Power steering groan

[emfollin]

I have a 2023 Silverado RST and have what I believe to be a power steering groan on initial take off. It only does it in my initial takeoff and only when the outside temperature is a bit cooler, say under 50 degrees. It didn’t do it all summer and now is doing it every morning. Anybody else experience this?

Its not the power steering.  Power steering has been electric since 2014, no hydraulics, no pump to whine.

 

Its probably engine oil pump or the transmission and are likely normal when cold.

Good point. I knew it was electric but didn’t think that all the way through.
