Bizarre regen/brakes issue!

Earlier today my Leaf got "stuck" from the start in some sort of brake/regen mode and brakes were much harder to push. Basically, if I let go of accelerator on the flat surface my car immediately would start braking with 4 regen bars. I drove like that for couple of miles then stopped and powered the car off thinking that would go away. Suddenly another issue, I could not turn the car back on because it kept asking me to push brakes. After several tries I finally got it turned on by pushing brakes as hard as I could and the earlier issue went away... So, got me a little worried and I was trying again to reproduce this issue again, but no luck so far.

Now, before it happened I can't exactly recall if I did anything, but I do have some details. I parked the car backwards and turned it off bypassing P button as I usually do and I think I had my foot on brakes for about 5 minutes as I was sitting in the car waiting for my wife. Then I turned it on and discovered this issue immediately, which freaked me out at first.

Kinda sounds like eco mode.

You must always push the brake to start the car.

It sounds like you need to do a fresh install. Did you back everything up?

i am aware of that, but in this case it required more force then usual

Re: Crazy regen/brakes issue!

Sounds like you unlocked super regen mode. How did you do it? Was it a secret shifter combo? Left, left, down, down, left, down?

Seriously though, sounds like there is an issue with the brake booster so it was kicking in more regen as a safety method to slow you down. Pretty smart. I would like to find out how to trigger that mode on demand. I bet a relay or resistor could could do it. Any more info on how, when it kicked in? Speed, drive mode, charge level?

The brake sensor switch is on or off, pushing harder does not make it contact more:)

Re: Crazy regen/brakes issue!

The description sounds very interesting. I'd certainly like to get into that mode, only with fully-operative (normal pressure) brakes.
