There are 4 owner-reported lighting complaints for the 2014 Porsche Cayennein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Last week I took my car to car wash, After that my right passenger side light went off. water went in the rear sound control module and I lost sound too. my gps sound comes from woofer only. I heard from a by other Porsche owners that porsche had recall on rear lights, But I was never informed.
The contact owns a 2014 Porsche Cayenne. The contact stated while driving at an undisclosed speed while depressing the brake pedal, the brake lights became inoperable. Another motorist informed him that the brake lights were inoperable. The contact continued to drive with the hazard lights activated. The contact noticed that the plastic plugs were clogged with leaves and dirt and water had entered the vehicle which short-circuited the electrical system. The vehicle was taken to an independent mechanic who stated that the sunroof plastic plugs were broken, and that water had entered the vehicle. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 75,600.
After going through the car wash, I lost my rear brake lights and rear running lights. Still have the third brake light. From reading on many Porsche form sites, this is a common issue. The vehicle does not have adequate drains, in return, water leaks into multiple areas of the vehicle causing electrical shortages. You do not get any warning bells, or signs on the dash that you do not have rear taillights. It is a very dangerous issue.
I PURCHASED A 2014 PORSCHE CAYENNE DIESEL NEW IN AUGUST 2014 EQUIPPED WITH THE CONVENIENCE PACKAGE WHICH INCLUDES BI XENON HEADLIGHTS WITH "PORSCHE DYNAMIC LIGHTING SYSTEM" (PDLS). THE PDLS IS QUITE COMPLICATED AND HAS SOME GOOD FEATURES BUT IT DOES NOT ILLUMINATE DOWN THE ROAD VERY FAR AND IS DANGEROUS ON HILLY TERRAIN. SOMETHING IN THE SYSTEM MAKES THE TOP OF THE BEAM SHUT OFF SHARPLY SO IF YOU APPROACH A HILL YOU CAN NOT SEE BEYOND THE BASE OF THE HILL. EVEN REFLECTIVE SURFACES ARE NOT ILLUMINATED. I DO A LOT OF DRIVING ON HILLY TERRAIN WITH A LOT OF WILDLIFE. THIS IS A DANGEROUS SITUATION. I HAVE WRITTEN THIS UP ON EACH OF 4 VISITS TO THE PORSCHE DEALER AND THEY SAY UNTIL PORSCHE COMES UP WITH A FIX, THERE IS NOTHING THEY CAN DO. PORSCHE REFUSES TO DO ANYTHING ABOUT IT.
