Bizarre regen/brakes issue!

[EVDRIVER]

Like a drained battery, I would not be surprised if this never happens again.

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

Well, to be honest, I didn't think it was interesting at that time, I was just worried that something gone wrong with the brakes. That was the most uncomfortable part actually where I had to apply more pressure to the brakes, hence I could not start the car on the first attempt by applying normal pressure to the brakes. Software bug? In any case, if I ran into this again or find a way to reproduce it I'll update, but until then it's just a "fluke"... like a heater problem that I had a few weeks ago...

Something that causes the brakes to require MORE force than normal seems like it would have to be related to the brake booster or ABS. I've had ABS failures (false "ice' detection) that turn the brake pedal into a wooden block.. requiring herculean strength to press.

A total failure of brake boosting could also feel like more force is required.

Seems like something somewhere would have logged an error code. Me, I'd bring it to the dealer, exhibiting or not, and have them read out everything. Brakes -- not something you want to mess with.

Btw, just to add another observation, I did hear one clunk as I was driving...

I wonder if IBELEAF's "more force" might be related to an odd thing I have been noticing. Sometimes, maybe one time out of three, when I first get into the car and push the brake pedal before hitting the start button, I feel a "catch" in the pedal. It stops at about the depression where it would normally start to cause some braking if the car was powered up. It's a sharp stop feeling, like it hit something metal. But in my case it then releases without much extra pressure, and the pedal does down quite a bit further to the firm cushioned depth that I am used to feeling when the power is off.

Thanks for reporting your "wierd-brake" experience. Do go get the codes (if any) read by a helpful dealer.

However, we can all be more watchful for this "feature".

Like the "Teakettle Syndrome" by "starry" (apparently turned out to be a stuck/defective relay in (or associated with) the battery pack that powered-on just the Heating Element, only while charging), until we can give Nissan's EXCELLENT Task Force engineers something to work on, they cannot fix it and suggest improvements to Japan.

Absolutely. This needs to be "officially" reported to Nissan right away. Get thee to a dealer.

I don't know if it's related or not, but I've sometimes noticed the brakes are inexplicably significantly more grabby than usual. This has happened to me several times and I've been unable to figure out a pattern...

[garygid]

I experienced the strange, almost "grabby" brakes ONE time,
with the pedal seeming to go much further down than usual.

MAYBE it was the ONE time that I heard what sounded like the fans
coming on as I turned the car ON for the first time in the morning.
As I started moving backwards, the fairly loud "fan" noise quit.

[IBELEAF]

Yes, I did notice "grabby brakes" a few times at very low speed, but this was quite the opposite experience.
