2023 Mazda CX-50

Rain water leaking into interior body of vehicle. Water pools up between the headliner and interior body of vehicle. Mold starts to form on headliner fabric and in unseen places on the interior. Safety concern is mold. Living in warm humid tropical climates is asking for serious issues. Symptoms of mold: itching, coughing, wheezing, difficulty breathing, headache, and fatigue. A simple google search shows many owners coming forward online about the same issue happening in the exact location of each Mazda CX50. It’s too specific to ignore. This is being reproduced by dealerships and in other vehicles daily. (Look online, Reddit, Mazda forums.) The warning signs have been mold growing on fabric and water inside vehicle after rain. This is happening to 100s of CX50s.

I brought my car in to get it checked as the back drivers wheel was making clicking sounds when slowing down, both with and without breaks. I spent two weeks on my own trying to see what caused the car to make the sound when driving but was only able to learn that it makes the sound when slowing down, and disappears when driving at higher speeds. When brought in, the dealership was unable to tell me anything about the issue, as they were "unable to pinpoint it". After a few days, they were able to tell me that the issue is the differential, and that they would be unable to get the part. The differential is part of the axel, and is what allows the car to turn at different speeds. This is a serious issue and the car is less than a month and a half old with less than 1500 miles on it. The car itself is brand new, has never been used by anyone other than me and is having issues this quickly. The differential was inspected by the dealership, I am unsure if it was inspected by more than one person. But they are unsure as to when this issue would be getting fixed, and that car is my only transportation. The part has yet to be inspected by anyone other than the dealership. There were no warning lamps, signs, etc, only the sound of the back wheel clicking to show that there was an issue. Again, the car is less than a month and a half old, less than 1500 miles on it and this issue is incredibly dangerous.

At 10:16 am, I was driving home on Hall Rd. in Michigan. Hall Road is currently under construction and only two lanes are open and the speed is 40mph. It was raining pretty hard and also very windy. I was traveling West in the left lane and i noticed people in front of me began slowing down to about 10mph and going around an object I couldnt see. By the time it was my turn to pass said object, I realized it was a speed limit sign that had been knocked over by the wind. I went around it and pulled off to the side of the road where there was a small patch of flat, clear land (I believe there is a fire extinguisher or some kind of service system there). Try to act fast, I opened my door, removed my seatbelt and after looking for cars behind me, I ran across the road and picked up the large sign and moved it out of the way. By the time I had moved the sign, I noticed cars slowly approaching but were not willing to pass me. Then I heard them honking their horns but because it was raining hard, I couldnt see who or hear what they were saying. I figured Id look back at my car in case that was the reason and sure enough, it was and I jumped out of the way, and watched my car slowly fall off the ledge of the open roads and into the construction area of the new roads (there was a 2-3 foot deep and maybe 1-2 feet wide trench between the open road and the newly paved roads). My car then stopped abruptly, hanging over the ledge. Seeing the car had stopped completely, I opened the door and slowly got the car off the ledge. This did minor damage to the underside of my front and rear bumper but nothing serious. The problem I feel that is evident is that the car never engaged the electronic parking brake. This was a similar issue to what led to the death of [XXX] (granted, his shifting mechanism was an Audi style shifter and was shift-by-wire). I am not sure exactly what kind of automatic transmission is in my Mazda other than a 6spd. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B
