Seals around both headlights appear to be improperly/weakly sealed. Water intrusion is coming in from light rain or even a car wash causing entire headlight system to shut off until the moisture dries up often while driving. This vehicle has matrix adaptive led headlights and there is no self service bulb to replace since they’re leds. Local Porsche dealer service advisors appear to know this is a common issue but state Porsche has yet to do a recall and they have no fix option and only offer to sell me a full headlight assembly replacement.

MATRIX HEADLIGHTS DO NOT WORK, AT ALL. NIGHTTIME DRIVING IS DANGEROUS WITHOUT THESE HEADLIGHTS.

THERE'S A ELECTRICAL ISSUE WITH THE VEHICLE. PERIODICALLY, THESE ERROR MESSAGES RUN IN A CONTINUES LOOP( ACC NOT AVAILABLE, HIGH BEAM ASSIST NOT AVAILABLE, DRIVING LIGHT CONTROL ERROR, PAS RESTRICTED AND CAMERA SYSTEM RESTRICTED). THE LOCAL DEALERS HAVE NOT BEEN ABLE TO FIX THE ISSUE. I OPENED A PORSCHE COMPLAINT FILE, WHICH IS NUMBER 5574318. THIS ISSUE HAS BEEN HAPPENING SINCE THE CAR WAS DELIVERED, WHICH WAS SIXTEEN MONTHS AGO. PORSCHE HAS MADE LITTLE EFFORT IN FIXING THE ISSUE. IT VERY CONCERNING SINCE WHEN THE ERROR MESSAGES ARE ROLLING THOUGH IT AFFECTS SEVERAL SAFETY FEATURES ON THE VEHICLE.

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 2019 Porsche Cayenne verdict →
