2024 Rivian R1S Dual-Motor — anyone else: Apartment charging without a dedicated garage outlet

ColdStartGal16Community StarterApr 14, 20262024 Rivian R1S Dual-MotorSeattle
I can charge at work sometimes but not at home. For people living in apartments, what combination of public charging, workplace charging and occasional fast charging has actually been practical? Any data points from owners would help.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2024 Rivian R1S so service can see what you saw. Then you'll know the next fork. Was this after sitting overnight? I refuse to clear codes until someone else sees them.

I'd treat 12V warnings as a no-ignore. On the 2024 Rivian R1S, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. That's where I'd start. On “motor — anyone else: apartment charging without,” that was the fork that mattered for me. That's the whole play. Checking again after work.

OP update: scanned the 2024 Rivian R1S again and still only have the one pending code, no new lights. I'm keeping receipts and dates in one folder.

I'd push back a little: Try a second charger before blaming the 2024 Rivian R1S — site sharing and pack temp change the curve a lot. Then you'll know the next fork. Did the worksheet show tax yet? Wrote this up on my lunch break.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2024 Rivian R1S charge sessions. I'd do that before spending real money. This is from a 2024 Rivian R1S in Seattle. Write the result down so the next test isn't a repeat of the last one. Make the next action something you can finish this week. Not interested in a five-hour wait for a shrug.

Climate here is different, so treat that as a local data point. Cold start is when I can actually reproduce it.

Fair point. Counterpoint: Try a second charger before blaming the 2024 Rivian R1S — site sharing and pack temp change the curve a lot. I'd do that before spending real money. Parts cannon is a personality type I try to avoid. I'll update if anything new shows up.

I hear you, though I'd still want a second check. Leave the alerts on the 2024 Rivian R1S so service can see what you saw. Then you'll know the next fork. Monthly payment math is how wallets disappear. Checking again after work.

That's a good start, but I wouldn't stop there. Match starting SOC and battery temp if you're comparing 2024 Rivian R1S charge sessions. I'd do that before spending real money. If you share a photo of the worksheet, easier to sanity-check. Not driving it hard until I know more.

This is from a 2024 Rivian R1S in Seattle. Monthly payment math is how wallets disappear. That's coming from doing this as an owner, not a shop. I keep a notes app thread for this now.

Checked the easy stuff on the 2024 Rivian R1S and found one clue worth chasing before I book a shop. Happens in gear, not in park, for what that's worth.
