From owners manual:
Roadside assistance will cover:
• a flat tire change with a good spare (except vehicles that have been
supplied with a tire inflation kit) WARNING: The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used. However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
So that means if you have a flat, with no spare, you're out of luck with Ford roadside repair.
Then if you do get it to seal, YOU have to pay money to get Ford to replace the valve stem and TPMS sensor because you used the tools they told you to use.
I've had two sidewall punctures in the last 2 1/2 years and I would not be caught dead without a spare.
