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.
Taillights getting condensation.
I looked it up and this is what happened previously reported by another owner. I had the exact same experirnce. Nhtsa id number: 11306756.
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.
