In owners' own words
Coolant intrusion into cylinder 2 at 26,000 miles. Was told by mechanic this is due to thin cylinder wall design between cylinder 2 and 3. And the thin coolant channel cut between them. A new engine block manufactured after 2020 was recommended because the engine design was changed to fix this issue. My warranty expired 4 months prior so I had to fix myself. Engine
Second oil pressure switch in less than three months. It is a pain to get to the oil pressure switch where it is located. The switch fails and shows that there is 130+ oil pressure. Freaks the computer out. Second switch in less than three months. Factory Ford switch GN1Z-90290-D 1X is the part number. Engine
