R1S Roll Back on Steep Hill at Red Light?!? Please help

[JCR]

Hmmmm... that's interesting. This is in regular drive mode with hold? Have you noticed if it would roll backwards on a hill or just forward, and did you notice that after an update or just all of a sudden??

Last time it happened was about three weeks ago. I haven’t noticed with the latest update. The few times that it happened was on regular drive mode. The few times that has happened it felt like the car was creeping forward. It wasn’t really a hill, more like a slight down hill slope. Hope this helps.

any 3rd party witnesses to the accident? without that or video from the Rivian or the other party's dash cam (no idea if they had one), there is no evidence that the vehicle rolled backwards and then it comes down to the testimony of the 2 drivers. Given that the vehicle is intentionally designed to hold its position when at a stop, there isn't the same opportunity for user error such as with someone driving an ICE with manual transmission, the other driver would have to prove that the vehicle actually malfunctioned.

have you attempted to reproduce the unexpected rolling by stopping on a hill? if you can't reproduce it seems rather unlikely there was a one time glitch that caused the vehicle to roll down a hill and cause an accident (note that JCR has a repeatable problem, albeit not 100% of the time).

This is definitely making me thing... sounds like it is possible. Starting to wonder if somehow it went into neutral but if that happened I would think the Rivian would roll pretty fast and cause serious damage. Well good luck with your issue... I'll look into getting the gear guard footage and hopefully it clears everything up!

At the time there were plenty of cars around but no one came forward. The issue is I just assumed the driver's claim was accurate so I didn't deny anything... insurance sided with them saying I admitted to it. But after really thinking about it I'm having doubts. Aside from one person on this thread, it doesn't sound plausible... unless there was a malfunction or somehow the R1S went into neutral. I'm just learning about Gear Guard, so I'm going to hopefully have an answer there. This happened a few weeks ago though, so hopefully the footage did not get deleted.

Exactly why CA has a handsfree law. You took your eyes off the road and stopped paying attention. Not the Rivian, it's the driver.

You're telling me you sit at a red light with hands at 10 and 2 and stare forward the entire time? You've never messed with the radio at a red light? Radio, phone, re-tying your shoes... all the same at the end of the day. Come on... be reasonable

You rolled backwards into a car at a stoplight, take responsibility, don't whataboutism me, I had nothing to do with it.

You need to see if you can reproduce the problem. If reproducible, the vehicle needs to be serviced. If not reproducible, the odds are low (but not impossible) that there was actually a rollback event as claimed by the other driver.

You could also reach out to Rivian and see if they have any telemetry from the incident. Doesn't sound like that evidence, if it exists, could work against you at this point.

I can't investigate, ask questions? What does that that have to do with not taking responsibility? By your logic if you're car rolled off your driveway that would be your fault for not standing there and babysitting it

I don't know if it's been replicated, that would be great to know. I appreciate the suggestion.

Another on ignore.

Fastest way to verify your fault / no fault will be with drive cam, and/or checking to see if you have ((H)) on the driver display which will indicate a Brake Hold failure.

Anything else at this stage is conjecture.

If the drive cam / gear guard shows you rolled backwards, you're guilty (regardless of truck tech fault). If it shows you were stationary and hit, then success - send to your insurance.

If ((H)) shows up then you're still technically at fault, but at least you know the truck's brake hold is borked and needs service.

That's exactly what I do. I'm operating a motor vehicle. That other shit can wait.

Yes, most people do not get distracted while stopped at a light. But, not everyone is so proper, perfecto, aka are humanos.

I would never admit to anything to anyone, unless I am 100% certain. Even then I limit what I say. And yes, I have fully admitted when I was at fault, even after “pleading the 5th”.

Like many have noted it is almost impossible for the R1 to roll back, unless you are in off road mode or deliberately shift into neutral.

Hopefully you have that gear guard video.

You didn’t roll backwards, OP.

The guy behind you is trying to take advantage of your situation. It’s more likely he took his foot off the brake and crept into you, or was on the gas holding the hill not paying attention.
