NHTSA Complaint #11618794 — 2022 RAM 1500

This report pertains to the lighting system of the vehicle, specifically the parking light mode of the lighting system. When stopped at a dark, unlight turn out, with the engine turned off, I turned the head light control switch from "automatic" to the parking light position to ensure visibility of the vehicle to other drivers approaching/entering the turn out. I confirmed via reflection that the lights had turned on. Later, when I exited the vehicle to retrieve belongings from the back, I noticed that the lights were no longer on. I switched the light control to the off position, and back to the parking light mode, which activated the lights. I noticed an indicator on the dash. However within a few minutes, the lights were again switched off by the vehicle, the only notification being the absence of an indicator light on that dash. This unexpected, automated behavior put myself and others at risk, by reducing the visibility of my vehicle to other drivers near (but not on) a dark highway. This specific issue has not been brought to the attention to service personnel, as it appears consistent with other non safety critical lighting behavior which has been reviewed and deemed functioning as designed. There are no error codes or other diagnostic indicators present related to this issue.
