ELECTRICAL SYSTEM, EXTERIOR LIGHTING
DURING NORMAL COMMUTE TO WORK DRIVING, A MESSAGE "CHECK DIM BEAM" APPEARED ON THE DASHBOARD MESSAGE BOARD. UPON ATTEMPTING TO CHANGE A FAULTY DIM BEAM HEADLAMP BULB, I FOUND HEADLAMP HARNESS WIRING AND ALL INTERNAL HEADLAMP ASSEMBLY WIRING IS CRACKED AND CRUMBLING AND CONDUCTORS ARE EXPOSED AND CAUSING SHORTS AND APPARENT LAMP FAILURE. OTHER HEADLAMP LIGHTING (SIDE DIRECTIONAL LAMP) LIGHTING FLASHED ON AND OFF WHEN HARNESS WAS TOUCHED, AND OTHER COMPONENTS OF ELECTRICAL SYSTEM FLASHED AND TURNED OFF AND ON BY THEMSELVES, PARTICULARLY THE RADIO. WHEN THE SUSPECT DIM BEAM LAMP WAS SWAPPED WITH OPPOSITE (PASSENGER SIDE, THE REPLACEMENT LAMP DID NOT WORK BUT THE SUSPECT LAMP FROM DRIVER SIDE WORKED ON THE PASSENGER SIDE LEADING ME TO BELIEVE THE LAMP ASSEMBLY WAS SUSPECT. UPON OPENING THE ACCESS POINTS ON THE DRIVERS SIDE ASSEMBLY, THE WIRING WAS SEEN TO BE CRUMBLING AND UNSAFE. I AM WORRIED THAT A FIRE MAY START AND HAVE DISCONTINUED USE OF THE VEHICLE AT THIS TIME.

EQUIPMENT
UNABLE TO LISTEN TO RADIO STATIONS ON RADIO DUE TO STATIC NOISE AND HEAVY SOUND INTERFERENCES EVEN ON LOCAL NJ FM RADIO STATIONS. THIS DEFECT SUBSTANTIALLY IMPAIRS THE USE, VALUE OR SAFETY OF THE VEHICLE, AS THIS IS CAUSING DRIVER FRUSTRATION AND REDUCED DRIVER FOCUS WHICH I AM AFRAID WILL LEAD TO A POTENTIAL ACCIDENT DUE TO NOT BEING ABLE TO LISTEN OR LISTEN WITH STATIC AND HEAVY SOUND INTERFERENCES TO THE RADIO FOR NEWS, MUSIC AND RADIO TALK. THIS HAS BEEN CONFIRMED AND TESTED BY AN INDEPENDENT AUDIO PROFESSIONAL IN WRITING AND REPORT CONCLUSION IS "RADIO STATIONS NOT WORKING CORRECTLY, HEAVY INTERFERENCES. TESTED ON LOCAL NJ STATIONS 94.3FM AND 101.5FM", *TR

I OWN A 2009 PORSCHE CARRERA CONVERTIBLE WITH PDK TRANSMISSION. IN STOP AND GO TRAFFIC AND CAR SHIFTS INTO NEUTRAL FOR A SPLIT SECOND OR TWO BEFORE ENGAGING INTO FIRST GEAR. MY CAR ONLY HAS 4,300 MILES AND THIS PROBLEM SEEMS TO BE GETTING WORSE AS TIME GOES ON. PORSCHE TOLD ME THAT THEY ARE AWARE OF THE PROBLEM WITH NO SOLUTION AT THIS TIME. THIS SITUATION IS VERY DANGEROUS WHEN I AM WAITING IN AN INTERSECTION WANTED TO MAKE A LEFT TURN AND THEN WHEN I FINALLY IT IS CLEAR TO TURN THE CAR WOULD SHIFT INTO NEUTRAL FOR ABOUT A SECOND BEFORE ENGAGING INTO FIRST GEAR. *TR
