How to repair an intermittent BCM/electrical problem with Chevy Cruze 2015?

What is your question?

I have a 2015 Chevy Cruze,have owned this car for the last 8 months. For the last 2 months, I have experienced random radio blackouts (disconnecting/lost of power), stability traction &brake lights randomly comes on, and most importantly the lost of power steering. It has been to 2 different local Chevy dealerships, and a local auto repair shop. The car has sat with the repair shops for several days at a time, and all have not been able to diagnose or fix this problem. The first Chevy service center applied dielectric grease on the connectors of the BCM, a week I was experiencing the same problem. All 3 repair shops stated the problem is intermittent, and they see some BCM codes but can't fix it because the problem is intermittent. Each of repair shops told me they can't properly diagnose this problem until it is permanent . I drive everyday in fear, tightly gripping the steering wheel due ue to the constant loss of power steering. Please help
