Ford Motor Company is adding 270,000 vehicles to a recall in North America, to fix a gearshift problem that could cause them to roll away unexpectedly.  The addition covers certain 2013 through 2016 Fusion midsize cars that have 2.5-leter engines.  The company is urging drivers to always use their parking brakes until the repairs are made.  Ford says a bushing that attaches the shifter cable to the transmission can degrade, causing the cable to detach.  If that would happen, a driver could shift into park, but the car could be in another gear.  Ford has one report of an injury and 3 property damage reports, with engineers developing a fix at this time.  Last year, there were 550,000 Fusions from 2013 to 2016 and Escape small SUVs from 2013 to 2014 for the same problem.  Ford says that owners will be notified when repairs and parts are ready, and that owners of cars fixed in the previous recall are not affected.  The 2018 recall covers cars that have a number of different engines, including the 2.5-liter.
