Has regen come back for you yet?
Well, this morning it was better. I had also switched back to Hold mode. So I am cautiously optimistic.

Has regen come back for you yet?
While testing my new winter tires I noticed for a moment when flooring it that this icon would show up:

I don't remember ever seeing that in any other hard acceleration before with the original tires. The roads were dry and clean.
I'm hoping you are right. I will report back in a couple of days to give feedback. At the moment, my regen is nearly non existent with all other conditions being the same. I'm using brand new Hakka 9 studded on a Model 3 RWD SR+. I thought the culprit was the latest software update, but if it's just the tire change then fine.
Truthfully, I find the winter tire regen reduction can vary between software versions.I just installed new Michelin x ice snow tires and am noticing the issues reported in this old thread.
Can someone summarize the latest news, will my regen return once the tires are "broken in"? Is the car learning the new tire configuration?

Truthfully, I find the winter tire regen reduction can vary between software versions.
I have my winters on (starting their third winter season of use) as of two weeks ago and the regen is reduced, but not by the really pronounced changes I felt back in 2018.
I just had X-Ice snows installed on our Model 3 a few weeks ago, and immediately noticed the same issues. Very little regenerative braking most of the time, and acceleration was much lower than normal too. I thought perhaps the tire shop had disconnected or damaged one of the wheel speed sensors, which (I've read) could make the computer unsure about the available traction.I just installed new Michelin x ice snow tires and am noticing the issues reported in this old thread.

I submitted a service request and Tesla sent someone out to check everything over. The tech didn't find anything wrong, but he did say that switching to tires with a very soft rubber compound can make the computer think it has less traction than it really does. This could be even more likely with brand new tires because the tread blocks are so tall and therefore less rigid (more "wiggly"). The tech said that the computer should recalibrate itself after driving around for a few days. He suggested occasionally doing some hard straight-line acceleration and coasting to help it recalibrate. I did that (when don't I?? ) but still found it took several weeks for it to improve. Now it's much better, I'd say 90% back to normal, but still not quite the same as it would be on all season tires... maybe that's a good thing though, since the roads will be slipperier this time of year anyway.
Another thing he mentioned, is that the issue should improve as the temperature drops because the rubber compound will become more rigid. I actually did notice that to be true a few weeks ago, but now regen & acceleration are normal-ish regardless of temperature.
So hopefully yours will improve too over the next couple of weeks. Good luck!
That's definitely a good point! In our case, it was still relatively warm out (15 C) so that wasn't the issue for us. We've had our Model 3 since Nov 2018 and we've seen regen affected a lot during two winters (both with stock all season tires). You're right, when the battery is cold there's almost no regen until it warms up.You sure it's not because your battery is cold? Regen can drop to practically nothing if so.
