Why didn't the Model S cross the stream?

Would you cross this creek in a Model S?

  1. Yes, depending on water level.

    Because I'm too chicken to risk it. And I only have a coil suspension.

    But I'm wondering when our 100D arrives with SAS, will it be safe to take it across at the high setting?

    The stream is usually only 6" deep, with spots going to 12" though. I can move some rocks around to make it safer and more level, but I've gone across in a 944S2 and a Mercedes CLK 500 with conditions close to how it is now.

    I managed to get power across the walking bridge, 250 feet of heavy duty extension cords from my neighbor's hunting cabin is getting 9 amps to the car, giving me plenty for the return trip with a stop at the Glen Allen supercharger near Richmond VA so long as I don't drive much during a typical 2 day stay.

    I'm just curious if other owners would take the risk and cross, or should I plan on just carrying my luggage across the walking bridge and the last couple hundred yards to our house from now on? AP makes the 300 mile drive from the OBX so much easier, I don't think I'll be using our SUV or minivan for the trip any longer.

    So, play it safe, or get closer to the house for a faster charge?

    Ask @Btr_ftw

    I'd rather not risk it but 12" isn't a big deal. I go through puddles deeper than that.

    If you go fast enough you might not sink (lol).

    Not sure how to go about doing that?

    I know the battery is sealed, but would you worry about anything getting into the cooling system?

    I'm hoping that extra inch or two with the SAS would keep the lower bumper from catching on any rocks.

    We've definitely tried the "fast" route - it's pretty amazing what a Toyota minivan can go through... or rather you don't want to get between a Yoga class and my wife:

    I've also lost the lower bumper on a Honda minivan when I didn't see the slush forming under a thin layer of ice. Plenty of interesting crossings over the 15 years we've owned the place!

    If there are holes, I would go to rockery and order delivery of river rocks or whatever size that can fill the dips. That might be a more practical solution then building a small bridge. Even with higher suspension I suspect you wouldn't want one wheel to go over a hole big enough to cause the car to get unbalanced.

    Never tried this so just offering an approach.

    Dayam.... ;) I think my concern would be, rather than the depth, how stable/hard is the creek bed? Car is *pretty* heavy. If it was that water over a highway, perhaps. After I've had the car for a few years. :cool:

    I've had a little experience driving in water here in Vegas. We get the occasional gully-washer that floods the streets with fast-flowing water. I've driven thru water that was ~4-6 inches deep (@ Trop & Rainbow) while driving 20 mph with no ill effects although the force of the water slowed me down to a crawl. And once I drove thru an intersection with water flowing so fast that my 90D was pushed sideways several feet (@ Charleston & Durango). Definitely got my pulse racing.

    OP has driven similarly heavy cars in the past. Given the last picture with substantial water flow, this seems a more ideal time to attempt it.

    Yes, as croman notes, it's a pretty stable bed. I would spend some time moving the larger rocks around though, as you can make it better by filling in some of the low spots and moving any unstable rocks out of the way. Most likely would only attempt a crossing the summer and fall when water levels are lower. One good spring storm upstream and we'd be trapped. Ice in the winter makes it super sketchy - we've even been stuck in a Range Rover. At least the town we are in, "Headwaters" lives up to it's name as there's only a few miles to the north / south continental divide, and we don't get extreme flooding as a result.

    I seem to recall reading a thread a while ago (I think it was in the rebuilding the flooded salvage tesla thread) that someone mentioned that there are some parts on the drivetrain that have holes at the top, but no holes on the bottom... so if water gets into these parts it just sits in there with no way to drain. Unfortunately I can't find that comment again right now. But if you do want to ford that stream you might want to do a bit of research to find out exactly what these parts are and how high off the ground these holes are.

    I found the post. In post 219 of this thread...

    Repairing a Flooded Tesla Model S : HOW-TO

    Ingineer said:

    This is what would scare me the most about trying cross a stream like that. If you can figure out just how high the water has to be to enter the drive unit and the stream is well under that, then maybe, but even so I would worry about water splashing up and into it.

    Maybe some lengths of moderate diameter galvanized pipe side by side oriented to let the water flow through the pipes.

    After reading that thread... I think I'm going to keep my Teslas high and dry!

    It's possible, but hard to do something temporary that's easy to remove, and anything permanent would get washed away unless it was fairly substantial. We get a pretty good flood every few years, usually from hurricane remnants that hit the mountains.

    Clearly you need to get an attachment like this for your model S

    This I gotta see. Please do it for science and take video.

    Newer models have a valve on top of the inverter that reduces the chances of letting water in.

    But, the pack has vents which can and do sometimes let water in.

    And, if your pack has ever (ever) been removed, there is a design problem where the gasket around the pack's main contacts to the car can fold inside the opening. (the contacts hole is too large, and/or gasket is too small) Water gets in and you are plagued thereafter by "Car Won't Start." (Insufficient resistance between + and -) If water stays in long enough the contacts will de-electroplate and corrode.

    The only solution is to pull out the whole rear subframe (with motor, driveshafts, suspension, etc), and try not to electrocute yourself when disconnecting the HV lines...
    then DROP THE PACK (yes, drop at least the rear of the pack at least 4")...
    and clean/dry the contacts male and female. If corrosion or de-electroplating, replace the contacts or die. This is true for all models at least up to 2016, and maybe later ones too.

    I speak from direct experience.

    (I was also replacing leaking oil seals on the diff, and changing the oil like we ALL should after a year with these cars)

    The problem. You can't really see the folded-in gasket in this pic, but you can in person. It's all along that front edge.
    [​IMG]

    There is no way to remove and dry/clean the connector without damaging it, or dropping the pack.

    (Shhh... don't tell Tesla about this design flaw. We're not supposed to know)

    This has been a public service message by your friendly FreeAnons.


    PS- @calisnow, the reason that rape is a reasonable gamble for some men, and has been through the millenia, is that it requires such a small investment by the male. The violation and consequences to the female are of little concern to those who pathologically lack empathy.
