2018 Nissan Leaf electrical 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.

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 the federal safety agency 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.

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.

The contact owns a 2018 Nissan Leaf. The contact stated that after his wife had parked in a parking garage, the vehicle was restarted and driven in 17-degree Fahrenheit weather when the vehicle lost motive power. The "Service EV System, No Power" message was displayed. The contact's wife pulled over and had the vehicle towed to the dealer. The contact stated that the battery had previously been replaced. The dealer determined that the failure was caused by a frozen battery. After the battery had thawed, the battery was able to be recharged. No repair was recommended. The contact related the failure to the variable voltage control system and the 12-Volt battery amp-hours (Ah). The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 79,545.

Vehicle randomly shuts down when car is underload traveling at highway speed up an incline and with the climate on. Diagnostics are showing multiple cells that are bad in the main battery manufacturer is stating that it is normal wear and it is normal. I’ve only had the car for 300 miles. It was a previously owned car that was supposed to carry an eight year warranty on the drivetrain and battery. They are not honoring the warranty and the vehicle is dangerous to drive and in fact cannot be driven the situation occurred on three occasions where the vehicle just randomly shuts down on the freeway in the middle of the highway. This is a serious concern that will definitely cause injury or death. I attached photos of two occasions when the battery discharged almost immediately, and the one photo shows on the vehicle was completely disabled. I have more supportive photographs and computer printouts from diagnostics if requested..

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.
