NHTSA Complaint #11468006 — 2013 HYUNDAI ELANTRA

In July 2015 with 25k miles, the interior of the vehicle was leaking water from the sun visor as well as under the glove box. When I made a left turn I could hear water swishing from one side to the other, then saw water coming out from under the glove box area. Water also dripped from the drivers sun visor. I took it to the dealer in Troy MI and they blamed me for having dirty drain holes in the sun roof as well as having a wind deflector on the sun roof which caused dirt to build up and clog the drain holes. The sun roof and wind deflector were factory installed as I bought the vehicle brand new in 2013. The dealer did not remove the headliner to see if any mold was visible. They used an air compressor to clean out the clogged drain holes and charged me for the service even though the vehicle was still under warranty (dealer said it was not covered under warranty). I am not aware of the issue happening again, or if it did happen it wasn't enough water for me to notice. I however have and do smell mold in my vehicle daily. Today, June 7, 2022, with 116k miles, after leaving my car parked outside overnight with heavy rain I again experienced water build up inside the car. I saw water coming out from under the glove box and heard it swishing around. I called the dealer in Troy MI and was told they cannot service my vehicle, it is a 4 month wait for diagnosis. I called a second dealer in Macomb MI and was told the vehicle could not be looked at until August and all expenses would be my responsibility. The service tech stated the car would need to be torn apart (dash, door, headliner, etc) to find where the water was coming from. A dealer in Southfield MI would be able to service the vehicle two days from now, I'm suppose to drive two days with water swishing around? What electrical safety issues are at hand here? It seems as though HYUNDAI has a defect in the design or part(s) which is causing this issue. I am also concerned with mold growth from back in 2015.
