Help!

I have a 2014 ZL1 unmodified automatic with ~6,000 miles.

This past Thursday, I took her out and the check engine light came on along with the Service Stabilitak indicator. Also, she was running very rough. I've had her out a few times this summer with no prior issues. The car is basically in mint condition.

I brought her into the local dealership for service. They got back to me and said that the Stabilitak issue was likely solved through a software update but they won't know till they put some miles on it.

They said that when they scanned the check engine light it was indicating that one of the cylinders wasn't firing properly. They said they swapped plugs and wires and it didn't help them diagnose the issue.

Their next step is to tear down the motor but they have several vehicles in front of me and can't get to it until next week the earliest.

I'm wondering what my options are at this point. I contacted another dealer and they are looking at roughly the same time frame, but their service center is much larger, and they have Corvette technicians in house so I'm thinking that may be a better place to bring it to. I would likely have to have it towed from one dealer to the other.
