5.6% of complaints about the 2012 Nissan Leaf came in the first year, which is unremarkable for a 2012 vehicle — around the middle of the 201 model-years on record. The median complaint arrives at 4.5 yr in service. The most-reported system is service brakes (22 complaints), typically at 2.8 yr or about 19,400 miles.
DURING EXTREME BRAKING ON UNEVEN SURFACE, LOOSE GRAVEL, OR SLICK SURFACE, THE ANTI-LOCK BRAKING SYSTEM (ABS) ENGAGES (AS EXPECTED). HOWEVER, ONCE THE BRAKE PEDAL HAS BEEN RELEASED, ABS FAILS TO RELEASE THE BRAKES PROMPTLY. THE ADDITIONAL RELEASE DELAY CAUSES GREATER-THAN-INTENDED BRAKING, AND POTENTIAL FOR BEING REAR-ENDED (STRUCK BY FOLLOWING TRAFFIC). *TR
