Steering Tie Rod Assembly problems of the 2014 GMC Sierra 1500

On making a turn at low speed, my engine has cut out completely. I had full loss of acceleration, power steering ,ac, radio. I put the truck in neutral and restart the engine to get to safety. This has occurred 3 times in the last 20 days. Twice in city traffic, once on the highway, turning off for gas. The "service steering assist" light appeared. I took the truck for a full diagnostic at a local electric repair shop, for $170. 00. The tech found nothing after hooking my truck to his computer. The day I retrieved my truck from the electrical shop, I stopped in walmart for groceries. My key fob would not lock or unlock my doors. I manually unlocked the truck to determine that the truck would not start at all. No panel/ interior lights, no response in ignition,no automatic unlocking, the truck was completely dead. Roadside service came to tow it, and the truck was jumpstarted from his battery pack. The key fob began to work, unlocking,etc. I towed the truck home. I have VIN checked my truck and there are none but I believe my vehicular failure refers to gm part 573 safety recall 17v-414 regarding the loss of eps. A secondary recall which may apply is gm# 14v26000 re steering linkages, tie rod assembly. As the "steer assist' alert was what I saw. I have the work invoice from the electrical shop, if needed.

I was leaving a store parking lot and began a left turn when the steering wheel was wrenched out of my hands as it spun around causing my truck to veer sharply to the left and to hit another stationary vehicle. GMC service department said the steering was broken and proceeded to replace the steering module. I retained the old module as evidence the tie rod became disconnected causing the accident. No one was seriously injured although I has the skin on my hand and forearm rubbed off by the steering wheel.
