Hi Phm. Another possibility...Have the PCM checked. Is your 2017 still within the 5 year/60,000 mile Powertrain Warranty?

 

Keep us updated and good luck.

Pressure test coolant system overnight then use a borescope to look at cylinder 2 if there’s coolant in the cylinder you have microfractures in the head
