What owners report
While driving the factory floor mat can slide under the rear of the brake pedal while it is being applied. Once pedal is released it will still hold brake pressure causing brakes to remain engaged while still allowing vehicle to move down the road in turn causing brakes to heat up and either lockup/ catch fire or once cooled become inoperable. We have heat marks on exterior of front drums and pads were glazed over.
