Most of the people I talk to with 2017's thru 2020's here in Michigan are seeing around 30 psi +/- 2 psi at hot idle. It seems like 2021's thru 2024's are seeing a bit more, 35-38 psi at hot idle.
They really dropped the ball on this oil pump situation.
I wish they would be more transparent about the root cause and what they did to address it.
Has your car been ok since the fix?

Yeah mine was starting to go out as I was starting to see it drop into the lower 20's at the time at hot idle. Luckily, at the time when I pulled it all apart, the pump internals were still visually inspecting out okay, so I didn't have to worry about shavings or glitter in the engine block so I still had a clean canvas to work with.

One factor which is not being spoken about here though is the oil viscosity being run. 5-30 oil will reflect different pressure than say 0-40 or 15-50. If you have a KNOWN GOOD oil pump, the pressure will reflect differently at idle. 35- 38 psi is questionable, but a thicker oil will cause a higher pressure readout than thinner. What is ultimately important is oil volume, not pressure. I'll take good volume over higher pressure anyday as the amount of oil passing through the system provides no sense of false security like pressure readouts do but unfortunately there is no quantifiable in dash method of reading/ tracking that.
