Starter problems of the 2017 Chevrolet Silverado 1500

The codes should not allow you to use the starter and it dose will be goiing down the road and loses power. Went through 5 wire harrnesses with in the 5 months.

Vehicle was parked in a shopping center parking lot after being driven for approximately 15 minutes. When returning to the vehicle 10 minutes after parking it, the vehicle starter was attempting to start the vehicle despite no remote start or onstar app being activated to start the vehicle. The vehicle continued to attempt to crank and start, even after I unlocked the vehicle with my key fob, inserted the key into the ignition, and attempting to start the vehicle and turn off the key. The vehicle continued to attempt to crank and start and I smelled a strong electrical burning smell. I then saw blue/greyish smoke coming from the passenger side where the hood meets the windshield. I then gathered my belongings from the truck and watched from a safe distance. After the smoke, the truck no longer attempted to crank or start itself and the smoke was gone within 5 minutes, although there were small instances of smoke over the next 15 minutes. The truck was put on a flatbed tow truck for further diagnosis at the local Chevrolet dealership. Initial diagnosis indicated that the "starter had consumed itself" and was the cause of the smoke I saw, but no further information was available. It was quite scary to have a truck attempt to start itself with a small electrical short/fire as a result without a key being needed.
