AFAIK Tesla tries to produce as much as they can in-house. They are designing their own chips for their cars, for example.

- taneq 6y agoThat sure would make it easier if the regulation is written as "you must use the same supplier" and they can just say "yup, it me".
- MichaelZuo 6y agoPerhaps it is the biggest reason why they did that in the first place.
- numpad0 6y agoAnd that contributed to their stupid issues like skipping conformal coating and cars getting runaway power steering from it
- zaroth 6y agoCan you point to the recall from this? The recall I can find is to replace 3 bolts that can corrode due to salt which would cause loss of power steering. I’m not sure what runaway power steering is?
- numpad0 6y agoCrazy in a general context of cars but not sure they issued recalls? That seems normal wrt Teslas. IIRC the root cause was water intrusion into power steering ECU on MS P100D, could be rain or condensation.
- londons_explore 6y agoNot unique to them... An entirely reproducible power glitch in my early honda hybrid causes the power steering to steer at full power to the left... End result is the wheel spins with so much force it broke my thumbs... Lucky I was only doing 5mph at the time! It's 100% a design fault, and applies equally to any car of this model (I tested it on a friends, same result!). There are simple reproduction steps which can totally happen by accident, yet there has been no recall or service bulletin issued. I ended up pulling the power steering controller apart and adding my own safety circuit to the microcontroller output so my car is now the only car of this model which won't break your thumbs or steer you into a ditch!
- WalterBright 6y agoThe design fault is having a failure mode that leads to full power to the left, not the fact that there was a failure. I've noticed that automakers are about 60 years behind aircraft makers in design methodologies that prevent things like hardovers due to single component failures. I'm not exaggerating about the 60 years thing. I worked in Boeing engineering 40 years ago and the "no single component failure causing a crash" was the rule and literally the law. (A lesson Boeing had to relearn with the 737MAX MCAS system.) Nuclear reactors (Fukishima) and drilling rigs (Deepwater Horizon) are far behind, too.
- londons_explore 6y agoThis isn't even this level... There is a certain sequence of actions to make it do it... and it isn't hard to do by accident - it basically involves turning on every electrical thing (as you would do on a cold dark night), having a quite flat 12v battery (as would happen if you left the car unused for a few months), then turning the steering wheel while revving the engine (as happens while you're pulling out of a parking space). So park the car for a few months, then go to unpark it on a cold night... Not at all rare!
