Snow and parking

I'd like to see that video... it looks like it rolled and not slid because there's no snow buildup in front of the wheels and you can see the tire tread marks.

Great video, watched it at least 10 times. The back wheels are definitely sliding and locked, but the front wheels are definitely turning/rolling. The treadmarks that are easily visible on the pictures must have been when you backed up.

Interested to see what BMW says about this.
I better go pick up my car before we get another recall.

Conscious now of travelling , parking and or waiting at the lights while on an incline in the snow.
Not snow tyres BTW but plenty of tread on them.

Thank for the message. I'm wondering if you have winter tires?
The iX is a heavy car...
I have just the opposite experience with winter tires.
I almost fell but the car didn't move on the slope.

Hi Hans , we only get snow for a few days of the year so I've not invested in them.

I'm missing how the type of tire matters here, as the front were rolling forward dragging the rear. Shouldn't all the wheels be locked?

Handbrake is mostly only the rear wheels.

Summer tires will slide like that. I see it all the time at ski resorts where cars slide sideways into each other in the parking lot.

Sideways is a slide. Rear wheels dragging is a slide. Front wheels rolling is a brake/motor not holding the car problem. Will think twice about backing up and parking on any hill.

Rear wheels slid in video. Even my Rubicon only has one rear wheel that locks in park unless I engage 4WD and then it's only one up front and one in back

You can tell the rear wheel didn't rotate by looking at the angle of the rim. Would be interesting to see a wider view showing the front wheels as well.

I had a similar experience yesterday. Parked car uphill in mild incline. Was clearing snow from an adjacent tennis court and observed the car spontaneously roll slide down the hill after about an hour. Back wheels locked but front wheels rolling. Alarm went off. Mild angina. Just missed two walls either side of the slope.

Was the front-end pointed downhill?

Front end up hill

I'm genuinely concerned now that the car is unable to keep itself from sliding if there is any reason for the back tires to have less friction than required (to counteract the car weight). I mean, if I'm on a steep hill and the street is wet...will the car slide?

Seeing as the alarm went off, did the drive recorder catch the movement?
