Cv shafts keep popping out

[Offgrid]

500 miles in the rear cv shaft popped out on the driver side and stripped the splines on the disconnect. SC replaced the cv shaft, disconnect and the wheel hub.

1 week later (today), the exact thing happened again..

the symptom is rhythmic clucking followed by pop and spline grinding noise and the turtle mode with awd unavailable message.

Oh no! Sorry to hear this, following!!!

Wow, what a bummer. What are you driving patterns like? Do you often change the ride height? Use conserve mode? Tow heavy loads?

Off-road daily. 3 miles each way of dirt to get to my house.
suspension cycles from low to high daily. yesterday I cycled to highest in offroad mode and then this. I’m wondering if the axels just aren’t extending enough and pulling themselves out of the disconnect at the highest setting. Even so there should be a c-clip or roll pin retainer to hold the shaft in at both ends.

As I have mentioned ad nauseam at this point... Rivian has a serious problem with their half-shafts and CV Joints. Simply replacing blown parts with the same spec/soon to be blown parts is not "fixing" the situation as the OP has just proved.
Just like the broken tonneau system... Rivian needs to take a serious look at their CV Joint/half-shaft failures and actually address the issue in a meaningful way or they are in for a steady diet of failed/expensive repairs and a lot of really pissed off owners.

Yeah it seems like this tech is reaching too far for where the CV joints are at. For me personally this isn’t a huge issue as I’m not an off road guy, my truck lives in sport mode. It is good to know though that if I am going off road to keep it to high max and take it easy.

Beyond upset owners once this gets in the media that the suspension issues are frequent without real solutions you’d think that would turn off interested buyers. I told myself I’d never buy an Audi cause of all the transmission issues that were reported on their earlier vehicles (I’m sure it’s better now). Hopefully they fix this and it doesn’t turn into a bad rep that sticks.

My truck is in Brooklyn right now for what looks to be a blown front motor @‘sub 800 miles which was preceded by CV joint noise, But only on the morning of failure.

The loaner they gave me (which I’m very appreciative of , don’t get me wrong) also has CV noise and went into turtle mode this morning. The other loaner I had when my truck was in for a bad TCM module at 300 miles also had CV joint noise. So the three Rivians that I’ve driven all have axel \ cv noise, not to mention the suspension

I too use the available drive modes and suspect they don’t like changing height.

Would it matter whether the ride height change happened in park vs on the move?

"Within Spec..."

I wondered that too. It’s possible.

Hahaha. Just like the passenger side lean

Well, not as serious as blown driveshafts... "the lean" is another issue they are choosing to ignore at customers expense. I would be relentless if my $80K vehicle had a ridiculous lean condition and I got treated with the "sorry, there's nothing we can do.. thanks for coming in" attitude.

"There's nothing we can do" or "that's normal" are the kinds of responses you get from Service when a solution hasn't been provided to them yet. I fully expect Rivian's engineers are well aware of all of these issues and are working with their suppliers on a solution. But, it takes considerable time to diagnose a problem, engineer a solution, and then start production of the revised parts.
