I reported my steamed up headlight assemblies to NISSAN while performing oil change and tire rotations early on after my purchase which was 12302016 so end of year model clearance. The moisture in the headlamp affected night visibility. Felt safety concern but told the small weep hole was part of the product design. Why would any manufacturer put a weep hole on the headlamp if it is sealed w/ gaskets & engine compartment assembly sealed w/ gaskets at bulb/wiring harness? While driving in snow/rain, dirty water enters the assembly causing the temporary fogging affecting vision, especially after a warm day and moisture trying to escape via evaporation. ONLY PURE WATER CAN EVER EVAPORATE & DEBRIS DIRT left behind is impossible for owner to clean as this is CLOSED HEADLIGHT ASSEMBLY. Other complaint within a few years of ownership was the oxidation of the poor quality plastic used on the headlight assembly. I BOUGHT A CAR COVER to reduce sun damage once I had issues since this affects safety/driving visibility. I cannot drive w/ HIGH BEAMS in a CITY. I only have 55K miles as I have other vehicles that I drive & am very disappointed as I must now replace the entire two headlight assemblies BUT DO NOT WANT ANY M PRODUCT as I see their product as DEFFECTIVE and POOR DESIGN. MAJOR SAFETY CONCERN WITH VISIBILITY WHEN USING HEADLIGHTS which is OK if on due to rain during the daytime BUT NIGHT TIME VISIBILITY is TERRIBLE. Reported finally up the chain at NISSAN but want to report to your safety division. I cannot believe they were able to get away with this design FLAW & dismiss our concerns over safety for years. Told $2,000 for them to replace but I don’t want their DEFECTIVE HEADLIGHT ASSEMBLIES so now forced to research and purchase elsewhere with NO WEEP HOLE. All headlamps should be factory sealed and whver thought this was a way to avoid issues with poorly manufactured and sealed headlight steam complaints just made situation worse!
