Problems with the Electrical System

Whether a luxury or budget-friendly car is being discussed, the electrical system should operate flawlessly. However, customers that spend this kind of money expect that there won’t be any defects.

This Edmunds review shows otherwise, “I’ve been back for multiple problems at least 12 times…4 times in service…they said there aren’t problems. Took to a Porsche specialist, hooked it up to computer system and most things failed. Now dealer handed it over to “Porsche”. They had it for 2 weeks…no phone calls or communication. It’s a lemon. For $104,000 I deserve a replacement. Climate (AC/heat) don’t work, seat memory doesn’t work, engine timing off etc.”

It turns out that there is also a recall due to defective equipment. NHTSA Campaign Number 19V111000 states that some vehicles have a software failure that is causing the rearview camera image to be delayed. Because of this, the driver doesn’t really know what’s behind the SUV, which could cause an accident. Now Lucy Liu might have said “You can’t look back; you have to keep looking forward,” but she clearly wasn’t talking about what to do while driving.

Problems with the Headlights

Seeing clearly is a main concern for people that drive at night, but defective headlights and systems make this cumbersome.

One example is found in this Edmunds review. “Auto Headlights do not work. I know at some point the Auto Headlight should work because I always drive the same road every morning and evening.”

It turns out, Porsche is very familiar with lighting issues. Even Service Bulletin #122-J5Q5U-01 talks about production errors that caused the tail lights to have visual defects. These defects include slight cracks at the edges and “significant cracks” as well. Who wants to spend this much money only to have a luxury SUV that looks like a baseball bat was taken to the lights?

Problems with the Brakes

Finally, the attention is turned to stopping the vehicle. Brakes are an essential component on any vehicle, but should work very well on one that costs this much. Yet, that’s not the case.

Read one more Edmunds review. “Squeaky brakes.  As another reviewer said, totally unacceptable in a 80-90k car. Worse, the dealers will tell you that it’s acceptable because it’s a race car and solution is to brake hard.”

There are even larger braking concerns. NHTSA Campaign Number 19V735000 states that 44,000 vehicles have a defective instrument cluster that doesn’t alert drivers as to when the brake pads are worn. Because of this defect, the vehicle might not respond as the driver expects, which increases the chance of an accident and injury. At this point, it might make more sense to stop the vehicle one last time while parking it at the junkyard.

Complaint Data

CategoryPower Train, Service Brakes

The vehicle lurches forward dangerously when coming to a complete stop. The brakes seem to release as the vehicle lurches forward.
CategoryElectrical System, Forward Collision Avoidance: Adaptive Cruise Control, Lane Departure: Assist
DateApr 28, 2022
There's an electrical issue with the vehicle (it is an e-hybrid) with error messages that run in a continuous loop (acc not available, pas restricted, driving light control error, high beam assist not available, lane keep assist restricted). The local dealer has not yet been able to fix the issue. Car is under warranty and has been in the shop for a month. We were called two times to pick up a "fixed vehicle" and each time we had to return the car almost immediately upon leaving the dealership since the problem was not fixed. I've contacted porsche customer service but as of yet there is no resolution. It is very concerning since some of these error messages do affect vehicle safety.
CategoryLane Departure: Blind Spot Detection
DateFeb 09, 2022
The contact owns a 2019 porsche cayenne. The contact stated that while operating the vehicle the blind spot monitoring system was inoperable and the message "blind spot monitoring not available" was displayed. The vehicle was taken to several different dealers who confirmed the failure was present but indicated that the failure could not be fixed. No further information was available. The manufacturer was also notified of the failure. The failure mileage was 60,000.
CategoryPower Train, Service Brakes
DateNov 08, 2021
When braking to a stop, the car lunges forward even when foot is on the brake. This occurs at slower speeds around 5mph right before a dead stop.

Yes the message reads:acc not available, driving permitted, service necessary. It first appeared on january 19 2020 still not resolved.
CategoryBack Over Prevention: Camera System
DateJul 18, 2021
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.

I looked it up and this is what happened previously reported by another owner. I had the exact same experience. Nhtsa id number: 11306756. *tr
CategoryElectrical System, Exterior Lighting, Vehicle Speed Control
DateFeb 03, 2020
There's a electrical issue with the vehicle. Periodically, these error messages run in a continues loop( acc not available, high beam assist not available, driving light control error, pas restricted and camera system restricted). The local dealers have not been able to fix the issue. I opened a porsche complaint file, which is number 5574318. This issue has been happening since the car was delivered, which was sixteen months ago. Porsche has made little effort in fixing the issue. It very concerning since when the error messages are rolling though it affects several safety features on the vehicle.
CategoryService Brakes, Steering
DateNov 27, 2019
Several times a month when my car comes to a stop the brakes malfunction and the brake pedal goes to the floor and the power steering stops working. It takes up to another car length to fully stop when this happens - sometimes just a few extra feet. It has caused me to damage the front end by driving into a bush. The dealer refuses to do anything because they can't replicate the brake problem and they state the steering problem is normal. I have been able to replicate the steering problems to them but because the brake issue happens only a few times a month I was not able to.
CategoryUnknown Or Other
DateMay 13, 2019
There is a strong smell of gas that happens intermittently while driving the automobile. This happens during slow motion in heavy traffic on both highway and local roads.
