Regenerative braking control missing

[BioSci]

I'm a brand new owner, so if I'm doing something terribly naive, please be gentle. I just got my 2020 MS LR+, and for the life of me I can't find how to change regenerative braking between Low and Standard. As far as I can tell, the option isn't on the Controls > Driving screen. I remember seeing that during the test drive (of a different MS). Here's a photo of this screen on my MS, without control settings for regenerative braking.

For reference, I'm on 2020.36.11. Tried resetting the MCU and the whole system, without change. Is there something obvious I'm missing?

You are on the correct menu screen.

Could it be dropped altogether with the latest new Teslas or this is just a software menu bug that will be corrected at the next update?

I wouldn't want to be driving my Tesla on ice without the ability to lower regenerative braking. Cutting the throttle quickly in an ICE car can be bad enough for stability in low-traction (or worse, split-mu) driving.
With full-on regen in such a situation, it's almost like slamming on the mechanical brakes.
Worst case would be in an RWD car, where the fronts continue free-rolling and all regen is in the rear. It could be kind of like yanking an e-brake handle (not that I didn't do that in my younger days in empty parking lots and cheap crappy cars.)
Maybe Tesla wants to see how good their stability control really is this winter?

This reminds me - I need to get a good jack and change onto my 19s soon. It was 39F this morning.

Try scrolling on this page to see if there is another slider hidden below that line.

Report this as a service appointment from the app. A technician will call and you will probably be pushed software to reinstall. Something didn't configure properly. Also, try a reset by holding both steering wheel buttons in until the dash goes dark. That may fix it.

Tried that on every page to see if it had moved. No joy. Also, I think another setting is also missing: Range mode. That's less concerning, but I agree that this must be cleared up before we encounter slippery weather. In New England, that's never far in the future.

This worries me a lot. Last year I had both options enabled while (inadvertently) driving on an icy road and I ended up spinning the car while climbing up a hill in our holiday vacation

Did you reboot the system, as I recommended?

Yes, I tried both rebooting the MCU and also rebooted the entire system for 30 sec. No joy. I did follow your advice to contact Tesla service. They scheduled a home visit in 5 days, but I expect this can be fixed online.

I haven’t had that option either on a May 2020 built Model S LR+ I thought they just removed it. Please post of this is resolved. I have cut all power to my care before and still no luck.

 

[derichio02]

Definitely had this on my 3

P85D owner here, both Range Mode and Regen controls are still there after the update.

I'm on the same version, and not only is Regen control gone, but also Range Mode setting.

Super small sample of course, but per @derichio02 post it kinda looks like this is only affecting LR Ravens?

 

[derichio02]

Same version here too. Hmm I wondering if those settings appear if we switch from Hold to Creep or Roll. Can test in the morning

I believe the ability to adjust the setting was dropped on new cars to achieve the latest EPA range rating.

I can confirm that. I was visited by a mobile tech today, and the final answer to the missing regen control is that as of June 2020, all Model S vehicles manufactured no longer have the ability to switch regenerative braking to Low. This was also put in writing on the service invoice.

TL/DR: Regenerative braking control is no longer available in new Model S cars.

With regards to the missing Range control, the tech could find no information that it was dropped; a bug report is being forwarded to Engineering.

...Regenerative braking control is no longer available in new Model S cars...

I wish Tesla can list all the changes on the web page so we don't have to bother the Service Department if something is expected to be missing due to progress.

Removing a configurable setting for the sake of improving EPA rating feels more like a step backwards than progress to me

It really isn't. The car detects the friction loss and immediately lowers the regen if necessary. It's no different from slamming mechanical brakes with ABS.

Worst case would be in an RWD car, where the fronts continue free-rolling and all regen is in the rear.

Been there, done that. Also that is no problem. Even in snow and ice (we're talking Canadian winters here) I never had an issue because the rear wheels would never lock up.
