That was my first thought, similar to when the sidewall gets a bubble. It looks to me like I hit a curb at 15 MPH.

With that many codes, I think I’d check for rodent damage right behind/below the battery box. As I recall, there is a fat sheath of wires that goes though the firewall into the junction boxes just below that battery box. Seems to be a hotspot for rodents. Rodents do seem to love these vehicles.

My LR4 made it back into town, I plop the battery on the counter after calling ahead yesterday with the OK to exchange it and they guy puts his device on it and says its OK, there is nothing wrong with it. After some convincing, he exchanged it for a new one under warranty and once I fired it up the check engine light never came on. The DIC is cleared of all lights now even after an 8 mile drive on a bumpy road as well as a couple miles the same road that it went bazerk on before.
This new battery from Oreillys is the same make/model and also made by Johnson Controls, but it was born just last month where as the last one I bought a few weeks ago in Arizona was born in March. Hopefully it doesn't break like the old one. I was tempted to buy a Land Rover brand battery, but they are supposedly made by Johnson Controls too so whatever the upo charge is, it may not be worth it unless Land Rover has specs that are over and above the off-the-shelf batteries.
I appreciate the help!

Costco is a good source too.

This. You need a gap tool, too many electronics in this car. It’s hard to point you in the right direction if you can’t give a proper description.
I can’t stress enough how important the gap tool is especially since you push your LR4 so much. trust me, it’s nice to have a clue of what’s going on with these rigs.
What I would do now is pull the battery and check for any evidence of water behind the battery, I believe the TCM and the ECM are located behind there on the firewall.
What you describe sounds like a water related issue but It also reminds me of the Panama special when Jeremy Clarksons shock absorber goes trough the body mounting of the 928 and pierces that wiring loom nearly killing the car. Check around and make sure nothing catastrophic like that occurred.
Also get an AGM battery like @ktm525 says

I ordered the gap tool last year. They took my money then canceled the order the next day and accused me of being a thief. F them.
