Cabin filter OEM Toyota or OEM FORD

The why shupack answered, the fix if you care could be to try a third party cabin air filter. If there are any out there with a larger amount of carbon in them (carbon absorbs odor) that'd help. Replacing the cabin air filter behind the glove box is fairly easy to do and several YouTube videos on it. Cheaper than having the dealer do it, and 3rd party filters claim to be better. We did notice less smoke smell from the wildfires last summer when I swapped out from OEM to whatever filter I put in.

I change my oil+filter every 5k, engine+cabin filter every 15k, and CVT Drain and Fill every 60k (just once so far) and have not noticed anything weird or concerning.

I think it was my 80s bronco, like changing a cabin air filter. Undo hoses in engine bay, open glove box, open a door and slide it out and slide the new 1 in, attach hoses, close it up. Did it in less than 10min.

Bought a new set of tires, and a cabin filter. That's it.

Unexpectedly low maintenance costs (my cost just skyrocketed because I replaced my windshield wipers whereas to date in three years I'd only had to change the cabin air filter a few times).

Oh and there was evidence of a rodent’s nest in the cabin filter.

Be wary of Amazon, I ordered genuine Toyota cabin and engine air filters two years in a row, the second year the filter was noticeably lighter, cheaper feeling. I suspect a counterfeit imitation that has only half the filter material

I had them do a standard service on my Tacoma once. Oil, filters, etc. Next time around I had them give me a quote for a 150k mile service...and it was almost insulting. Got everything to do it myself for a fraction of the parts cost and when I went to replace my cabin air filter it was very clearly about 5 years old.

When I bought my 2005 Tundra I took it to Kendall Toyota for an inspection, they recommended a cabin air filter.

A 2005 Tundra doesn’t have a cabin air filter.
