2018 Nissan Leaf fuel system problems

Filed Oct 28, 2026 · Electrical, Fuel system · PA

My High Voltage battery failed on my car at ~50k miles in 2022. Nissan replaced the battery under warranty. It has failed again now at 110k miles and is way worse than the previous failure. The car will abruptly shut down under load on hills or high speeds on the highway and I will get a P33ED battery fault code. Nissan customer service told me they would offer assistance and after 2 months of waiting on them to find the part number for the battery, they now informed me they won't help. After doing some research, there is a recall out for 2019-2022 Nissan leafs with possible fire related issues because of the batteries and the P33ED code that i am getting is directly related to this recall. I believe I have a recalled battery in my vehicle but Nissan won't offer any assistance because my VIN isn't necessarily recalled. I feel unsafe to charge or operate this car, especially under any type of speed or load and Nissan is offering no assistance in repairing the vehicle or even verifying the battery manufacturer date.

I purchased this EV in 2021 with ~30k miles on it. On cold days ~20 degrees, the battery would drop rapidly under a load (going uphill, high speeds, etc) It would continue to drop until you were not under load anymore. The dealer said nothing was wrong until I had my family in the vehicle and it totally shut down on the highway going 70 mph and i lost all brakes, steering, etc. They finally took me seriously and put a new battery in at ~55k miles in 2022. I continued to have similar issues in the winter on really cold days, but not nearly as bad so i lived with it. At about 100k miles, it started doing a very similar issue, but way worse, and at any temperature. It got so bad i couldn't drive without the battery always being fully charged. Took it to the first dealer who said nothing is wrong with it even though i had videos of it happening. I then called nissan corporate and opened up a case and asked them directly "before i take it to another dealer for a second opinion, is this something that you can offer financial assistance with" and that lady said "yes, we can offer assistance for sure". I took it to another dealer who did some tests and confirmed it needed a battery. Shortly after that, the car now shuts down under even a slight load. A small backroad hill will shut it down and I get an error code P33ED now. This code is related to a battery recall on 2019- 2022 models that can cause a battery fire! After almost 2 months of nissan saying they didn't have the part available, they just informed me they won't offer any assistance because im out of warranty! Not only did i have the battery replaced once, but it has already failed a second time, and they installed a battery that is now recalled but wont honor the recall because my vin is a 2018. I am beyond frustrated with their lack of care about my families safety since this could catch fire! I am hoping to reach out to you for some additional guidance on this situation. Thank you.

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.

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.

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.

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)

I was traveling home from work at approximately 60MPH (speed limit) and I experienced a rapid drop in the state of charge from ~60% to ~25% in 15-20 seconds. I slowed the vehicle to 55MPH and it recovered most of the state of charge. When accelerating to 60MPH a few miles later I experience the same behavior and was forced to maintain 55MPH. I was forced to turn off the electric cabin heater, heated seats, and heated steering wheel as well. I have been able to recreate the issue if the battery is: cold (outside temperature less than 15F and the vehicle has been outside for 8+ hours), less than 60% charged, and put under high load (going up a steep grade/60MPH+) the vehicle will register a battery discharge rate of ~5%/second and continue until the vehicle puts itself into turtle mode, the load is reduced, or I assume, shut off. Battery discharge is "phantom" where the vehicle, when under less load (i.e. slower/slowing), will return to a higher charge, and when no load (i.e. stopped), will return to close to the original charge. Depending on how long the high load is maintained it can drastically reduce the real state of charge on the battery. The Nissan dealership identified it as at least one bad battery module, but no fault codes were registered by the vehicle outside of experiencing turtle mode. This issue forces the driver to slow down to reduce load on the vehicle and abrupt speed changes may be required to keep the vehicle operational. This can put the driver into a dangerous situation of being forced to slow down regardless of road conditions or other driver behaviors. If all of the conditions for the battery listed in the first sentence are met, the vehicle will register a rapid battery state of charge decline, it may indicate turtle mode is active (helps reduce battery load), and it will indicate low charge around 10% state of charge. I have personally experienced all of this as the driver, and any assumptions I have made I have identified.

I was driving at 65 MPH on the freeway and the car was acting/driving normally. Without any warning at all, many lights appeared on the dashboard at the same time that the car placed itself into neutral and lost all power to drive. My speed was reduced so quickly without any notice and I had no pull out lane near me, so I was forced to move across 5 lanes of traffic in rush hour speeds of 60-85 MPH traffic in order to get to safety in a pull out lane while my car was quickly losing speed at 30 MPH and below. I tried to put the car back into drive but it was impossible and the dashboard read "EV maintenance needed". Of note, my entire battery was replaced less than 6 months prior and the Nissan Peoria (AZ) dealership reported no other issues with the vehicle. Upon inspection, the dealership reported the traction motor inverter needs replacement, and again there were no indications this was failing.

When I was drivimg on the highway, the battery rapidly plummeted from 50% to 5%. The car urged me to pull over. After pulling over, the battery rose back up to 50%. If I had not pulled over, the car would have entered "turtle mode," which limits the motor's power and can reduce the car's top speed to below 20mph. These low speeds are especially dangerous on interstate highways and could pose a crash risk.

Vehicle would rapidly suffer from a high energy drain when driving at freeway speeds. Range was reduces from 150 miles EPA, to 80-100 miles. Nissan at first said it was due to the high temperature in Arizona. A few weeks later a "Service EV System" lamp came on, and car would not start the next day after charging overnight. Car stated it was at %80 state of charge at the time. Car was towed to a Nissan service center, and Nissan service determined that some battery modules had bloated battery cells due to overheating after a week of troubleshooting. High voltage battery was replaced under warranty 3 weeks later.
