Ecoboost 3. 5l vehicle experienced total loss of power and white smoke from tailpipes while driving 65mph on expressway but still ran. Drove straight to an independent service center where they diagnosed low boost pressure dtc and failure of both turbochargers. Towed vehicle to Ford service center where they dug deeper and are now telling me there was a coolant system leak which washed out the engine oil and caused the engine to overheat and the turbos to fail(lock up). There have been numerous documented issues with coolant system leaks and oil supply to turbos causing failures/fire/overheating in ecoboost engines. . . Dealer is now telling me the entire engine needs to be replaced including the turbochargers in the ballpark of $13,000.
