Feeling a "Cold Draft" from Windows and Front

    Does anyone have this with their X? I guess I haven't noticed it before because I'm usually wearing a pretty heavy Parka, but had a longer trip yesterday so decided to take off the jacket, and man, the car was freezing.

    Drove from Toronto (Canada) to Buffalo, NY (~200km/125miles) on a fully charged (100%) X75D.

    Temperature was -7c/20F - Otherwise clear driving conditions

    I previously had passengers complain about this when sitting at the back but I thought they were exaggerating.

    However, it was just way too cold to sit there without the jacket due to a really cold breeze coming from the windows, almost like they're not "Sealed" properly. Felt another draft coming from the "front" of the vehicle. Specifically noted that the area under the touchscreen was cold.

    Is this normal for Teslas? I've never experienced such things in any other vehicle I've driven.

    I normally have the climate control running at about 20c/68f, but had to crank it up to 27c/80f just to keep it "bearable".

    Also, I've been noticing a "MAJOR" change in how long my car lasts and the "wh/mile" I'm getting.

    On the way from Toronto to Buffalo, my car was averaging 490 wh/mi at speeds between 55mph - 70mph - 100% on autopilot with 0 traffic - complete highway driving, so there was no stop/go outside of "at the border". Climate control was at 68f for the most part but at 80f for a little bit, with seat heater on at "1" for 2 seats

    On the way back from Buffalo to Toronto, my car was averaging 510 who/mi on speeds between 55mph - 75 mph (most of the trip, increased to 80mph near the end of the trip) all on autopilot. Climate control at 68f for the entire trip with seat heater at "1" for 2 seats. 0 traffic - complete highway driving


    I did a similar trip the night before as well, from Toronto Canada to Niagara Falls Canada (didn't cross the border this time), and had similar results.

    On route from Toronto to Niagara averaged 515 wh/mi (after supercharging at Grimsby) driving between 65mph - 70mph complete on autopilot with climate control at 68F, 0 traffic and no "cold weather" features enabled (barely had enough juice to make it to charger) - complete highway driving.

    On route from Niagara to Toronto averaged 516wh/mi (after supercharging at Grimsby) driving between 65mph-75mph complete on autopilot with 1 seat warmer at "1" and climate control at 68F, 0 traffic - complete highway driving.


    Other details:
    Using 19" Pirelli Scorpion Winter Tires (purchased and installed from a Tesla SC). Tire pressure per dashboard for all tires was 42psi.

    Car was "completely warm" (in the sense that regen braking was not limited like it usually is in cold weather)

    Temperature on both days was similar -7c/20f

    Wind speed was "average" and I guess wouldn't matter since if it was bad one way, the return (both times a couple hours later) should have benefited, but it did not by much

    I think I have the exact same issue as you... not so much cold air from the windows, but right under the touchscreen, I've been feeling a cold draft from the front, so my feet gets super cold.

    My wh/mi gets noticeably higher going from 5C to -5C, as the temperature in Toronto these days. Gets closer to 500wh/mi, with 19inch Michilin xi2 winter tires.

    Speaking of which, the other day I saw a blue MX driver waving at me around richmond hill area... couldn't be you could it? lol

    Hmm so I'm assuming this means there's definitely something wrong with the seals around the windows in my vehicle? Trading it in for another X (w/ autopilot 2.0!) in a couple weeks so glad that'll fix itself.

    A little disappointed to hear that the 500wh/mi (~320wh/km) is normal based on your experience. Really sucks for the longer drives.



    As for the car being in R. Hill, that might have indeed been my car if it was 2 weeks ago haha. I let my brother drive it there for a week, may have been him :).

    if you are having wind noise or air leaking in make a visit to your service center, poorly fitted window gaskets are a common issue and usually easily fixed.

    Front side window gaskets received some attention at a service center visit for the sake of wind noise. On very windy days with I do feel a breeze from the windows but only intermittently with gusty cross winds.
    Check that your rear passengers are not getting cold air from the rear HVAC through the B pillar vents. The air is cooled as it travels along the side of the car to the vents. Prewarming the channel with HI temps and hi fan seems to help. SC put some insulation in when I (my passengers) complained.

    The rear passengers do indeed get cold air when cars in "Range Mode" but other than that, there's also a draft from the windows.

    I'm hoping this is corrected in the next car.

    The problem is -7 c is not really all that cold.

    I read some people pulling the large sun visor (not sure what you call it in an x) forward and they said that helped a lot.

    It's why I'm a little disappointed...a couple years ago the month of February was -30c the entire month (in toronto)...this car probably wouldn't even be drivable in that weather?

    Bjørn Nyland (Teslabjørn) insulated the top of his windscreen, helps a lot.

    My advice is to bring in evidence to the Service Center.

    I recommend purchasing an thermal Camera (like link below) and take pics of the cold entering the vehicle at speed. Then have them take you for a ride in a demo and see if the thermal signatures match.

    (Seek Thermal Compact Imager for Android - - Amazon.com)
