There is more to the story than sitting for four days. That is not uncommon and does not adversely affect other brands of vehicles. Ford has been famous for decades for having sticking parking brake cables even on cars and trucks that are less than a year old. Many owners know to use the parking brake at least once every day or never at all.
When they first get sluggish and do not release, crawl underneath, (with it in park or the wheels blocked), and you will see the first half inch of the cable coming out of the outer casing is shiny indicating it has not retracted back to the released position. Flexing that outer casing vigorously with both hands will often help them retract under spring pressure. You may also be able to push the cable back into the casing by hand.
Lubricating a sticking cable is never the permanent fix. They must be replaced. Many aftermarket cables from the auto parts stores are less likely to develop sticking problems than replacements from the dealer.
If you do not see that shiny area on a cable that appears to be sticking, it may not be the cable. If banging on the backing plate as suggested frees it up, suspect grooves worn into the drum side of the backing plate. There are six raised surfaces called "lands" that the shoes ride on. Lack of a high-temperature brake grease when installing shoes can lead to grooves wearing in that the shoe frames catch on and stick applied. Some people try to file those grooves down but that can let the shoe sit at an angle and possibly chatter. The proper fix is to replace the backing plate and lube those six surfaces. That lube is usually overlooked by do-it-yourselfers.
