When I lock the truck, I notice that the rear ambient light (behind the center console that shines on the lower plugs and rear seat heaters) stays on. I can't tell for how long it stays one, but when I come back after five minutes or so, it is still on. Does anyone know why it does this?

Retained power settings vary depending on vehicle, but a 20 minute timer is not unusual.

Yeah, I will test it (and report back) to see how long it stays on. I am curious as to why this is even a feature?

The "Retained power" feature has been around for a while. It keeps things like the lighter sockets and interior lights powered for a period of time after the vehicle is shut down, then kills all accessory power from a central relay.

A major reason that most, if not all OEMs went to this design is because it helped solve a growing parasitic draw issue many vehicles started having in the 80s & early 90s as tech in vehicles started to become more complex. Relying on each component to properly shut down turned out to be overly optimistic, and many vehicles of that vintage developed the dreaded drawdown problems that were costly and work-intensive to track down.

The new system assures that if there is a draw problem, there is one central relay to inspect or replace.

So, basically there is one main shutoff at 5-15 minutes that makes sure everything is off? That makes sense.

This just happened to me, too - only, the light that stayed on was the one over the driver side rear door. Seems a bit random!

I was supposed to get my lightning yesterday and a recall just got issued for my car. Door latch problem with the sensor so inside cabin light remains on can drain battery.

That is weird. I guess I should be happy it's only the rear light in the middle, so it looks like it does that on purpose?

bummer! Did they give you any estimate on when it'd be ready?

This week. I was omw to pick it up yesterday and the dealer told me about the recall. They ordered the latch sensor and said this week hopefully

I had this happen for the first time yesterday and then pushed the button in the interior turns on the bed light and it seem to turn everything off.

What button in the interior?
