Problem overview

Some Chevrolet Impala owners report experiencing ignition switch problems that can lead to ignition failures and challenges with starting the vehicle. These issues often manifest as difficulties with the electrical systems, affecting components like the radio, headlights, and windshield wipers, which can negatively impact overall vehicle performance. Additionally, some owners have reported overheating and coolant boiling, indicative of potential malfunctions in the cooling system, faulty thermostats, or leaks that require prompt attention to prevent engine damage.
