warning messages stating certain systems had failed only to be cleared by restarting the car. I have taken the car to the dealer before to have them research the issue but they say errors cannot be replicated. However, this was the first time Engine control message posted and was the first time the car lost power and put me in danger of not being able to control the car's speed in traffic. I have lost faith in the car's control systems. I can live with lack of cruise control or lane keeping, but I cannot tolerate sudden lack of power than can cause an accident. This is my 3rd Cayenne, and unfortunately on this model, the electronics are ruining an otherwise well designed vehicle.

Dashboard leather is separating and was told this could affect the airbag deployment in the case of an accident. Porsche dealership is asking 10k outside of warranty to replace the dash. If it was just cosmetic I could deal with it, but now that it is a safety concern for my passenger I feel forced to overspend. Even a reduced amount would help but a whole dash replacement sounds excessive to make sure the leather is not obstructing the airbag.

ENGINE
There is a major issue with the coolant pump/water pump on the V8 4.0L engine. Every 30,000ish miles I’ve had to have a water pump replaced in my vehicle, Porsche NA claims they redesigned the pump and it fails in the same amount of time. Rennlist Porsche worldwide forums there are 28 threads of people having water pumps/coolant pumps replaced at the tune of $9,000-$12,000 because 70-80% of the front end of the Cayenne has to be removed to get to the water pump. The pump needs to be made out of more durable materials for durability and longevity. Expecting customers to replace water pumps every 30K miles is ridiculous. My 3rd water pump in 95K miles is being replaced as I type this right now. The dealership Porsche of Wallingford, CT, has 3 other customer Cayennes now that also need water pumps. Porsche USA and AG/Germany need to issue a 15 year/unlimited miles warranty on this water pump, like they’ve had to do with window switches, emissions valves, and other parts they have gotten sued for and now have 15 year warranties.

Posche dashboard leather coming apart at the staples. I was informed that if involved in an accident the airbags might not deploy. The Porsche dealer inspected and recommended replacing it. This issue has been on going with Porsche since it first began within the first few years of owning this brand new vehicle. I was informed that this is a very common issue, and a very serious safety issue with no recall issued as of yet. Please help us

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

SERVICE BRAKES
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.
