Warmer Weather or Software Glitch? R1S Efficiency Soars

Frunk Troubles: R1S Frunk Button Came Loose

On Tuesday, I went to open the frunk via the button in the bumper but instead the button popped out of whatever clip it's supposed to be held in. The rubber cover over the button is intact. Opened a service ticket just to find out the closest date available was late May. Yikes! It's not a critical issue of course as I can still use the key fob, phone or screen inside the truck to open it but I would love to have it fixed. I live a bit far from a service center and since I would rather not drive that far I opened a chat request to see if they could do a mobile service. No resolution yet on if they will go the mobile route but I found it funny that they requested a video of the issue, so i sent them a video of me filming the underside of the bumper looking at the rubber cover, pressing up and yep the frunk doesn't open, much good info to be gleamed from that. Service really is such an area that needs vastly more resources applied to it if they seem fully booked.

Recently, I’ve noticed my Rivian R1S is using energy much more efficiently since the weather warmed up in Vancouver. My driving habits, vehicle settings, and daily routes haven’t changed, yet for about a week, I’m seeing efficiency numbers in the low to mid 3s. My husband even mentioned seeing close to 4. Before this, over eight months of ownership, I never saw efficiency above 2.46. I drive in all-purpose mode, with standard suspension height and maximum regeneration.

Has anyone else experienced this? I haven’t calculated it manually yet, but it feels like the system’s calculations might have changed or there could be a glitch.
I’m curious if others have noticed similar improvements in their Rivian’s efficiency.

The sudden jump in numbers is surprising, especially since nothing about my driving or settings has changed. I’m wondering if warmer weather is making a difference or if there’s something else going on, like a software update affecting how efficiency is measured.

If you’ve seen this too, please share your thoughts. I’d love to know if this is a common experience or if I should dig deeper to check for a possible issue with my vehicle’s system.
