System Fault: Front Sensor Off, Service Suspension System Soon

[Taz10]

600 miles Gen2 R1S, 9 days of ownership, Ver 2024.27.30.

car showed offline, got in car and no response, moments later, 3 errors popped up, called service, did a system reboot, no change. Car drives in limp mode…every error on the dash appeared.

After service arranged for towing I left the car alone and walked away.

1 hour later, I see the app changed from offline to sleep mode. So I went back in the car and all errors gone, drove the car up the driveway no issues.

Will drive around the neighborhood for a day to see if it occurs again.

Welcome...sorry this is your first post. Rivian will get this fixed up for you. Seems like maybe a wiring harness issue. Please come back and let us know what they do to resolve it.

Something similar happened to me actually. My air suspension valve block got stuck, had the service suspension error and lost all my exterior sensors. The reason all your sensors went off as best it was explained to me is that all of them are on the same bus along with either something that actuates the suspension valves or related sensors. The architecture in gen 2 could be different but it sounds like the same sort of problem. The only difference here is I never had turtle mode.

In my case all of that is apparently all on there in series, so when one component on the bus enters a fail state it knocks the whole thing out. Originally I was able to clear the errors with a reset, but since the valve block was actually stuck and my air tank wasn't filling they came back once I had driven more than a minute or so and tripped everything out again.

I'd wager if it doesn't come back it was a sensor gremlin. If you want to test for this specific problem just see if you can raise/lower your drive height while parked. In my case all the sensors worked exactly until I touched anything to do with the suspension, after which they'd all error out.

In case you were wondering what a sensor gremlin looks like now you know.

Good recommendation- will test and report back

I get these kinds of 'errors' every once (1-2 months) in a while in my DM R1T.. in nearly all cases, the error goes away within about 30 seconds of movement. if it doesn't, a full reboot has cleared 100% of any remaining errors. I have about 13K on my truck now.

Tested in various modes including putting it on all terrain mode. So far the issue has not returned. Super odd

Yep. Sensor gremlins always after your loose electrons, especially if you park outside.

What you're probably dealing with is something on that one bus, and it's hard to say which one without the diagnostic data, randomly entered a fault state on wake. Since it's all in series it knocks out the whole bus. Then the computer sees that the whole thing is dark and throws up flags for every system on there, even if there's only one specific problem. I'm going to guess the hard reset doesn't kill power to it long enough for the problem component to lose all charge and actually reset, which is why the long sleep did the job.

If it happens again and you witness it though, push the hazard button and it'll record a diagnostic dump the service people can use.

it’s parked inside. Your hypothesis seems plausible. I do recall seeing in the app the car was showing “offline”. I didn’t think anything of it at the time. But when my wife got in to go, it threw all those errors. So far day 2 of use, issue has not returned.

To anyone else facing the issue, reboot may have helped but what really seems to be a fix is to drive the car a little with the errors, say 5 min, let all the sensors wake up and recalibrate. Turn it off, reboot the Rivian again and it should be back to normal.

Had these exact errors appear out of nowhere on my Gen2 this morning. Could still drive the car but stability control was stuck on medium, the car was stuck on 4wd (never seen that before on my dual standard), and adaptive lowering was disabled. I did a hard reset a couple of times spaced out over a couple of hours which didn’t clear the errors. Between that, I drove the car on an errand and that didn’t seem to do anything. Finally, after driving for about 45-55 miles on a road trip home, stopping to get some ice cream, and getting back in the car and turning on, all error icons were cleared and everything was functioning normally! So… software bug? Sensor bug?

One thing of note: I drove through a pretty violent rain storm last night for about 25 minutes. No flooding or anything but where it was hard to see out the windshield on the fastest wiper setting (which btw is not fast enough). So maybe a sensor got wet that shouldn’t have? This in itself would be a bit disconcerting so I guess I’ll ask the SC.

Lots of similarity, based on my experience it’s a sensor gremlin that clear after calibration. Doubt if the rain has anything to do with it, it’s massive truck with lots of ground clearance, sensors aren’t really bothered by rain… in my experience it’s just coincidence it rained.
One curious question, did you update to the 27.30… was it right before error

I am on that version but update a couple weeks before. Unfortunately, today the errors came back but this time accompanied by turtle mode (not able to drive more than 20mph) and some horrible braking performance. Had to pull to the side of the road. Luckily a hard reset fixed everything immediately. This is getting ridiculous though.
