| Exterior Lighting problems |
During rain events, headlight housings are becoming inundated with moisture (l and r sides). A quick search on multiple forums shows this is a known issue with all Porsche models. During night driving this issue reduces visibility significantly. Yes, this puts my occupants and other drivers at risk. Porsche is famous for not acknowledging and addressing out of warranty manufacturing defects, even safety issues. They would not address this issue. Brief warning lights and flashing of the headlight system was evident. This has been happening for a few years and is getting progressively worse.
The two headlights have appeared to have condensation due to sealing problem of the headlight. When the light bulbs and beam heat up the air with moisture, it will leave water inside of the headlight cover. This will increase the safety risks when we were driving on the road. There is no warning message for that. The problem should not be normal and this should really be manufacturer’s problem to fix.
The headlights aren’t sealed correctly so water has leaked in and caused them to malfunction. Porsche is making me get them repaired at a cost of $4100.
