Google: Cayenne wet floor. All Cayenne have issue with poor water drainage system according to the websites. My car was driving fine before I parked it, then when I try to start it, I got an error on the info display in red: ignition lock fault, abs brake proportioning. No crank from the battery, transmission locked in park. So I googled it and found many owners from around the world reporting this issue. The drainage under the windshield can get blocked easily with debris, and cause water to overflow inside the cabin and or electrical modules located in the windshield cowl area. On the driver side as per video, I removed the rubber carpet and forced lifted the permanent carpet, and found pool of water underneath, on the metal floor was a bunch of wires connecting to the car battery under the driver seat were all under water. I started emptying but more water kept coming, foams, rubbers were all soaked. According to the forums after removing all water, I needed to locate 3 set of wires amongst the bunch, these 3 are joined by twisting and wrapped with electrical tape/gauge from the factory. These wires since exposed are susceptible to corrosion. 1 set of wire completely snapped, apparently 1 wire is for abs brake, and the other is for ignition key lock that renders the car immobilized. I followed the video describing the steps to fix this issue myself, and big bold letters on videos to do not bring the car to the dealer as they will charge thousands, if modules need replacing, rust an owner recorded a video online of his Cayenne dash stop working, all lights blinking while the car was in motion. Luckily mine malfunctioned while parked at home, not driving with my family. I have 2 Cayenne, a 2005 and 2008 that my wife drives. I need to follow forum instruction in cleaning the drainage and removing the grommet that can be blocked and cause water not to drain.
Hybrid default multiple times in past years electrical system? fault generator check engine light.
Very scary and dangerous experience engine stalled after filling up with gas. The vehicle required two or three attempts to start. I exited the gas station onto the ramp for the interstate. The car suddenly locked up less than a mile down the interstate while driving 70, mph. There was no power braking or power steering at all. Fortunately, I remained in the far right lane and momentum carried the vehicle off the next exit ramp before vehicle completely shut off. I have had a host of other issues including psm failures, start/stop mode deactivated errors, ignition problems, braking issues, unnecessary repairs, time/energy, missed work, rental cars, misdiagnoses, etc. I am certain the symptoms are consistent with camshaft defect affecting many other Cayenne s, turbo, and panamera s owners per several internet forum discussions. This is really dangerous. I am disappointment earlier notifications were not issued and I hope this matter is addressed before someone dies.
While driving with both of my children in the rain my entire car locked and my windshield wipes stopped my windows wouldn't roll down and my doors locked on and off my alarm system started to go off uncontrollably even while driving Porsche isn't being of any help giving me run arounds also my check engine light came on in the process of the incident.
While leaving my home in my 2008 Porsche Cayenne turbo, the car started hesitating and then stalled out with a pdc error. After taking it in to the local Porsche dealership they reported finding nothing. The issue would occur 2 more times and I took it to a local mechanic specializing in Porsches who stated it was the throttle body. This was replaced however the issue is reoccurring with supplement errors such as chassis and check engine. My issue isn't uncommon please see provided links where others have had the same problems with their pdcc system. . Read more...
