I have the OE blend. They always fill it during my monthly repair appointment at the service center. I read where one of the EV MFRs (maybe it was Tesla) warns against using the orange winter blend because it tends to streak over the cameras. Not sure if this is actually true..

R1S was sitting outside in cold weather like it always is. I cannot get the front or rear windshield washer nozzles to spray. It seems like they’re frozen and I also do not hear any motors running trying to spray. So maybe there is a sensor that shuts the pump off when it detects there is a...

I have never noticed this while charging the Rivian on long road trips. I only noticed this while charging the Tesla.

I’m referring specifically to preconditioning. I’m coming from Tesla, which do not use the battery for preconditioning the cabin if they’re plugged into the charger. I would prefer to minimize the use of the battery and limit charging cycles if it were possible.

This is interesting. I wanted to Defrost the snow from the G1 R1S windows, so ran the heat for 30 minutes. I noticed the SOC dropped from 70% to 68% during that time and it started recharging to get it back to the 70% I have set as the default. Wouldn’t this mean that the gen 1 R1S is using its...

it will do this, depending on specifically what has failed on the drive unit, I guess. The right rear drive unit failed on our Quad R1S in the middle of nowhere. It was the disconnect. Same symptoms others reported. Sounded like driving over rumble strips each time I would drive from being...

Our R1S has an efficiency of 1.6-1.8 mi/kWh in nice summer weather. This is with our roof boxes. In this cold 20F weather, the efficiency is 1.0. This is because I had the heat going for an hour total while the R1S is plugged to melt the ice and snow. This counts against the efficiency, I guess.

Here is an interesting update. I was out running errands for a couple of hours. When I got home I measure the brake rotor temperature with my IR temp gun. The brake rotors were around 20F, same as the outside air temperature. I was driving manually without Driver+.

i was hoping an R1S Quad would not need to use brakes for stability since it has 4 independent motors.

A soft reset mostly solved the problem with the Map. I still think the UI is too slow. I would be happy if Rivian fixes this.

I have the holiday update. Noticed since updating, the map is very slow, like actually unusable. Other UI element also have an unacceptable amount of delay. Reminds me of my old iPad Pro that’s getting slower and slower with each software update. I used to be able to pan and zoom fluidly to find...

I’m seeing a lot more brake pad wear / dust than with my Model Y. I wonder why? I’m supposedly mostly only using regen except when HOLD or in park. I have the regen assist off.

I’m the OP and I just received the strangest email from A2Z today. I already submitted the photo of my adapter and order information, so not sure what this is about. My name is not Yanet, so have no idea what that means. ?

Tesla Universal Charger. I had it in mind, then I watched State of Charge to see if Tom would give it a good rating, which he did. My rationale for getting the Tesla Universal was that the J1772 adapter cannot accidentally drop to the concrete and crack nor will it get lost. It’s either...

I know the AutoSocks work; they got me home in an ice storm last January in my Model Y. I had just a single pair and placed them on the rear wheels. This was an all-wheel drive MYLR. if I get these for the R1S Quad, could I get away with just a single pair and if so, would it be best to place...

thanks for all the replies. So, I just need to be a little more patient…

after sleeping on it and giving more thought, I’ve decided against using my $100,000 electrical outlet tester on that antiquated outlet installed who knows when. I doubt I can get answers to any of the questions / concerns you suggested below from the staff on site.

The place I’ll be working in 3 weeks has a 240V outlet that’s accessible to our R1S. I’d like to use the outlet for charging. The outlet has 10-50R / 50-AMP / 240V stamped on When I search on Amazon, I have no idea if the brands I’m reviewing are safe and reliable. Can anyone recommend an...

This is regarding the voluntary recall that A2Z is doing with their first gen NACS adapter. I placed my request with A2Z for a replacement adapter on December 10. Aside from the initial acknowledgement of my request, I have received no updates. It’s approaching a month now. Has anyone else...

I think the disconnects are the Achilles heel of the drive units on the Quad. At least with ours. One failed at 3K miles in the middle of Montana. Fortunately, the R1S was “smart” enough to force and lock itself into conserve mode, which allowed me to get it to civilization (Spokane). I don’t...
