Wiring problems of the 2018 Chevrolet Colorado

Brand new 2018 midnight edition chevy Colorado less than 24hrs on the engine and had less than 900 miles on it. Went to go to work one morning and it wouldn't do anything. No revere. No power steering. All lights and gauges were flickering and going crazy. Engine was chugging and making odd noises. It would not move from my garage/driveway. Had it towed it to nearest dealership. Over 2 weeks of diagnostics it's either a steering module or a wiring harness part. Dealership tells us its faulty wiring/steering module. It is an intermittent issue and it's hard to diagnose. I really feel that this could cause many safety issues since power steering was completely out and it wanted to shut off on us. This could have been bad if it happened while we were driving it to work. The dealership we purchased it from had done some electrical work but did not disclose what was done until it quit working and was brought to a different dealership. They brought it to our attention when it was towed in. The wiring that was done before purchase is what's causing all issues electronically. Truck is currently in the shop waiting for a part that is on backorder. Waiting for paperwork after repairs are completed. If they can be completed. They're still trying to fully understand the electrical issues since it is so random. It has been in their shop for over 2 weeks now. I just want someone to be aware of these issues incase it needs to be recalled. This could be a scary issue if it happens while driving.
