Jeep Commander dash lights intermittently go off and on with check engine light flashing on Jeep Commander

Some Jeep Commander owners report experiencing intermittent issues with dash lights flickering and the check engine light flashing. These problems may be attributed to a faulty alternator, loose wiring connections, or a failing battery, which can all lead to the erratic behavior of the lights. Additionally, some owners have found that replacing the ignition switch has resolved similar flashing dash light issues. Problems within the electrical system, such as blown fuses or loose wires, may also contribute to this flickering. Furthermore, a bad connection between the ECU and the dash lights or issues with grounding, such as corrosion or faulty switches and relays, can exacerbate the situation. It is crucial for owners experiencing these symptoms to seek a professional diagnosis to accurately identify and resolve the underlying issues, thus preventing further complications within the vehicle's electrical system.
