Huge problem
Last night shifting into 4th the car started misfiring the service engine light came on start flashing and I got all kinds of error messages as service stabiltack and service rear axle..
I ran a scan tool on it today it said cylinders 5 and 8 had a miss.. So we took the plug and the wire from 5 switched to 3 ran a scan again and still cylinder 5 and 8. I will get it towed tomorrow to the dealer but I was wondering if guy had any idea of what it could be.. Car only has 6,000 miles on it

But not Eco Mode so it wasn't transitioning to or from 4 cyl mode.
In any case, throwing a Service Rear Axle warning isn't uncommon if the torque applied to the diff isn't smooth (as would be the case of a bad misfire). So I don't think anything's going on with your diff, FWIW....

Valve spring? I've read many posts where the spring breaks and makes the engine sound likes it's going to explode.

Same thing just happened to me last night. Had it towed to the Dealer this morning. What was the outcome? I did not have a scan tool to read the codes. Called OnStar and they gave me a P0300 misfire. No specifics on which cylinders. Has to be more than one as it barely ran.

I had my 16 ZO6 with 2000 miles on it towed for a misfire.....spark plug wire fell off at the coil pack... tech said the clip in the wire was stretched out of shape... replaced the wire car fine...but still a pain in the *** and the mental trauma no fun when your new car ***** the bed ...

I hate having to deal with the dealer. Really do. Soonest they can look at it is freaking Tuesday! Then the service writer asks if I put diesel in it? I said, WHAT! No, how can you do that #1 as the nozzle wouldn't fit and #2 I have driven over 80 miles since I got gas. I am sure I would have noticed something before 80 miles. Probably a butt load of smoke too.

Sounds like a coil pack to me. Used to have all kinds of Coil pack issues on my old Caddy CTS, i got really good at replacing them. The Delco packs were c r a p and expensive. We'll have to see how these coils age but i would never replace with an OEM one again, especially if if fails prematurely and end up costing way more than they should.
