I have 2018 grand sport. The warm up temp halo. Not sure if that is the correct name of it come on and off randomly. Goes off then comes back on at the 5500 rpm spot. Any idea what could be going on.

Welcome to our forum. All C7s have a temporary reduced rpm halo that shows when the engine fluids are cold and gradually moves to the normal red line as the engine warms.

Really not sure what you mean by the halo. The redline on the tach is lower until the engine warms up. Is that what you mean? If not, can you take a photo and post it here?

Yes, that is what I was talking about. However, at the low temp of your engine, it should not be already over at 5500.

This was taken after the car was warmed up. Then it reappears at the 5500 rpm spot. Then it goes away and comes back.
Sorry, but your engine in that picture is definitely not warmed up. Your oil temp gauge in the picture is barely off the 100 degree F mark. It takes on average 15 to 20 minutes of driving before the fluids in the engine and trans are 'warmed' up.
