Regenerative Braking System not Optimal warning

Regenerative Braking System not Optimal warning

My brand new M3 duel motor recently started flashing the above message on my screen. I haven't noticed any difference in braking performance while this message is active. Please advise.

Yes. It happens when the temperature is in the 50s.

Where are you? Is it cold outside?

Since you are using your motor to "duel", you will receive all enhanced warnings.

I have been seeing the same message whenever the temps are cold, which they often are in Colorado. There is no performance impact so I have assumed it means less energy is being returned to the batteries in the cold weather (and I have definitely noticed my range is impacted by the cold weather).

That’s the first I have seen it phrased that way. Typically I only get a regen warning if Regen has been disabled due to the extreme cold. This is on my MS. Perhaps this is a Model 3 thing or part of an update I ahven’t received yet.

We also get the limited reven message everyday when descending from our home st 2000ft to sea level. We’re in Hawaï, so temp not below 50.

We limit our battery to 80% max per Elon Musks recommendation for long battery life, and never discharge below 20% for same reason. His batteryexlert actually prefers keeping between 30and 70%, but that’s not very practical.

Will double check to see if regency limit only cones on as battery is near our set limit—thanks for the tip!

Starts in mid to high 50s, overnight temps. Excessive regen from descents can trigger limitations, but that does not show up from the get-go.

Display of this warning is not consistent in my limited experience. Look at the graphic that defines your regen capacity, and don't pay attention to the warning.
