2015 Chevrolet Tahoe engine problems

Tl* the contact owns a 2015 chevrolet tahoe. After the vehicle was started, an abnormal odor emitted from the vehicle. While driving, the contact noticed smoke under the hood of the vehicle and no warning lights were illuminated. It was discovered that there was shredded metal exposed and the air compressor was melted. The vehicle was not taken to be diagnosed or repaired. The manufacturer was notified of the failure. The failure mileage was 52,000.

4th and most dangerous of 4 incidents in 3 weeks of ownership of 2015 chevy tahoe lt. Without driver instruction or interference the 2015 tahoe shifted itself into 4wd despite dial on 2wd. Steering difficult, car jerked, engine revved differently and trouble in reverse. No warning signals on display and I didn't know what was happening. Drove .5 mi., pulled over restarted, and then "4 wheel drive, dismiss" on display over steering wheel (no seat vibration, flashing lights as with lane drifting).
