June 7-8, 2024 driving in rain, the #17- 25 amp headlight fuse blew, leaving my family and me stranded without headlights in the dark on I-70 highway. When headlights quit during this drive and it became Very Very dangerous! After getting the 2015 Cayenne home, I inspected both headlights. Driver's side headlight had a lot of moisture on the inside of lens. The passenger side headlight had about 1 cup of water inside headlight. Reading about Porsche Cayenne headlights leaking online, this issue should be a recall. I am going to take to dealership have them work on unrelated recall. I will ask them to inspect Cayenne. I can not drive this vehicle during inclimate weather or at night for an emergency or otherwise. I have been really busy at work and personally to take 60 miles to dealership. I have another vehicle I have been driving.

When I start the vehicle I get an error message that the rear lights are not working properly, but they are functioning well. This message is random and it can show up at anytime. I have contacted Porsche about this and they said that this is due to a faulty part that can be replaced, but requires 5000 USD. This problem was there when the vehicle was under warranty, but they never pursued or investigated it.

On August 21 2021, I was out shopping. When I went out to return home, the car would not start. I could not jump start it or anything. I had it towed to the dealer. I found out from Porsche and dealership that my car was disabled by Porsche Connect. I do not have this service or pay for it. On Friday Sept 3, I was informed by Porsche customer service that it disabled my car because the original owner (in 2015) changed their phone number. So Porsche assumed stolen and shut down. I did not authorize this, I did not sign up for this service. They will not fix the car because they say it is out of warranty. Because I do not know the code to turn the car back on, they want to replace parts and say I have to get the Porsche Connect App. This is a known issue at Porsche because the dealer found a TSB on it. They are not taking responsibility for shutting down the car with out my permission. This is a safety issue depending on where I could have been.

After the emissions recall was performed the vehicle has an issue that when turning a corner the engine will not produce any power and will not shift down in order to get the car to accelerate. You get no response from the throttle pedal unless you depress it fully to the floor and then the car will jerk and accelerate uncontrollably. This creates an unsafe condition when trying to pull out into traffic. I have almost been in an accident multiple times because of this with oncoming cars and with cars following me as they are trying to merge also and my vehicle will not accelerate. I have driven a vehicle identical to mine that has not had the emissions recall performed and it does not have this issue.
