I RECENTLY PURCHASED PORSCHE CAYENNE S 2012 AND I'M HAPPY ABOUT THE SUV BUT THE COMFORT ENTRY FEATURE DOES NOT WORK ALL THE TIME SO I TOOK IT TO THE DEALER AND DEALER ALSO ACKNOWLEDGED THE PROBLEM BUT DIDN'T OFFER ANY SOLUTION. IT WORKS SOME TIME AND IT DOESN'T OTHER TIMES. WHEN YOU SET YOUR POSITION AND SAVE THE POSITION WHEN YOU UNLOCK THE DOOR WITH THE SAME KEY IT SUPPOSED SAVE ALL YOUR PREFERENCES LIKE SEAT,SIDE MIRRORS AND OTHERS BUT IT DOESN'T WORK MOSTLY...! I CHECKED IN FORUMS AND MOST OF THEM DO COMPLAIN OR THEY JUST GOT USED TO IT. I WOULD LIKE TO BRING IT TO YOUR ATTENTION WE PAID CLOSE TO $5000.00 TO THIS FEATURE AS AN OPTION. I REQUEST YOU TO INVESTIGATE ON THIS ISSUE AND IF YOU SEE A PROBLEM PLEASE ASK THE PORSCHE TO ADDRESS THE PROBLEM. *TR

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Porsche Cayenne Coupe S verdict →
