Regenerative Braking after 40.8 update

[SCarolinaM3Guy]

I got the 40.8 update yesterday. Prior to the update, my regenerative braking in standard mode was great. I noticed when I drove today, and the regenerative breaking wasn't nearly as strong, to the point I had to double check to make sure it didn't somehow get switched from standard to chill. Really feels virtually non-existent unless I'm going below 10mph and even then, it coasts much further than it was even yesterday before the update.

Anyone else that has the 40.8 update noticing their regenerative braking not working as well as it was before the update?

I thought that too. It could have been one of the efficiency improvements. More regen doesn’t necessarily equate to more efficiency. They may have determined a more efficient sweet spot.

I hope not. I really enjoyed the old regen strength. I'd give the 7 mile range improvement back if the gain means weaker regen!

It is getting colder, so maybe that is what is being felt.

So I just picked up a new model Y, downloaded 40.8 when I got home and the regen is super hard compared to my 3. And, there is no way to adjust it. Under driving, I have no braking regen section like I do in the 3. Is that normal? You can adjust it in the Y?

Tesla realized that they weren’t making enough money on brake pad changes, so made a little software tweak which would force us to use our brakes a tad bit more

Interesting, I haven't noticed any change in regen with the new software upgrade.
@pdxrunr , yes you should be able to adjust the regen. Sounds like something is "off" with your software.

Noticed the same thing today. It’s slight but i actually had to use the brakes in places I did not before

 

[captanzuelo]

Yes, a very slight change for me as well. There is a hill nearby that levels out at the bottom. I have always regen’d down to a stop. Now, I need to help it stop with a little braking.

I've had that issue for a couple weeks now. I am 40.8 but noticed it even before 40.3. It seems random but I also notice it more on slight downhill stops

Does everyone with 40.8 on their MY have the regen option? I just called Tesla and the reason I don't have it is they said they have removed that option and it's controlled automatically! And it's way to strong.....opposite of what I'm hearing from everyone else. Very strange.

Yes, I posted a picture of mine above.

Someone on Reddit let me know that when you charge to over 90% on the battery, the regen braking impact is lessened until you are back below 90%. That seems to be true as I drove it today and was at 99, and once I fell below 90% the regen seemed to be back to what it has been.

 

[pdxrunr]

Yes, I posted a picture of mine above.

Right, but I wasn't clear what model year your Y was. I assume 2020 now that it's been confirmed they have removed it for 2021. Such an odd choice to remove that.

 

[MY-Y]

Finally had a chance to drive with 40.8. The regen braking feels the same to me.

40.8 here - regen feels the same

Yes, mine is 2020. Yours is always “standard” regen? Always one pedal driving?

It is true. It’s in the manual. Below the speedometer the line will be dashed when it’s restricted.

is it possible with Fall upon us that in a number of areas its a little colder out - which will affect regen somewhat....?

I believe if you have "chill mode" on you cannot change it, so change it to standard mode, and then you can change regenerative braking...
