Ford could be facing a £1billion legal bill over claims it put “life threatening” cars on UK roads when it let Ecoboost models leave its factories with a serious engine fault, The Sun reports.
The problem affects Fiesta, Focus, Kuga, S-Max, and C-Max models.
Drivers first reported low-mileage engines seizing up and even catching fire in 2013 but Ford refused to cover the repair bills on cars — and some families had to replace engines three times.
Law firm Roscoe Reid is acting for owners and estimates up to a million Ecoboost engines are on the roads.
Louise O’Riordan, the founder of a Facebook group set up for fed-up owners, said: “There are people all over the country who have experienced life threatening engine failure.”
Earlier this week, Ford said it notified 1.0-litre Focus owners of a “coolant hose potentially failing at high temperatures” in March 2015 and 86 per cent were fixed.
It added: “We seek to hear from the balance of owners.”
