My 2018 1.5 EcoBoost petrol Ford Kuga has been with the dealer for four weeks waiting for a new engine to be fitted under warranty. I reported it was using coolant with no visible signs of a leak. They said first said no fault was found and this amount of coolant loss is normal for Kuga. The engine failed shortly after this claim. I have suggested that, once they fit the new engine, the dealer can do the third year service and MoT - as both are due. The dealer says Ford insist on a full service even if it is a new engine and they will change me for new oil, spark plugs etc. They have also said this is likely as sometimes the engine arrives with this stuff missing. Shouldn't the new engine have new spark plugs and fluid? Why am I being charged for this service?
