2023 Nissan Ariya: sudden loss of power

Filed Oct 11, 2026 · Transmission · SC

My 2023 Nissan Ariya was making a cicada/whining sound under low acceleration. This was found by my local Nissan dealer to be a defect with the reduction gear. The dealership replaced the reduction gear under the powertrain warranty. This issue was present at just under 50,000 miles. Without replacement, the component could fail entirely leading to a total loss of power to the wheels, posing a safety risk while driving. There were no warning lamps on or any indication of a failing component other than the sound getting gradually louder. It took some research to figure out if the sound was normal or not. If I had not researched and inquired with my dealer, the problem would have gone unchecked and put me in danger of losing power while driving.

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.

the car lost power in the middle of the freeway -and decelerated; in a highway with speed limit of 65mph while driving in I-680, all of a sudden the car slowed down from 65mph all the way to less than 20mph - displaying "power reduced - 0% battery" ; even it was recently fully charged - I was able to drive the car - back at 20mph speed - went straight to the Nissan dealer/service - where I left my car - and. was given a loaner car. the warning lamp ONLY appeared as soon as the car decelerated / slowed down

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!

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.

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).

My car had an 80% charge and I was going 75 MPH on a major highway. for the second time in five months the Ariya inexplicably shut off, went into neutral. I had to navigate three lanes to get off the nearest exit. The car immediately lost all power and decelerated from 75 miles a The car immediately lost all power and decelerated from 75 MPH to 25 before I could get to the nearest exit.This is so unacceptable. I do not feel safe in this car.
