It's a little overkill to characterize this as "faulty" steering. Given that it's a durability issue. And in any case, they're being proactive. Not dragging their feet as manufacturers did over corroding Takata airbag units.
The important difference is that those cars were designed for you to steer and brake it without assistance. Different gear ratios and such.
I had to drive a modern car home once with the power brakes malfunctioning and I couldn't exert enough force (grabbing the steering wheel to give me leverage) to have safe braking power. I ended up going very slow in the emergency lane of the highway in second speed so that motor braking could help me stop. It was not fun.
No, this was a modern car, with power assisted steering and brakes. Steering required more force, but wasn't that hard. Braking was iffy, I admit, so I also used engine braking and the hand brake.
And yes, standard transmission. I was coasting downhill in neutral, with the engine etc off. Testing the running start protocol, for dealing with battery failure.
i've driven an old car which had power assisted steering that would occasionally fail while the car was being driven. you could still turn the wheel, it just suddenly required a lot more effort.
i suggest this thing is mainly going to be a problem where the power-assist fails during a trip at some unpredictable and unfortunate moment. driving where you know you won't have power-assist for the entire trip would be far safer.
Bay Area people are known to spend a lot of time in Tahoe when it's cold. So this is more, "Let's repeat that untrue joke about people in the Bay Area knowing nothing about winter."
Regardless of whether Tahoe winters are “real winter” or not, I don’t think they use salt in CA because of the environmental effects downstream - I believe they use sand instead.
California has a variety of climate areas, and a little googling tells me that they use various kinds of salt in the high Sierras, including the Tahoe area. Also, half of Tahoe is in Nevada, which uses salt.
Sand only works when it's barely freezing. Which can be true at low elevations, but not at 10,000'.
Normally I'd be the first to beat up on Tesla for not actually knowing how to really design or build a car (they don't) - but in this case, its not as if they're the first auto manufacturer with a similar problem.
(To be clear, my issues with Tesla is that they do not have the internal manufacturing expertise - or the design expertise for automobiles, and this shows thru parts availability, several recalls, and their slow pace of production - you can't design components with the same tolerances you'd build a MacBook Pro with, and use them on a car, and expect it to work well for manufacturing at scale)
Ah, the usual "designed in the Bay Area" issue...
