The vehicle has been great. It feels like when I got my first Model S 9+ years ago....some odd software things, growing pains at the service centers, but tons of frequent software updates that make big changes similar to Tesla early on.
As an example, when I first got my R1S, the harsh suspension (no matter the setting) would have been my biggest let down. I did get the all terrain tires, so I was not expecting a ride on butter to begin with, but then the most recent software update made the air suspension "more comfortable". I thought I would not really notice a difference, but it is amazing. Speed bumps and driving on uneven concrete panel roads (Seattle) went from pretty jarring to extremely smooth and leap frogged how I would describe the air suspensions on my MS's and MX. How that can be done with a software update is amazing.
Another note, I love having Tidal as one of the streaming options in my Rivian. The bitrate/quality is so much higher than Spotify or LiveOne (if you pay for one of the higher quality options). Also, there is a built in hot spot. I thought that would be useless, but on our first road trip, there were times the car had service when our phones did not, so that kept us connected the whole time...for free.
I also had a small battery backup for my house that would keep the fridges and internet and some lights on during an outage. No need for that anymore since I can get 2000w from the outlet in my R1S and plug it right into my power inlet which will keep the house going for a week with everything we need. We also used the power outlet to run a two burner induction stove and fridge cooler while camping. No need for gas to cook or ice for the cooler!
Service with Rivian has been difficult to get quick appointments for because they are inundated (similar to my experiences with Tesla from 2014 to at least 2019), but Rivian has been so much easier to work with compared to Tesla in the past year. Just the fact that Rivian calls when service is done (or when there is any sort of update) with the vehicle makes the customer service experience so much better than the glitchy Tesla app that might or might not deliver the service messages. The number of times the Tesla app notified me of a new message from service only to show no new messages over the past two years is in the dozens. It was incredibly frustrating. And then if you try to call the service center, the system yells at you "You MUST use the app for all service requests", but the app does not work and nobody at the service center answers the d*mn phone. At least Rivian has answered 100% of the time within a few minutes so far.
That cover it?
