One pedal driving not working

[SoodTheDude]

Hoping someone else has had this issue, my one pedal driving no longer works, all the car will do is coast, will not display that it’s braking at all like before unless you tap the brake and it won’t “aggressively” slow down like before either, the normal feedback given isn’t there either, anyone had any experience with this?

If I had to guess, it would be because either your battery is full, or its too cold for regen.

The amount of energy fed back to the Battery using regenerative braking can depend on the current state of the Battery. For example, regenerative braking may be limited if the Battery is already fully charged or if the ambient temperature is too cold.

Battery wasn't full! Also for the too cold for regen, I turned on HVAC from phone so battery would warm up and I did not get a regen is limited message

HVAC does not warm the battery if I understand correctly?

Turning on climate should also turn on the battery heater if the battery is also cold( confirmed by the 3 bacon strips next to the state of charge indicator on the home page.

@SoodTheDude You're not the only one to report this issue in the forums lately. I suggest filing a service request. If regen comes back reliably then cancel.

(Regen has been working just fine on my Model 3, I've not sensed any reduction in it aside from expected situations of cold or full battery, but I'm not discounting what you're experiencing.)

I have also noticed reduced regen braking lately. Battery isn't too full and I precondition before driving. Temperatures here have been in the 40's and 50's. I began to notice it after updating to FSD 10.9. I'm on 10.10 now, still having the same issue.

You are not the only one. I have noticed this after 2022.4.5 software update. My car behaves like it’s 100% fully charged. It takes much longer distance to slow down the car and I am using my brake more often. Also, car behaves strange with a slight jerky movement when I release the accelerator. Car doesn’t slow down immediately and there is some delay reaction to regen. I really don’t like this.

My guess is that the added Regenerative Braking in Autopilot in this new update is messing up the one pedal operaction.
Another software update failure.

@RyanS File a service request for the issue! Get it escalated. It seems like a decent number of Model 3 are affected, but far from every Model 3, so I think there's risk Tesla won't notice or prioritize this issue unless the affected owners escalate it (via service).

I plan to mention this to a SC staff tomorrow since I am taking my car in for a service for an unrelated issue (Front left safety restraint system fault issue - I expect this will be the next safety recall item)

Unfortunately, my car is out of warranty so I don’t expect much from Tesla SC unless I pay $$$$.
