2023 Nissan Ariya Electrical Problems

The vehicle’s EV system and related electrical components appear to be malfunctioning, causing repeated “EV System Off” error messages and rendering the vehicle inoperable. The vehicle is currently at the dealership and available for inspection upon request. The defect created a significant safety risk because the vehicle became unreliable and could unexpectedly fail to operate, leaving me stranded and without dependable transportation. This placed both myself and others at risk, especially if the failure occurred while driving or in traffic. Yes, the issue has been repeatedly reproduced and confirmed by the Nissan dealership. The vehicle has been towed to the dealership approximately five times for the same or substantially similar issue, and multiple repair attempts and part replacements have been made. The vehicle has been inspected by the Nissan dealership and Nissan Consumer Affairs has been notified on multiple occasions. Repairs and diagnostics were performed between March 20, 2026 and April 10, 2026, and the same issue reoccurred again on May 19, 2026. Yes, warning messages appeared prior to the failures, specifically the “EV System Off” warning message. These symptoms first began prior to the initial repair period in March 2026 and have continued to reoccur despite repair attempts.

Incident

May 19, 2026

At low speeds after startup, the car automatically shifts from drive into neutral. The car will be locked in neutral, not letting you put it in park, drive, or reverse. To get the car back into drive, you must come to a complete stop, turn the car off, back on, and floor the accelerator. Failure to floor the accelerator will lead to the car getting stuck in neutral again. I have pulled out into traffic on numerous occasions and had the car die in the middle of the road, forcing me to come to a stop and fully turn it back on, sometimes multiple times. No warning messages appear.

DEFECTIVE COMPONENT & FAILURE MODE The vehicle suffered a failure in the 12-volt battery system, potentially involving the DC-to-DC Converter or the associated charging logic. This malfunction caused the lead-acid 12V battery to be severely overcharged and boiled while the vehicle was plugged in and parked. CATASTROPHIC SAFETY HAZARD The failure resulted in the release of highly toxic and flammable gases into an enclosed residential space (my garage), posing an immediate, life-threatening risk: TOXIC GAS POISONING: The boiling battery released a massive amount of Hydrogen Sulfide gas, identified by the distinctive, strong rotten-egg odor. H2S is a cellular asphyxiant and is fatal at high concentrations. EXPLOSION/FIRE RISK: The boiling battery also released highly flammable Hydrogen H2 gas, creating an explosion hazard inside the closed structure of the home. CHRONOLOGY OF EVENTS Tues, 11/11/25 (approx. 5:00 PM): Noticed strong rotten-egg smell in the garage while the vehicle was charging. 5:30 PM: Called local gas company due to fear of a gas leak. 6:30 PM: The smell was still strongly detectable, indicating dangerous lingering concentrations. Suspecting the car, immediately unplugged. 7:00 PM: Identified the car as the source and moved the immobilized vehicle outside. 9:05 PM: Contacted Poison Control due to chemical inhalation/exposure risk. (immediate / risk of delayed symptoms). MANUFACTURER CONTACT & CURRENT STATUS Manufacturer Contact: I have notified Nissan Consumer Affairs of the safety hazard and received Case Number: 55990119. Current Status: The vehicle is currently immobilized and will be sent to dealership for repair. The defective components (battery and converter) are intact. Medical Status: I sought medical consultation and am monitoring for delayed neurological or respiratory effects (pulmonary edema) known to occur after H2S exposure.

I had just left the [XXX] on the [XXX] when our Ariya suddenly lost power at highway speeds. It felt like a very dangerous situation, because there are very long distances between exits in this area, and the shoulder is somewhat narrow in spots. The high voltage battery had been DC fast charged to 95% at said service area minutes earlier. But the display suddenly went to 0%, turtle mode appeared, and the message “Warning Service EV System” showed on the display. For some reason, the windshield wipers also activated momentarily, despite it being a clear summer day. It was not possible to maintain speed, as the car had a power limit of about 10%. I was fortunate that we were able to limp the ~10 miles to the next exit behind a very slow RV. However, the car slowed down dramatically when going uphill. It was a very white knuckle experience. Once we made it off [XXX], I was able to slowly coast into a gas station parking lot and collect myself. I tried turning off the car and turning it back on, but the message did not go away. Since I also carry tools when traveling, I then tried disconnecting the 12 volt battery for a minute and reconnecting it. Fortunately, that made the error go away. Having a suspicion that the 12 volt battery could be at fault, I replaced the OEM flooded lead acid battery with an AGM battery at my own expensive. The next day, I took the vehicle to Poughkeepsie Nissan in Wappingers Falls, NY to be looked at. The write up is included with the submission. The dealer was not able to duplicate the issue, but they did see error codes stored within the car’s computers.

This is the fourth time this has happened to us during normal driving. I pulled out onto a highway and suddenly with no prior warning, the car lost all power and went into what I can only describe as a "limp mode" and wouldn't go above 5 mph. I had to quickly pull off the road as traffic was catching up at highway speed. The dashboard flashed "Malfunction, see owners manual" and we had an orange triangle with an exclamation point as well as a circle with exclamation point with a wrench next to it. The traction control light and car with exclamation point were also lit up. After limping to a cross road we turned the car completely off for 5 min and when we restarted it, it worked normally. The same thing happened July 25, 2024 and I had the car in the dealership. They said they could not recreate the issue even though I showed them video of the dashboard acting strangely. The service manager said he believed something had blocked the front bumper sensor and that it should be fine now. We have already performed both software updated recalls and since then, it has happened to us twice more. The battery was at around 80%, had just been driven by my wife for around 30 min with no issues, was turned off in the driveway for about 15 min and then we left again. It was extremely cold during this issue (temps around 10 degrees F), but this has also happened during normal temps in the summer and fall.

Incident

Nov 4, 2024

I was on the highway and the car completely shut off. My electric battery which was at 50% and over 150 miles died. I had to veer off quickly to the side of the road and my steering wheel then locked. I've seen some forums on Reddit of this happening. The dashboard flashed "EV System Off" and the miles and % battery went to zero. It was incredibly scary since it was at night and the potential for a serious accident could've occurred. I had to be towed as well and the police wanted me off the road as quickly as possible so they called their own local towing company to do so. The Route 9 Nissan in MA looked at it and simply said it needed a "software update". Which is alarming because my whole car shut off. Nissan corporate and their roadside assistance from beginning to end have handled this horribly. I am over 8 days removed from the report and still nothing has been resolved. They even had the gumption to tell me on the phone that the towing charge I got would be a courtesy and they aren't sure if they could give it to me.

Incident

Aug 9, 2024

Driving on the freeway this morning at 72% charge, approximately 5 miles into my 41 mile commute, message appeared on dash that battery charge was critically low, charge immediately. When this appeared the car was no longer showing the 72% charge, but 0% instead. The initial error was then replaced with "Warning Service EV System Power Reduced" and still showing 0% charge. Under reduced power I made it to a charging station 3 miles away and after a large number of attempts, finally got it to start charging. Immediately, the charge % returned to 70% and successfully charged to over 80%. To be safe I returned home instead of trying to finish my commute, as it was just past 3:00 AM and I didn't feel safe trying to complete the drive. I've also noticed since this has occurred the Nissan Connect app is no longer updating from the vehicle. If this is the same problem that others seem to have had, this becomes a highly dangerous situation both in the safety of the driver/passengers, but also everyone else on the road as the car goes to a reduced power mode!

Incident

Jan 5, 2024

While driving on the highway on Dec.2 2023, my car suddenly displayed "Service EV Error" and "Reduced Power" warnings, along with the battery level to plummet from 89% to 0%. Upon noticing the warnings, I promptly activated hazard lights and maneuvered to the emergency lane. However, my attempts to maintain control were met with a gradual deceleration of the vehicle. Despite repeatedly pressing the acceleration pedal, the car failed to respond as expected, creating a hazardous situation on the high-speed highway. The urgency of the situation heightened as the reduced power hindered my ability to keep pace with traffic flow on the highway. The potential for a high-speed collision or other safety hazards increased, given the car's limited control and responsiveness. This occurred in an environment where other motorists were navigating the highway at significant speeds. After multiple unsuccessful attempts to address the issue, I reached a ChargePoint at a speed of 25-35 mph, but the connection failed, leaving the battery completely depleted. Seeking assistance from the dealership proved challenging initially, as they couldn't pinpoint the problem. With unresolved safety risks, the dealership recommended a tow. Unexpectedly, after restarting the car, the issues disappeared, and the battery level returned back to 89%. During a 250-mile drive post-incident, no further problems occurred. Days later, I brought the car to the service department for further inspection. They identified it as a junction box problem, ordered a replacement, and I am currently awaiting updates from them. They did not mention that the problem was reproduced by them but did mention they have some other customers encountered similar issue on their Ariyas.

Incident

Dec 1, 2023

When I got in the vehicle after work on 11-22-23, it displayed a “EV System” error alert and “Power Reduced” alert. The vehicle would only accelerate extremely slowly and would only go about 25 MPH. Trying to go up hill to my house it would only go maximum of 10 MPH. I barely made it home. I left it at the dealership the next day (which was a national holiday) and they examined the car on 11-24-23 but could not find anything wrong. I have been told to drive the car and bring it back if the message occurs again. My EV battery seems to be no longer holding a good charge at this time. I am concerned about the safety of the vehicle at this time.

While coming to a complete stop using manual braking the vehicle appeared to lose power. The infotainment system went black and reset. The car itself did not need to be restarted and the manual brakes were still responsive. Additionally there is a recurring loud popping/cracking noise during normal driving (not charging).

Incident

Sep 18, 2023

The car spontaneously shut down. "EV OFF" displayed on the screen. I was in the middle of the road and unable to turn on the car or shift into neutral to push it off the road. I had to wait over an hour for a tow while in the road. This appears to be an increasing problem as many owners are reporting the same issue on the Nissan Ariya electric SUV Discussion Group page on Facebook.

Incident

Jul 14, 2023

Car abruptly changed from mph to kmh. All safety aspects stay in mph, including speed limit and alert. So while on highway going 65mph, suddenly speed said 116kmh. But speed alerts were still saying “65”. Pro pilot on and car abruptly slowed down towards 65kmh on highway. Only way to change mph to kmh and back is to have car at complete stop, scroll to menu on steering wheel. Click it. Scroll to language. Click that. Click three more times. These options are completely locked out while the car is moving. Due to the danger of this happening on the highway, nearly avoiding getting rear ended, took to dealer. They reported nothing wrong. Reported to Nissan who said nothing wrong. Happened again today, not on Highway luckily. There are online posts of this happening with other Ariyas, but not on Highway. Again, if wanting to do this on purpose the car must be stopped and at least five explicit actions. Moreover, the safety measures on the car do not discriminate units, only numbers which makes this go from an annoyance to something that almost caused a high speed accident. Nissan has again been made aware, but lacks responsiveness.
