Rear axle, stabilitrack, CEL.

Took the car out today ('17 Z06 3k miles), noticed rough idle at first, then significant performance reduction followed by what felt like a wobble in the feel of the ride. Soon after that the CEL came on, stablitrack, and rear axle light, so I immediately took the car home. I do drive this car on a regular basis so it wouldn't be a issue of it sitting for long periods of time. Mechanic seems to think it is most likely a injector or coil issue. Has anybody experienced this?

Yes like 5 times. First time was a bad plug wire/plug when the car was nearly stock. Basically any time the car starts hard, I get those messages.

Had something similar when my battery was going bad. Replaced the battery and all was fine.

Try reading the DTC (diagnostic trouble codes) with a scanner.
Good starting point.
Go from there.

An engine code triggers the Stability and Rear Axle messages/codes since they depend on a properly operating engine to work properly. If there is anything indicating the engine can't control torque properly when another module requests a change in torque output the module requesting a change will shut down and set a code.

Yep just had the same issue on mine (15 Z06), ended up being the injector on cyl 4. We went ahead and replaced all 8, as well as new plugs, wires etc.
