Default 2015 Battery Replacement

A buddy of mine replaced the battery in his 2015 last night and has a problem now.
He has no horn or lights and his key fabs don't work and the car won't start
Any help would be appreciated

Recheck all connections. One is probably not tightened down. Worst case blown main fuse.

Check the thin black wire is connected to the (-) post. It regulates voltage and is easy to break when replacing the battery.

That would be a good place to start.

I had this happen when I changed out my battery.

Usually you see a "low battery" message on the DIC if that wire connection is broken.

I doubt that would affect the functions noted by the OP, however.

More likely, as suggested above, one of the connections is not tightened up properly.

The contraption for the positive terminal sometimes seems like it is snug but still needs a few more turns with the socket wrench.

When mine was securely tightened, I noted my inside light came back on immediately with the open hatch. If the inside lights failed to come on while he was securing the battery, it suggests it wasn't adequately secured.

Thanks everyone for your input. Turns out he left the positive cable loose.
