Canada Investigating Potential Nissan Leaf Brake Failures

Canadian officials are looking into possible failures with Nissan Leaf brakes in severely cold weather.

Transport Canada, similar to the U.S-based National Highway Traffic Safety Administration (NHTSA), is a government department tasked with overseeing on-road safety policies and regulations.

In February, Transport Canada announced that they are opening an investigation of Nissan Leaf “brake system malfunction in severe cold temperatures.” The investigation covers 2013-2015 models.

While NHTSA hasn’t started an review of its own, several complaints over Leaf brakes have been submitted on its website by owners.

“Whenever outside temperatures are below +/- 38f, the regenerative brake system behaves very aggressively in the sense that the slightest use of the brakes results in a very jerky behavior of the car, braking very abruptly and hard,” stated one complaint filed last month for a 2014 Leaf.

“Usually, a second tap on the brake resolves the issue temporarily, but the symptom comes back soon after.”

Another owner complaint for a 2015 Leaf said:

“The brakes did not respond as normal on a cold snowy day. The tires did not slide and it was not a hard braking situation. Multiple times throughout the day, the brakes were not engaging properly.

“The condition went away the next day; a warmer day.”

None of the other complaints on NHTSA for the Leaf brake system linked problems with cold temperatures.
