Refurbished M4 MBA Kernel Panic - iBoot Panic, Unexpected SoC (system) watchdog reset

I personally recommend that you return that Mac for a full cash refund forthwith. Buy another one. Don't even think about it. You don't even have to tell them why.

Very frequently, the result of a hands-on inspection by Apple results in "can't find anything wrong, must be you" followed by more crashes once you get it back. Or, they might repair it and in all likelihood it will work flawlessly for years to come. Meanwhile, your fourteen day "no questions asked" return window is closing.

This isn't your problem. Make it Apple's problem.

Thank you for keeping us all posted

Agree with your choice to return for a Refund

As others have mentioned - Make this an Apple Problem not your problem

I second John Galts recommendation.

Your reports suggest you have a very complex issue with the System-on-a-chip and the Genius Bar technicians are generally Not trained to read those panic reports.

NB>>

The one downside of the Apple refurbished store is that you can NOT take the 14-day return/exchange for NEW at the Apple (bricks and mortar) Store.

Your recourse is to notify the refurbished store and return the device to the refurbished store, ONLY.

I see nothing on the Supplied Report ( Thank you for having been Proactive 👍 ) that would account for this issue

Be sure to make a Backup of the drive Before moving over to the Genius Bar appointment for tomorrow.

The may insist on redoing what you have already done " Erase all Contents and Setting " and good work there too

Once that is done and depending on the outcome

They may do additional Testing using their  Special Hardware Software and Expertise to diagnose the issue 

Good luck and if time permits

Do keep us all posted on the outcome

You are very welcome

Having purchased Refurb Laptops exclusive from Apple

Generally and in personal experiences

They have been as good as the time they came off the assembly line

Though as were are all humans lol

Something may have snuck through at the other end

Unfortunately for you, you may have one of these at Snuck Through, machines

Fortunately they, Apple Certified Refurbished products, include a one‑year warranty

Again, if time permits

Really & Genuinely interested in the outcomes

When two very esteemed colleagues weigh-in and they have 👍

I tend to take a back seat and follow their advise.

were you able to return it in person at the store you visited?

or did they tell you to ship it back to the refurbished store yourself?
