Hello David,
Very likely because with do shell script, your script is running in a non-interactive shell.

You may try by detaching your sub shell:
cmdid=$$; (sleep 10;kill $cmdid) &>/dev/null & exec /usr/bin/curl -I "http://www.gm.com";
Anyway, I would try to avoid such constructs, especially when the command itself seems to provide the needed tools:
/usr/bin/curl --max-time 10 -I "http://www.gm.com";
HTH,
Axel
