My 2016 has been doing this also. Dealer checked all the grounds which now it seems to do it more frequently. Also the HUD is now bouncing. I'm out of warranty now so I hope someone finds the smoking gun to fix this issue.

I will say I was experiencing this issue after rebuilding my engine over the winter, was a loose ground on the block, passenger side, just under the header

Thanks for posting this. Took mine in to dealer today for another issue, and I quoted the TSB. Lo and behold tech supposedly found a painted ground. We shall see.

Old thread I know, but I had the issues with a bouncing tach and long crank before starting on my 18 ZLE. Got a CEL for P0340 and P0341 Camshaft position sensor. brought it in for warranty and the tech found that the harness had rubbed against something and rubbed through the insulation of a wire. They ended up replacing the Harness.

Mine was doing the same thing and I ran a new ground wire from the negative jump point in the front pass side to a solid spot on the engine. Can't remember where exactly I ran but it was close to a pulley under the evap cannister.
This 100% solved both problems of slow crank when hot and the tach jumping. If you need I can get a picture of it tonight.

Just to follow up: Today the car magically fixed itself. But what I mean by that is when I started it earlier the instrument panel actually had a short (but noticeable) delay before it came up. And then all of the sudden it was fine. Like perfectly fine. No more bouncing. I feel sure that it finally reset itself and in fact I could have probably got a dealer to do an update on the IPC and that would have cured it too. This all started after I hadn’t driven it for a while and the battery got low. It just took it this long (weeks) to straighten itself out. An amazing bunch of horseshit from GM in how they designed this particular system. Only problem I would have with the dealer reflashing the instrument cluster is I’m not crystal clear on whether they could do just the cluster without over-writing my tune. I THINK they could just from things I’ve seen but just don’t know as a matter of fact.
