Similar post is buried in one of the numerous vampire drain threads but it was suggested that this may merit a fresh thread so here goes...
I, like many have experienced pretty nasty vampire drain on my truck since taking delivery at the end of November. Initially I didn't think much of it and was just thrilled to have such a great vehicle but the longer I had it, the longer it bugged me. So I started watching things like how often the truck was already awake when I would open the app (pretty much every time). How often it was on the network (almost all the time). What was it doing on the network (periodically sending data to AWS).
The truck was on the network quite often but wasn't really sending much data (20MB or so at a time) and just about the time I thought it was going to go to sleep, it would send another chunk of logs. So I started believing that something was keeping the truck awake and started to look for sources. The best known of these sources that is well documented is the now famous frunk latch error documented on Reddit. Because I didn't have any plans to drive the truck for a few days I decided to start some experimenting with the frunk area, particularly around the latch. First I tried adjusting the loop that is connected to the hood to see if that made any change. That actually seemed to make it somewhat worse but was pretty close to statistically insignificant.
Next I tried removing the trim from the front of the frunk. Pics below for clarification on which trim piece I'm referring to. Within hours it was clear that my truck was going to sleep more often and staying asleep for longer periods of time. Prior to removing the trim piece I was losing 4-7% per day and after removing the trim piece I was seeing 1-2% per day loss and even 12 hour periods where I would lose 0% and in one 12 hour period I gained a percentage point. After 4-5 days I stopped monitoring the drain closely and just left the piece off. After seeing these results, I also reached out to @shrink who was reporting similar loss to what I had seen. It appears at least initially to have made a difference for him as well.
Removing the trim piece is easy and doesn't appear to have any effect on drivability or functionality. Simply pull up gently on the 5 clips that hold the trim piece in and lift slowly from the middle. There are tabs on each side that slide under the adjacent trim pieces but it all comes out fairly easily. Pics below of the trim piece. The piece is sitting across my frunk upside down as though I had pulled it straight off and rotated 180 degrees.
Please keep in mind that I did not get approval from Rivian to do this and I take no responsibility for any issues that may come up related to this mod. I put my trim piece back in yesterday as I dropped off my truck at the SC for other issues this morning. My hope is that the upcoming firmware release and it's frunk fix address the issue and I don't have to think about this again. As always, YM/kwMV and happy drain hunting to all.
