Today, while driving home, my brakes did something really weird. I would tap them softly, like I usually do to slightly slow down, and at first it felt normal, but then the regen braking maxed itself out, even though I did not change pressure on the pedal at all. From that point on, even just tapping the pedal causes the car to lurch forward as the regen braking maxes out.
This made going down a hill very difficult, because every time I even tapped the brake, it maxed out the regen braking slowing me down drastically. I had to "pump" the brakes by just tapping them to prevent me from coming to a quick stop. Strangely, after turning the car off for about an hour to eat and starting it back up, the issue was gone for about 10 miles, then came back same as before.
Both times, there was no warning tone (either the standard ding or the critical ding), just the orange wrench on the left screen and the "See Manual" message.
I know its regen braking and not service brakes because I have a scan gauge, and was able to watch my current to the battery spike to about 120A just tapping the brake. There was no lower current about at 55 mph, no matter how softly I tapped the brake. If the brake lights came on, I was max regen braking.
I'm going to get it to the dealership ASAP, but was wondering if anyone else had experienced anything like this before. I'm a little worried about driving it on the interstate if every time I even tap my brakes, its going to cause my car to nose dive with the amount of regen braking force it applies.
