Every time I start my Model 3, I get a message on the screen telling me that regenerative braking is limited. When I'm actually driving, regen seems to work fine, though if my regen has been limited ever since I got the car I'd have nothing to compare it to. It's definitely less than on the Roadster, but I already knew it would be. My ambient and battery temperatures are not extreme. The battery is charged to somewhere around 80%. I have regen set to Normal. Nothing actually seems to be wrong, so I'm really wondering what's the deal with the message.
