2018 Nissan Leaf

This is the second high-voltage traction battery failure on this vehicle. The original HV battery failed and was replaced by Nissan under warranty at an authorized dealer on XXX, at approximately 59,000 miles. The Nissan-manufactured replacement pack has now failed after approximately 16 months in service. On XXX, at ~74000 miles, the vehicle was diagnosed at Johnson City Nissan ([XXX]) with an internal short circuit within the high-voltage battery pack The error codes were P31E7-00 0B and P0AA6-1A 0B. Dealer service personnel identified the condition as an internal short in the pack. Due to the fire risk associated with an internal short in a lithium-ion traction battery, I declined to take possession of the vehicle, which remains at the dealership. An internal short can lead to thermal runaway without warning, whether the vehicle is being driven, charging, or parked. The failure of a factory replacement battery pack in 16 months, following the failure of the original pack, indicates a potential manufacturing or design defect in Nissan's service replacement HV battery packs for this platform. I am reporting this so NHTSA can evaluate whether other Leaf replacement packs exhibit similar internal short failures.

Car was fast charged on July 9th. 2026. After fast charging from 13% to 80%, and driving for a few miles, the overheating warning came on and car was forced to stop on the side of a busy highway until the engine cooled off. While there is an active recall for a similar problem (24V700), my car is not included and we were not notified.

Fail component: mechanical linkage (transmission rod) between the motor and the wiper arms. The ball pops out of the socket resulting in the wipers not working despite motor running. This happened with full speed wipers running. I repaired it, and two weeks later it disconnected again while running wipers at full speed in heavy rain. This left me without windshield wipers in heavy rain on a road with a 55mph speed limit. If I had not been able to quickly exit this would have resulted in significant risk to myself and other motorists. I was able to drive home on slower side roads, but the lack of wipers remained a safety issue. I have not taken in into a dealer or shop to have it reproduced. I will take photos while fixing. No incident or police reports were filed. There were no warning lights or alarms before or after this occurred. It seems this is a known issue that is common to Nissan vehicles including the leaf.

This vehicle is equipped with a feature known as "e-pedal" also known as one-pedal driving which is quite common on EVs. When this mode is activated, the accelerator pedal acts as a speed command (vs. power) and when the pedal is not depressed, the vehicle applies brakes until it comes to a standstill. Recently, the system has demonstrated a fault condition, where the Vehicle Control Module (VCM) issues a fault warning and disengages the e-pedal mode. This appears to occur randomly after the vehicle has been at a standstill for over one minute (e.g. waiting at a traffic signal) where the driver is using the one-pedal system vs. continuously applying pressure to the brake pedal. The safety issue is that when the system detects a fault and disengages e-pedal, the vehicle starts to move forward, requiring the driver to take immediate action to stop unwanted motion. This can lead to a collision with a vehicle or pedestrian in front of the vehicle. The desired behavior is that when the VCM detects a fault with the e-pedal system, it should engage the Park mode and prevent the vehicle from moving forward. The driver must then depress the brake pedal and affirmatively command the Drive mode before moving. Just disengaging the e-pedal (brake) without prior warning of a fault is a safety hazard.

On 1/6/2026, as I slowed down as I was turning into my parking lot. I had Eco and e-pedal ON for regenerative braking. As I was turning into the parking lot, the car suddenly accelerated, went over the curb, across the street, over another curb before finally stopping after colliding with a structure. I was driving slowly and distinctively recall braking. This sudden unintended acceleration put safety at risk and caused significant property damage. There were no warning signs or messages. The car is in the yard now and will be available for inspection.

The front windshield wipers on this car fail in light ice or snow. They've broken every winter I've owned this car (four years). This results in me driving around without front windshield wipers until I can get it fixed, watching the weather forecast and hoping I don't get caught in rain or snow. It happens despite my best efforts not to use the wipers in freezing weather unless absolutely necessary, going so far as to drive in light snow or rain without wipers to avoid breaking them. I've fixed it myself (not easy, especially in winter weather) and paid a mechanic to fix it for me at least three times. Most recently, the mechanic replaced the entire motor and linkage assembly which was extra expensive, but the right wiper broke again this Thanksgiving. (Until this last time, both wipers have always broken together.)

I was traveling north on Freeway 57 at approximately 70mph. The dash lit up red with 12v and charging warnings. Power was shut off and car went into Neutral and warned me to pull over. This is an incredibly busy freeway and I was in the far left lane. I barely made it to the shoulder coasting before car started shuttering and jerking and stopped rolling. I could have been killed.

Vehicle failed inspection due to a rusted out front subframe which seems premature for a 7 year old vehicle with 27,599 miles on it. According to local mechanic, they've seen this issue with many Nissan Leaf models. This is a critical piece of the vehicle hence it failing inspection due to rust. The vehicle has not (yet) been inspected by the local dealership to confirm the issue and there were no warning symptoms prior to it failing inspection.
