Check Engine light came on and car was taken to the shop where it was diagnosed to have diagnostic codes PO302 and PO316 — at which time the mechanic informed me that the spark plug had ‘ceased’ and could not be removed — upon further research, found out that this is an issue with the 1.5L Ecoboost motor and that there was a program to replace but based on mileage/age, could not be replaced. The car is a 2018 Ford Escape SEL with 133k miles.
