Nissan Maxima tail lights and turn signal lights stay on after engine off, causing battery drain on Nissan Maxima

Some Nissan Maxima owners report experiencing issues with their tail lights and turn signal lights remaining on after the engine is turned off, indicating potential electrical system problems. This situation may stem from a faulty switch, relay, or wiring short, which can lead to unnecessary battery drain and the risk of being stranded. Common causes identified include short electrical connections, a bad signal switch, a malfunctioning flasher relay, or faulty wiring and electrical connections. Additionally, if the tail lights stay illuminated despite using the on-off switch, it may suggest a fused switch or wiring fault keeping the circuit powered incorrectly. Owners are advised to conduct diagnostic steps, such as checking the hand-turn signal switch, to determine if the issue persists after turning off the signals. Prompt resolution of this issue is crucial to prevent battery drain and ensure the vehicle's electrical system operates correctly.
