The climate control systems recirculation feature works well but after about 15 minutes it just shuts off. Is that normal?

Thanks,

It is normal.

It is normal to allow for fresh air and oxygen to enter the car again and in so doing keep you alert

 

[Hatchman]

Yes, mine does this too. First car I've ever had that turns the recic off after a few minutes. Probably to let fresh air in, like said above.

Welcome, Arsene!

Not a good feature when on the freeway for hours. I am reminded with the terrible smell of diesel fumes and then have to reingage the circ.

Yep, normal. Diesel fumes may stink but they're remarkably not very dangerous.

Actually, the particulate matter in diesel fumes is bad for you, though your cabin filter may or may not trap these. But one of the reasons the recirculation turns off is that continuous use causes moisture build up in the system allowing biological things to grow which biological things and or their spores then circulate through the car, also bad for you.

There are fewer small particulates in diesel exhaust than in gasoline exhaust, but more large particulates in diesel exhaust. Those tend to fall to the ground quickly or get trapped by the cabin filter. The small particulates are the worst because they get deep into your lungs.
