Is it normal to roll back on hills?

    I'm just wondering if this is normal behavior or if I have "a problem"?

    If I stop on an incline and let up on the brake, the car will roll backwards like happens when you have a manual transmision.

    (I have creep mode off).

    Thanks

    That's absolutely normal. I use creep "on" and on enough incline, it will roll back a bit like on an automatic car.

    Hopefully TM will add a 'hill hold' feature one day. I would gratefully appreciate it.

    The new Standard

    I have a 2013 five-speed manual Jetta right now and it does not rollback on hills but automatically activates the brakes appropriately. It works quite well. If this basic sedan can have this feature I expect Tesla to have it as well. Or it's really just a coat hook trick.

    Thanks. Really wonder why, in a car with an automatic "transmission" (like with the MS), the hill-hold thing isn't just a given.

    Anyway, thanks for confirming this!

    Easiest way to combat this is to do the two foot trick. Use your left foot on the brake and right on the accelorator and depress them at the same time. Simply let off of the brake and the car will go without rolling back. The car will give a warning that you have both depressed at the same time but it's not damaging to the car.

    My automatic car rolls back too on steep enough inclines, so I'm not sure where this notion of "hill hold" comes from for automatic cars.

    If you turn on creep, the car will balance on modest inclines.

    But don't turn on creep.

    Terminology question:
    Why do you say the Model S has an automatic transmission? Or rather, what makes it not a standard transmission? Or better yet, do such terms even apply when there is 1 gear?

    That was my point in putting "transmission" in quotation marks, acknowledging that the term may not apply to this unique car.

    The Tesla Model S is a very intuitive car to drive if you are used to a manual transmission (rolling, deceleration without using brakes, etc). May seem odd to those who are used to only automatics. I can't see the the need for a hill holder on an automatic or the Tesla when we have a left foot to put on the brake. Maybe in a manual transmission with a clutch.

    Depends on which way you're facing. If you're pointing downhill and the car rolls backwards, I'd contact service right away. :tongue:

    Not to worry. I heard that only happens when the flux capacitor is inserted backwards. There was a TSB--NOT a recall--that changed the socket to make this impossible to do in the newer models.

    Hill Hold is useful in a manual transmission car because you don't have three feet (clutch, brake and gas), but with the Model S the number of pedals matches the number of feet, so all you have to do is hold the brake while you press the "gas".

    Yeah so the car can beep at you for holding two pedals. No thanks. Hill hold please. Most cars have it now, super easy fix.

    The Nissan LEAF has it. Mini Cooper I recently drove has it. Seems to be pretty common these days.

    I can see needing it if you only have one leg... :smile:

    If by odd you mean awesome, yes.

    If you want "faux hill hold", you can try Creep which gives you almost what you want some of the time.

    Disagree. It might prove to be, but we don't know that yet.
