2018 Chevrolet Silverado 1500 electrical system problems

Passenger front window auto up broke and almost completely severed a adult males ring fing tip. In a parking lot the window went up 'using auto up'. A friend was getting in the truck and had his finger unfortunately in the way the window did not stop after coming into contact with his finger and it was almost completely severed at the tip.

When the vehicle was started, a loud squealing sound was heard coming from the vicinity of the front of the engine. While under the oem bumper to bumper warranted period, chevrolet dealer number one was not able to determine the problem or repair it. Furthermore, the problem was not reported in the vehicle history as reported. A short period later, chevrolet dealer number two was able to locate the problem and repair it at my personal expense as the warranted expired on time as opposed to mileage.
