I do not have an answer, but I do have the same problem as you do. I have a 2001 L200, and from the moment you start the engine, every few seconds, the security light will flash and the temperature and gas gauge needles will act as if you turned off the car, and then pop back up where they should be. When the headlights are on, the dash lights will flash along with the security light and the gauges. The headlights and radio are not affected, though. In addition to that, the odometer has also stopped working. It has read the same milage since I noticed some time ago. I will let you know if I find out anything.

Check the daytime running lights module. This has failed with other manufactures resulting in lights that stay on, or are very dim while the vehicle is running.

running or parking lights, or plate light, but that is singular.

There are 3 different things that can cause the security lights to flash constantly on a 2002 Saturn Vue. These things are a bad passlock sensor in the ignition housing, a bad BCM, or a bad PCM.
