More than 376,000 Tesla Model Y, Model 3s have faulty steering

It can be a serious problem without happening while the car is moving. If someone finds the steering unresponsive they won't be driving like they're used to when they try to get somewhere.
I'm picturing this being kinda like a rental car I had with start-stop engine.

At one point I stopped to make a turn (stopping with wheels forward, because you don't want them cranked into traffic in case you're rear-ended) then when there was a gap I went to cut across....but the engine start-stop apparently also cut power steering when it shut off for economy. I was briefly confused why the wheel wouldn't turn, then in the moment it took me to collect my bearings it had started the engine back up from start-stop. As the engine restarted, suddenly the steering became easy again and my "wrestle overpower it" made my hands slip when it turned with zero effort again, punching myself basically with all my strength as I slipped off the now-free-spinning wheel.

I've dealt with cars that had power steering failure, but when it changes seemingly at random is a much bigger issue while driving.

A modern car with a power steering failure is even harder to turn than a car designed without power steering (or for optional power steering) was. They used a bigger steering wheel and greater gear ratio when there wasn’t power steering.
Not to mention the weight of modern cars, especially BEVs.

A lack of power-assisted steering isn't the worst thing in the world—many readers will be old enough to remember when the feature was far from ubiquitous and parallel parking meant a bicep workout. But it's also not supposed to happen on such a safety-critical system.
Can confirm about the workout. Power steering of any kind was a luxury when I was learning to drive.

As for the "not supposed to happen on such a safety-critical system" part, so what?

It's not like the owner of the company isn't actively engaged in systematically dismantling all of the agencies that are in charge of enforcing action, and the ruler of the country isn't undermining the letter and rule of law with arbitrary insanity.

Our masters don't have any shits to give about the puling masses. They got in. They're not leaving without bloodshed. And in the meantime, any addressing of any issues that come up will be done only because the rulers of our country decide to do it when they're not busy creating them in the first place.

Electrical design issues in a Tesla power steering system don't make me feel better about the fully drive-by-wire system in the Cybertruck. I hope they put a bit more effort into testing that drive-by-wire system to root out long-tail flaws like these.
the habit of wheels (and whole suspension units) falling off with relatively minor curb hits - sharp edged cosmetic panels - lack of readily accessible manual door releases - and over rated tow hitches mounted to cast aluminum unibody rear sections

… worries me more

How has it causes 570 crashes while the car wasn't moving?
The article is clear that the problem won't start while the car is moving, but it will start after the car has come to a stop. So, the car comes to a stop, the power steering fails, then the next time the car is driven there is no power steering.

A fully drive-by-wire Tesla is actually safer. You can't hurt anyone if you can't even put the vehicle into motion.

How is it safer not to be able go steer at all rather than being able to steer with effort? Unless it fully disables motion that just seems like it’s worse because you could be, for example, in the middle of an intersection making a left turn and suddenly unable to get to a safe place.

That $400 million worth of Cybertrucks that Elon the Parasitic Illegal Alien from Africa can't sell to anyone but the Pentagon are going to go over really well under battle conditions after they add a few hundred pounds or more of "armor."
Try 8-10,000 lbs. That’s what a light armor personnel carrier would carry depending on construction.

The Cybertruck already weighs 7k.

It was supposed to be a joke about Tesla electricals being so shit that you can't even start a Cybertruck and get it onto a public road where you can hurt someone.

You can hurt someone if you can't stop the vehicle from being in motion, though. Assuming a full drive-by-wire system will not fail while in motion is incredibly short-sighted.

"Software recalls are only getting more common...As trends go, we don't like it." Sorry, OTA updates are far better than the experience with my old Volt for which it became harder to update. Even my dealer eventually did not have "a certified tech" to do the update. GM seemingly stopped updating the car as the Bluetooth standards changed.

Endemic to software development is the thought that MVP is license for poor quality rather than developing to core requirements. However, this is not just an automotive industry problem. I'm sure most cyber security professionals have experienced being told that security features are not included in the initial "viable product"

The trend we don't like is the fact that cars are being shipped with buggier and buggier software, requiring more frequent fixes. HTH.

Stop at red light, PS circuit board fries.

Light turns green, stomp accelerator while trying to turn.

I would take issue with this statement. I’ve driven cars without power steering, and I’ve had power steering fail suddenly on a GMC Safari minivan. The Safari was utterly unsteerable without power steering. Putting all my upper body strength into the wheel, it barely moved. Comparing vehicles designed for power steering with vehicles designed to be directly controllable seems like apples and oranges.

I'm trying to square the two assertions that the failure only happens when the car comes to a stop and the report of 570 crashes. Maybe both are true, but the number of reported crashes would indicate that this is quite a serious problem.
Try doing an unprotected left turn without being aware that the power steering just failed.

For those who do not understand driving without power steering, there's a simple way to get that experience.

Turn your car off on an incline (NOT an actual public roadway). In neutral, no emergency brake, slowly let your foot off the brake and try and turn.
... while keeping in mind that the brake is power-assisted too.

Don’t do this without turning the key or you will lock the steering wheel.

The range on those trashcans while under any real-world truck load is ~100 miles. Add heavy ballistic armor and it would be much less. They would need to fill the bed with a diesel generator and fuel tank to keep the batteries charged.

No. This scam of a contract is just to get rid of Cybertrucks that Elon cannot sell. They will be issued to motor polls on military installations to carry people and light tools. Something a Ford E150 would do better and cost taxpayers far less.

In my experience, trying to turn an unpowered power steering wheel is a fuck of a lot harder than turning a steering wheel that was designed to work without power assistance. I'm not sure why this is, but I assume pushing around a bunch of inert power steering stuff is making it harder. Also, those old manual steering wheels were definitely larger which gave you more leverage.
