Re: 2017 Leaf S, jerking, or skipping when coming to a stop only 62 miles

WHOA guys, this is a brand new owner of a Leaf. Don't go telling them to shift gears while the car is moving, or telling them to get new tires.

There are no gears to change in the transmission, so that is out.... "Jerking and skipping" may be the result of stopping on sand, leaves, or a wet, or rough road, which makes the car slip a bit until the car comes to a stop. This can happen especially when you are stopping as you are turning... OR it may be that the new brakes grab really quickly because they are new....

Drive the car for a few hundred miles so that the new brakes will soften up. If it still does it, go back to the dealer. This does not sound like a dangerous or defective situation... Keep us informed.

Who has suggested new tires or "shifting gears"? While non-LRR tires might improve things for the OP, I agree that it's mainly a matter of adjusting behavior. I was saying that the LRR tires on the Leaf and Prius may be making the problem worse, that's all. Many people tend to stomp on the brakes, and doing that with a Leaf isn't something that will work out well long term...

Hello,

I own a 2013 Nissan Leaf and experiences the same things.
It is for me a 'problem'.
I mean it is not normal for me that the regenerate system gives so much trouble while braking....
I have talked about it at my reseller at the first visit 1 month after the delivery and unfortunately, trying the vehicule, the technician did not notice it, I was sitting next to him in the vehicle.
Please for others stop talking about ABS, it is not the same car behalf when it is working and no it doesn't come from brakes too new or tires.
My leaf is a 2013 one and was not new when I bought it from a NISSAN reseller.
For the next visit of my car to them I will again ask for a tune up or system update regarding this as I expect a failure in the system.
For me it occurs in various situations and at very different speeds.
And it is upsetting me.

Regards

Don't know if this still applies, but for earlier LEAFs you could "re-calibrate" the ABS by pressing the brake pedal ALL THE WAY TO THE FLOOR, and holding it there for at least 30 seconds while the car is in drive.
I noticed you're still working with polymers.

I believe you also have to switch off the traction control first.

This used to happen to me in my 2011 often. I would be coming to a stop, and the car would jerk, causing my foot to jerk, causing the car to jerk, causing my foot to jerk.... the only way out of the loop was to either release the brake or stomp down on the brake, suddenly stopping the car. The "recalibration" mentioned above is the only thing that would help. I did not have to turn off traction control.

The traction control off thing may be for 2013 on, or it may have been an unnecessary instruction that got repeatedly passed on here.

What does this recalibration of the ABS do? How often do you do it, and why?

Searched for "ABS recalibration" and got nothing relevant.

I have had an unnerving brake experience infrequently: when braking at fairly low speed (happens around 10 MPH IIRC) I'll get a half-second or so in which braking power seems to suddenly decrease then return to normal. Doesn't feel anything like any ABS effect I've felt before, so I assumed that regenerative braking simply cut out for a moment. I need to do better at recording the conditions at which it occurs. I certainly don't like it, whatever is going on!

Going over a patch of rough road will do that. If this is happening it's normal. If the braking power gets reduced on smooth road, you have a problem.

I assume that the brake recalibration consists of the braking booster getting reset to factory parameters for degree and duration of assist.

I don't remember associating it with bumpiness. It happens rarely enough that it is always a surprise, and I don't feel like I have any way to duplicate it. I'll have to try harder to notice what the previous couple of seconds were like, and other conditions like speed, level of braking, etc.
