Some Nissan Leaf Owners Say Their Leaf Brakes 'Snatch' at Low Speed, Here Is Why
Here is what some Leaf owners replied to her in the group about Nissan Leaf's brake problems on low speed.
"Yes. It jumps between regenerative and conventional braking and the transition isn't always smooth. It can be dangerous if you are pulling up behind another car and all of a sudden your rate of deceleration lessons without you reducing brake pedal pressure," replied a user named Darren. He also added that he has never experienced a pulsing (warped rotor feel), but the regen suddenly disengages instead of tapering off as you get slower and it can be quite disconcerting.
Warning about Leaf brakes
"Be careful at low speeds trying to stop with regen only, if you happen upon a pot hole or oddly shaped grate. Regen kicks off leaving you without any stopping power because you aren't using the brake," wrote Nissan Leaf owner named Matthew.
Number of people in the group discussion complain about brakes of Nissan Leaf at low speed. Some say it's the same feeling as having warped brake discs and it's terrible. Other Leaf drivers wrote that they put their vehicle into N and lightly brake. I am not sure how safe is this and is not recommended.
"Pedro Gonzo This past winter it happened to me a lot. Now that the weather is warming up it hasn't happened yet," writes Pedro. But to this, a user named Jimmy replied, writing "don't chance it, replace your 12v lead acid battery. It happened in winter because the battery can't deliver as much current in cold temperatures, but is a sign of impending failure."
A group member Bill says "make sure you have all the firmware updates for the car. Depending on the year, there have been refinements to the braking." He also added that their 2013 Nissan Leaf needed a brake firmware update. "The dealer should be able to check their computer and tell you if yours needs an update," he wrote.
Replace 12v Battery for Better Brakes
Others suggested replacing your 12v lead acid battery ASAP if you ever experience momentary loss of brakes. "Make sure you have completed all brake recalls and service bulletins for your Leaf," wrote Jimmy.
Stopped at Light and Nissan Leaf Suddenly Moving Forward
" I have a problem where I'm sitting stopped at a light with constant pressure on the pedal, and suddenly the car starts creeping forward, making me jump to hit the brakes harder and stop the car," reported reported at least 2 members, Brian and Jimmy.
Jimmy then wrote, "Do the brake pedal recalibration. Come to a complete stop turn the traction control off press hard on the brake pedal for 30 seconds and turn traction control back on. That will recalibrate the brake pedal force for your strength."
People complains from dealerships about Nissan Leaf brake problems
When I posted this story on SF Bay Area Nissan LEAF Owners group on Facebook. People confirmed the brake problems with Leaf. The group is a public group. A User named Kelly Carmichael, wrote that he is already tired for taking his Nissan Leaf for the Nissan dealership for the brake TSBs. "I have been 7 times. The dealer doesn't know what to suggest anymore other than replacing the entire 'controller,' which is basically the entire block of metal under the hood. It costs $7000 dollars and no guarantees that it would solve my issue," Carmichael writes.
It happened to Bill Tomcofic too. He drives a 2011 Leaf. "When it did it was always immediately after charging up to the tippy top of capacity. My theory was the controller sensed that there was nowhere to regenerate to and so it gave the brakes a bit too much to compensate to be on the safe side. But what do I know?" asks he.
Julien Pierre writes in the same place. "I had problems with the brakes. The car would shake every time i would brake at a stop light or red light. I knew it wasn't normal because it didn't do it during the guest year. Living on a hilltop, somehow the brakes got a workout. Dealer could never fix them properly. Was glad to return the leased car."
Dave Davidson has had the same issue and has a solution. "I've had it happen on slick or rough roads. If one of your front wheels lose traction, the regen will kick off to prevent skidding. The first few times it was really scary until I figured out what was happening. Now, if I'm on a road where I think I might lose traction, I use D instead of B. By the way, my Volt does the same thing," he writes.
