general problems of the 2006 Mazda MAZDA6

The passenger side front vehicle frame has rusted completely through where the steering members attach. Found this when checking the brakes. Appears dangerous!.

I was sitting at a red light, my driver side door started to smoke. I was able to let it air out enough to drive home. As soon as I made it home, the smoke started pouring out of the window control and the whole door panel, rushed to get my kids out of the car. As the smoke thickened a fire started, I was able to put it out with a fire extinguisher before too much damage was caused.

I noticed the cooling fan coming on every time I turn the car on and it doesn't turn off for several minutes after the car is turned off. The engine is running in the normal temperature range, so I don't think the fan should be running constantly. I took the car to my mechanic, who notified me of a recall by Mazda for the fan control module for the same production year and the same make/model. I reached out to Mazda, but they notified me my VIN didn't fall in the range of the recall. It seems odd that the same product would have the same issue in the same car but not be covered by the recall. I wanted to notify the NHTSA of the issue in hopes that Mazda would resolve the issue. Thanks.
