What 63 owners told NHTSA about the 2018 Nissan Leaf (40 Kwh Battery)

Car was descending towards Kailua on the [XXX] on Oahu, HI. Dash lit up with warnings and acceleration and brake pedals stopped working. Brake pedal went to the floor with erratic pulsing sensation and very little brake power. Driver drove car into jersey wall to slow and stop vehicle. Battery state was 60% and battery was replaced under warranty about 1 year ago. While waiting for tow, powered on vehicle and symptoms remained as far as I could check. Brakes had no power and had to use ebrake to keep vehicle from rolling. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The incident occurred at a stop sign where I was waiting behind one other vehicle. The vehicle ahead of me accelerated from the stop sign to turn into traffic, but abruptly slammed on their brakes. I had began accelerating up to the stop sign and was unable to stop before impacting the car in front of me. As soon as I saw the vehicle was braking, I immediately slammed on the brake pedal. Braking did not immediately occur. My wife said she was afraid that I had slammed the gas pedal because she could hear my foot hit the brake pedal and neither of us felt any braking. The Nissan Leaf was in Eco Mode and ePedal at the time of the incident. I believe that the transition from regenerative braking to mechanical braking delayed the stopping of my vehicle. We were lucky that this happened in a very low consequence situation, but if this happened with a pedestrian or at a higher speed where emergency braking is required, this delay in braking could be dire. In addition, this vehicle is equipped with automatic emergency braking. I have heard this feature go off before in this specific car when a car is braking faster than I am. In this case, the alarm and assisted braking did not go off, despite a car stopping within extremely close proximity.

I was pulling slowly into a parking spot. The vehicle accelerated all of a sudden on its own very fast. I slammed on the brakes and the vehicle did not stop. It ran us on a sidewalk and crashed into a pole. Luckily no one hurt. Progressive is calling the car a total loss, but they have done nothing The car is still at a parking lot near the crash. Nissan is also doing nothing. I feel that I deserve better treatment. I have a good driving record and my rates are going to go up. I have not been offered a replacement car. The car is very dangerous and I would never drive another Nissan

I was stopped at a light, in a long line of cars, my foot on the brake, a few feet away from the car in front of me, and the same in back. All of a sudden, the car started moving, accelerating, jerking forward. I was shocked, pushed down on the brake, nothing happened. starting pulling the car out of line because I was going to hit the car in front of me. I was pumping the brake, and NOTHING HAPPENED. Clipped the car in front's rear left bumper, wrecked my front right bumper. Finally pulled into the turn lane and finally the brakes caught. It was like someone had taken a gizmo and turned on my car (like the OnStar mess a few years ago.). Nothing like this has ever happened to me, in any car, including this one, until 5/12 at 2:00 pm. It was terrifying.

THIS NISSAN LEAF HAS AN EZ-PEDAL FEATURE. WHEN ENABLED, TAKING YOUR FOOT OFF THE ACCELERATOR SLOWS YOU DOWN QUICKLY UNTIL YOU COME TO A FULL STOP. AND THEN THE CAR DOES NOT MOVE. AND THIS NON-MOVEMENT DOES NOT REQUIRE DEPRESSING THE BRAKE. WHILE A CONVENIENCE, THERE IS A DESIGN FLAW. WHEN ENABLED AND THE CAR IS STOPPED (BUT IN DRIVE), THE BRAKE LIGHTS DO NOT COME ONE. IN CONTRAST, WHEN STOPPED USING THE BRAKES, THE BRAKE LIGHTS ARE ILLUMINATED. THIS IS A SAFETY HAZARD! DRIVERS APPROACHING FROM BEHIND DON'T EXPECT A STOPPED CAR TO NOT HAVE BRAKE LIGHTS ON. THEY MAY REALIZE RATHER LATE THAT THE CAR IS STOPPED. IN OTHER WORDS, THE VISUAL CUE OF "BRAKE LIGHTS ON MEANS CAR IS STOPPED OR SLOWING DOWN" IS NOT EVIDENT. WHICH CAN LEAD TO MISTAKES BY DRIVERS WHO ARE NOT PAYING FULL ATTENTION. THIS HAPPENED TO ME RECENTLY. I WAS STOPPED BEHIND A CAR WAITING AT A CROSSWALK. ON A 3 LANE 40MPH STREET, WITH NO LIGHTS OR STOP SIGNS FOR A MILE. A FAST STRETCH WITH NO EXPECTATION OF STOPPING!. I, IN MY LEAF, HAD EZ PEDAL ENABLED. I WORRIED THAT SOMEONE MIGHT HIT ME, SINCE I WAS STOPPED IN A PLACE THAT IS UNUSUAL TO STOP IN. AND 15 SECONDS AFTER STOPPING I WAST REAR ENDED! NO PERSONAL DAMAGE, BUT $1500 IN REPAIR (AND MORE FOR THE CAR THAT HIT ME). SINCE I WAS NOT AT FAULT, I WILL GET FULL INSURANCE. BUT IT IS NOT A GOOD THING! I CHECKED LATER - AND INDEED THE BRAKE LIGHTS DO NOT GO ON WHEN THE CAR IS STOPPED IN EZ-PEDAL MODE. THIS NEEDS TO BE RESOLVED! I IMAGINE THIS IS A SOFTWARE UPDATE. I SUGGEST THAT FOR CARS (LEAF OR OTHER) IN DRIVE, WITH EZ-PEDAL ENABLED: WHEN THE CAR IS FULLY STOPPED THE BRAKE LIGHTS MUST GO ON. AND, WHEN THE CAR IS DECELERATING QUICKLY (WHEN YOU TAKE YOUR FOOT OF THE ACCELERATOR WHILE MOVING), THE BRAKE LIGHTS SHOULD GO ON. THANKS. I COULD OF PUT ON MY EMERGENCY FLASHERS, BUT IT IS NOT EASY TO THINK OF SUCH A TRICK ON THE FLY.*DT*JB *DT*JB
