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

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 2017 Porsche Cayenne S E-hybrid verdict →
