[Caevlist] ? on 2011 Nissan Leaf brake firmware upgrade

[Matt Bierek]

Kirk,

When you find out anything please post it for us.

My 2011 has had this issue since it was new and the shop has never
come forward with any solution. The “grabby” is also referred to as
“snatchy” on some forums. The general consensus seems to point
to an issue with the switchover between regen and service braking
being too abrupt.

The other, and more frightening, issue is that there are times when
I will be sitting in park with the brake pedal pressed, then switch to
drive and the car will begin moving even while the pedal is under
pressure. I have to let off all the way then push again to get it to
stop. When I am in the driveway I have to react quickly to avoid
having to replace my garage door!

Subject: [Caevlist] ? on 2011 Nissan Leaf brake firmware upgrade

I've got a used 2011 Leaf with sometimes grabby brakes at low speed.  I recently discovered that there was a Nissan TSB firmware update that supposedly helped with this sort of problem.  LeafSpy lists my brake ECU as a 3NA0A, does anyone know if this is a pre or post firmware upgrade version?

More generally, is there information somewhere that documents the ECU versions for a 2011 SL so I can tell if the brake controller, or anything else, might benefit from a firmware upgrade?

Thanks,
