I really need help with my 2010 Yukon

These trucks run on a local area network (LAN) for comms between the modules, and as such it's vulnerable to interference due to bad shielding, weak terminal connections, etc. There are methods for troubleshooting the LAN comms, so that's where I'd start.

Diagnosing High-Speed LAN Concerns

Diagnostic tips may to help locate the source of a loss of communication with a high-speed LAN module.

We first got the truck in March, three days later truck would not start all lights on the dash showing up but no cranking check voltage had power, tried to use the key fob would only unlock doors no trunk would work no remote start, car had an accident from previous owner front end right side. First thing I replaced was battery ground with original replacement. Removing bumper realize that someone had crimped the secondary part of the ground on the sub frame one front end was fixed.
Didn’t solve the issue. Got a new ECM flash from flash masters did not fix the issue. Just recently replaced body control module also flash by the same company didn’t fix issue. Before I bought vehicle as well the car dealership admitted to me that they could not keep this thing going past a few days after paperwork was finalized, they’re are the ones that replace the battery and the alternator.

Based off of what you have said, pics supplied and that it was wrecked, I would start and concentrate on what @Geotrash has said. In the future, never be afraid of too much info supplied. The info about a wreck is likely the key here and we can also see the rust likely related to salt on roads where this rig lived before. Corrosion can be a PITA to these rigs.

As long as in chronological order and what was replaced or done and why it was done and test results and findings, never will you hear anyone here complain about info overload.

What is really bad is when the spelling leads to confusion and run on sentences where punctuation could clear those sentence meanings up. I have seen a 4 line paragraph here that was all one sentence and was very hard to decipher. Oh, by the way, old guys like me never like to be called DUDE!

Except, I think, @07Burb and @Tonyrodz, better known as "Triple T', for some reason. Weird that way. I think it has to do with where they live.

Sale it and drive to an area of the country where the vehicles aren't rusty (TX, etc) and buy another. Life is too short.

Lots of no rust rigs here in Oregon.

Bummer
If you saw the underside of mine you would cry. Almost zero rust.
