I have a brand new Mazda CX-30 with less than 10k miles. I was not made aware of the seat material being highly flamible. Luckily I nor my kids were in the car when the seat caught fire due to a magnifying effect. Magnifying Effect (Sunlight): If a clear glass or plastic object (like a water bottle, eyeglasses, or even a certain type of air freshener) was left on the seat in direct sunlight, it could have acted as a lens, focusing the sun's rays onto a small area of the seat material. Over time, this concentrated heat could become intense enough to ignite the fabric, especially if it's dry and flammable. This is more likely to happen on a hot, sunny day. I brought this up with the dealership and their reply was to contact Mazda! YOU are Mazda!
