2014 Nissan Leaf Brakes Problems

Your car's braking system failed completely when put in reverse, leaving only the emergency/parking brake working. The car rolled freely and nearly hit a structure, and the regular brakes felt like the ABS was constantly engaged, requiring you to stomp the pedal hard for any braking effect. Multiple warning lights appeared (brake warning, VDC, master warning), and the car continued applying power without you pressing the accelerator.

Your brake pedal goes all the way to the floor with no stopping power, and you hear an ABS noise when you try to brake. The Nissan dealer has suggested the ABS control unit may be the cause and wants to replace it for $2,200, but they can't guarantee this will fix the problem. The dealer has stated your car is not safe to drive. Fixing this will likely involve diagnosing and replacing the ABS control unit and potentially other brake system components.

Your car's brakes suddenly failed completely while driving at low speed, causing you to coast about 10 feet past a traffic light before regaining braking ability. The dealership diagnosed a failure in a major electrical component of the braking system, not the brake pads or rotors. You reported finding similar complaints from other 2013-2015 Nissan Leaf owners online. Nissan declined to issue a recall and said you would need to pay for the repair of the failed electrical braking component.

Your car's braking system has stopped working while you're driving, forcing you to use the emergency brake to stop. This malfunction has happened multiple times on city streets. Your dealer indicated the brake cylinder system needs to be replaced to fix the issue.

When you start your car, the brake pedal isn't releasing normally and feels unusually stiff. As you drive, the pedal becomes increasingly hard to press down, leaving you less room to move it before the car stops. Even after a dealer inspection that found nothing wrong, the problem has worsened over just a few days of light driving, and you're concerned the pedal may eventually become impossible to press. The issue likely involves the brake system's pressure release mechanism or master cylinder needing inspection or replacement.

After driving your car 15 miles and stopping, you heard an audible tone with the vehicle off. When you restarted it, multiple warning lights appeared, including a brake warning light. Your car then idled forward and you couldn't stop it with normal braking—you had to apply hard braking to bring it to a stop. The brake system may need diagnostic testing to identify the cause of the warning lights and loss of normal braking response.

Your brakes began making noise when you pressed the pedal, and the problem got progressively worse as you drove. By the time you reached the dealership a couple of miles away, your brakes were barely working. The dealership should inspect your brake system to determine what caused the sudden loss of braking power.

While backing out of your driveway, your brakes failed completely and the pedal went to the floor, causing the vehicle to roll into the street. You heard loud noises coming from the engine compartment. The dealership fixed it by reinitializing and reconfiguring the brake system for about $300.

Your brake pedal may not be working properly when you need to stop. When your wife was backing out of the garage, she pressed the brake pedal but the car didn't stop right away. Several warning lights came on at the time. This happened at around 15,000 miles (though another note mentions 50,100 miles), and the vehicle was only moving at about 5 mph when it occurred. The issue hasn't been diagnosed or repaired yet. Fixing this will likely require a brake system inspection to find what's preventing the brakes from responding normally.

Your car's brakes felt unresponsive when you shifted into reverse after parking for 40 minutes, requiring you to press the brake pedal harder than normal. You heard a noise from the front when braking and noticed the brake warning light turned on, but the brakes returned to normal after turning the car off and waiting about an hour. This issue has happened multiple times during cold weather, suggesting a problem with your car's electronic braking system.

BRAKE FAILURE. PRESSING ON BRAKES WITH NORMAL PRESSURE HAD NO EFFECT. PRESSING ON PEDAL VERY HARD WOULD STOP THE CAR. WHEN DOING SO THERE WAS A NOISE THAT I BELIEVE WAS ASSOCIATED WITH THE ABS BRAKING SYSTEM. THIS COULD HAVE BEEN DISASTROUS IF THERE HAD BEEN A PEDESTRIAN AROUND. TOOK TO DEALER. THEY SAID THE BRAKING CONTROLLER HAD FAILED. THEY REPLACED AND IT APPEARS NORMAL NOW. THIS VEHICLE HAD THE COLD WEATHER BRAKE CONTROLLER UPDATE APPLIED TO IT APPROXIMATELY A MONTH EARLIER.

NISSAN DID NOT NOTIFY ME OF THIS RECALL OF THE LEAF WHICH WAS EFFECTIVE FEBRUARY 26, 2016. WHEN I CALLED NISSAN REGARDING THEIR LACK OF NOTIFICATION ON THIS ISSUE, THE COMPANY, MOREOVER, DID NOT ACKNOWLEDGE THE RECALL CITING A 'SERVICE NOTICE' HAS BEEN IN EFFECT SINCE OCTOBER 15, 2015 OF WHICH I ALSO DID NOT RECEIVE NOTIFICATION! COULD YOU PLEASE FOLLOW UP ON THIS RECALL WITH NISSAN AND INFORM ME OF THEIR RESPONSE. THANK YOU. *TR

LOSS OF ALL BRAKING POWER DUE TO ABS FAILURE.

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 BEVAHIOUR OF THE CAR, BRAKING VERY ABRUPTLY AND HARD. USUALLY, A SECOND TAP ON THE BRAKE RESOLVES THE ISSUE TEMPORARILY, BUT THE SYMPTOM COMES BACK SOON AFTER. THIS IS NOT ONLY AN INCONVENIENCE, BUT ALSO POSES POTENTIAL ACCIDENTS IF A CAR BEHIND THE LEAF IS NOT EXPECTING A HARD BRAKING. CONTACTED THE NISSAN DEALER WITH THE SYMPTOMS, REPLY WAS THAT THIS IS NOT KNOWN TO NISSAN.

TL*THE CONTACT OWNS A 2014 NISSAN LEAF. THE CONTACT STATED THAT WHILE SHIFTING FROM PARK TO DRIVE ON AN INCLINE AND THE BRAKE PEDAL DEPRESSED, THE VEHICLE ROLLED DOWN HILL. THE CONTACT MENTIONED THAT THE BRAKE PEDAL HESITATED TO RESPOND. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 6,400. THE VIN WAS NOT AVAILABLE.
