2019 Nissan Leaf

On 9/17, 2019 Nissan Leaf S 40 kWh lost braking power just after start up. I started the vehicle, placed the vehicle into drive and went to creep through open parking spot. The brake pedal was either dead or lost enough power to feel dead. The vehicle was returned to park in order to stop slow roll. No injuries or damages. Experience seems similar to NHTSA ID 11488058. I don’t recall whether any warning lights came on as I rushed to power down the car. No indicator lights illuminated after restart and vehicle drove home without issue. A few hours prior to brake issue, a humming/ringing sound was heard throughout the cabin just after shutdown. My passengers also observed the sound, which stopped after powering on the vehicle and turning the fan dial. This had not happened before and only occurred once. On 09/18, the vehicle indicated “Warning: Service EV System No Power”. Numerous warning lights were illuminated, a photo taken, and a tow truck scheduled. Two hours later, I went to check whether the vehicle could be placed into neutral. The vehicle started and went into gear without issue and no warning lights illuminated. The vehicle was towed to the dealership for inspection as precaution. My 12V battery was the original battery, so I suspected it needed replacement and asked the dealership to test it. I have read online about other issues from Nissan Leaf owners when the 12V battery is deteriorated. Dealership confirmed 12V battery failed testing. They were not able to duplicate the brake issue described above. The only time that the vehicle provided a warning about the 12V battery was when it generated the warning described above once. Otherwise, no indication that battery needed replacement. Nissan needs to provide a system update to give the driver more specific 12V battery health information. Also address the 12V battery more clearly in maintenance schedule. Vehicle operating as expected with a new 12V battery installed.

Fron passenger lock has been faulty. Door will either latch or unlatch randomly. Dealership has reviewed and stated it is faulty but not their fault despite no evidence of driver responisbility. Car has various electrical issues including auto braking triggering and this lock issue is another example. Dealership is not ackolwedging issues.

A warning light came on with a circle and exclamation mark and when I starting to back up my brake pedal was not stopping the car it kept on going it was very scary , then another warning light came on with a picture of a car and exclamation. Sign and everything stopped working the car will not moved , took the car to the dealer and they said the 12 volt battery was defective

Backup camera fails to display when in reverse. Dangerous reduced visibility of surroundings while reversing vehicle. Called dealership and they confirmed that my VIN is not on the recall list, but I am having the issue! They said I would be charged service to repair this federal safety requirement. Blank screen when entering Reverse mode.

1. The vehicle infotainment screen has been rebooting multiple times over the last few months while driving and the navigation maps screen goes black during the reboot, this is very distracting . 2. The navigation map turn by turn directions intermittently stops working independent of this reboot, causing missed turns, again distracting. 3. The rear camera video intermittently is grayed out instead of showing the rear camera video. I took the car to multiple dealers. The 1st dealer (Nissan of New Rochelle, NY; odometer @ approximately 18,470 miles) said unless the problem is repeatable while in for service there is nothing they can do about it. The other dealer (Star Nissan of Flushing, NY; odometer at 20,470 miles) did a AV software update. Since that AV update on 1/28/2022, Problem #1 and #3 so far have not returned. It may be too early to declare success since today is 2/16/2022. Problem #2 remains! I also noticed that when using Apple Car Play (using a USB wired connection to the Infotainment System) received phone call audio is poor and sounds like someone is gargling. If I switch the phone connection to wireless Bluetooth the audio quality is perfect, so it is not a carrier or phone connection to the network issue. This may be related to problem #2, where the navigation audio stops working. BTW When the Navigation audio stop working,I also lose the ability to change the radio audio. It shows it is changing visually from 0 to +40 on the screen, but the sound audio level remains unchanged. Usually if the car is turned off for more than an hour all returns to normal, at least initially until the next intermittent repeat of the issue. If I turn off the car and turn it back after only a minute or two, the audio problem remains the same.

The Backup Camera only works intermittently and if it is not working it will not begin working again unless the car is completely turned off and restarted. The failure seems more likely to occur if the car is started and then quickly put into reverse. The failure seems less likely to occur, but still does periodically, if the car is started and then not put into motion until 10-20 sec after the dash start-up graphics have finished. When the camera is failing the display is solid magenta colored with static-lines scrolling through it. The safety issue is that the rear camera cannot be used. We have not yet shown this problem to anyone else. There were no warning lights or alarms indicating a failure. The failure occurrence was very infrequent when we bought the car (new) in 2019, but now is happening at least 50% of the time that we back out of our garage.

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.
