Rivian Ownership Experience Thread
12v warning or not I drove the R1S into the office today. I have an appointment for next Wed via mobile which means i have to reschedule a blood donation, but it's better than the August date they were trying to give me before. The good news is that even if I had to go to service center, the one in Blauvelt NY is open and despite being 90 minutes away, its much better than driving to the horrible location in Brooklyn 
it said to expect lower efficiency but I was getting the same as usual on the way in. I'm going to avoid checking the app until I need to go to the car to avoid unnecessary waking.

Tesla has switched some (all?) to Li 12v batteries. Hopefully that will help it be more reliable. The most frustrating part is I would have changed it earlier except I had the false sense of security from knowing it would warn me

When our Model 3 12v died with no warning it was horrible. Got stranded at work and had to Uber home after duct taping the window that was stuck cracked open since rain was coming. Mobile service came a couple days later and went through their procedure to replace it and got stuck when the car inexplicably refused to accept unlock commands. Had to get towed to a service center.

. My wife's 2020 Ioniq's 12v decided to die early, left her stranded at work. Hyundai sent a tow truck, but we couldn't get it on the bed because wheels were locked, and no power to get into the screen to put it in "tow mode". Luckily the tow truck drivers quick thinking when he saw the 12v battery and pulled out a portable jumper...that did the trick and we got it on the truck bed and it was dropped off at the Hyundai dealership (Friday night). This was during COVID, so I had to make a bunch of calls to the dealership, but got the battery changed the next day.Tesla has gone to a 14v Li ion which is much smaller, lighter and less prone to failure
I appreciate the early warning from Rivian, but more detail would've been welcome. If it's dying, how much life do I have in it? When I asked if I could drive it, the response was a vague non answer. I figure, if it dies, I get a free tow and get the car fixed sooner

At least you got a warning. The only warning we got from the Ioniq was a few days before the car was acting funny, doors wouldn't unlock right away, start button wouldn't respond etc. Then the day the LV batter died my wife got stuck, the interior lights were acting funny and the car just died

12v issues are pervasive, far too commonplace for one of the lowest tech components in an EV. 12v batteries have been a problem with F150 Lightnings too, but the main issue has been the battery monitoring system rather than the battery itself. The BMS was failing in two ways, under-reporting the 12v SoC causing software updates to refuse to install and then over-reporting the SoC at other times causing the charging system to think there was no need to top it up. The fix was a BMS sensor replacement and there was a customer satisfaction program that took care of it.
Before watching this video - well how hard could it be to change the 12v?
After watching the video - now I understand why they said the Gen 1 R1 lines are over-engineered / over complicated

That's why we haven't done many long trips in the Rivian. EA reliability in the NE is weak at best and even Tesla SCs tend to be V2.
Side note: I saw 4 other Rivians driving into the office today. My portfolio is happy to see more popping up

Ain't that the truth. Small amount of chargers per location, chargers always down or slow, etc.

$200 for an adapter and you're good to go with Tesla SCs. You'll have to consider parking arrangements if you get into a busy SC, but you guys have plenty of V3 and V4 superchargers over there.
We're doing a longer stretch from NJ to Boston over Thanksgiving and if it wasn't for the adapter and SC access, we would've taken the Ody. It's only a 1 stop trip and there are some non-Tesla chargers along the way but it's nice to have one that I can trust to work.
