VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
I applied the gas pedal & the pedal seemed to stick . The vehicle kept accelerating after I took my foot off that pedal to apply brake . Car would slow when brake applied but immediately accelerated and kept increasing (speed was well over 90 mph & climbing ) when brake was released . This happened 3 times before the “stuck”pedal released. Another driver (retired mechanic) had driven the car and had similar experience a week prior and mentioned their experience. I didn’t realize how serious the incident could be. I called dealership but first available service appointment (scheduled) is Feb. 23,2022

SERVICE BRAKES
when decelerating and car is in gear 2 it lurches the car forward while braking, basically fighting the attempt to slow the car down. I attribute this to aggressive downshifting, but is a safety issue because the operator then needs to compensate by pressing down on the brake pedal harder to stop the car. This has happened inconsistently when driving, but occurs more frequently than not.

FUEL/PROPULSION SYSTEM, POWER TRAIN, ENGINE
When slowing almost to a stop, and then need to accelerate, such as slowing for a yield sign, then trying to merge, vehicle is non responsive to throttle input for at least a second, or more. This has put me and others at risk because I assume I'm going to be able to accelerate when pull into traffic and am not able to. The dealer has had the vehicle but was unable to reproduce. It does not always do it, there's some combination of engine, drivetrain or fuel management it's in that does this. I have disabled start/stop mode. There are no system messages or OBD errors. The dealer has said that others have experienced this and the manufacturer has told them it's "normal". It's a safety problem and I'm seeking help in getting the manufacturer to fix it. Note, I sent the attached letter to manufacturer and did not receive a reply. I called their customer support line around Sept 20th and they did not offer any escalation or other action to address other than writing to their email address. I did this, and received no response.

UNKNOWN OR OTHER
On my Porsche Cayenne e-Hybrid model, the check engine light came on at less than 1000 miles. Porsche does not know why this happens but I've heard them claim that it's a software problem that has to do with how the car communicates with the charging system. Based on my research, there has been many other owners of the same vehicle with this problem. My vehicle has been in the shop for well over 30 days and Porsche still doesn't know what to do.

SERVICE BRAKES, POWER TRAIN
When the vehicle is decelerating and the transmission is in gear 2 the vehicle will lurch forward interfering/fighting with the normal operation of the brakes. This consistently happens when braking to a stop. The vehicle has 260 miles and I have driven it perhaps 4 - 5 times for a total of 30 miles. This is demo vehicle bought from a Porsche dealership and under full warranty.

ELECTRICAL SYSTEM
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.

ENGINE
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.

ENGINE, ELECTRICAL SYSTEM, UNKNOWN OR OTHER
The day we took our Porsche home, we noticed a lot of heat generation in the car- but we thought it will be fine going further, given the attention to detail of Porsche's Automobile Engineering. The following days were not any better for my daughter- she missed a major accident because of the unexpected burnt smell and loud warnings of an overheat of the engine by Porsche in the middle of a highway. Due to her excellent driving record for the past 5 years, she was able to manage and stop in the middle of the highway at the curb of the road. She panicked so much so that, she stopped using the Porsche and borrowed our other cars, Benz and Lexus. I requested her to give Porsche another chance yesterday night. The same situation repeated again within a span of 10 minutes of her journey in Porsche; she had to stop in the middle of the road again due to engine overheat and burning smell and I went to pick her up as she got really scared. My son immediately informed the Hennessey Porsche North Atlanta, Georgia, the USA about this repeated situation but seems like they do not care at all. I think you must be aware that Dealerships play the most crucial role between your loyal customers and Porsche. We have not dared to take the Porsche out again after yesterday. The car smelled so burnt, the whole garage smelled bad and we had to move the car into the open driveway. THE CONSUMER STATED THE DEALER AND MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE DEALER ATTEMPTED TO REPAIR THE VEHICLE, BUT THE FAILURE PERSISTED. THE MANUFACTURER OFFERED $1000.00 IN COMPENSATION. THE CONSUMER REQUESTED TO BE REFUNDED TOTALLY FOR THE VEHICLE.

BACK OVER PREVENTION: CAMERA SYSTEM
The back up cameras and surround view have failed multiple times since August 2020. Back up cameras were made mandatory safety equipment requirements for all new cars manufactured after 2018 due to safety concerns. The federal government mandated the cameras to prevent “back over” accidents of young children who are not otherwise visible to the driver. There have been multiple attempts to repair the cameras on this vehicle, including replacing all cameras, replacing all wiring harnesses/pigtails, replacing the coax cable for the cameras as well as module/software updates. The vehicle has been at the authorized service center multiple times with it being there 105 out of the past 112 days; the vehicle was "fixed" for 4 days before the back up camera failed again. The manufacture has been unable to repair the vehicle to have reliable working cameras. We have spoken with others about the same failure of the back up camera system.

BACK OVER PREVENTION: CAMERA SYSTEM
The surround video camera system frequently fails. One, several and sometimes all cameras randomly fail when triggered by placing transmission in reverse to park. Image is replaced by icon of camera with diagonal line through it. The dealer has attempted to fix this problem 4 times without success. They replaced all cameras and the video control unit. Many other owners of Porsche Cayenne, Macan and Taycans have reported this problem on various Porsche blogs. No one has reported a solution to the problem. The cameras are restored after turning off vehicle, leaving vehicle and locking vehicle. After waiting at least 15 minutes before rebooting vehicle, the cameras function normally. I have spoken to other Porsche dealers and none are aware of a solution to this problem. I have registered a complaint directly with Porsche and have not received any response in over 6 months.

UNKNOWN OR OTHER
I returned after being away for a few weeks, in May 2021. The solar panel had been on the inner windshield of the car following installation a few months prior. I found the car's 12V battery was almost dead (about 4 Volts), and the solar panel's plastic frame was severely melted, causing it to deform and lift away from the glass solar panel. Photos uploaded below. From reading reviews on this product on the Harbor Freight website, I now see that this is a common problem. I don't know what the cause is. Could be that the cheap plastic is just not made to withstand summer heat (although I have 2 more of these in my other cars, with no problems), and that the severe deformation of the frame somehow shorted something electical inside the panel that caused the car's 12V battery to discharge, heating the glass panel and melting all the surrounding plastic. Or it could be that an electrical problem was the trigger, causing the battery to discharge, etc. Harbor Freight is so far making it extremely difficult to try to raise the problem with them. I think this could be a serious issue, perhaps leading to a car fire. And if it is indeed an electrical fault that triggers this, then it could happen when parked in a garage (no solar heating needed), possibly leading to worse.
