I did send the service advisor and manager a sharply worded email (though not disrespectful) regarding the lack of oversight when it was obvious there was a problem when the technician finished the recall services. To be fair, they didn't know the car wasn't starting but the message on the dash and the lack of any audio from the sound system would have been obvious. I still struggle with how they could have given the car back to me like that. I feel like this will fall on deaf ears though, I mean this experience is inline with the stories I've heard about taking the car to the dealership over the years.

As much as I'd like to, I can't keep the car on a battery tender, no outlets in the parking structure of my building.

Unfortunately, I'm not completely out of the woods yet. I only let the car idle for about 10 minutes after getting the fuse box sorted out and all was fine but when I took it out for a drive the following day, the CEL came on and I started getting all kinds of warnings about the EDC, DSC malfunction and a bunch of others and just as I got home, the wipers started. I orginally thought it was another battery issue but the battery is testing 13.4v.

When I scanned it, I had a ton of CAN bus communication errors with various modules so it seems I messed something up in the process, ugh!

A3AC - Message (distance travelled, 0x1A6) faulty, receiver KOMBI, transmitter DSC
A3AD - Message (engine data, 0x1D0) faulty, receiver KOMBI, transmitter DME-DDE
A3AE - Message (engine speed, 0x0AA) faulty, receiver KOMBI, transmitter DME-DDE
A3AF - Message (nominal road speed value, 0x200) faulty, receiver KOMBI, transmitter DME-DDE
A3B9 - Sporadic fault (failure, DSC message, 0x19E) No repair measures available, receiver KOMBI, transmitter DSC
A550 - Message (speed, 0x1A0) faulty, receiver KOMBI, transmitter DSC
CDA0 - Message error (terminal status, 0x130), DME receiver, CAS transmitter
CDA8 - Message (status, instrument cluster 0x1B4) faulty, receiver DME, transmitter KOMBI
D35A - No message (CAS 0x304), receiver DSC, transmitter CAS
D747 - EDC: PT-CAN communication fault
E594 - No message (steering angle), receiver FRM, transmitter SZL/LWS/DSC
E717 - Message fault (engine data, 0x1D0) IHKA receiver, DME-DDE transmitter
E71A - Message fault (torque 3, 0xAA), IHKA receiver, DME-DDE transmitter
E71C - Message fault (speed, 0x1A0), IHKA receiver, DSC transmitter

Any ideas??? The JBE was removed in the process of pulling the fusebox but was put back correctly, or so I thought.
Check the IBS (Intelligent Battery Sensor) blue connector plug is properly seated. Check the alternator output when the engine is running (it should be about 13.4 to 14V output and see the Intelligent Alternator Control manual attached). Then clear the codes, take the car for a longer drive e.g. 30 miles or more and see if the codes resurface. If they do, the list of codes smell like a bad ground, or possibly the battery cable recall splice still not thoroughly debugged yet. Be patient. A list of codes like that is typically caused by low voltage gremlins while driving. There is a way to monitor the voltage when driving via a hidden menu accessed through the BC column stalk. I don't recall how to access that hidden menu but YouTube will. Sorry you're having so much trouble. It's a long shot but the non OEM battery could also be contributing to the problem(s).

Edited: Added video and IBS/IGR Manual attachment.
