Critical fault while driving on the highway

[COdogman]

Surprised you didnt get the voluntary replacement that Rivian seems to be doing.

Me too. I have an appt in July for my 22k service and asked for my 12v to get some extra attention.

While I do not have confirmation since RIVIAN says because of the loss of propulsion, they have to check every system and make sure they’re correct but at present they believe it’s a failure in the vehicle dynamics module.

So I went to pick up the car yesterday and they said they replaced the vehicle dynamics control module. Nothing else was wrong. They did not change the 12 V battery or anything and as I was driving away maybe within a mile I got another fault that says Service suspension soon. So I turned around and dropped it back off and they gave me a Rivian loaner.

Something similar happened to me, the supposedly fixed my Driver+ issue and soon as I hit the road, the same errors popped up again. I said screw it and went home.

Do they not road test repairs?

So I got the critical warning with a weird beeping sound tell me that my main battery is bad!!!(just happen on June 25 and the truck is in the shop since yesterday) The truck will not do anything else and about 10 minutes later it shut down completely dead! Thankfully it was again in my garage. The first time that this happen without the beeping noise it just when dead it was the 12v batteries which the replace about 3 months ago. Now it looks like it maybe the main battery??!?! Will see...

I agree with the others this sounds like a 12v failure. I just crossed 22k miles with my original and I am getting nervous about it failing too.

Find something to schedule service for! (half joking) but it worked for me. I had mine in on other items and they proactively replaced the 12V. 16k miles, 1 yr old and no issues were presenting. They added it to the ticket unprompted.

Me too. I have an appt in July for my 22k service and asked for my 12v to get some extra attention.

Nevermind.
Guess I should read the whole thread first.

My 2014 R1S with 8,000 miles had a similar incident. Going 73 mph on a 2-lane road in CA going to Mammoth for a ski trip, 55F with light traffic, midday. Both screens suddenly blacked out. Scary, like WTF… I was able to pull over and brake, no problem. Did a full reset, problem resolved, but the fear was there: when is it going to happen again under more intense nighttime conditions? Went back home 4 days later, no issues. The next morning, first mile at 20 mph, the front end started chattering and shaking, like the regen was cycling on and off HARD every second. The thing was not safe to drive
(The screens were fine.)

Rivian towed it to El Segundo even though Costa Mesa was closer.

They replaced the 12v battery. No problems since (3,000 miles added). Rivian couldn’t replicate either problem

My theory is that a weak 12v battery could affect your wipers and locks

Good luck! You’ll regain your confidence like I did!

So I got the bad news yesterday guys that my high Voltage (main battery) is bad and needs to be replace along with the heater. Apparently it was a short that happen that fry the heater and the main battery and I think the also fry the 12v batteries as well. So far Rivian said that will be replace and tested next week and then they will work on my squicky suspensions and the ACC cutting off on me and needed to do a hard reboot to fix. Do u guys think my truck is bad or a lemon? Anyone else has these issues or just me? does anyone else this happen to before?

Since the repair my RIVIAN has been working fine minus the radio that they’re supposed to get fixed next week. You may be better off posting a new thread since we’re audience limited here.

So they fix everything! However I had to take it back to them bc they scratch it and also to replace the cabin filter. Is in the shop for 2 weeks so far. They did gave me a loaner on both times.

To OP and anyone else who experienced similiar issue I hear you! I have followed this forum ever since I bought my 2022 R1T(VIN 10,3xx/8-2022 production date) at end of September 2022; but have never actively participated in responding on the forum.
My case “tops” yours and anyone else as follows: Mid September 2024, was my FIRST trip ever, for my truck to be driven outside of my local area(FIRST time more than 50 miles beyond my home) to attend Rivians only off-road class by 3rd party company at hollister hills SRVA.
I want to emphasize that My truck bought new sept 2022-sept 2024 has never been driven OUTSIDE of my urban town;paved roads,streets, highways ONLY until this off-road class after 2 years ownership.
Before class ended, our entire class of Rivians led by class instructors were taken out to do an easy trail run. I was the very last truck bringing up the rear.
About halfway in on trail, my truck SUDDENLY Died completely with NO Power, NO WARNING of any kind(instrument lights, messages)Both display screens complete black/blank!
The good thing was this was at a SVRA trail and at slow off-road speed and no other trucks following behind me!
I just sat there for about 5 min when power came back on with my display screens reading warning lights, icons and message that truck needs suspension services! My truck was stuck in off-road mode and I managed to turn back and return back to SVRA parking lot where there was cell reception ro make call to Rivian. After their instructions to do hard reset, truck operation returned to normal for me to return home. Rivian “could” only schedule earliest appointment months out to following year(Jan2025! if I recall correctly)
My main concern is realization that what if my truck died SUDDENLY without any WARNING along with COMPLETE power loss and no ability to even “limp” to safer spot, on a HIGHWAY, I am literally a SITTING DUCK and my life is at stake!
Thinking back I should have been upset enough to make Rivian make this a priority service appointment; especially now knowing Rivian keeps a computer log/record of every vehicle’s problems ONLY for several months!
My truck has been serviced but nothing wrong was ever discovered, with no log records and this has hung over my head from September 2024 to today!
So now I’m definitely NOT even using my truck as intended for off-road adventuring; freeway driving is limited and primarily use my truck locally on city streets in town! My daughter will not allow me to take my grandsons driving on freeways!
I feel I’m in limbo and want Rivian to resolve this but I don’t know how they can to be fair.
So I’m throwing out to the forum community, what should I do?
Despite all this, I still love my R1T enough to not want to get it off my hands!

Not sure what you want Rivian to do. Your truck doesn’t have any errors or issues now. If you have just lost confidence, you can do what a ton of others have done - sell the truck.
