Question electrical problems

Greetings and thank you for taking time to read this; hopefully I can get some answers before I decide my next move.

We bought our 2011 about 2.5 years ago with about 70,000 miles on it from a GM dealer. Since then, we have had to replace the engine, was told we needed a new transmission, had front end work done, rear brake work, and now we are having electrical problems. Every once and awhile, the tire light comes on and indicates a low front right tire (not the case), the air bar light comes on and the dash reads "service air bags," no problems there, and again, sometimes the dash board shuts off briefly (less than a second or two) then comes back on. Last issue: the turn indicators will sometimes stop working and then come back on.
I would take it to the dealer, but after the transmission episode, I will not go back there. Their advice cost me $500.

the low tire--- the PSI may be just on the border of being low....
once you drive -it heats up enough to be OK- and turn off the light.

If this occurs 1st thing in the morning- when all is cold- I would add just enough air- to bring it up to 35 PSI- cold.
Use a quality gauge.

On my 2008 there was a recall to re-work the Air Bag connectors under the front seats due to possible bad connections. Then several months later there was another recall to eliminate the air bag connectors under the front seats because the rework didn't eliminate the problems altogether. The first one was performed by a Chevy dealer. The second one was not done because I don't remember if I got a notice on that one or not.
Fast forward to 2018, My truck displayed the Service Air Bag light, then the dash lights went out then back on again and brighter than ever, Traction Control Light, TPS Light. No Gauges, No Radio no odometer.
I drove 120 miles and it didn't register. I got home and got into the driveway, stopped it and tried to start, it ran for about 10 seconds and stopped. I let it sit overnight, tried it the next day and it was fine. I had a friend with a Snap-On diagnostic too check it out and the problem was traced to the Air Bag Connectors under the seats.
I performed the Recall procedure myself by soldering the wires directly, the procedure and kit is here. https://www.lawsonproducts.com/image...SB14030_AD.pdf
You should check for any recalls on the 2011. Wait, I just did, and there is one.

Check to see if the recall is still open on your truck.
The truck was problem free after I eliminated the connector.

All of the problems point to BCM (Body Control Module).

That's what I was told also so I purchased one and the friend with the Snap-on diagnostic tool was going to program it with me that's when we discovered the air bag relation to my problems.
So now I have a spare BCM, I wonder if it would work in my 2015.

You know, Car for me is something more than just a car. I bought my enclave about 10 years ago and I spend so much time with it. If you have something to repair. Just sit, take a little relax, anybody could try here the CBD oil to keep calm. You don`t need to make something in the stressfull situation, cause the result may be very bad. The car is like a child and you don`t need to be fast. So hope my advice will be helpful.
