2019 Volkswagen Tiguan

The windshield fluid washer disappeared aka consumed mystery without the operator usage. I had to fill in a gallon of the windshield washer every2-3 months, and I did not do any washing or anything to use the fluid. Last week, the check engine came in and told me to fill the washer fluid and it could not pump the washer fluid onto the windshield while I was driving the vehicle during the snow storm that blind me visibility on the road that could cause a very serious accident if that happened. This is a very serious safety issue that could kill someone. as of today, 12/27/2024 I just filled the windshield washer fluid and it consumed 3 gallons of the washer fluid. The question is where all the fluid went even that I did not use it?

MY CAR HAS HAD A WATER LEAK FROM THE PANORAMIC SUNROOF. I SAW THE WATER COMING IN FROM THE BACK PASSENGER SEATBELT HOLES ON BOTH SIDES OF THE CAR. I BROUGHT THE CAR IN TO GET FIXED, I WAS NEVER TOLDWHAT THE ISSUE WAS AND HAD TO ASK FOR OFFICIAL PAPERWORK. APPARENTLY THE SUNROOF DRAIN LINES WERE "KINKED AND CLOGGED." MY CAR WAS IN SERVICE 7/28/20-7/30/20 FOR THAT ISSUE. THERE WAS SIGNIFICANT MOLD GROWTH ON THE REAR FLOORBOARDS AND SMELLED OF MILDEW. I NOTICED SEVERE CONDENSATION ON ALL INTERIOR WINDOWS 8/4/20 AND MADE AN APPOINTMENT TO GET MY CAR LOOKED AT 8/6/20. I COULD NOT DRIVE THE CAR RIGHT AWAY SINCE I COULD NOT SEE OUT OF THE WINDOWS. I HAD TO PHYSICALLY DRY THEM WITH A TOWEL. I WAS THEN TOLD THEY COULD NOT FIND A LEAK, BUT THERE WAS STILL WATER ENTERING THE CAR AND THE FLOORBOARDS WERE WET. THE CAR HAS BEEN IN THE SHOP SINCE. ANOTHER CAR WAS IN SERVICE FOR THE SAME EXACT ISSUE WHILE I WAS THERE, I WITNESSED THE MOLD MYSELF. I RESEARCHED MY VIN AND THERE WAS NO RECALLS OR SERVICE BULLETINS FROM VW.
