A squirrel entered my ID.4 through the right wheel well while I was at work and it began to make a nest in the front of my engine compartment. I was alerted to the problem by all of the dashboard warning lights flashing the ACC and related front safety systems. The squirrel had chewed through the harness wires down to the connectors on the 8 and 9 connectors and the 6 pin connector. I know it was a squirrel because I saw it in the engine compartment when I opened the hood and other coworkers had nests in their hood areas. No damage to thier vehicle because the critical wires were not so carelessly exposed.
