During the last 3 winters I have noticed the car do something strange when going up an extended highway inclines. The battery % along with the estimated miles left will drop suddenly (~40% in a minute) and when I would go over the top of the hill most of the battery % and miles would return. During the 2021-2022 winter, I noticed this happen only once or twice. During 2022-2023 winter, I noticed this happen more often but I did not know what was causing it except it seemed to only happen on very cold days and also when the battery % prior to the drop was around 50% or less. During the current 2023-2024 winter, this issue became common. It no longer had to be very cold but just an extended incline and battery at 50% or less. It usually happened between exit [XXX] and exit [XXX] on [XXX] in New Jersey. It has become so common that I was able to record it. The videos show the car will lose over 40% of battery in about a minute. However, once I would go over the hill most of the battery % would come right back. In one video the -??Battery charge is low Charge now-?? warning is triggered. On a few occasions, when I had around 30% of battery prior to going up this hill and the battery started to drop suddenly, I had to make a rapid emergency stop on the right shoulder midway up the hill. When stopped the battery would recover back to around 30% and I was able to get over the hill. This obviously created a safety concern. My car battery is still covered under Nissan-??s EV battery warranty. I have taken the car to two 2 Nissan dealerships. One of the dealership was able to replicate the issue, but stated the only way they will approve the warranty repair is if they disassembles the battery. They stated once they approve the warranty repair they can order the battery but that it might take up to 8-9 months to get the battery. They stated that during this whole time my car will be inoperable and Nissan will not provide or reimburse for a loaner car.

About January 19, 2022 when the temperature was about -10 degrees F I drove my 2019 Nissan Leaf about 5 miles. When I turned on the car the battery level was at 60%. After I had been driving for about ? mile I got a dashboard message that the battery was cold and power would be reduced. I got a similar message a few days before which did not result in any difference in power levels, so I ignored the message. At about 3 miles I had to go up a 10% grade hill of about 1/4 mile in length. As soon as I started up the hill and was accelerating I got the power reduction message again. At that point I was traveling about 50mph. Then in the next 10 seconds, and while I was about half way up the hill, the battery indicator on the dashboard dropped all the way down to 1%. The car lost all of its power and I had to pull over to the side of the road. As soon as I stopped the battery indicator started to rise and within the next 30 seconds had returned to 60%. I continued up the hill, and noticed that the power was decreasing and the battery indicator was dropping again. I made it to the top of the hill and stopped again. The battery indicator returned to 60%. I had to stop one more time to allow the battery to recover, but made it to my destination without further problems. Two hours later I started for home and the car operated normally. Between that day and February 5 there have been no further incidents, even though early morning temperatures have ranged from -7 degrees to -28 degrees on 13 days. I took the car to Freedom Nissan in South Burlington, VT on Feb. 2. However, they told me that there was no record of such an incident on the computer and they would do nothing without such a record. To have the car go from full power to zero power in a 10 second period is a very disconcerting experience. It should have provoked an error message in the onboard computer. I think this is a safety problem and would like you to look into it.
Vehicle suddenly loses power while driving, no warnings prior to power loss. 1st incident vehicle lost power and all check engine lights came on. Unable to shift gears or accelerate. Towed to Nissan. This has happened twice again in the past week. Complete power loss while driving, have to coast to a stop and get towed again! 3 times total. Huge safety issue to be without power in the middle of the road. Nissan tried to -??reset-?? it but this has not worked. The 3rd time we picked it up from service it happened again less than a mile away. Screens say -??When parked apply parking brake-?? while I-??m driving. Other screen said -??Power Supply Failure. To avoid accident injury or death DO NOT DRIVE-??. This car is dangerous.
