I recently took my 2018 Leaf SV into the dealership for its 2 year service. They presented me will a bill for CDN$1,100.00 for a complete brake replacement. They said that the rotors were rusty and they had caused unusual and excessive wear on portions of the brake pads. On a two year old car still under warranty with 39,000 kms I was very disappointed in this situation.
I rarely ever use the brakes as I always use the e-pedal function. I believe that Instead of the brakes being used regularly as in an ICE car, the brakes on my car almost never get used, and they became rusty as a result.
I believe what is happening is that the e-pedal technology has created a situation where a conventional braking system using standard quality hardware that worked perfectly well on conventional cars is no longer suitable without improvements to the design to prevent premature rusting.
What Nissan needs to do is to inform owners of the Leaf with e-pedal technology of this situation. As the e-pedal technology is relatively new, it is probably only now becoming apparent that the brakes will fail prematurely if they are not used enough to prevent rust forming on the rotors. Using the e-pedal is supposed to save energy and therefore to save money. if this technology causes repairs of $1,100.00 every two years, it is not anywhere near a cost-effective solution as currently designed.
