Porsche Complaints

2017 Porsche MACAN
  • Date of Incident: Nov-21, 2022
  • Date complaint filed: Nov-26, 2023
  • Failed components: STEERING

While driving east on i-40 in north carolina, my power steering catastrophically failed and i had to use all of my arm strength to steer the vehicle. The section of i-40 where this event occurred is extremely curvy (near the haywood rest area) and there is no margin for error. If i had not been alone and totally concentrating on my driving, i could envision a severe accident as there were cars all around me. I managed to drive the vehicle to my porsche dealer in columbia, sc for repairs. They found multiple faults for the steering torque sensors and determined that the electric steering rack was faulty. They replaced the steering rack. Prior to this event, i had complained to the porsche dealer about rubbing noises in the steering. The dealer replaced the steering shaft but the noise came back.

2016 Porsche CAYENNE
  • Date of Incident: Nov-26, 2023
  • Date complaint filed: Nov-26, 2023
  • Failed components: POWER TRAIN

While driving vehicle, noticed some slippage/clunking when turning. Took vehicle to porsche dealer, they said transfer case needed to be replaced. Car has 12,600 original miles on it. Dealer said there was an extended warranty on the transfer case that had expired. In researching, it became obvious that there is a porsche design problem that affected several model years for the cayenne. As a mechanical engineer i am concerned that a transfer case failure at freeway speeds could be dangerous. Separately an auto mechanic shop opined that driving without replacing could be a safety concern. In my opinion there should have been a recall rather than a extended warranty.

2022 Porsche TAYCAN
  • Date of Incident: Sep-05, 2023
  • Date complaint filed: Nov-23, 2023
  • Failed components: UNKNOWN OR OTHER

I was backing my porsche out of my garage with my foot on the brake. The car backed slowly as expected for a few seconds, then flashed a red display on the dashboard (see attachment) warning of an electric system error. It immediately self-accelerated in reverse at a high rate of speed across the street. The brakes did not work. Within 4-5 seconds it hit my neighbor's house and crashed into a room. I was trapped in the car and had to have the fire department get me out. The video police downloaded from the camera over my garage confirmed my account to them (as written above). I can provide the video if you would like to have it. A dmv examiner told me that about a year prior, around june 2022 an exactly similar accident was referred to him involving a porsche taycan accelerating out of control in reverse (see attachment).

2019 Porsche CAYENNE
  • Date of Incident: Nov-01, 2022
  • Date complaint filed: Nov-13, 2023
  • Failed components: ELECTRICAL SYSTEM

2019 porsche cayennes (and other porsche models) have life p04 lithium batteries that have an internal battery control module that causes a "battery low " indication. Porsche has been updating the software/ firmware for this module, only for it to fail again. Eventually, the battery will fail, lose charge, and become dead. There are no after market batteries available and if you are 1 mile out of the warranty period, porsche forces you to buy a new replacement battery from them for over $2,000. 00 usd plus labor. This battery failure condition for vehicles with this type of battery is well known by porsche and they now use a completely different type of battery in their newer models. This failure should be considered a safety issue and concern since the battery powers every safety feature the vehicle has to offer. There are pages upon pages of testimonies on the rennlist forum website for porsche owners and all have been advised to contact porsche cars north america and only a small percentage have had any luck with that. Porsche should release a recall to modify the system to the newer, more dependable battery for affected vehicles.

2017 Porsche MACAN
  • Date of Incident: Sep-26, 2023
  • Date complaint filed: Oct-23, 2023

The specific concern pertains to the routing of sunroof water drains from the roof to the wheel well of several porsche vehicles. In this case, the rear water drains are routed directly over fuses and other electronic components within the vehicle. One of the electronic components affected, a park assist control unit (part 95b 919 475 l), controls multiple vehicle safety functions including perimeter sensors and the backup camera. When this unit fails, the backup camera is blank and perimeter sensors that beep to notify the driver of potentially hidden objects (or people) close to the vehicle do not function. Such failure may jeopardize the overall safety of vehicle occupants and other road users and may affect safe operation of the vehicle. This park assist control unit has failed in my porsche macan on three separate occasions due to corrosion of the terminals. The porsche orland park (illinois) dealership where i took my vehicle for repair stated that the corrosion was due to leakage from the sunroof drain onto the unit. After the third failure of this unit due to corrosion, i contacted porsche north america customer support. I was told that the corrosion of the terminals and subsequent failure of the park assist control unit was due to clogging of the sunroof water drain, causing “pooling and draining to places where it can cause damage. ” although other electronic components directly adjacent to this unit have never had similar corrosion, there has never been evidence of water leakage inside the vehicle, and i regularly test the drains and have found no sign of blockages, i accepted porsche north america’s explanation. They stated that “park[ing] a vehicle outside” or “driv[ing] where there are many trees” may exacerbate the issue. Unfortunately, subsequent concerns i raised regarding the tendency for these drains to clog at any time and porsche’s decision to route a water drain in such close proximity to electronic vehicle safety systems were ignored.
