Numerous Tesla owners have said they’ve been stuck inside their EVs after the cars suddenly lost power.

YouTuber Tom Exton claimed that his Tesla Model Y ordered him to pull over before it suddenly lost power and left him unable to exit.

Exton followed the instructions for the manual release to open the door, but he said this “somehow broke the driver’s window.”

    It’s no different than a steering wheel and brakes. It doesn’t matter if there’s some advanced electronics augmenting (or even controlling) those systems: there need to be a bomb-proof mechanical linkage as a backup.

      Tesla doesn’t use steer by wire, but some other car company do. It’s actually really nice for having a high steering ratio at low speeds and a low one at high speeds to be more precise.

      Plus breaks have been brake by wire for years now without mechanical connection.

        Brake by wire isn’t really very common afaik. Mercedes had EBC at some point but stopped using that system. It also had the downside that the SBC unit had to be replaced every so often to guarantee a working brake system.

          From the wiki:

          Ford, General Motors, and most other manufacturers use the same general design, with the exception of Honda, who designed a notably different design.

          Brake-by-wire is used in most common hybrid and electric vehicles produced since 1998 including all Toyota, Ford, and General Motors Electric and hybrid models.

          Seems pretty common to me.

            The three main types of brake-by-wire systems are: … electro-hydraulic brakes (EHB) which can be implemented alongside legacy hydraulic brakes and as of 2020 have found small-scale usage in the automotive industry; and electro-mechanical brakes (EMB) that use no hydraulic fluid, which as of 2020 have yet to be successfully introduced in production vehicles.

            The question now is what the other quote was talking about, seems a bit unclear to me. I omitted the electronic parking brake in the quote.

            EDIT: As of now I could find references to a total of 6 car models implementing brake-by-wire, two of which are already discontinued: Toyota Prius, Lexus RX 400h, Mercedes E and SL(both discontinued), Alfa Romeo Giulia and the Chevrolet C8 Corvette.

            Again, considering the current amount of models on the market, that’s far from common

              The Chevy Volt, for instance, has brake-by-wire, but I don’t think they advertise it as such. Most regenerative braking systems require brake by wire to function effectively, because you need to use the regen at higher speeds and physical brake at lower speeds, but only want the user to have one brake pedal.

        “Brake by wire” doesn’t mean there isn’t a mechanical linkage, just that the “primary” means of transmitting brake pressure is electrical.

        Between safety regulations, liability, the the potential for a PR disaster there isn’t a single road legal car for sale (yet) that doesn’t have a backup hydraulic or other mechanical system – the brakes must work if there’s a catastrophic electrical failure.
