Ford Fixing Leak Problem With Software Upgrade Ford says that next week it will send dealers a software upgrade that will solve a fire concern that required the recall of 65,000 2013 Escapes and almost 15,800 2013 Ford Fusions in the United States. "That will resolve the issue," Raj Nair, Ford Group vice president, global product development, said in a telephone interview. The recalled vehicles have the 1.6 liter EcoBoost 4-cylinder engine. Escapes and Fusions with the 2-liter- and 2.5-liter engines are not affected. Ford recalled the vehicles last month, saying severe overheating and the leak of unidentified fluids could cause engine fires under the hood. Mr. Nair said the software change would assure the proper circulation of coolant and prevent severe overheating. He said that was causing fluids like oil, coolant or even gasoline to leak, causing fires if they came into contact with a hot engine component. The recall was the third time this year Ford has recalled vehicles with its 1.6-liter EcoBoost 4-cylinder engines for a fire hazard.
