Looking for a little clarification on FEC.....

Would a HD or Digital FM radio receiver in a standard automobile employ a FEC decoder? The signal is digital (obviously) and FEC to my understanding would be applied to cases where there is a low tolerance for longer propagation i.e voice this case it is music/voice. Digital FM radio is simplex in nature and there is no channel back to the transmitter. Does this all sound reasonable? Non-RF folks at work were arguing, and my take was that it obviously would but then I couldn't justify it. I was under the impression that any digital signal would employ some sort of error correction or detection but was unsure if in this case it would indeed be FEC or another method.
