I don't think that's true. I owned my Rivian at that time. There was a recall but I never received any instructions similar to that. They had everyone drive to the nearest service center to have the bolt torque checked, or you could book a mobile service appointment. You can see the Oct 6 2022 recall information here, including what they instructed people to do: https://rivian.com/support/article/recall-information

I think you are giving them too generous of a reading. The notice was that a subset of vehicles had loose bolts in the front end. They did not know how many, and there was no way to identify the subset. If you could be in this subset, stop driving the vehicle. This applies to everyone, on a rational reading. It was weeks before the guy drove out and checked mine.

Where did they say "stop driving the vehicle"? I don't think that happened. The instructions were to drive the vehicle to a service center for a drop-in check (or wait for mobile service) which obviously wouldn't be possible if you couldn't drive it.

It's worth noting that crack formation is affected by more than just the design - variation in material and manufacturing steps could also contribute. A more robust design can potentially compensate for material or process variability, but those variables were likely not known nor knowable during the design stage. We should not boo companies for acknowledging and correcting issues which may not have been reasonably f…

I would have thought that material and process variability would be one of the primary design constraints in physical engineering?

And if engineers were all knowing that is how it would work. Unfortunately the real world is complex and there are limits to how variability can be constrained.

> those variables were likely not known nor knowable during the design stage. But they could have included an error factor in the designing process. I thought this was standard for manufacturing. And they could have done more robust testing which, again, I thought was pretty standard for manufacturing.

They almost certainly did. But that error factor is a guess based on limited testing. You never know your true variability until you're building at scale. Waterfall development doesn't work in the real world any better than it does in software.

Yes, absolutely. The Cybertruck was indeed the first of its kind to have 4 wheels attached to its structure. No car company before Tesla had ever done this before and as such, it was impossible to gauge what kind of material was best suited to handle stress over long period of time. It's just ridiculous.

Tell me you're not an engineer without saying you're not an engineer.

The majority in that statistic are selectable 4WD, which isn't the same as AWD. Pushing the two groups together skews the numbers a bit. Most trucks since the 1970s have been 4WD, ever since companies like Muncie and Borg-Warner started selling axles to Ford and their cohorts. AWD trucks are a relatively new phenomenon, with the first one I can think of being the limited production GMC Syclone in 1989, and it being a…

Push the goal posts of you want. OP specifically said rear wheel drive. There’s a whole community that doesn’t consider anything without front and rear lockers, dana 44 axels, frame on body, and 37s with bead lock a real off road rig.

There is a difference between AWD and 4WD, because 4WD trucks are RWD until you manually change the mode. AWD is all on all the time and is FWD biased, usually something like 70:30 F:R. For most of their lives, even when towing, 4WD trucks are used as RWD only. As for specialized off-road vehicles that wasn't what we were talking about, but yes those people split hairs down to the micron for what constitutes what.

What sort of engineering standards are these Cybertrucks built to? Oh, very rigorous engineering standards. The wheels aren't supposed to fall off for a start.

Blame it on a loose nut behind the steering wheel.

Indeed. The insane part is not that Tesla built an absolute dumpster fire of a vehicle, that was something that should have been obvious at every point.

The insane part is the number of people who were somehow able to put up $120k for one, and proudly boast how awesome their new car was even though it spent most of its time in the repair shop or breaking doing very basic things, and failing to do "Truck" things that even my hatchback can manage.

Presumably it's not a coincidence that so many of them were bought by brand new weed shop owners.

Or, better yet, a minivan. People think they want a pickup truck, or an SUV, or a Cybertruck, but what they really want is a hybrid Toyota Sienna.

can't fit 4 bikes in a minivan . on my previous SUV I had a rear rack and its such a PITA

You cannot be serious.

It was trivial to do this back before foldable seats were standard.

You can fit at least two bikes in just the shitty "trunk" space of your average minivan.

Every van ever made has more cargo space than the Cybertruck.

Same standards as e.g. 2026 Audi Q8 e-tron: "Popular electric car recalled due to brake pedal problem" [1] A problem with a "screw connection" (unclear whether this is a mounting screw or it serves some other purpose) can cause the brake pedal to malfunction. or, in 2024 Audi Q4 e-tron, Volkswagen ID.3, ID.4, ID.5 and ID.7: "Dangerous error in popular electric cars: brakes can cease functioning" [2] It says that the…

Dang you nailed my profile perfect. I bought one and its the best car I've ever had. Event though I was never a "truck" buyer it checked off all my needs: - space for wife, car seats + another adult when needed - haul around my kids, 4 bikes, skis, camping gear, etc. - drives itself - we do a ton of road trips - luxury - electric, tired of going to gas stations Wasn't another car on the market that checked those boxe…

A Cybertruck cannot physically fit 4 bikes, and the truck bed is not long enough to fit skis or snowboards.

When I go biking and snowboarding with my idiot friend that owns a Cybertruck, we have to use my Outback to haul the gear because it won't fit in his lemon.
