Burning Rubber Smell After Driving or High Speed
A burning rubber smell after driving or at high speeds in a 2020 Chevrolet Silverado 1500 often indicates a slipping serpentine belt, a seized pulley, or a dragging brake component. This can lead to belt failure, overheating, or brake damage if not addressed promptly.
Diagnosis Details

Seized or failing pulley (e.g., idler, tensioner, or alternator) causing belt friction
Dragging brake caliper or stuck parking brake, especially after high-speed driving
