EQS 450+ STALLED IN MILD SNOW!
This morning after dropping my wife off at work, I was returning home, which should typically take 5 minutes. As it was snowing (mild), I was driving carefully, and it started skidding frequently. I reduced my speed to 10-15 mph. There is a slight incline on the way to my home. The car stopped and began to move at 1 to 2 miles per hour. However, all other vehicles were moving at average speeds without any skidding! It took me 46 minutes to move the last 0.5 to 0.6 miles to my home. I changed from comfort to sports mode and back and even from strong to normal recuperation, which made no difference. After about 40 minutes or so, the power improved, and I reached home. I called "me" Mercedes through the car, and they felt it could be due to summer tires, which will not have enough traction. I can't believe that having summer tires will reduce the power to move forward! I am not sure if Mercedes electric cars are ready for prime time yet! I noticed every other car driving quite normally, and sitting and moving at 1-2 mph in a luxury car wasn't very comfortable.
Did this happen to anyone? Is it the tires?
Thank you.

You are lucky you got anywhere at all. RWD and summer tires on ice! On a 3 ton car. No to be mean, but.....WHAT WERE YOU THINKING!!! You are lucky you didn't destroy the car running into a culvert or another vehicle. Even if its an AWD 450, driving a car with summer tires on ice is extraordinarily dumb.

The low power is the traction control system.Remember, even light snow when fresh can be as slick as ice. You can resolve the low power issue by turning the traction control off, BUT, youll slide that much more. When there is frozen precipitation I run the vehicle in eco which tames the torque by reducing power but the vehicle won't stall.

The traction control is in the vehicle settings menu, there is no button. Be safe.

Your initial post said you have summer tires. Suggest you look at the sidewall and see what you actually have. Shrugs

I just checked the tires. It shows they are made in Germany. Treadwear rated 300, traction AA, and temperature A. It does not say all-season or summer. I looked it up on the net, I could not interpret it with certainty that they are all-season.
I am hoping to get the snow tires tomorrow and install them at the dealership.
Thank you all for the input. I am for all-season or snow tires in the winter. That was not my question originally. I was curious if the tire type affects the electric car's power transmission to the wheels. I got the answer, BTW.
Thanks again.

I am truly sorry for not being specific and accurate. I think at this point what C4004matic said, "The low power is the traction control system. Remember, even light snow when fresh can be as slick as ice. You can resolve the low power issue by turning the traction control off..." seems to be the answer I got.
The car sensed that it was skidding (sensors were extremely sensitive, probably) and reduced the power to the wheels, and allowed enough power to go at 1-2 mph. The moment it reached the less snowy part of the road, it released more power, feeling it was safer now! I shall post my experience post-snow tire installation. If the problem persists or recurs, we must research the cause. I sincerely thank all of you for your valuable input!

What is the brand and model of tires that you have? Does your car have the AMG wheels? The low wear rating does suggest that that car is equipped with summer tires. Why they would equip an EQS with summer tires is beyond me.

We can only guess at why this was the case.
In fact, at the 2023 450v4 site just now, only summer tires are shown.

I plan to keep my EQS in SE Florida so I got summer tires. Did I make a mistake?

I have Summer tires on mine as well, 11K miles on them, and now into my second Winter (got it last January). I have had no problem with the Summer tires on wet or dry roads in cold weather, but have not driven the car on snow or ice.

I considered and should have qualified my comment for regions where there is cold weather. As has been pointed out above summer tires have **** traction in cold wet conditions.

No as the name implies they are summer tires which is to say they give better traction in warm conditions. The statement was based on the premise that summer tires are typically fitted to high performance cars to provide high cornering limits which doesn't seem applicable to an EQS use case given that high quality all seasons perform pretty well to begin with for normal driving. Now one could argue that in a warm climate region such as Florida or for an owner who wants to go through the exercise of swapping wheels semi-annually, the additional traction during warm weather could be considered safety margin in event that evasive maneuvers were needed.. This would be at the expense of replacing tires more often due to the lower wear rating.
