Just a year and a half after the headgasket was replaced its running poorly again. Ford dealer told us its "Just spark plugs" and didn't say anything about why its loosing coolant and shaking hard. I do not understand how a car only has 56k and has had transmission problems and multiple engine problems when its been taken care of and drove normally, not driven hard. Lots of EcoBoost cars at the service center when we dropped the car off.
I bought a new 2018 Ford Mustang, it is all stock and is my daily driver. I have always done full synthetic oil changes and have done all the maintenance required. I don't drive it hard at all. Recently, I have began getting cold start misfires and codes P0300 and P0301 misfire of cylinder 2. Coolant has gone down and after using a pressure test and looking into the cylinders with a boroscope, there is coolant in cylinder 2 which is an indication of a blown head gasket or even block.
This seems to be a common issue with all other ecoboost engines and there's been a class action lawsuit that does not include the ecoboost Mustang, but it should because so many owners have experienced this same issue. All you have to do is look on youtube or ecoboost mustang forums where they have complained about cold start misfires and then coolant leaks beginning in cylinder 2 and needing a new engine or head gasket. It is not right that the original battery is outliving the engine and I will need to spend thousands for a head gasket and possibly new engine block. Ford should be held accountable for this and do a recall.
Car was purchased brand new, with the oil changed before 5 thousand miles, every time with full synthetic oil. Driven by a middle aged women so it was never driven hard. The engine started running rough when first started and progressively got worse. It started misfiring on multiple cylinders and dealer diagnosed it as a blown head gasket. The car runs significantly better after the head gasket replacement, but still runs rough.
