Merged, now go to a shop that specializes in brakes and have the codes pulled.
When you say sensors replaced are you speaking of the hub assemblies at each corner?
it might just be the wires near the hubs, twisted and broken, that can happen running over a branch or replacing a strut!

Ok, all four hubs replaced, that points me to wiring harness problems, someone here a little while ago found their ABS sensor wire pinched no far up the wire from the connector near the hub!

If the ABS light is on you can get the codes read, then post the code NUMBERS.
Has the car been in any accidents?
Have the airbags ever deployed?
Has the car ever tipped more than 45 degrees?
Which light comes on when the stop and go is going on, ABS and/or TC?

How is the battery? If this car sits a lot, that might be the only issue.

ABS measures signals in a convoluted way, and if your voltage is low, it kind of loses it's mind.

Really top the battery up, reset these codes, and see if you still see anything. You can't let modern cars sit idle for months at a time without voltage problems.

I'm going to bite the bullet take it to the Chevy dealer in El Paso today

There is a control module. but is there more than one computer in the brake system. I guess I'm asking is ther a computer for the engine and a computer for the ABS system? Thanks
