Ford will make software updates to the cooling system of the 1.6-litre EcoBoost engine in Norther American SE and SEL versions of the 2013 Escape and Fusion for which it recently announced a recall - for which no immediate fix was available.

The software updates will better manage engine temperatures during a unique overheating condition that could occur under unique operating conditions. The original cooling system design was not able to address a loss of coolant system pressure under certain operating conditions, which could lead to a vehicle fire while the engine was running, the automaker said in a statement.

From early next week (starting Monday 17 December), owners will be able to get the software update at their dealer. The time needed for the repair is under hald half a day.

But owners are still advised not to drive their cars and to contact a dealer to arrange alternative transport at no cost.

Some drivers who have experienced high engine temperatures followed by engine fires have said that their clusters have shown the message "engine power reduced to lower temps" or "engine over temp, stop safely." Some also indicated that their instrument clusters sounded a chime and illuminated a red light.

Ford continues to advise drivers who see any of these indications to pull off the road as soon as possible, turn off the engine and exit the vehicle.
